Radiator: Description and Operation

Crossflow Radiator:

DESIGN DESCRIPTION
All radiators are the tube and fin type with the tubes arranged for horizontal flow of the coolant with gasoline engines and vertical flow with diesel engines. Two header tanks, one on each end of the radiator, allow uniform distribution of engine coolant to the radiator tubes. The radiator outlet port (lower hose connection) is connected by a hose to the water pump inlet port. The radiator inlet port (upper hose connection) is connected by the hose to the coolant outlet elbow of the engine, allowing coolant circulation through the radiator when the engine thermostat is open.

CORE AND TANK TYPE
The crossflow radiator used with gasoline engines is constructed with a vacuum brazed aluminum core and nylon end tanks. The nylon end tanks are attached to the aluminum core by bending tabs on the core header over the edge of the nylon tank. An O-ring gasket is placed between the nylon tank and the radiator core header to achieve a seal between the tank and the radiator core header. The nylon tanks are a molded one-piece design with the mounting brackets part of each tank.
