Cooling System - Description

DESCRIPTION




Figure 1 - Engine Cooling System Flow - 3.7L/4.7L





The 3.7L/4.7L engine cooling system consists of :

- LH Cylinder Head (1)
- Bleed (2)
- Thermostat location (3)
- RH Cylinder Head (4)
- RH Bank Cyl. Block (5)
- LH Bank Cyl. Block (6)
- Coolant Temp Sensor (7)
- From Heater Core (8)
- To Heater Core (9)

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




Figure 2 - 5.7L Engine Coolant System Flow





The 5.7L engine cooling system consists of :

- LH Cylinder Head (1)
- To Radiator (2)
- From Radiator (3)
- To RH Cylinder Head (4)

The cooling system provides a means of heating the passenger compartment and cooling the automatic transmission fluid (if equipped). The cooling system is pressurized and uses a centrifugal water pump to circulate coolant through the system. The coolant recovery/reserve system utilizes an ambient overflow bottle.
