DESCRIPTION 

DESCRIPTION 

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. A separate and 
remotely mounted, pressurized coolant tank using a pressure/vent cap is used.
