Check the Coolant
WARNING: The safest and best way to check the coolant is when the automobile is COLD. Failure to do this can result in severe steam burns, scalding, and other serious personal injury. We do not recommend adding coolant when your engine is warm or hot. If you are in an emergency situation, go to our page how to deal with an overheating car.
NOTE: If you need to add coolant (also known as antifreeze) make sure that you are adding the correct type for your vehicle. You should be able this information in your owner’s manual. Then visually inspect your radiator, hoses, and coolant reservoir for leaks. You should purchase a coolant mixture of 50 percent anti-freeze to 50 percent water.
If you are concerned that your anti-freeze is not pre-mixed, anti-freeze testers can be purchased at any auto parts store and typically cost about $5.00. It is probably a better idea to just replace your current anti-freeze with a pre-mixed version, but if you would like to test it, here is some more information.
TIP: Check the coolant once per year in the fall or before traveling to a colder climate.
Before you start you will need to open the hood.
