Cooling System
The cooling system's function is to maintain an efficient engine operating temperature during all engine speeds and operating conditions. The cooling system is designed to remove approximately one-third of the heat produced by the burning of the air-fuel mixture. When the engine is cold, the coolant does not flow to the radiator until the thermostat opens. This allows the engine to warm quickly.
NOTE:
See arrows for coolant flow order. Notice the port between cylinder head and thermostat housing, as well as the port between cylinder block and water pump.
The cooling system consists of the following components:
- Throttle Body (1)
- Heater (2)
- Surge Tank (3)
- Engine Coolant Thermostat Housing (4)
- Radiator (5)
- Cooling Fan (6)
- Engine Oil Cooler Housing (7)
- Water Pump (8)
- Cylinder Head/Cylinder Block (9)
