What are some of the most common causes of overheating?
When your car’s temperature gauge starts climbing into the danger zone, it’s a warning that shouldn’t be ignored. Overheating can quickly lead to severe engine damage, resulting in costly repairs or even complete engine failure. Understanding the most common causes of overheating can help you recognize issues early and keep your vehicle running smoothly. At Roswell Transmission and Car Care, we provide expert cooling system repair in the greater Roswell, GA area. Here are four of the most frequent culprits behind an overheating engine.
Radiator Problems
The radiator is responsible for cooling the hot coolant before it cycles back into the engine. When the radiator is clogged, damaged, or leaking, it can’t perform its job effectively. This can result from corrosion, road debris, or other issues. If your radiator fan also fails, airflow decreases, further increasing the likelihood of overheating.
Water Pump Failure
The water pump is critical to the cooling system, pushing coolant through the engine and radiator. When it fails, circulation grinds to a halt, and temperatures soar. Common signs of a failing water pump include coolant leaks around the pump, whining noises, or engine overheating even when coolant levels are sufficient. Because of its crucial role, water pump issues should be addressed immediately.
Low Coolant Levels
Coolant plays a crucial role in regulating your engine’s temperature. If the system is running low due to leaks, the engine won’t have enough fluid to draw heat away. Without proper coolant circulation, the engine quickly overheats. Regularly checking fluid levels and topping off coolant as needed (while the engine is cool) is one of the simplest ways to prevent this issue.
Faulty Thermostat
The thermostat regulates the flow of coolant. If it becomes stuck closed, coolant can’t circulate, causing the engine to heat up rapidly. A malfunctioning thermostat is one of the more common and affordable issues behind overheating, but it still needs prompt replacement to avoid major engine stress.
