hi guys just noticed that my water res is full of what looks like baileys have checked dip but all ok no oil lost cleaned it out last week but the same today ,stuff is thick light brown i have 2.6 v6 estate 2002 any idea lads only got 47k on clock and full vox history

[Markjay]

It's either head gasket (unlikely), or the oil cooler (very likely...). The oil cooler sits in the block between the cylinder banks under the intake plenum, and is immersed in coolant. If you want to make sure it is NO head gasket, get an MOT garage to stick a gas analyser into the coolant expansion bottle (but not into the liquid) to check for presence of exhaust gases.

thanks is it safe to drive , only do 4 mile a day in week, will get it to vox this week looks like mega bucks repair

Nowhere near as big a job as head gaskets, but still a good few hours work.

I'd avoid driving it unless absolutely necessary, it'll run OK for a while but more chance of overheating as the coolant sludges up with oil, and the longer the run it the more likely you'll have to replace the radiator as you won't be able to get all the oil out.

I would guess it’s around £100 for the parts (retail price) and two hours work, so around £200 in Vx money…

You can get the parts on the cheap (probably £80?) and do it youtrself though.

As for driving, as long as you keep the bottle topped-up and check the oil the engine will not suffer immediate damage, but it is still not recommended – the more you drive like this the more crude you collect in the cooling system, and unless the system is flushed thoroughly you will have overheating problem in the future…

If it make you feel any better, my oil cooler went when the car had around 25k miles... but on the plus side the car was only two years old at the time so it was replaced FOC by Vx under warranty.

thanks mark i have a warranty with the car but its not vox looking at the book it should be covered but you no what warrantys are like mate it do,s not cover external leaks but this is internal so fingers crossed

2 hours??  

You been on the beer already??

I doubt even Mark could do it in 2 hours!

For us mere mortals 6 hours  would be nearer the mark!

I thought the quality of the oil cooler was much improved in later models? Apparently not!

No worries, I wouldn’t do it in 6 days…  

iirc that’s what the garage estimated the work, but I’ll check again (I don't have an invoice as it was FOC but I photocopied the garage’s job-sheet at the time)

[Markjay]

Apparently not…

at 2 years old and 25k mine went for no apparent reason... and it’s a 2001 car so should have the latest cooler etc…

[Markjay]

You were right LB...

That's what the job sheet says:

------------------------------------------------------------------------------

J635100 Cooling System - Check for Leaks - 0.3h

J608700 Coolant Bridge - Remove and Reinstall (Heating Hose Adapter) - 1.4h

J315600 Replace Oil Cooler / Heat Exchanger TC: 42 Leaks - 3.2h

J31500001 For vehicles with lower engine compartment cover - 0.2h

J307000 Cylinder Head Cover – Remove and Re-install – Petrol Engine - both cylinder heads - 2.2h

------------------------------------------------------------------------------

The last line is rocker cover gaskets (2.2h), so not strickly required for the oil cooler job?

[Markjay]

Incidentally Deano, the parts you'll need are:

That depends... the job numbers and times they quoted in the jib-sheet are from TIS2000, and the way I read it, the oil cooler job is 3.2h plus 0.2h for the engine lower cover removal (which took me 3 minutes when I did this a couple of months ago...?), not sure why they added the coolant bridge removal - surely this is included in the oil cooler change job?  

They may have been other things wrong which they sorted under warranty, they don't actually tell you... for example if I didn't insist on photocopying the job-sheet I would not have known that they changed the rocker cover gaskets - they didn't actually say that to me. Not that I mind they did it, but the point is that the 7.3h was probably more then what is needed just the oil cooler job.

same job and processes - just remember that the pics relate to a vectra   and some ositionings are diffrent ( ie the engine is in wrong way   )

Deano if you need any help on this one ask away...

[deano]

thanks for all your help lads but going to leave it to the experts as every time i do a job i seem to have lots of stuff left i will keep you all informed .

I've noticed the left over bits when working on the car on several occasions my theory is that some sort of weirdo wanders around looking for people working on their cars and when youve got your head under the bonnet he throws an assortment of different car bits in amongst yours just to confuse the hell out of you!

[Markjay]

The left-over bits is like a house of cards – you can always remove one card at random and the house will not collapse, but if you keep doing it then eventually it will..  

[Markjay]

And Deano – I can se how you feel about left-over bits, but think for a moment that the garage does not end-up with left over bits. Incidentally, are all the dust caps in p-lace on the plenum of your V6? Last time Vx changed the cambelt the car was returned minus two dust caps, of course I made them order new dust caps for me FOC!

Its a 3 hour job.....plus flushing....
