evening chaps,little bit of advice please...this afternoon while taking the family out,the displays chirps up a coolant low message..upon getting home it was indeed low,so i 50/50 and filled it up again,approx 1-pint(ish).now this is all ok ,just that approx 4 weeks ago ,coolant low message was on the display ,and again i filled it up, yep you guessed it approx a pint,so in about 4/5 weeks and roughly 650 750 miles it has used 2 pints of coolant,now, the acid question is this fairly normal(cough!) or should i be starting to worry about something?no gunk in the header tank,no gunge around the oild filler cap etc,and as far as im aware no leaking hoses etc.anyone got a rough idea of what it could be?
oh yes i havent done a coolant flush yet,could that be a prob?
-
Check the heater bypass valve at the back of the engine
reglar culprit..
-
Check HBV at back of engine.
If no visible leak anywhere, you may have the usual oil-cooler problem...
-
JamesV6CDX you'r fast mate... ;D
-
as said, check hbv first... ...then move on to coolant bridge....
-
fingers crossed its the hbv....so my next question any guides to changing this please..?????

I have to top my coolant up every two weeks or so, although I don't have any visible leaks either. I checked my HBV when I did the rocker gaskets and that was fine.
However, I have noticed some crystals on the front of the radiator even though it's never looks damp, so i suspect it may be a slow leak from that. Worth remembering to check that too.

Must be the season for it!
Im getting through abou 1 litre every 200 or so miles
HBV was damp, so I replaced it, easy, but fiddly, the trick is to find a good way to remove the bloody clips!
I needed to do a coolant flush, least this has done it for me!
Gawd knows where its going, cant find anywhere else damp
No oil in water or vice versa.
Maybe we need a coolant loss party!

What's your radiator like? I took the plastic cover off the top and looked down the middle between the radiator and the air con radiator - it doesn't look damp but there's white crystals building at the side of it.

Dunno tbh, will have a look when I get a chance, time isnt on my side at the moment unfortunately.

'usually' if you have an external leak of coolant you can smell it.....sickly sweet smell
I sincerely hope its not an oil cooler cover erroding like I had.

I had a leak of gas that had a very sickly sweet smell a few months back, but that was the air con gas.

Hi all,
I picked my 1997 2.5 CD Omega up on Fri but didn't use it over the weekend due too work, only been using it daily since Mon and im having to top up my coolant header every 100 miles, no visible signs of leaks. It may be the valve as stated in this post, but how do you access it? That engine looks like its showing you it on the back which isn't accesible from under the hood
Daft question?!?
Cheers,
Iain

Is it contagious? :( Whenever I read of a new problem on here my Megga catches it >:(
Just checked my coolant level and its about half an inch below min >:( No oil on top of water and both dipstick and filler cap are clear. I'll check for leaks at the weekend. :-/
