General Information

PURPOSE
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.

OPERATION
The cooling system also 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 on all engines to circulate coolant throughout the system.

MAXIMUM DUTY OPTION
An optional factory installed maximum duty cooling package is available for some engines on most models. This package will provide additional cooling capacity for vehicles used under extreme conditions Such as trailer towing in high ambient temperatures.
