The aluminum slantback radiator allows for increased effective cooling surface area. The aluminum core is a crossflow radiator, where cooling fins surround the horizontal tube design. The top and bottom ribs strengthen the assembly. The saw cut in each strengthened rib allows for expansion during temperature changes.

The inlet and outlet tanks are molded with high temperature nylon--reinforced plastic. A high temperature rubber gasket seals the tank flange edge. The tanks are clamped to the core with clinch tabs. The tabs are part of the aluminum header at each end of the core. A plastic serviceable drain cock and rubber seal is used.

The integral transmission oil cooler is housed inside the outlet (RH) tank. The cooler provides the A/T fluid cooling capacity. This maintains a fairly constant fluid temperature under all operating conditions.

The 103 kPa (15 psi) pressure type radiator surge tank fill cap seals the surge tank and raises the boiling point of the coolant to about 128°C (262°F) at sea level. The pressure cap causes the system to operate at higher-than-atmospheric pressure. The pressure valve opens at about 103 kPa (15 psi) in order to relieve excess pressure in the cooling system. Vapor is then discharged. The cap pressure rating is embossed on the cap.

The cooling system is filled through the plastic radiator surge tank. The tank is mounted at a point higher than all other coolant passages. This provides an air bleed for the system. The radiator surge tank coolant level should be maintained up to the full cold marking.
