Radiator Core and Inlet and Outlet Tanks

A cross-flow aluminum radiator core is used on all models. Plastic inlet and outlet tanks are located on either side of the cross-flow radiator core. All radiators used with automatic transmissions have transmission oil cooler inlet and outlet fittings for transmission fluid circulation. Vehicles with manual transmissions use radiators without transmission oil coolers.

Identify an aluminum-plastic radiator by a note on the outlet tank, 127 mm (5 in) below the filler neck, which reads: Important -- For Repair See Harrison Service Manual. This section as well as the Harrison Service Manual describes the service procedures for the aluminum-plastic radiator.

Heater Core

Hot coolant from the engines cooling system is directed through the heater core. The coolant is returned to the cooling system when the engine is running. The heater core transfers heat from the coolant to the air passing through the heater core fins. In order to prevent flow of coolant through the heater core, a hot water shut off valve is not included in the heater system.
