Cooling System: Description and Operation

DESCRIPTION





The cooling system is designed to maintain engine temperature at an efficient level during all engine operating conditions.
The components of the cooling system are:
- A heavy duty radiator
- Cooling fan (mechanical)
- Thermal viscous fan drive
- Fan shroud
- Radiator pressure cap
- Thermostat
- Coolant reserve/overflow system
- Automatic transmission oil cooler (internal to radiator)
- Coolant
- Water pump
- Coolant hoses and clamps

HOSE CLAMPS
The cooling system utilizes both worm drive and spring type hose clamps. If a spring type clamp replacement is necessary, replace with the original Mopar(R) equipment spring type clamp.





CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only a original equipment clamps with matching number or letter.

The worm type hose clamp uses a specified torque value to maintain proper tension on a hose connection.





The spring type hose clamp applies constant tension on a hose connection. To remove a spring type hose clamp, use Special Tool 6094 or equivalent, constant tension clamp pliers to compress the hose clamp.

COOLING SYSTEM REQUIREMENTS
To maintain the performance level of the heating-air conditioning system, the engine cooling system must be properly maintained. The use of a bug screen is not recommended. Any obstructions in front of the radiator or condenser will reduce the performance of the air conditioning and engine cooling systems.

The engine cooling system includes the heater core and the heater hoses for more information before the opening of, or attempting any service to the engine cooling system.
