Is your engine’s temperature gauge creeping up into the red more often than not? This is a bad sign. Kirk’s Auto Care warns that driving an overheating engine can cause catastrophic damage, including cracking the engine block. It’s best to pull over and turn off your automobile to prevent heat-related consequences. What are the causes of an overheating engine? Here are five of them.
1. Oil Is Low
Motor oil is responsible for lubricating the engine, but it does a lot more than that. It also cleans away dirt and debris as it lubricates. One of the most important things that oil does in your engine is to help to keep it cooler. If your oil is old and worn out, or if there are oil leaks in your engine, that can contribute to engine overheating problems.
2. Coolant Is Low
Coolant is the first thing you might think of when your car starts to overheat and for good reason. The coolant flows through the radiator, the water pump, and a variety of hoses to help the engine oil keep your engine cooler. If your coolant reservoir is dry, this means that there’s not enough coolant in the system and it needs to be topped up.
Hoses, gaskets, seals, and the radiator itself… If any of these things spring a leak, then coolant is leaking out of the cooling system. Often the very first sign that you’ve got a leak is that you’ll find puddles or drips of coolant underneath the car. It’s a good idea to check the cooling system hoses regularly to make sure that they’re not brittle and don’t have holes.
4. Malfunctioning Thermostat
One really simple fix to engine overheating problems is the thermostat. This tiny part regulates coolant and ensures that coolant is flowing when it needs to. When the thermostat stops working, the cooling system has no guidance and stops functioning, i.e., stops circulating coolant through the engine which causes the car to overheat.
5. Water Pump Failure
The water pump is responsible for making sure that all the coolant keeps moving through the cooling system as it should. Gaskets can leak coolant from the water pump, and that’s troublesome enough. If the water pump fails, which can happen with any moving part, then no coolant is getting pumped where it needs to go.
