Section 1 (Engine Cooling System): Description
WARNING: This page is about a different car, the 1988 Toyota Celica and 1987 Toyota Celica. However, it is still accessible from the selected car via links, so may be relevant.
The basic liquid cooling system consists of a radiator, water pump, thermostat, cooling fan, pressure cap, heater (if equipped), and various connecting hoses and cooling passages in the block and cylinder head. In addition, many cars use a fan clutch (incorporating a thermostatic control) or flexible fan blade. These reduce noise and power requirements at higher engine speeds.
Some models may use a thermostatic vacuum switch to advance ignition timing in the event of overheating. Most models use a coolant recovery system to prevent loss of anti-freeze.
