An overheating engine is a problem that should never be ignored. Your car's cooling system works continuously to regulate engine temperature, but problems with its components can prevent it from effectively removing excess heat. Continuing to drive while the temperature gauge is in the danger zone can result in serious engine damage and costly repairs. Understanding common causes of overheating can help you recognize trouble and seek professional service before a minor problem becomes a major one. At Everett Transmission & Auto Repair, our local mechanics provide expert cooling system repair in the greater Everett, MA area. Here are four common causes of engine overheating.

A Faulty Thermostat

The thermostat regulates the flow of coolant between the engine and radiator. When it becomes stuck closed or otherwise malfunctions, coolant may not circulate properly, causing engine temperatures to rise. Professional diagnostics can help determine whether the thermostat is responsible and whether replacement is necessary.

Water Pump Problems

The water pump is responsible for circulating coolant through the engine and cooling system. A damaged, worn, or leaking water pump may not move coolant effectively, allowing heat to build up inside the engine. In some cases, a failing water pump may also produce unusual noises or cause visible coolant loss. Prompt attention can help prevent overheating from causing additional engine damage.

Low Coolant Levels

Low coolant is one of the most common reasons an engine may overheat. Coolant absorbs heat from the engine and carries it to the radiator, where the heat is released. If the coolant level drops too low, the system may not be able to regulate temperature effectively. Low coolant can result from leaks involving hoses, the radiator, water pump, or other components. If you repeatedly need to add coolant, have the system inspected to find the source of the loss.

Radiator Issues

The radiator releases heat from the coolant before the fluid returns to the engine. A radiator can become clogged or damaged, reducing its ability to dissipate heat. Leaks can also cause coolant loss and contribute to overheating.
