Im going to replace my (#9, 15194579) Oil Cooler Hose Assembly. Do I replace the (#11, 15759293) Oil Cooler Hose Seal and the (#6, 25013767) Oil Filter Bypass Valve too? If so, is there an oil seal between the hose assembly and the block? if so can someone tell the part number? any tips to an easy change?..Thank you in advance...Tony

 

I didn't replace #6 but replaced both hoses. I bought from AA though. They lasted about a year before they started to leak again. Then I did the hose mod and still good today. New gaskets came with the hoses I bought from AA (Dorman brand).

 

I will be doing the hose mod..any suggestions on what type and size of hose to use?

 

I just did mine and used the same hose yhat came with it. Bought new and modded that one

 

I will be using an old hose from the pull a part and doing the hose mod..but i still need the info on the seals and valve.

 

Best thing I can say is if your doing this on a budget just take a good look at the old ones. maybe you can get by.

 

not trying to do it on a budget..trying to do it right the first time....still need answer to the seal and valve question....

 

There are three valves. Two in the remote oil filter adapter and one in the block. Two are the same and the other is different pressure. Don't mix them up or put the wrong ones in. One in the remote adapter is a real pain. Is there a reason why you think they are bad or contaminated? I replaced all three of mine due to metal in oil. If you haven't had a bearing problem I would leave them alone. Seals on both ends of the main oil cooler hose are the same and are available from Doorman.
