Hey all... Recently did this really annoying and painful job and decided we might as well get a DIY out of it

If you have oil seepage or leaking near your passenger side wheel area, the oil cooler gasket could be the culprit. It's relatively simple in terms of parts, but getting to it and replacing the oil cooler hoses can be a real pain.

Tools:
Socket wrench - 10, 12 mm sockets, extensions
Phillips screwdrivers
Pliers, vice grips, anything small that clamps!

Parts:
19422-PH7-010 HOSE, IN. OIL COOLER
19423-PH7-010 HOSE, OIL COOLER OUTLET
91318-PY3-000 GASKET, OIL PUMP

Here are the replacement parts (not the tidiest of work areas!)


1. To begin, drain the oil and coolant from the radiator and remove the oil filter.

2. Remove the bumper and under engine splashguard (or at least enough to get clear access to the oil cooler.

Here's my dirty, beat to hell Legend after a 650 mile trip from Chicago to Kansas City with everything removed and ready for the oil cooler job.


First light on the oil cooler since 1989


3. Remove the plug cover circled in red. Mine was completely fossilized and half broke off when i took it off. When I put it back together I just used high temp silicon gasket maker to mate the pieces back together. Next, remove the single wire attached to the oil pressure sensor with a small Phillips screwdriver.

4. Remove the three long screws (10mm or 12mm) holding the cooler on to the engine. Be prepared for some oil to spill out as you pull the cooler from the engine.

5. Using vice grips or pliers, push back the clips and remove the two oil cooler hoses on top of the oil cooler (you may need to cut them off if you have corrosion). Also, you may have noticed that you only drained about a gallon or so of the coolant from the radiator... The other gallon or so will come out when you disconnect the coolant hoses. The manual said be prepared for coolant but I didn't really heed that advice and ended up with a nice green river flowing out the garage! Finally you can remove the oil cooler itself and the figure-8 gasket.

Here it is after the oil cooler was removed:


6. Disconnect inlet/oulet hoses. This is the painful bit... again it may be a lot easier to just cut off the hoses.

Below the circled wire plugs is where the outlet hose connects to the outlet pipe. Vise grips saved me on this part!


7. Installation is the reverse! I had some corrosion and did my best to smooth things out and remove it w/ a little steel wool and sand paper. You may find a tiny bit of lithium grease goes a long way to helping the new hoses slip on.

WONDERFUL

So glad this has been done, now we just need one for the oil pan and we have just about all oil leaks covered

DIY's like this could eliminate quite a lot of threads from people asking where and how and what if... Great Job.

Are you using new hoses (the old ones have probably expanded too much for the clamps to slide back on)? Check that you haven't deformed the clamps and be sure to use a pair of vice grips on the clamps instead of pliers so you have an extra hand free. It's a PITA job because there's so little room to work with but just keep at it and you'll get it done.
