When most drivers see the temperature light come on in their cars, their first assumption is radiator troubles. While some problems in the radiator will cause the temperature gauge to light up, you should know that water pump failure can as well. If your car's water pump fails, the engine could run hot and cause expensive, sometimes irreversible damage. Find out what kinds of problems can cause your car's engine to run too hot.
The Role Of Your Car's Water Pump
The water pump in your car is responsible for moving water and coolant. Without a smooth running water pump, your car's engine will run hot. In some cases, the engine that was too hot for too long can end up with expensive repairs. Some signs that your water pump may be about to malfunction include:
- Temperature gauge lights up and does not go off.
- Water pump belts squeal loudly sometimes, a sign they need to be replaced.
- A grinding, guttural noise could signify the bearings are out in your water pump. These sounds can also mean the impeller is compromised and not working as well.
Malfunctioning Thermometers And Your Car's Radiator
The thermostat controlling the temperature of your car's engine is a vital component for effective cooling to take place. If the thermostat malfunctions, your engine could suffer overheating issues like a blown head gasket. The radiator that is boiling over is more than likely doing so due to a failed thermostat issue.
Overheating Can be Caused By Coolant Leaks
The puddle of engine coolant you find under your car could mean a leak in the head or block of the engine. Bear in mind that a cracked block means expensive repairs. If you find engine coolant leaking from your car's engine, it is vital you locate the source of the leak and make repairs. Common engine coolant leaks are:
- If your radiator cap does not make a tight fit, you may need to replace it or the seal inside it. Once the fluid in your radiator gets too hot, it will find its way out around a loose radiator cap. The cost of cap replacement is a lot cheaper than replacing an engine due to a cracked block or blown heads.
- Overfill reservoirs are common locations for engine coolant leaks.
- Old or dry rotting hoses can be the cause of coolant leaks. Always check your radiator hoses on a regular basis for learning when it is time to replace them.
Keeping up with regular maintenance checks on your car can be the best way to avoid expensive repairs later on. If you do not have the time or are unable to do maintenance and inspection checks on your car, dropping it by and leaving it with a qualified mechanic is recommended.
