What to Do When Your Vehicle OverheatsJul 22, 2013 10:05AM ● By Darcie Dingman
It is important to do what you can to prevent your vehicle from overheating in the first place. Making sure to use the proper coolant for your vehicle is extremely important. Not all coolants are safe for all vehicles. Also, making sure that there is enough coolant in your system before driving is going to save you from a possible overheating scenario. If you notice that your vehicle is overheating—steam coming out of the hood and/or your temperature gauge going past the halfway mark and into the red zone—turn off your air conditioning and turn on your heat to full blast. Doing this will transfer some of the heat away from the engine to the inside of the vehicle.
Pull over, especially if there’s not a service station nearby, and turn the engine off. Pop the hood, but let it cool down before completely opening it. NEVER open the radiator cap while the vehicle is still hot; this is very dangerous. The radiator cap should be cool to the touch before opening. Look in the coolant reservoir to see if there is coolant in there. It is always a good idea to carry a bottle of coolant with you. In a pinch, you can use water.
If you have antifreeze with you, fill your reservoir with the coolant once your vehicle has cooled down. Your vehicle manufacturer should have stipulations on which types of antifreeze to use. Some are premixed; others need to be mixed with a 50/50 combo of coolant and water. If your radiator is not properly holding the fluid, there could be a leak somewhere, and it’s important to get it checked immediately.
If the vehicle does not seem to be cooling down, and there is not a service station nearby, it may be necessary to call roadside assistance for a tow.
