Title: oil cooler cover
Post by: manolo on 13 April 2011, 10:03:52

Hi
I have coolant leak on oil cooler cover (y26se). Is it possibile to repair cover or better to replace with new cooler and cover
(engine have 240000 km)

You can re-seal the cover, take the plenum off, injection manifold and support plate off. You can remove the top cover, then re-seal it.

Are you sure its the plate and not the coolant bridge or thermostat?

thermostat is new, and it is not coolant bridge leak

Clean it up and re seal it. Unless the cover is damaged. Usually a re seal is enough if the leak is around the edge. However there have been some cases where the cooler cover itself has a hole in the top. A leak there should be obvious though.

Grey goo and crows feet is all covered in the guides section. :y

You'll need 4 dowty washers, the seals for the oil cooler to cover and 8 seals for the banjo bolts that at either end of the oil cooler pipes.

It's personal choice, but in addition to the doughty washers, I like to use new banjo bolts on the coolant bridge, if they're the original ones  :y

I had one exactly the same on Monday, bet it was the rear nut ;)

Yes sometimes the cooler sits too deep in the coolant bath(?) it sits in and the nuts don't reach the threads.

Put the nut on the banjo bolt, then screw the banjo bolt into the cooler and pull the cooler up, then screw the nut on to the thread. You "may" find there is enough thread to catch and do up. That looks a bit too far gone though tbh, but worth a try....? :-/

Seen those threads strip before, its very hit and miss if you get away with it in my experience (and one reason why I am not keen on re-sealing the oil cooler if I dont have a spare one)

Put a wipe of the grey sealant around the rubber seal in the oil cooler to give it a bit of a helping hand in the sealing stakes.

What is it that is destroying the threads? I assume the OP's cooler is the original one and should have been intact? And still the threads are shot?

I wonder this because I once took my previous 2,6 to the dealers for very difficult to locate water leak and they found this exactly the same thing; stripped threads. The cooler had been intact by then and the car had done some 100k miles.

Does anyone have the measures for banjo bolts and dowty washers? I have access to a fair selection of these and would rather take them off the self to have them handy just in case than go to the stelaers  :y

Thing is, probably wasn't the mechanic's fault.

That bit of thread always has a nasty habit of breaking, I've seen it lots and lots.

If even MDTM won't change one without a spare handy, that speaks volumes  :D :y

Not that long, a few hours work?

Plenum off
Inlet Manifold off
Manifold plate
detatch oil cooler pipes **at the filler end (19mm crows foot spanner best)
then the oil cooler itself...
Re-assemble.

I reacon on 2.5-3 hours to do this job all in.

The threads seem to strip due to seizing (corrosion maybe?)
