An overheating engine is a serious issue that should never be ignored, as it can cause significant damage if not addressed quickly. Understanding the common reasons why cars overheat can help you recognize problems early and take preventive action before they escalate into costlier repairs. At Everett Transmission & Auto Repair, our local mechanics provide expert cooling system repair in the greater Everett, MA area. Here are four frequent culprits of engine overheating.. Faulty Thermostat The thermostat controls the flow of coolant through the engine and radiator. If it becomes stuck closed, coolant cannot circulate, trapping heat inside the engine. This often leads to a rapid rise in temperature and can result in severe engine damage if not repaired. Replacing a faulty thermostat is usually a straightforward and relatively inexpensive fix. Radiator Problems The radiator is responsible for dispersing heat from the coolant into the air. When it becomes clogged with debris, corroded, or damaged, it loses its ability to transfer heat efficiently. A failing radiator fan can also contribute to the problem, as it prevents proper airflow. Keeping your radiator clean and ensuring the fan works properly are key steps to avoiding overheating. Low Coolant Levels Coolant plays a vital role in regulating engine temperature by absorbing heat and carrying it away from the engine block. When coolant levels are too low, the system cannot do its job effectively, causing the engine to run hot. Leaks in the radiator, hoses, or water pump are often the culprits behind coolant loss. Regularly checking fluid levels while the engine is cool can help prevent overheating due to this issue. Water Pump Failure The water pump keeps coolant moving through the engine and radiator, making it an essential component of the cooling system. If the pump fails, coolant circulation slows or stops entirely, leading to overheating. Water pump problems often come with warning signs like coolant leaks or whining noises, which should be addressed immediately.
