The cooling system of the 2007 Dodge Nitro regulates engine operating temperature, allowing the engine to reach its normal operating temperature quickly and preventing overheating. The system is pressurized and uses a centrifugal water pump to circulate coolant throughout the system.
Cooling System Components
The cooling system consists of various components, including the charge air cooler, two-speed electric cooling fan, engine-driven fan with viscous clutch, aluminum-core radiator, combined coolant recover container/washer reservoir, and thermostat.
Error Messages and Diagnosis
The Powertrain Control Module (PCM) monitors certain cooling system components and can set a Diagnostic Trouble Code (DTC) if an issue is detected. The PCM can also store the DTC for display to the service technician.
To diagnose and troubleshoot cooling system issues, the manual provides guidelines for flow checks, preliminary checks, and basic diagnostics. It also includes charts and procedures for troubleshooting specific issues, such as overheating and error messages.
