In addition to JimM's great information, check out
http://www.oilcoolers.com/ , Pacific Oil Cooler Service. Lots of good info
there. If you get to OSH next summer, look them up. You'll be amazed at
how much crud can accumulate in your oil cooler.

I had these guys O/H my Mooneys oil cooler and haven't had any
problems.
