Most people know the green stuff in your radiator keeps your engine from turning into a block of ice in the winter, but did you know that it also helps keep things cool in the summer? All too often people are driving around with just water in their radiator because they think they don't need the green stuff until it gets cold.
Radiator coolant actually raises the boiling point of the water, allowing it to carry more heat away from the engine, and that means cooler running. If you're running low, things can get steamy fast.
Luckily it only takes a second to check your coolant level. Most cars these days have an opaque coolant overflow tank right next to the radiator. It's white plastic, but you can see inside to see if there's enough juice to keep things safe. You'll also see markings on the side telling you the low and high levels to work with. Always check your coolant level when the car is cold.
If your levels are good, no need to go any further, enjoy the peace of mind. But if you're low, you'll need to top it off. Your engine takes a 50/50 mixture of coolant and water. In the old days, you had to make measurements yourself and test the mixture to get it right. But since we live in the age of convenience, you can now buy premixed coolant that's ready to pour. For a simple topping off, I recommend going this route. It might cost a buck more, but you're in for much less mess.
:)The best way to prevent over heating is doing regular maintenance on your vehicle.
