Car Maintenance Guide - Engine Overheating

Snapshot: Here are some ways by which you can cool off your car’s engine and avoid any costly damage.

The global automotive industry has hugely developed, and thanks to the advanced technologies, today’s engines are much refined and sophisticated that before. Thus, engine overheating is also a rather uncommon thing today. However, even a few years ago, engine overheating was a common worry of the car owners. Nevertheless, even today denying the highly evolved technologies and the great innovative motor engineering, cars can still overheat causing a lot of inconvenience for the car owners.

Even some of the highly acclaimed high-tech cars can also face this disgraceful yesteryear problem of overheated engines at times. A number of factors might result in engine heating, such as very hot weather conditions, excessively steep climbs or very long continuous driving or even bad traffic when a lot of braking is involved. In a situation of engine overheating, the car’s engine gets so hot that steam from beneath the bonnet. You can’t simply ignore it, as your car will break down and can severely damage the engine.

Here are some ways by which you can cool off your car’s engine and avoid any costly damage.

Turn off the Air Conditioner

As soon as you notice that the car’s engine is overheating, the first immediate thing you should do is to turn off the car’s A.C and roll down the windows. A car A.C apply a whole lot of pressure on the motor and turning the A.C takes that extra load off the engine helping it to cool down.

Turn on the heater

This one is for the global cars or the premium cars. If turning off the A.C does not help then you can turn on the car heater (if it has one). This would pass on the excessive motor heat from the engine compartment to the car’s cabin, and help in cooling the engine pretty fast. However, this will certainly cause a lot of discomfort for the car’s occupants, especially in hot weather conditions.

In case of bumper to bumper traffic jams

Lengthy and heavy traffic jams, especially during the summers can easily cause a car engine to get overheated. Long periods of bumper to bumper traffic jams with a series of quick, sudden breaks combined with occasional hitting hard on the accelerator can actually exhaust even the most fined engines, and cause them to overheat. In such conditions you need to shift the gear to Neutral rev the motor mildly. This should rotate the fan more and increase the water pump action to help the engine’s mechanism of cooling.

A good thing to keep in mind for the sake of your fine car is to keep a slow steady speed level in such heavy traffic conditions. Only move your car when the vehicle in front is some distance away. And, certainly try not to brake suddenly. This will keep your car engine healthy for longer as its stress levels will be low.

When can engine refuses to cool

So, there are already some reasons and solutions of engine overheating known to you. However, what happens if your car engine refuses to cool off even after trying out all these tips mentioned above? In such situations, of course you don’t have any more options other than parking your car on the side of the road, and turning off the engine to give it some time to cool down. This certainly works best and fast as well. Moreover, you can also open the hood of the car and keep it lifted in its highest position by locking it in place, in order to dissipate the heat faster from the engine bay.

However, when opening the hood of your car in such conditions, you should be extremely careful or you might get severe steam burns. It is best to keep the engine turned off for sometime by parking the car in some shady area for sometime before you try to open the hood. Never attempt to open the bonnet with bare hands as the overheated motor will certainly make the metal sheet excessively hot. The bonnet should be up with the help of thick towel. Make sure of keeping ample amount distance between yourself and the bonnet to avoid being burnt by direct steam. You can also open the hood very slowly at first to help the emanating steam come out slowly rather than all together, which might burn you.

What should be done once the hood is open?

Once you successfully open the car’s bonnet and all the steam is out completely, rather than directly reaching for the usual radiator cap to pour some water in the radiator, consider these other important points first. Again, first the radiator’s lid should not be touched or removed with bare hands, as this too will be naturally extremely hot with the boiling steam all over the engine compartment. Again, a thick towel or cloth can be used to open the radiator lid.

Keep the radiator to cool off for some time, and do not pour water immediately. In case you are in a hurry and have to pour water, when the engine is still not completely cool, then ensure the water that you are pouring in the radiator is mild warm and not very cold. Pouring cold water in the hot radiator will cause extreme thermal pressure, which can even crack the motor block, severely damaging it. While adding this lukewarm water to a still warm engine, you should ensure pouring it slowly, while keeping the engine running in Neutral shift.

Check the Coolant Level and Hoses

You should also check the coolant level to see if it has gone below the company’s recommended mark. Simply open the coolant reservoir, check the fluid level. In such situations it is best to take professional help.

You should also check all the radiator hoses for possible damage, blockages or disconnections. Disconnected hoses can simply be reattached, but replacing damaged ones require professional attention.
