Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline or
diesel fuel, oil, coolant, brake fluid, windshield
washer and other fluids, and plastic or rubber. You or others could be burned. Be careful
not to drop or spill things that will burn onto
a hot engine.
