Hey Jason, Thanks for the good details, am planning to do this job this week. Question: if I want to take the oil cooler off but leave hoses on can I just crimp the lower to save the coolant and just disconnect cooler from the top{water} do I need to crimp that one also,can't imagine much water pumping out.Thanks for your help.

Bringing back an old thread but mine is now leaking pretty bad on start up so it looks like I will be replacing the seals. A couple of questions first: do I need to drain the oil and coolant? Also is the part number for the seal kit 1036? Thanks in advance.

Paul, I just replaced the Oring and gasket where the bolt goes thru. I drained the oil but did not remove the coolant lines so didn't need to drain the coolant. the Oring # is 90301-61003 and the gasket is #15785-35010. I changed them without taking the cooler out by leaving coolant lines attached and working with a small needle nose pliers and a dental pic,quite easy to do.Both were pretty rotten and with new gaskets it doesn't leak a drop in well over a year now. Hope that helps.

Thanks Mark, I found the seal kit, 3 seals, on Ebay for around $13.

Well I finally got around to doing this today as the weather finally improved enough to not sweat buckets while working. Anyway, I took off the tire and heat shield and what a pain in the butt it was to change those seals especially the large one. I left the cooler attached and trying to get the seal under the tabs with so little room was a major pain. All told it took me about 2 hours from start to finish but thankfully it worked and happy to report, no more leaks. I also left the oil in and only lost about 1/2 a quart at the most.

So I removed the oil cooler and the upper pipe/tube that connects with the smaller u-shaped rubber hose to the engine was full of orange/brown sludge and so is the pipe coming from the engine. I was able to clean out the oil cooler with brake cleaner and compressed air, but what is the best way to clean/clear out the pipe/tube coming from the engine? Pour distilled water down the radiator and hopefully it cleans it out? Any help is appreciated.
