Ford oil cooler off a 97 mustang 4.6 2v. Will fit 5.4L and 4.6L engines. I ran synthetic motor oil and learned the hard way older engines will leak oil in places they never leaked oil before. Removed rather than replace it. Easy To Fix: Wash it in a solvent bath, dry it out and put in a new "O-ring. Good as new/used. Offers or trades. Looking for: :One or more 2"inch or 3"inch steel ball bearing, :Working vehicle alternator, any make.
