dredded oil cooler
11. Aug 2006 at 09:43

Well it had to happen sooner or later, Iv'e got the dredded oil cooler breakdown and gunge in the cooling system of my V6 Omega. Could one of you lads tell me what size of torx sockets and torx keys I need to carry out this repair?
I'm one of the old school still messing about with spanners and box sets. I need to buy these tools as my toolbox just doesnt have any.

Most common ones you will use will be E10 E12 E14, but a torx set will cover all bases

It does require a few sockets.....27mm amd 30mm ring a bell (its been a few months and having the sizes to hand you dont tend to remember them).

The rest is E10/12 etc torx.

Not to hard a job to be honest, I would strongly recommend removing the oil filter/fiter housing and undoing the bottom oil cooler pipe unions.

Dont foregt that you will get water in the oil to so it will need changing.

Aug 2006 at 14:44 next problem, I have the inlet trumpets loose but cant seem to get them out between the two camshaft housings! is there a knack that i'm missing? ive followed the haynes manual and info gleaned from this site but there just isnt the room to manouvre the trumpets out without taking one of the cylinder heads off.

Aug 2006 at 14:45 You need to lean them over to the right by about 20-30deg and wiggle them, if still stuck slide them back and forth until they base of the trumpets line up with some cut outs in the head casting and they pop out....

Halfords 3/8" set doesn't cover the crank shaft pulley bolt! Huh

I found this on a Sunday afternoon when everywhere else was shut! Sad

I did the same thing doing the cam belt on that, so had to & borrow a Torx set from the same bloke ... again!

Aug 2006 at 17:19 and the next problem, the large nuts that hold the oil cooler to its plate will not shift, even with a 1 mtre long break bar. No wonder the garage wanted £600 to do it!. thats enough for the day, time to put my feet up. Who said when you retire at 65 youll have loads of time on your hands? I'm busier now than when I was at work.

Aug 2006 at 18:04 You could just remove the oil cooler still attached to the plate, the new oil cooler kits come with new plates.

Aug 2006 at 18:38 As a bit of a tip.....the oil cooler kit code is: 93176626 It might not appear on EPC but is a recognised Vaux code so can be ordered and costs 81+Vat retail. It includes the cooler, plate and rubber O rings. You will then also need the coolant bridge seals and grey selalent (fits into a mastic gun)
