… are among the problems that you may face if you continue driving with an overheating engine. So, why do cars overheat and what should you do if it occurs to you that your BMW engine is overheating??? This blog post covers it all… So, if you do not want to incur costly repairs resulting from engine overheating, you should read this blog post all the way through.

Why Do Car Engines Overheat?

As a car engine operates, it doesn't just produce mechanical torque... it produces a lot of heat energy as co-products. To get rid of this excess heat and maintain optimal engine temperature, a network of parts is involved that is collectively known as the cooling system.

Usually, a malfunction in the cooling system causes the engine temperature to rise beyond the permissible limits. So, if your BMW engine temperature gauge is reading high, there's a good chance that a malfunction in the cooling system is to blame. This brings us to a question; what can go wrong with the cooling system of a vehicle that may result in engine overheating??? Let's find out…

Cooling System Faults That May Result In Engine Overheating

#1- Coolant leak. In order for your vehicle's cooling system to maintain a constant engine temperature, there must be enough coolant left in the coolant reservoir. If there is a leak somewhere through which coolant is leaking out, it can eventually contribute to engine overheating.

#2- Damaged pump. In order for your car's engine temperature to remain within permissible limits, the coolant needs to continuously circulate between the engine and the radiator. If the pump fails, coolant circulation will stop. As a result, the engine may overheat.

#3- Radiator issue. If there is something off with the radiator that’s interrupting heat dissipation, it can also contribute to engine overheating. A defective thermostat can also result in engine overheating.

Signs of Engine Overheating You Need To Be Aware Of

Hint #1- High engine temp. Gauge reading

This is perhaps the most obvious indication of engine overheating in a vehicle. There are sensors incorporated into the engine and other crucial car parts to monitor how they are operating. There's even a sensor to monitor engine temperature. It is because of this sensor you get to keep track of your engine temperature. If your engine temperature gauge reads high, it simply suggests that your BMW engine is on the brink of overheating.

Hint #2- Steam under the hood

Another obvious sign of engine overheating in a vehicle is the release of dense white steam from under the hood. The smoke could also suggest an electric short circuit or something like that… Whatever may be the reason for the formation of this smoke, it should not be taken lightly. You must find out exactly what the problem is and proceed accordingly.

Hint #3- Thumping or ticking noise

You can tell if your vehicle's engine temperature has reached extremes just by listening to the sound of your engine. If you feel like your car engine is making a strange thumping or ticking noise, it could be a sign of overheating. You may need careful inspection to pinpoint the source of the noise.

Hint #4- Reduced engine power

Another important sign that your engine has overheated is a significant drop in the engine's torque output. An interesting fact about heat engines is that they generate mechanical torque by burning hydrocarbons. But, guess what??? There is a limit to which they can tolerate heat. Increased temperatures may result in reduced performance of these engines.

Hint #5- Flashing warning light

Increased engine temperature may also set off your BMW's check engine light. No matter how unusual and strange it may seem, it is true…

What Options Do You Have?

Consider pulling your vehicle over as soon as you notice an abnormal engine temperature gauge reading. If you are late for something and you don’t have time for any such activities, try turning the AC off and turning the heat up. This may give you some time so that you can reach your destination or the service center safely. Whatever it is that’s been causing the engine temperature to spike abnormally must be identified and taken care of.
