A You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol and it will burn ifthe engine parts are hot enough. Don't spill coolant on a hot engine. When the coolant in the coolant recovery tank (or coolant surge tank) is at or above FULL COLD, start your vehicle. If the overheat warning continues, there's one more thing you can try if you have a 2.2L L4 engine. You can add the proper coolant mix directly to the radiator, but be sure the cooling system is cool before you do it. A I Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They are under pressure, and if you turn the radiator (or coolant surge tank) pressure cap-even a little-they can come out at high speed. Never turn the cap when the cooling system, including the radiator (or coolant surge tank) pressure cap,is hot. Wait for the cooling system and radiator (or coolant surge tank) pressure cap to cool if you ever have to turn the pressure cap. I 79 II . .
