engine oil cooler

Summit RacingSummit Racing Verified Purchase

The cooler it's self works as it should and was easy to install. The only issue I have is the plastic mounting hardware. The plastic "nuts" that are to hold the cooler tight to the radiator do not tighten up. Pretty expensive unit when I'll have to come up with my own mounting hardware.

Engine Oil Cooler

This oil cooler fits great right behind the front valance. They give you all parts needed to install the cooler properly. There was one problem when I ordered the oil cooler, which was the different vehicle application that it would fit. My 67' Cougar uses a PH8A oil filter, and my 72' Datsun 620 Pick-up also uses a PH8A oil filter. They might need to check a little closer on what is compatible with different vehicles. ...read more

Flex a lite 3951

Worked as advertised, would have helped to have a little better way to secure the cooler to the condenser but overall happy with the result, if you have headers, fab a heat shield between the hoses and the headers if they come close.
