Engine Cooling System Inspection
WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
NEVER spray water on a hot radiator. The resulting steam could cause personal injury.
NOTE:
Compressed air or water can be used to clean the radiator fins. Do not exceed 138 kPa (20 psi). Pressure over 138 kPa (20 psi) will damage the radiator.
Inspect the hoses and replace if they are cracked, swollen or deteriorated.
Inspect all pipes, fittings and clamps; replace as needed.
IMPORTANT:
The radiator and A/C condenser should be kept clean for proper system performance. Cleaning is recommended at least once a year.
Inspect the front surface of the radiator and A/C condenser. Insects, leaves, debris, etc. can affect the performance of the radiator and A/C condenser.
If the front surface of either or both of these components is found to be in need of cleaning, the unwanted material can be removed by performing the following:
- Ensure that the engine is off and cool.
- Blow compressed air through the radiator from the rear surface of the radiator toward the front of the vehicle.
- If compressed air is not available, use a water hose to force water through the radiator from the rear surface of the radiator toward the front of the vehicle.
To help ensure proper cooling system pressure performance, a pressure test of the cooling system and pressure cap is recommended at least once a year.
If their is a loss of coolant, refer to Loss of Coolant in Engine Cooling.
