The supercharger cooling system is operationally independent of the engine cooling system, but it has a connection to the radiator upper hose. The connection with the engine cooling system accommodates thermal expansion and retraction of the coolant in the supercharger cooling system. In addition, the connection enables the filling and draining of the supercharger cooling system.
For additional engine cooling Diagnosis and Testing information, REFER to: ENGINE COOLING

| SYMPTOM |
POSSIBLE CAUSES |
ACTION |
| Coolant loss |
- Hoses
- Hose connections
- Radiator
- Coolant pump
- Heater core
- Gaskets
- Engine casting cracks
- Cylinder block core plugs
- Thermostat
- Charge air coolant circuit leaks
- Charge air radiator(s)
|
- Complete a visual inspection. If there are no obvious leaks, complete a cooling system pressure test. Rectify any leaks as necessary
|
| Engine overheating |
- Low/Contaminated coolant
- Thermostat
- Viscous fan
- Engine Coolant Temperature (ECT) sensor
- Restricted air flow over the radiator
|
- Check the coolant level and condition
- Complete a cooling system pressure test. Rectify any leaks as necessary
- Check the thermostat and rectify as necessary
- Check the viscous fan operation, make sure the viscous fan rotates freely
- Check for obstructions to the air flow over the radiator. Rectify as necessary
- Check Active grille operation (If installed)
|
| Engine not reaching normal temperature |
- Thermostat
- Viscous fan
- Thermostat
- Electric fan
- Fan speed module
|
- Check the thermostat operation
- Check the viscous fan operation, make sure the viscous fan is not seized. Rectify as necessary
