Section 4.1
Cooling System Overview
The cooling system consists of the following components.
- Water Pump
- Thermostat
- Air-to-Air Intercooler
- Radiator
An OEM supplied radiator is used to dissipate the heat generated by the engine. A water pump is used to circulate the engine coolant. A thermostat is used in the water outlet passage to control coolant flow, providing fast engine warm-up and regulating coolant temperature. Pressurized engine coolant is drawn from the radiator and forced through the oil cooler into the cylinder block.
When the engine is at normal operating temperature, coolant passes from the cylinder block, through the cylinder head, through the thermostat housing and into the upper portion of the radiator. See Figure "Coolant Flow" .
