Brief Description: Installed Steel Fittings in Oil Cooler
I screwed in the steel fittings, instead of the aluminum fittings, into the oil cooler. Anti-seize was applied to the threads. Pacific Oil Coolers (oilcoolers.com) has a good web site indicating that the fittings should be steel instead of aluminum. AN970-3 washers were marked for trimming. These washers will be inserted next to the oil cooler flanges with the aluminum tubes between the flanges and washers.
