Title: Coolant flush
Post by: Entwood on 16 September 2007, 00:02:30
How many times do you think it needs emptying/refilling ??

Done it 5 times today, with a 5 mile run with heater on max hot ( :o :o phew !!) between each empty/refill - and yes - it was left to cool down after each run !!

Still getting manky dark red/brown fluid in header tank and from radiator drain on each empty, runs clear after about 5 minutes of hosepipe action in through the header tank.

I intend to continue this tomorrow until it is clear after a run, is this wishful thinking ?? ...  then top up with 50/50 mixture

How exactly do you do it?

After an oil cooler failure, 30 odd times should be enough ;D

May be worth a spot of forte cooling system flush....

I do the following

Drain, fill with water, warm-up engine, drain.

Fill with water and 2 bottles of Holts regular rad flush, warm-up engine and run for 10 minutes, drain.

Two more drain and fills.

Last drain, them add 5L of Vx red antifreeze.

This seem to work well, though the secret is repeating it every year.

All the petrol engines follow same procedure...   ...the 2.5TD is different in that it has a block drain plug.  The petrols don't have this, so you only get half of the coolant out with each drain.

As I keep saying, the offer of assistance is there if you are prepared to pop up here.  Vauxhall 'Red' is about £12 from dealer at retail prices.

Tap water is fine, esp if not too hard (I know Oxford is a little hard, should be OK).

do you have any spare anti-freeze?

If you have access to a hose then this will aid you no end, drain the radiator with the drain off valve when cold. Add a bottle of forte cooling system flush and top up with water to the cold mark. Run the engine or go for a drive to get the engine up to temp and get the flush around the whole system. Run the heater fans on full and hot settings to help get the heater matrix flushed.

Stop the motor and drain the radiator via the valve.]BEWARE THE WATER WILL BE VV HOT]
REMOVE THE RAD CAP SLOWLY  and wait for the engine to cool, remove the hose from the rad to the engine on the left of the engine[ silver pipe] and more water will pour out here.
if you have a secondary coolant pump bolted to the inner wing below the header tank remove one pipe and place your hose in this hose and flush through the heater matrix untill clean water emerges. open the rad valve again and now place the hose pipe into the disconnected rad hose and back flush the rad. close the rad valve and refit the rad to engine hose and coolant pump hose and refill the header tank.
Start the engine and the header tank level will drop as the water is taken around the system so keep an eye on the level top up untill the level stays the same. drain and repeat untill you have cleared all the flush and the water comes out clear. It takes a while to flush the v6 but it is worth it in the end.

Thinkit would be worth taking out the thermostat next time I do mine (like some of you did say, but honestly it didn't say it on my bottle >:()
I am still getting green stuff in my reservoir.... keep trying to dilute it by dropping the water, flushing  then refilling with clean water....... will get there in the end ::)
Title: Re: Coolant flush

No, don't take the thermostat out just yet - that job is a little more challenging ;)


In the week, I can only do evenings, as I work all day.  Tuesday evening may be difficult, Wed evening may be better, I'll check...

Thanks to all :)  Water is now very nearly clear, its had 8 changes .. and the 7th had a 250 mile drive :(. Mrs E dinked her clit, needs a new bonnet and headlamps ... found a source let me have them all for a tenner .. trouble was 125 miles away. Bonnet now fitted .. lights after work tomorow with luck. Then a final water flush and in goes the antifreeze :)

Off topic ... 250 miles at around 70-75 ...  80% motorway  averaged 36.7 mpg  :), and the boot was open all the way back with a clit bonnet sticking out of it !!

Forte not available from Halfords - thye only sell the rather poor Holts stuff, so try other factors.  Near you is Express factors on Pony Road Industrial estate (opposite BMW plant), and Holoway Autospares (opposite Smithe and Low on Holloway, Cowley).

Yup, I know Oxford - Mrs TheBoy came from Horspath, where her folks still live, and her brother lived down the Cowley Road for a few years (before moving to Bicester).

You may want to call them regarding Forte Cooling System Flush, very few places sell it.  Ebay is an option, a couple of people on there sell.

But before Forteing it, just flush it through wil water a few times first.

Vauxhall's own 'Red' antifreeze is recommended, unfortunately, I don't have any spare (unusually), and may not get to dealer for a few days (I need to get to one to get some more oil and antifreeze myself).
Title: Re: Coolant flush
Post by: Entwood on 16 September 2007, 22:07:17
Just for info ... don't know if this applies to all dealers.. but neither of the 2 Swindon branches (Skurrays) have 5 litre antifreeze available. The Drove Road one had 1 litre versions and when I produced the TC the guy manually amended the computer to give me 5x1 ltre at the 5 ltr price, which I thought was rather nice ... only about a £1 difference but every little helps .. and I thought his attitude was rather excellent  :) He even apologised for the seals that were not in stock.

My local dealer in Banbury doesn't stock the 5l ones either, so 20l drums....

Title: Re: Coolant flush
Post by: Entwood on 16 September 2007, 22:18:47
5 litres is all you need .. the system holds 9.7 ltrs (manual) or 9.5 ltrs (auto) in total  .. and you put in a 50/50 mix    :)

Only if you're doing 2 V6 cars! ;)

They take about 10 litres so once you've drained half the system of clear water the addition of 5 litres will give you a 50 50 mix of water / anti freeze.


Bugger .......... beaten to it again! ;D
Title: Re: Coolant flush
Post by: RolandL on 16 September 2007, 22:22:14
The mix for coolant is usually 50/50, so one 5L will give you 10L of coolant, more than enough for what you need  :y

if i knacker my car, im coming after all of you like The Terminator! ha ha ha

i dont know if any of you have given your thoughts on "oil types"
i know the Omega 2.5V6 uses 10x40 oil ?
i was gonna buy some "Magnatec" £39.99 for 2 x 4.5 litres
is this Quality oil? or is it all a big con with what they state?
i know a lot of people say get GM, but as i dont have a clue, i thought i`d ask

Save your money mate and buy GM semi synthetic, if you have acces to a Trade Club Card it's about £8- a metric gallon or 4 for the price of 3
Title: Re: Coolant flush
Post by: Wayne on 18 September 2007, 15:11:30
 :-?  did i say something wrong?  lol

surely Magnatec MUST be better stuff, just been reading about it and apparently its NOT all hype, it does do what it says is does, read it on some forum somewhere, Honest John i think!

i dont have a trade card  >:(
Title: Re: Coolant flush
Post by: Kevin Wood on 18 September 2007, 15:28:38
I would try to see through the marketing hype and look to the specifications of the oil. Both are ACEA A3 rated oils, which means they're adequate for an Omega.

Changing the oil regularly (read: much more frequently then the manufacturer's recommendations) is far more important than the choice of oil, IMHO.

Now. let's try and get off the oil subject.

Kevin
Title: Re: Coolant flush
Post by: Wayne on 18 September 2007, 15:30:54
okay - no problem, i apologise for even discussing it!!

i guess its down to each persons choice, but i will be getting Magnatec anyway, i cant see the harm apart from a few quid extra


Laters....
Title: Re: Coolant flush
Post by: Dazzler on 18 September 2007, 15:31:27
We just use the GM oil because with a Trade Club card you cannot beat the price and value of the stuff. If the oil is changed regularly then you don't need the expensive hyped up stuff.
But at the end of the day the choice is yours, we are only giving advice/recommendations.
Title: Re: Coolant flush
Post by: ians on 19 September 2007, 00:09:00
Wayne - just so we're clear mate..  when you have flushed and drained a million times,

-pour in the WHOLE 5L can of neat red antifreeze.  Then top up as necessary with water.

Reason being is that you will already have about 5L of water sitting in your engine that you cannot drain out (unless you're doing water pump, but that's another story).

If you premix the antifreeze to 50/50, you'll end up with about 25% strength which isn't enough.

A straightforward coolant change is really easy peasy, oil change likewise, although I inevitably get used oil everywhere,  so go on - have a go.  Plenty of advice here if you get stuck :y

im actually looking forward to doing those 2 jobs, it might make me feel more Manly, ha ha ha ha

i dont have access to a jack though! so im just gonna have to get a bad back crawling underneath etc

thanks for the tips, i was a bit worried about having to mix 50/50 etc
so i just pour the whole tub in then?

You won't need a jack to reach the rain plug, it's on the passenger side of the rad  - at the bottom. You might need some pliers to undo it the first time .. I did.

Yes when you have clean water in the system just drain off what you can from the drain plug (which will be about a gallon) and then add all your 5l can of antifreeze - after you've tightened the drain plug up again though!   ;)   :y

Not a fan of any of the Castrol oils, never have been.  I think their TV advertising is better than their product.  To quote a family member who designs cars "best flush for engine is Castrol GTX, as it doesn't last so you'll need to drop it out again quick"

Seeing as Vauxhalls own semi synth is around £8 per 5l, bit of a no brainer really.  The Vauxhall stuff is pretty good, and goes in all my cars (2 Omegas, 1 Rover, the Kawasaki, and even the lawnmower)....

You need to double check what oil filter your car uses - up to 1998 its normally a spin on type (£1.40 ish from dealer on TC), from 1999 normally paper element (£4.50 ish from dealer on TC).

You can get a TC card for £20, so pays for itself straight away.

Oil is like soap powder. You can't see what's actually going on inside your washing machine, just like you can't stick your head in the crankcase and see how the magnetic paritcles of oil are clinging to your bearings and protecting them, and rubbish like that  ::)

Your clothes come out of the machine clean regardless of the brand of powder you use and your engine doesn't sieze regardless of the oil you use.

How do you market such a product? Dream up some bull**it, put it in a glossy TV advert and wait for the gullible to bite!

Meanwhile, those without such huge advertising budgets can sell the same product for half the price.

You'd think so, given that you're getting about half as much product with the paper element but not so IME...

I guess the spin-on filters they can buy in dirt cheap because they're made in huge volumes whereas the paper elements may not be benefitting from such an economy of scale yet and have to be OEM produced.

Nope, the 'eco friendly' disposable paper element are 3 times the cost of the spin on filters....

Title: Re: Coolant flush and more!
Post by: Wayne on 22 September 2007, 14:28:24
Thanks mate!
i got your PM, but desperate to get it done today, but thanks anyway buddy
will come see you next time when it needs doing

how often should i do a coolant flush and change do you all think?
after how many miles?
also, how about oil changes.... how frequent?

i bought some RED Antifreeze from VX in Oxford today, and i ordered a NEW Rear windscreen wiper arm with VX wiper blade, even though my blade is 2 days old made by Bosch!
want to see IF the VX blades are any better

anyway, the antifreeze cost me £11.39 for the 5 litre container
the wiper arm and blade cost me £23.44

i have just come indoors from doing the 1st stage of my 1st coolant flush, im very proud of myself  ;D
i tried to get the radiator plug out and it wouldnt come off, so bit of WD40 cured that!
im not sure IF its ever had a coolant flush, no way for me to check, i know it hasnt had one done since i have had the car in 5 years!
i drained all the horrid blue gunk out etc, then flushed it and re-filled it another 4 times, infact after the 3rd attempt the water was nice and clear anyway.... then i filled it up again and added the Forte coolant flush and run the car for 35 minutes with the heater on Maximum while i had a cuppa
will now leave the car for a good 90 minutes to cool down (should be enough?)
will then empty again and refill and flush 2 more times, just incase!
then its time to add the new antifreeze, add the full 5 litres in 1 go ?
does that sound about right?

let me know IF what i have done so far sounds hunky dory?

my dads mate has ordered the other parts for my oil change
genuine VX oil filter, and i have chosen 10w/40 Castrol Magnatec, my choice i know and my preference

just need to get an annoying 4 inch spot of rust done on the rear drivers side passenger door near the window and im all done, well............ errrr..........for now!

strangely, that burning oily rubbery smell isnt as strong!
dont know whats happened, seems to be less noticeable
i would really love to know about my rocker gaskets and IF they are all ok


Laters guys  :y
Title: Re: Coolant flush
Post by: Wayne on 22 September 2007, 19:10:05
I spoke to soon!

what the hell have i done wrong?

i done my coolant today with all the flushes and drains, 5-6 times! and with forte coolant flush etc etc

the water was running nice and clear on the final drain, so filled up the car with the VX antifreeze, nice and red!

left the car for 2 and 1/2 hours, just checked now and the coolant has gone back to murky blue!
whats gone wrong?

do i have to go an buy MORE red antifreeze and do it all again?

i dont understand!
Title: Re: Coolant flush
Post by: hotel21 on 22 September 2007, 19:17:31
Bet you didn't run the engine between flushes.......  

By draining/filling you only get half the water out.  The remainder is still within the engine block and system and needs the engine run for a wee bit to circulate the water.  That dilutes the mix to a paler shade.  Drain, refill, restart and circulate then drain again... and again ... and again.   Then it will run clear, drain, refill and away you go....   :y
Title: Re: Coolant flush
Post by: Wayne on 22 September 2007, 19:23:20
bugger that, i been at this all day, poured 5 litres of antifreeze in etc
i didnt know you had to run the engine everytime you flushed it
trouble is i heard that IF you keep doing that, and then you add cold water, you could crack something by adding cold to hot?
IF i have to wait for the engine to cool down on each flush, that will be about 12 hours to get it all sorted?

so, what was nice red antifreeze is STILL back to what it was!

damm it!

i knew id mess it up, only i could!

yep afraid your looking at 8 even 9 flushes for that perfect pink tinge......

Ideally, run it to temp, cool it down then drain/refill.  All you need is to drain/refill, run it for, say, 5 minutes to circulate the water then drain etc several times.  Yes, it will take a few days this way.

Alternate if you feel confident is to place a hose in the water expansion tank and balance the amount of water going in with the amount draining out the radiator drain.  Start the engine and keep a GOOD eye on whats happening, water level wise.  Do not let it fall below minimum.  Leave it running (still watching  ;) ) until it all runs clear.

damm it!

i knew id mess it up, only i could!


You haven't messed it up, if it hadn't been done for ages then you can only have improved the situation, think of it this way..... you haven't got so much flushing to do now!  :y

right, so im back to VX on Monday then to buy ANOTHER 5 LITRES of the red stuff?
and i wasted £16 on Forte coolant flushing stuff that just p****d out all over the place

im VERY fedup

so, Monday....first of all, it`s empty the radiator again from cold? drain everything out straight away
put the radiator plug back in, fill up with water, start engine and leave running for how long exactly?
then let engine cool down, how long to cool down so i dont scold myself with the pressure from the header tank?
then empty again.... refill with water, plug back in, and do this how many times?
how do i know when the water is gonna be clear so that when i refill with the red stuff it actually stays red???

im stupid!
Title: Re: Coolant flush
Post by: Wayne on 22 September 2007, 19:42:25
okay, so im gonna do the HOSE thing!
what temperature do i run the car to on the gauge?

do i start the engine once its cooled right down and leave the radiator plug on the floor, and then just let the cold water run from the hose into the coolant bottle into the engine thats actually hotting up when its running? and do i put the heater on MAXIMUM like before on each turn of the engine running?
wont that crack something? by adding cold water to a hot engine? cylinder heads?

im just worried that i do all this, and then the murky blue stuff re-appears after i let it settle for 2 hours....
i seem to just be wasting money i can ill afford

Title: Re: Coolant flush
Post by: hotel21 on 22 September 2007, 20:01:19
OK, lets try a step at a time....   :y

From engine cold.....
Unscrew coolant filler cap and insert hose.  Water not running yet.
Put car heater on full hot and have heater fan running.
Unscrew drain tap.  Remember it does not need to be fully removed, only unscrew far enough so that you get a reasonable stream, leaving the red plastic bit still on the radiator.
Start hosepipe running so that input from hose equals output from drain.  You know its correct if the water level stays about the same in the header tank.
Start the engine.
Remember you are adding cold water to a cold engine that does not really get the chance to warm up properly as you are always substituting cold water in for the hot draining out.
Leave it running for about 20 minutes (should be enough) but ensure that it does not overheat by regularly checking the temp guage.  It might need longer.  When the water runs as clear as a clear thing, all should be good.
Switch off engine, switch off hose, leave drain tap running until it stops.
Close drain tap.
Let engine cool.
Add 5.5 litres neat red coolant.  Top up with cold water.
Still with heater on hot, with heater fan on and expansion cap OFF, start engine.  Regularly squeeze the large radiator hose (2" diam approx) beside battery to expell air into header tank.  Keep an eye on lthe water level topping up with cold until engine reaches normal operating temperature.  Replace coolant cap, take it for a short drive to ensure alls OK, then park up at home and leave it overnight.
In the morning check the level again and top it up.  It will have dropped slightly overnight.
Adjust the heater etc and drive as normal with a large smile on your coupon, confident in a job well done......

 ;)

guys, will it be safe if i flush the system tomorrow with the hose as much as i can, probably 8 or 9 times etc etc
and then just leave plain water in there until i go to work on Monday, its only 8 miles there and back
then when i come home, flush it out again a few times, then add the red stuff?

Title: Re: Coolant flush
Post by: hotel21 on 22 September 2007, 20:03:54
We posted at the same time. Leaving water only in the system will be fine for a day or two.  Just don't forget to add the coolant and don't rag the car too hard in the meantime.  The red coolant is antifreeze but also a corrosion inhibitor and water wetter/temp transfer agent as well.
Title: Re: Coolant flush
Post by: TheBoy on 22 September 2007, 20:04:08
Wayne - do it over period of a few days, as I said before.

Now you have done it a few times, you know how easy it is, and how quick to can do it.  So I would suggest draining and refilling with water daily for a week or so.  At this stage, coolant should be fairly clear, maybe slightly brown.  Then after a few days, drain it again, and chuck the 'Red' in.

Please note - if its going to be cold at night, you'll have to chuck the 'Red' in anyway...

Post by: Wayne on 22 September 2007, 20:11:13
reckon i should drain and refill it 3-4 times per day for 1 week?

and making sure i run the engine between each flush?

so really i need to go and spend £25 on 2 big 5 litre tubs of the red stuff
as i will need to add it each night (incase) it gets cold?

this is all becoming more expensive than i imagined

Keep an eye on the weather forecast ;)

I just bought a 20l drum of Red for £24.99 + VAT - advantages of TradeClub ;)


I suspect you are paying for years of poor servicing now.  Blue has a MAXIMUM life of 2 years - your 'at least 5yr old' stuff is going to take lots of flushing :(

i suppose your right

i may get 20 litres aswell

i wonder IF we can have a competition to see who has to have the most flushes?

bet i win!

my car has had regular oil changes every 5000 miles, filters, etc etc
and the coolant has just been drained and refilled, but as far as im aware NEVER flushed like it should have been

i just popped out a minute ago, ran heater at HOT for 25 minutes
will make sure i do this everytime im in the car, damm..its gonna get boiling!
this is the best way to clean the crap out i take it?

Just done the first of todays coolant flushes after doing loads yesterday

does this brown lucky gunk ever go away?
after putting 5 litres in ox the VX red stuff yesterday, when i just emptied it, it was murky dirty orangey brown!

i drained, refilled, then ran engine on hot on the heater for 10 minutes

got the temperature up to 95

how long a time should i leave it to cool down?

gonna try and do this until dark tonight

then a million more times tomorrow!

DAMM THIS BROWN FILTH!!

Title: Re: Coolant flush
Post by: hotel21 on 23 September 2007, 16:54:51
You are doing OK, just take care to relieve the pressure in the system by gentle release of the expansion tank cap before drain.  Take care not to get scalded.  Obviously much better to allow the engine to cool considerably (hour or two?) before adding cold and running/flushing again.   :y

number 2 !!!  ;D ;D

only 80000000 flushes to go

although i have treated my coolant system to Forte already, still lots of brown gunk in there
i cant afford another £16 for anymore, its just too expensive, should i use some WYNNS coolant flush tomorrow?
or is 1 of these flushants good enough just once when doing all this? will i damage anything?

Mate if the car is not overheating, I would personally just flush lots and lots with water, and then refill with 50/50 longlife antifreeze :y

James - i done the flushing with water yesterday about a million times

i added 5 litres of anti-freeze already
came back 2 hours later and the stuff was dirty blueish brown!
so that must mean its still full of crap?
i already done 2 flushes today with 15 - 20 minutes of engine running and heater on MAX
i dont want to buy another 5 litres of the red stuff and then add it, and it turns bluey shitty brown again
this "simple" coolant change is costing me a fortune!
my car isnt overheating, and YES i did follow the Forte instructions, the instructions do NOT tell you nothing, i ran my car for 40 minutes on my drive....  i didnt rate the stuff that well, as i still got gunk coming out
after just finishing number 2 flush, will look in the morning and see what colour it is again, i wont be surprised if its shitty still?
am i doing something wrong?
will i know that the time is right to add the red stuff IF i leave my car for 2-3 hours and come back and the water in the header tank is finally crystal clear like water?

when you coming to check my rocker gaskets James?

PLEASE !!!!!!!!!!!!!!!!!!  :'(

If you ran the engine with the forte in, thats fine, no need to put more chemicals in :)

Just need to keep flushing through with water :)

As we've said, you cannot (easily) fully drain V6, so each time you do it, you are lowering the percentage of the naff stuff, so the more you do it, the more you get out :).  Because you cannot fully drain V6 is why, when garage drains and refills, you are not really getting a proper job.

OKAY MATE

just getting concerned incase i bugger my car up
as to my question in my previous post, whats the answer to finally knowing when its time to add the VX red stuff?
it seems everytime i come back 2 hours later and check the header tank, its murky coloured again
should it be clear after a billion flushes then?
i was thinking, my car is a 1998 so it isnt  new car... can you really get them to run as clear as water and actually see the red stuff staying red?

When you say murky, any signs of oil in it (will be like a light brown creamy mayo)?

Post by: Wayne on 23 September 2007, 18:58:09
none of that stuff mate, the refilled water just seems a bit off colour when u check it after 2 hours
nothing floating around, just very murky, my point is that after i added the red stuff on saturday and came back, you couldnt see any red whatsoever in the coolant tank, it had gone back to a bluey sort of browney colour

It took me a total of 8 flushes to clear mine .... and it was driven for at least 5 miles between flushes .. except for 7-8 which had a 250 mile drive !!

In went the antifreeze after the 8th drain and it still looks a nice slightly orange colour a week later .. :)

It does take a lomg time. I emptied the coolant via the drain and topped back up with hot water each time, ran it for a couple of minutes to top up(ish) the system again & then drained it. I also did a bit of waht Broocie had suggested & ran the engine with the drain tap opened a little but with a hose connected to the hot tap keeping in replenished.

(I really do need to do the same with my Astra - it's had plain water in for the last few weeks  :-[  :-[  :-[ {or is it months?])

Why should it be cold? Hot was used as the water coming out was hot  --- thermal shock & all that! (Been there done that many years ago as I was limping my MkIII from Pompey to Manchester using what ever water I could find as I had a hole in the rad. I managed to crack the block! :'()

It does take a long time if the cooling system has not been flushed aout before, after each flush though the gunk coming out should start to reduce,
I did mine yesterday and it took 4Hrs with filling up running for 10mins or until the thermostat opened and then draining again. I carried on doing this with clean water until all the crude had stoppped coming out.
