Ever wondered what causes engine overheating? As you can imagine it can be incredibly stressful for any driver to find an overheating engine, especially when you’ve broken down. But quite honestly, there’s no reason why you should endure such trauma when the fact is, there are only a few reasons for engine overheating.
A low coolant level is the most common cause of an overheated engine. For your engine to operate properly, the cooling system relies on the coolant to circulate and remove heat. If you don’t have enough coolant in there to do the job, heat will begin to build, causing the engine to overheat.
Whenever the engine appears to be running hot, the first thing you should do is to check your coolant level. I must stress however, that you should never touch the radiator cap whilst the engine is hot as this can cause unnecessary burns and injuries.
Your engine can also begin to overheat, if you have an electric fan that isn’t coming on. The purpose of the fan is to draw cooler air through your radiator when your car isn’t travelling fast enough. To remain on the safe side, you should always keep an eye on your temperature gauge, especially when you find yourself stuck in traffic. If it starts to creep into the danger zone, you should look under the bonnet to see if your electric fan is running. If it’s not, you should find out why. There are two usually causes to this: either your fan won’t come on at all or the switch that tells your cooling fan to come on isn’t working properly.
There are still a lot of vehicles out there that rely on a car fan belt to drive the engine’s cooling fan. If you see a belt attached to your engine then you’re in this club. Fortunately, the price to repair and replace this is always cheaper than those who don’t have one.
As your car accumulates its miles, your radiator could start getting clogged. This is normally caused by a build-up of rust, dirt and sediment that greatly impedes the flow of coolant through the cooling system. To limit the chances of this happening you should flush your radiator once a year.
A hot engine is never good and you should always try to fix the problem as quickly as possible. An overheating problem could cause further damage that would require you to replace the entire engine. It’s an issue that could be avoided and prove very costly if nothing is done about it. Please read our other blog, for more answers on what to do should your engine overheat.
