There are many reasons why your car overheats. It could be anything from low coolant levels or a faulty water pump to a problem with the radiator. Some overheating issues are easy to take care of, while others can cause severe damage to your engine and will need the expertise of a certified technician.
Car Overheating Guide
The Coolant Is Too Low
Coolant regulates your car’s engine temperature, and an inadequate amount can lead to temperature spikes. If the coolant is low, the reservoir is empty, or you notice orange, green, or blue puddles underneath your car, it could indicate a coolant leak. Remember to check the coolant levels monthly and refill as needed according to the manufacturer’s recommendations.
It’s important to change the coolant at the specified intervals as old coolant may not effectively cool your engine, which will also lead to overheating. Your owner’s manual contains details on how to refill the coolant and when to replace it.
The Coolant Is Old and Dirty
If the coolant is old or dirty, its pH levels change and it loses its protective qualities. This sets off rust and sludge buildup that can affect your car’s cooling system.
This substance can’t move freely through the system, clogging passages and causing your engine to overheat. That is why flushing the coolant at the intervals recommended by your vehicle’s manufacturer is so important to help ensure your engine operates at the proper temperature.
There’s Not Enough Engine Oil
Oil is a lubricant that also controls your engine’s temperature by reducing friction. Insufficient engine oil will increase friction and heat generation, potentially damaging your engine.
The Thermostat Is Faulty
Your car’s thermostat regulates the flow of the coolant. When the thermostat is faulty, it can’t keep the engine at the proper temperature, resulting in temperature changes under the hood and overheating.
The Water Pump Is Broken
The job of the water pump is to circulate coolant through your car’s cooling system. The coolant then absorbs the heat before being sent to the radiator for cooling and returning into circulation.
You’ve Got Radiator Issues
Issues with your car’s radiator can also contribute to overheating as it works alongside fans to lower the coolant temperature and draw heat from the engine. If the fans fail to operate, it impairs the radiator’s ability to regulate the temperature, causing an increase in heat. Rust buildup and clogged radiator fins will also prevent adequate cooling and cause overheating.
