Help with '90 S4 Oil Cooler Lines
#32
don't have the part number, but here are specs from post #4. sure you can find at local hardware or auto parts store
the cap screw has a washer attatched and is 26 mm to the head with 21mm of thread, overall about 34mm including the allen head

I just replaced my oil cooler on the 93 GTS and thought I'd add a couple pictures to this thread in case anyone searched on it later. An embarrassingly easy job - but kind of messy due to oil spilling when you first disconnect the lines.
Earlier in this thread you'll see a post from Roger about having a supplier providing rebuilt coolers. He said he no longer uses them; so, our only option is to buy a new one or try taking it to a radiator shop for repair. If you think a radiator is expensive, wait 'til you buy one of these. Just another reason to make sure ride height is correct.
I smeared a little oil on the O-rings before I put them in place and so far no leaks. But, for peace of mind, if I had to do it again I would've put a little drei-bond, honda-bond, etc. on the rings.

I have one with a leak sitting on the shelf. Has anybody dissected one of them?

From professional experience, dissection is typically a one way street. If the goal is to have it repaired successfully, contact the folks at Pacific:

Speaking of trashed/damaged oil coolers...if anyone has one and are willing to drill out the rivets I need a few of the belly pan hooks. My cooler is fine, but a few hooks are missing. Let me know if you can help!

Roger offered it as a service, but it cost more than my cost on a new cooler, back then.

They fixed a stripped mounting hole on the cooler on my GTS and did an ultrasonic cleaning for $150 back in 2010. Not sure what a welding repair would cost.
