    Hey tmkktm, did you change your oil cooler yet? If so, was it difficult and how long did it take you?

    Re: oil cooler change NOW!!!!!!!!

    On an Omega, its takes me 3 hours.....interestingly, we see these fail quite rarely, maybe you guys use a different antifreeze/coolant change schedule to us (it must be changed every 2 years for a 0:50 antifreeze mix or the cooler can corrode).

    The actual part was updated in design in appox 1995 to a stainless steel one, it would then appear to have been changed again to a heavier pattern item in approx 1998.

    As for design....note, these power plants are assembled in the UK (Liverpool - Ellsmere Port) but, not designed there, the design is german and the failure is a design fault!

    I seem to think we have a maintenance guide for this (plus many oterh useful bits) on our Vaux Omega site at

    Arrow Re: oil cooler change NOW!!!!!!!!

    Ok, I took it apart- contourbs was right- it took me just about 2-3 hours to get to it, but mostly because I didn't have the right sockets- I needed a 24 and a 30, which I had to buy, otherwise it would've been faster. I will post some pictures- the thing looks nasty!!! Strange thing was though, when I drained the water from the radiator, it didn't have any oil in it- up to the thermostat, no oil in water; after cooler- everything messy. So I think the radiator would be fine, the thermostat probably could be changed(although not sure how to take it out!!!- took the 2 bolts out and pulled, but nothing!). The HCV seems fine, because the water leak I was talking about was from a different hose, the one that goes to the top of the intake and splits- I'll show that in the pictures as well. So I think that hose was messed up because of the oil, instead of it messing up the plastic upper part on the radiator, which contourbs mentioned, which is actually better. Current problems:-)-1st don't know which would be the best way to clean the system and what should I use to clean it and 2nd I so wish the damn part was cheaper- so don't want to spend $200 even $150 bucks on it- for m... sake a transmission costs $200- so expensive for a tiny radiator!!! I'll post the pictures once I donwload them.

    Re: oil cooler change NOW!!!!!!!!

    If you catch it early then the rad will be fine.

    One method we use for flushing the mayo from the coolant system is to run the car for 20 or so miles with a cup full of water soluable de-greaser in it.

    Then flush through with water well a few times and all shoudl be good.

    As an additional pointer, dont bend the oil pipes that feed the cooler, it makes the re-fit pretty tough, its much easier to remove the oil filter/housing and using a 19mm crows foot spanner, remove the pipes from the block. If you do bend the pipes it can result in oil leaks from the block end because moving and flexing these joints loosens them plus they are a swine to re-fit.

    I pay approx £80 inc tax (about $150 which includes the 17.5% Tax) for the cooler which includes a new plate, 2 bolts and 2 rubber seals plus another £7 ($13) for the grey sealent (works brilliantly on the stat to block joint, much better than the original seal), £4 ($7) for the 4 coolant bridge doughty seals and £2 ($3.5) for the 4 metal oil pipe to cooler washers.

    I note somebody asked about stat removal, to do this you need to pull the bridge pipe out before unbolting the stat. This pipe is held be a single torx bolt on the 2-4-6 head near the power steering reservoir. It can be a swine to remove (its actualy easier to use a 10mm open ended spanner, we refer to it as the b-stard bolt!). Then pull the bridge pipe out (wiggle it whilst applying some elverage). Now the stat can be removed, when re-fitting apply some grease to the rubber seals on the end of the bridge pipe to aid re-fitting.

    Not ideal as you are likely to get 300+miles per tank and the lack of antifreeze means there will be no corrosion inhibitors in the system.

    These units need a 50:50 antifreze mix changed idealy every 2 years.....if you do this you will not get oil cooler failure in the first place.

    Re: oil cooler change NOW!!!!!!!!

    Contourbs, the current exchange rate from American Greenbacks to Her Majesty's pound is well, let's put it this way, one pound would cost about $1.39 American or so. Parts people get us all over the globe. It's still about 200 bucks. I'm gonna have to bite the bullet and buy one tomorrow. I'll have to take some of my Christmas cash and spend it on the CAT. I'll let you all know how much it cost. P.S. If i'm wrong on the exchange rate, please, someone jump in and correct me...thanks.

    Re: oil cooler change NOW!!!!!!!!

    It's still only $142 for brand new, which is pretty good. I tried to win one on E-bay the other day, but somebody bid $180 for it. Sorry about the pictures, I'll post them as soon as I can, I've been so bisy with work right before the holidays! I found one used oil cooler from a wrecked 2000 Catera- $95 and was told it was in a good condition- the car had only 6,000 miles on it when it was hit in the rear. I think I'm going to buy it. What do you guys think?
