Your car’s engine should never surpass the standard temperature range of 90 to 104 Degrees Celsius. Anything beyond that means trouble. You’ll be lucky if you drive a Volvo as the check engine light will most likely warn you of the heating engine early enough for you to either fix the problem or seek professional help. Either way, dealing with an overheating engine is hardly ever a walk in the park. You first have to find out where the problem is. It could be something so subtle that the now common car diagnostics systems cannot detect. The reasons behind the soaring engine temperatures can be many, as you are about to find out. The most common ones include:
Faulty Water Pumps
The water pump is without a doubt the most important part of the engine’s cooling system. It propels the flow of coolant throughout the system. This means engine overheating is inevitable once the water pump stops cooling. The pump can malfunction due to a number of reasons. Rust and corrosion are good examples why most pumps fail. In some cases, the problem may not even be the pipe but a broken or poor installed serpentine engine belt. As simple as it looks, the belt turns the pump so if there is something wrong with it, the engine will certainly overheat.
The thermostat is another important component of the engine cooling system. Its main function is to monitor engine temperature. It also regulates coolant flow to the engine through a valve. If the engine gets too hot, it quickly opens it valve and allows the coolant to flow to the engine so that it can cool down temperatures. If for one reason or another, the thermostat gets stuck in a closed position, the coolant won’t simply enter. The engine will then rapidly overheat.
You can be sure of an overheating episode anytime your radiator malfunctions. Check your car’s thermostat. Check the coolant too. If these two work properly, then the main culprit is the radiator. That is because the radiator is designed to work with the hot coolant that comes from the engine block. It simply returns the hot coolant to the system before it allows the coolant to run its course one more time. If there happens to be something wrong with the fan or the radiator, temperatures will remain high.
In some cases, the problem is not even anywhere near any of the primary parts that support the cooling system, but in the support piping. In such cases, the problem will manifest as a coolant leak. This can be difficult to note on time or find. That is why taking your car for servicing regularly is important as your mechanic can easily notice the problem during routine servicing and inspecting. The leak won’t just allow air to get sucked into the cooling system and create blockage. It will also prevent the coolant from circulating. Eventually, the engine will get chocked by heat. The cooling systems can also get blocked up by engine sediment or even rust.
