How To Stop An Overheating Engine From Leaving You Stranded
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.
As soon as you get any indication that your engine is overheating you need to pull over and switch your engine off. Carrying on, even until you reach a service station or garage, could create a large amount of damage to the engine, especially the cylinder head, which is prone to warping under high temperatures and will be very expensive to replace.
When you get to the side of the street you will need to turn your hazard lights on to indicate you are experiencing an issue to the other drivers. If there is no fire you can lift the bonnet to give the engine a better source of air, thus decreasing the pressure. You do not want to touch the engine as you may be burned.
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 decreased in temperature the first thing to check is the coolant. This is usually the first fluid to be low when your car overheats. By adding water to the radiator you are able to give it fluid. The water should not be too cold as it can crack the container the fluid is held in. Water is not the typical fluid to use, but in an emergency it works fine. The water will dilute the coolant called antifreeze. You will need to have the system flushed by a mechanic before winter to avoid freezing the coolant.
The cap to the coolant filler can be very hot even after the car has cooled down. Steam tends to be trapped inside which will rise, burning your hand. It is best to wait until the outside of the radiator is cool to the touch before opening the cap. You can also use a rag to remove the cap.
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.
