When your engine starts to overheat, it’s a sign that something has gone wrong within the cooling system or related components. Driving with an overheating engine can quickly cause major damage, including warped cylinder heads, blown head gaskets, and even total engine failure. Recognizing the underlying causes of overheating is essential for protecting your vehicle and avoiding costlier repairs. At Red Rock Auto Center, our local mechanics provide expert cooling system repair in the greater Sedona area. Here are four common engine issues that often lead to overheating. Low or Leaking Coolant Coolant is the lifeblood of your engine’s cooling system. It circulates through the engine and radiator to absorb and release heat. If your coolant level is too low, or if there’s a leak in the system, the engine will not be able to maintain a safe temperature. Leaks can occur in places such as the radiator, hoses, and water pump. Without enough coolant, heat builds up quickly, pushing the engine into the danger zone. Malfunctioning Thermostat The thermostat regulates the flow of coolant between the engine and the radiator. If the thermostat becomes stuck in the closed position, coolant can’t circulate properly, leading to rapid overheating. This small component plays a big role in maintaining the balance of the entire system. Faulty Water Pump The water pump is responsible for moving coolant through the engine and radiator. When it fails, the coolant can’t flow, and the engine begins to overheat. Common signs of water pump trouble include coolant leaks and grinding or squealing noises. Because the pump is driven by a belt, even a broken or loose belt can disrupt its operation and trigger overheating. Clogged or Damaged Radiator The radiator’s job is to disperse heat from the coolant as it passes through. Over time, radiators can become clogged, reducing their effectiveness. In other cases, physical damage can prevent the radiator from functioning properly. When the radiator can’t cool the coolant effectively, the system overheats and the engine suffers.
