“What causes a car to overheat?” is a question that drivers only have when the temperature gauge begins to climb.
You would probably like to think that your car is as reliable as they come. Unfortunately, this isn’t always the case. Car overheating is an issue that can lead to costly repairs and unexpected breakdowns. An overheating car could leave you stranded somewhere on the roadside.
Let’s discuss some of the causes of car overheating, so you can take proactive steps to prevent breakdowns.
Common causes of car overheating
Car overheating can be caused by various issues within the car’s cooling system. Understanding some of the common causes of car overheating is important. With this information, you could potentially avoid being stranded by an overheating car.
Cooling system leaks
An empty coolant tank could be a sign of a cooling system leak. The leak could be in the radiator, hoses, or water pump, and can lead to a loss of coolant. Leaks in your cooling system can often be identified by spots or puddles on the ground. If not repaired promptly, a cooling system leak could cause your car to overheat.
Low coolant levels
Driving without proper levels of coolant may cause your car to overheat. Low coolant levels can reduce your car’s cooling system’s ability to regulate engine temperature. If coolant levels are lower than the manufacturer’s recommendation, refill or top up the levels with new coolant. If you are unsure where the coolant tank is located, be sure to refer to your car’s owner’s manual.
Broken/blocked radiator
Radiators help to reduce heat from the engine by decreasing coolant temperatures. Blockages in your radiator, caused by debris, dirt, or corrosion, can stop the flow of coolant.
Furthermore, if your radiator fan isn’t working properly, your radiator won’t be able to extract heat from the coolant. Either one of these instances will cause your car to overheat and potentially breakdown.
Faulty thermostat
Your car’s thermostat regulates the coolant flow through your car’s engine. If your thermostat is faulty, it may not be able to detect high temperatures. This will hold up the flow of coolant, and your engine will overheat.
Low engine oil
Your car’s engine is made up of hundreds of moving parts. Engine oil provides lubrication to these moving parts to reduce friction and heat. If your car’s engine oil is too low, there will be more friction between the moving parts. This will cause a buildup of heat and can cause your engine to overheat.
