COOLING SYSTEM ROUTING - 3.7L ENGINE
For cooling system routing refer to. HOSE CLAMPS
The cooling system utilizes spring type hose clamps. If a spring type clamp replacement is necessary, replace with the original Mopar! equipment spring type clamp.
WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL NUMBER 6094. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.
CAUTION: A number or letter is stamped into the tongue (1) of constant tension clamps. If replacement is necessary, use only a original equipment clamp with matching number or letter.
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.
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.
The spring type hose clamp applies constant tension on a hose connection. To remove a spring type hose clamp, only use constant tension clamp pliers designed to compress the hose clamp.
DIAGNOSIS AND TESTING
ON-BOARD DIAGNOSTICS (OBD)
COOLING SYSTEM RELATED DIAGNOSTICS
The powertrain control module (PCM) has been programmed to monitor certain cooling system components:
• If the engine has remained cool for too long a period, such as with a stuck open thermostat, a Diagnostic
Trouble Code (DTC) can be set.
• If an open or shorted condition has developed in the relay circuit controlling the electric radiator fan, a Diagnostic Trouble Code (DTC) can be set.
If the problem is sensed in a monitored circuit often enough to indicate an actual problem, a DTC is stored. The DTC will be stored in the PCM memory for eventual display to the service technician. (Refer to 25 - EMISSIONS CONTROL - DESCRIPTION).
ACCESSING DIAGNOSTIC TROUBLE CODES
To read DTC’s and to obtain cooling system data (Refer to 25 - EMISSIONS CONTROL - DESCRIPTION).
ERASING TROUBLE CODES
After the problem has been repaired, use the DRB scan tool to erase a DTC. Refer to the appropriate Powertrain Diagnostic Procedures service information for operation of the DRB scan tool.
ENGINE COOLING SYSTEM OVERHEATING
Establish what driving conditions caused the complaint. Abnormal loads on the cooling system such as the following may be the cause:
• PROLONGED IDLE
