2017 Ram v-6 going in Wednesday for the infamous oil cooler replacement. Half of the OEM part is plastic. It sits directly on top of the hot engine. It's under the plastic intake manifold, which requires a $50.00 gasket kit. Have to remove the manifold to replace 3 spark plugs any way so going to change them out too.
At least new Dorman part is all aluminum. I thought about doing it, but there is oil, antifreeze, and open manifold ports. About 3 to 4 hours labor minimum.
