To keep your car running at the best temperature, keep an eye on your engine coolant. Engine coolant is the liquid in your radiator that circulates to keep temperatures normal. Although the name might trick you, engine coolant actually performs several important duties. It will cool down a overly warm engine, but it will also keep a cold engine from freezing over. You may also hear this fluid called "antifreeze." Coolant is often brightly colored. Some of the most regular colors are green, red, or blue. It's smart to perform this check before the extremes of winter and summer weather. Having your car prepared for the changing seasons helps prevents overheating or freezing, which can lead to an expensive repair bill. If you notice the level is lower than it should be, it's simple to add more and keep your car running well.To monitor your coolant, first find the coolant reservoir. If you aren't sure where this is, check your vehicle user manual. Make sure your engine isn't too hot before you begin. On the side of the reservoir you will find a level indicator, with a maximum and minimum indication. If you need to fill your coolant, get a funnel and the appropriate coolant for your car, which will be listed in your vehicle user manual. Fill it to the maximum line, replace the cap, and you are done!This is an easy task that can be done at home.
