An overheating engine is a serious problem that can lead to costly repairs or even complete engine failure if ignored. When the temperature gauge creeps into the red zone or steam starts rising from under the hood, it’s a clear sign that your engine is too hot. Understanding the most common causes of overheating can help you address issues early and prevent long-term damage. At Freeport Automotive, our local mechanics provide expert cooling system repair in the greater Sacramento, CA area. Here are four common causes of overheating.

Coolant Level Is Too Low

Coolant is the fluid responsible for absorbing heat from the engine and releasing it through the radiator. When coolant levels drop too low due to leaks or evaporation, the system can’t properly regulate engine temperature. Without enough coolant circulating, the engine will overheat. Regularly checking coolant levels and topping them off (while the engine is cool) is essential for preventing this issue.

Malfunctioning Water Pump

The water pump is a key component in the cooling system, responsible for pushing coolant through the engine and radiator. If it fails, coolant circulation is disrupted, leading to overheating. Common signs of water pump trouble include coolant leaks and whining or grinding noises. Because the water pump is vital to cooling system function, a faulty one should be replaced immediately.

Faulty Thermostat

The thermostat regulates the flow of coolant between the engine and radiator. When working correctly, it opens and closes based on temperature to keep the engine within the optimal range. If the thermostat gets stuck closed, coolant can’t circulate, trapping heat inside the engine. This can cause the temperature to spike quickly. Replacing a malfunctioning thermostat is a relatively simple repair that can save your engine from severe damage.

Radiator Problems

The radiator’s job is to release heat from the coolant into the air. If it’s clogged, leaking, or has a damaged fan, it won’t be able to dissipate heat effectively. Debris can also build up in the radiator over time, restricting coolant flow. Regular flushing and cleaning can help keep the radiator in good condition and prevent overheating issues from developing.
