I have had an oil cooler let go and it never daused any H/G problems. Im sure plenty of others will say the same.
If the car was driven as normal for a long period of time it would undoubtedly overheat regularily which could cause H/G trouble, but if youve been reasonably sensible I dont think it will cause the gaskets to blow imo.

I think poster was trying to suggest neglect would be cause rather than oil cooler itself. Because for the cooler to fail, it has to have had very poor coolant maintenance, which is also a main cause of HG failure.

That's the implication, but not a realistic one, I believe this is a 2.6 from previous posts?

So not a 98.

We should consider that poor maintenance can give a very dirty coolant bottle, and not have a failed oil cooler!  Suggest a pic posted to confirm...?

Too late Chris, I've already bought all the parts and am just about to go outside and get started on the job.

I really appriciate your advice, and I don't want this to be taken the wrong way, (no dissrespect intended  ), but I've seen plenty of dirty coolant systems in the past. But this one, oh boy, it's really, really bad, hence why I am convinced that I have oil cooler problems.

I poured fresh bright pink coolant in, ran the engine for five minutes and it had turned poo brown.


Anyway, time to get my hands dirty again. I'll report back later when I happen upon the inevitable problems and foul-up's on my part.

No problem at all, as long as your certain. Got yourself a 19mm crows foot?

[V6 CDX-er]

Yep. went to Machine Mart earlier and got myself a set, 10mm to 19mm for £14.

As luck would have it I missed the VAT free weekend by........



one day   

[feeutfo]

At least you have a branch near you. Easy with crows foot mate, steady as she goes and all will be well. You can put that multi ram connector on properly this time.

Oil drained, oil filter off, and here's a sample of some collant that I've just drained from the rad.

This time yesterday this was bright pink, mixed 50/50 with water. Since then the car has covered maybe 100 metres

The coolant was drained directly into the coffee jar, and the coffee jar was clean and dry prior to drainage.




What do you think?

.... and here's a sample of some collant that I've just drained from the rad. .....

yuk!  :-? :-?

[tunnie]

i've seen a lot worse, seen coolant look like hot chocolate!

[Andy H]

And that's pretty dam dirty 

Having an old Landie that I use for off-roading, I'm pretty used to coolant systems being minging and filthy, but on the Omega it really is something else.

As I'm running short of time getting it back on the road I've just topped it up with fresh coolant which will have to do for the next couple of weeks, but TBH I don't think that flushing the rad, header tank and heater matrix is going to shift much of the grime.

So, a couple of questions. On Omegas with air-con, oil coolers and god knows what else plumbed into the rad, does everything need to be dissconnected before flushing the rad, or just the top and bottom hose?

Also are there any decent cleaning agents that can be used to shift some of this gunk, or are they all snake oils?

Many thanks 

I was told that 'Truck Wash' (probably from Machine Mart) was used to flush the cooling system in my 2.6 when the oil cooler was changed just before I bought it.

It seems to have done the job.

once you've fixed the cooler, run the engine with a low suds biological washing powder in it .... mix the solution in a bucket first !!  Numerous applications eventually cleaned the one I did for a mate ... we were doing it 3 times a night for a week..... run it up to temp with the heater on max chat, leave for 5 minutes, switch off and allow to settle for an hour, drain, repeat.

Well, Entwood has had oil cooler failure, and seems to agree.

Was expecting more lumpy oil deposits and signs of Mayo. That just looks dirty to me. Any oil settled on the surface?

When the coolant was changed how much came out/went back in? Could there have been some old coolant in the system to contaminate the new stuff and give that colour?

Hi

Sorry I know this is a little off topic but what are "Banjo Bolts"?

  :-/

 
Bolts used to fit the oil cooler

If I might just add the word "pipes".  ie "bolts used to fit the oil cooler pipes"

If that coolant has a pretty thin consistency, I am not convinced the oil cooler was the cause of that!

Oil cooler will cause sludge - not discolouration on it's own.

I'd have been inclined to do lots of flushing and then monitor, before condemning the cooler, in the abscence of sludge.
