Cooling System - Description

DESCRIPTION




Figure 1 - NATURALLY ASPIRATED ENGINE COOLANT FLOW





The cooling system regulates engine operating temperature. It allows the engine to reach normal operating temperature as quickly as possible, maintains normal operating temperature and prevents overheating.










The cooling system also provides a means of heating the passenger compartment. The cooling system is pressurized and uses a centrifugal water pump to circulate coolant throughout the system. Gas engines use a separate and remotely mounted, ambient pressure coolant recovery bottle using a pressure/vent cap. Diesel engine use a separate and remotely mounted, pressurized coolant tank using a pressure/vent cap.

The cooling system consists:

- Radiator
- Coolant
- Electric Cooling Fan
- Water pump
- Dual Thermostats (Gas Engines)
- Charge air cooler (Turbocharged vehicles only)
- Hoses and clamps
- Transmission oil cooler
- Coolant Recovery system
