Your vehicle's cooling system plays a vital role in regulating engine temperature and preventing excessive heat buildup. When a cooling system component stops working properly, your engine may struggle to maintain a safe operating temperature. Ignoring an overheating problem can result in serious engine damage and expensive repairs. Knowing some of the most common cooling system issues can help you recognize warning signs and seek professional service before a minor problem becomes more severe. At Gab’s Auto Repair, we provide expert cooling system repair in the greater Phoenix area. Here are four common reasons that vehicles overheat.

Water Pump Failure

The water pump circulates coolant throughout the engine and cooling system. A worn or damaged pump may not circulate coolant effectively, allowing heat to accumulate inside the engine. Water pumps can also develop leaks or other mechanical problems as they age. Unusual noises, coolant loss, or overheating may accompany a failing pump. 

A Faulty Thermostat

The thermostat controls when coolant flows between the engine and radiator. If the thermostat becomes stuck closed, coolant circulation can become restricted and engine temperatures may rise. 

Low Coolant Levels

Low coolant is one of the most common causes of overheating. Coolant absorbs heat from the engine and carries it through the cooling system to the radiator, where that heat is released. If the coolant level becomes too low, the system may not be able to remove heat effectively. Low coolant can result from leaks involving hoses, the radiator, water pump, or other components. Repeatedly losing coolant should always be investigated by a professional.

Radiator Problems

The radiator releases heat from the coolant before the fluid returns to the engine. A clogged, damaged, or leaking radiator may not be able to dissipate heat properly. Radiator problems may become especially noticeable during extremely hot weather and extended idling.
