COOLING SYSTEM
1. GENERAL DESCRIPTION
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions. When the engine is cold, the cooling system cools the engine slowly o
r
not at all. This slow cooling of the engine allows the engine to warm up quickly. The cooling
system includes a radiator and recovery subsystem, cooling fans, a thermostat and housing, a
water pump, and a water pump drive belt. The timing belt drives the water pump.
All
components must function properly for the cooling system to operation. The water pump draws
the coolant from the radiator.
The coolant then circulates through water jackets in the engine block, the intake manifold, and
the cylinder head. When the coolant reaches the operating temperature of the thermostat, the
thermostat opens. The coolant then goes back to the radiator where it cools. This system
directs some coolant through the hoses to the heat core. This provides for heating and
defrosting. The coolant reservoir is connected to the radiator to recover the coolant displaced
by expansion from the high temperatures. The coolant reservoir maintains the correct coolant
level. The cooling system for this vehicle has no radiator cap or filler neck. The coolant is
added to the cooling system through the coolant reservoir.
