Radiator: Description and Operation

The radiator is a crossflow, tube type that has an aluminum core (1) with plastic side tanks.

The fan shrouds direct air flow through the radiator core and the shrouds also serve as a fan guard.

The right side end tank (4) houses the transmission oil cooler (3) that has inlet and outlet fittings (5) for transmission fluid circulation.

The left side end tank (9) houses an optional engine oil cooler (11) with inlet and outlet fittings (8) for engine oil circulation.

Vehicle equipped with A/C use a radiator with extra cooling capacity for greater cooling demands.

The radiator uses a plastic drain cock (7). This is on the bottom, left hand side end tank.

The crossflow radiator uses a pressure-vent filler cap to allow a buildup of 103 kPa (15 psi) in the cooling system. The cap allows the system to operate at a higher than atmospheric pressure. This pressure raises the boiling point of the coolant to about 127°C (262°F) at sea level, which increases the cooling efficiency of the radiator.
