Engine Oil Cooler Recommendation For 1990 GMC Pickup Truck With 4.3 Engine  


I need an engine oil cooler set, that will fit the filter housing of my resto-modded 1990 gmc 4.3 liter engine, standard transmission 5speed. It uses a PH3980 Fram number filter size if that helps.


Expert Reply:

I did some research and found the thread diameter for the Fram oil filter PH3980 is 18 mm x 1.5 mm.

The Derale Engine Oil Cooler, part # D15502 has multiple sleeve nuts and that is one of the thread sizes it is designed to fit so this will work great for you.
