4 Common Issues that Lead to Engine Overheating

Bay Brothers Automotive • 1 October 2025

Few automotive issues are more stressful than seeing your vehicle’s temperature gauge climb into the red while you’re on the road. Engine overheating is not only inconvenient, but also potentially damaging, as excessive heat can warp components and blow gaskets. At Bay Brothers Automotive, our local mechanics provide expert cooling system repair in the greater Tampa, FL area. Here are four common causes of overheating.


Low/Leaking Coolant

Coolant is vital for regulating engine temperature. If your vehicle has a coolant leak and/or the fluid levels are too low, the engine won’t be able to stay cool under normal operating conditions. Leaks can occur in hoses, the radiator, or the water pump. Regularly checking coolant levels (while the engine is cool) and addressing leaks immediately is one of the simplest ways to prevent overheating.


Faulty Thermostat

The thermostat plays a critical role in controlling the flow of coolant through the engine. When it’s working properly, it opens and closes at the right times to keep the temperature steady. However, if the thermostat gets stuck closed, coolant cannot circulate as it should, leading to overheating. Replacing a faulty thermostat is usually a straightforward repair that can save your engine from serious damage.


Radiator Problems

The radiator is designed to dissipate heat from the coolant as it circulates. If the radiator is clogged with debris, corroded, or has damaged fins, it won’t optimally release heat. A failing radiator fan can also increase the risk of overheating. Keeping the radiator clean and well-maintained is essential to maintaining a safe operating temperature.


Water Pump Failure

The water pump enables coolant to move continuously through the engine and radiator. When the pump malfunctions, coolant flow is disrupted, and heat builds up quickly. Because the water pump is so central to the cooling system, its failure easily results in overheating. Regular inspections can catch early signs of trouble before the pump completely fails.
