To help prevent overheating for the vehicle, always remember to check all the fluids of it. During the hot summer months, the coolant should always be inspected and at the proper level. If it is low, you will want to remember to add some so that your radiator does not become damaged. Also remember to never add coolant to a hot engine. Make sure the engine has had time to cool down before you remove the cap or you pour in the coolant. This will help prevent you from becoming burned from the pressure.
Prevent issues with parts
You can also help determine if the vehicle is overheating by the temperature gauge that is on the dashboard of your vehicle. If it starts to increase, then your engine will be getting too hot. When it gets into the red warning area, you will want to prevent further damage to the radiator and engine. Pull the vehicle over when it is safe to do so, and turn the vehicle off. This can allow it some time to cool down so it does not do further damage to the engine. You can also open up the hood of the vehicle to allow the heat and steam to clear out quickly.
Notice odd noises
As you get back in your vehicle, make sure that it does not make any odd noises or sounds when you start it. If you hear something, especially if it is high pitched, it could mean a part is starting to fail. Check the coolant, and if it is low, more should be added. If you cannot drive it, you may also need to have it towed. This will be the best option to maintain the condition of the vehicle, without putting any extra strain or damage to the various parts of it.
