GENERAL DESCRIPTION
The cooling system consists of the radiator cap, radiator,
reservoir, hoses, water pump, cooling fan, pellet-type
thermostat and suitable passages for water circulation
through the engine.
RADIATOR
A cross-flow radiator is used on all models. Tanks in this
type radiator are located to the right and left of the core,
instead of above and below (Fig. 6B-1).
Radiators used with automatic transmissions except
some H Series have oil coolers built into the right hand tank
with inlet and outlet fittings for transmission fluid circulation.
Synchromesh-equipped cars utilized radiators without oil
coolers. Vehicles equipped with air conditioning use a
radiator with extra cooling capacity for greater cooling
demands.
RADIATOR CAP
A pressure-vent cap is used on the cross-flow radiator
to allow a build-up of 15 psi in the cooling system. This
pressure raises the boiling point of coolant to approximately
258°F. (125°C.) at sea level.
Do not remove radiator cap to check engine
coolant level; check coolant visually a t the see-
through coolant reservoir. Coolant should be added
only to the reservoir.
