Typical Cooling System Components
- Pressure cap
- Transmission cooler
- Water pump
- Reservoir tank
- Heater core
- Rubber Hoses
Signs of Overheating
- The temperature gauge. If you notice your engine is running hotter than normal, it’s time for an inspection.
- Check to see if any green, orange, or yellow fluid is leaking from under your vehicle. If it is you are probably losing coolant and should get it inspected.
- Squealing noise when engine RPM increases. This could mean a loose belt which would cause poor circulation of the water pump.
What do we inspect?
- Radiator for leaks and debris clogging the fins which reduces cooling performance.
- Coolant for protection level and contamination.
- Pressure test radiator cap.
- Cooling fan operation.
- Fan clutch (if equipped).
- All belts for cracks and deterioration.
- All hoses for leaks, softness or bulging, indicating deterioration from the inside out.
- Check for leaks at thermostat housing, intake manifold, engine heads and freeze plugs.
- Water pump for leaks.
- Reservoir tank for leaks.
- Heater core for leaks.
