Stop, Cool down, and Wait: Taking Care of the Overheated Engine

By Ethan Melandri

To tell if your engine is overheating there are a few warning signs that your car has. The first is the water temperature gauge. When this gauge begins to increase in temperature going towards the red zone it means your car is too hot. This is then followed by the second system, which is the warning light somewhere on your dash. You may even be seeing steam coming from the bonnet at this point. At any time when you see these warning signs it is imperative that you stop the car. Your vehicle can be severely damaged by an overheated engine to the point that repairs are costly.

If your vehicle is overheating you need to pull off the street and turn the vehicle off immediately. You do not want to continue to a mechanic garage or station as this will result in irreparable damage to the engine. The cylinder head when it gets too hot will warp or crack, thus replacement is needed in that situation.

Once safely parked on the side of the road, switch on your hazard lights to warn any following drivers of your problem. Providing that there is no fire present you can open the bonnet, to give the engine a chance to cool down, however do not be tempted to touch any of the engine parts at this point, as it is very likely that you will be burnt.

Be prepared that it may take quite some time for the engine to cool down sufficiently so be ready for a long wait. If your vehicle has overheated when it is dark, switch on your sidelight bulbs to improve the visibility of your vehicle to other road users and consider turning on your headlight bulbs to help you see what your are doing.

After the engine has cooled you will need to check the coolant. The coolant can be found in the radiator and the fluid reservoir. If there is a lower level of coolant in the container you can add water to it in an emergency. Adding water to the coolant will dilute it, which means it can freeze in the winter. This is because antifreeze properties exist in the coolant. You will need a professional mechanic to flush the system and repair the diluted fluid before winter.

Even if the engine has cooled down the coolant may still be hot and undoing the coolant filler cap can release scolding hot steam onto your hand. Therefore wait until the radiator is cool enough to touch before opening the coolant filler cap and cover your hand with a rag for added protection.

Stand a way from the engine when you are filling it with water so that you will not be splashed by the warmer liquid. You will also need to stop frequently to check the fluid levels as there is a minimum and maximum line to fill to. Once you have filled the reservoir you can check the engine temperature gauge. If it is back to normal you may proceed on your drive.

Keep in mind that it is safe to drive again, but there is probably another problem related to the overheating of the engine. You should get your car into a repair shop as soon as you can, and avoid long drives. If the car overheats again after a short time of driving again you will need to stop, call roadside assistance, and have them tow you to a garage. - 21392
