This radiator uses an aluminum core with plastic core tanks. The lower core tank houses the automatic transmission oil cooler. The drain cock is located in the lower tank. The drain cock is serviceable.

The core is made of aluminum. The core is a downflow design that uses large tubes. The tubes resist plugging. The core is attached to the tanks by clinched tabs on the core.

The tanks are fastened to the core by clinched tabs that are attached to the sides of the core. Bend back the tabs if you need to remove tanks from the core. Bend back the tabs only enough to remove the tank. Over bending weakens the tabs.

A high temperature rubber gasket seals the mating surface between the core and the tank. Replace the gasket whenever you remove the tank from the core.

The aluminum/plastic radiator uses a two-piece plastic cock and a rubber seal. The drain cock is serviceable.
