Few things are more stressful for drivers than seeing the temperature gauge climb or steam rising from under the hood. An overheating engine can lead to severe damage if not addressed quickly. Understanding the common causes of overheating can help you take preventive measures and recognize when it’s time for repairs. At Lodi Transmissions, we provide expert cooling system repair in the greater Lodi, CA area. Here are four of the most common reasons engines overheat.

Low Coolant Levels

Coolant is essential for regulating your engine’s temperature. If your vehicle doesn’t have enough coolant, it won’t be able to absorb and transfer heat away from the engine effectively. Low coolant levels are often caused by leaks in the radiator, hoses, or water pump. Topping off the coolant might offer temporary relief, but the underlying leak must be fixed to prevent repeated overheating.

Faulty Thermostat

The thermostat controls the flow of coolant through your engine. When working correctly, it opens and closes at the right times to keep the temperature stable. A faulty thermostat can get stuck closed, blocking coolant from circulating. This quickly leads to overheating, as the coolant won’t move through the system as needed.

Broken Water Pump

The water pump is responsible for pushing coolant through the engine and radiator. If it fails, the circulation of coolant stops, and the engine can overheat shortly thereafter. Common signs of a failing water pump include coolant leaks near the pump, as well as whining or grinding noises. Because the water pump is such a critical component, prompt repair is essential if it shows signs of trouble.

Clogged Radiator

Over time, dirt, debris, and rust can build up inside your radiator, reducing its ability to release heat. A clogged radiator restricts the flow of coolant, causing the engine to run hotter than it should. Regular maintenance, including flushing the radiator, helps prevent this issue.
