Nobody wants to deal with an overheated engine, but when it happens, you must react quickly. One sure sign is when your temperature gauge is reading hot. The first thing you do is pull over and shut the vehicle off. This does not mean in five minutes it means NOW! While some engine damage may have already occurred, hopefully shutting the vehicle off as soon as you notice a problem can minimize it. You now have two courses of action: call a tow truck, or try to find the problem to see if you can repair it on the spot. Read More
