This document provides comprehensive service procedures for the cooling system components found in Chrysler vehicles equipped with 4.0L and 4.7L engines. It details the general information regarding system operation, including descriptions of accessory drive belts, radiators, water pumps, thermostats, and viscous fan drives specific to these engine models.
The cooling system regulates engine operating temperature, allows the engine to reach normal operating temperature quickly, maintains that temperature, prevents overheating, and provides heating for the passenger compartment and cooling for automatic transmission fluid if equipped.
The antifreeze concentration must always be a minimum of 44 percent year-round in all climates.
Connect the power cord to a grounded 110-120 volt AC electrical outlet with a grounded, three wire extension cord.
