The engine coolant temperature gauge is located on your instrument panel, and displays how hot the coolant in your engine is. This display can be three colors: blue (when the coolant is cold), gray (when the coolant is a normal temperature), and red (when the coolant is hot). If the coolant is even hot, stop the vehicle as soon as possible, and let it cool down.
