The subject vehicles may have been filled with an improper concentration of coolant and water. Under high load
driving conditions this could cause the high engine coolant temperature warning light to flash or illuminate and the
engine to overheat.
V. WORK PROCEDURE
•
•
•
Never remove the cooling system cap or loosen the radiator drain plug while
the engine is running, or when the engine and radiator are hot. Scalding
engine coolant and steam may shoot out and cause serious injury. It may
also damage the engine and cooling system.
Turn off the engine and wait until it is cool. Even then, be very careful when
removing the cap. Wrap a thick cloth around it and slowly turn it
counterclockwise to the first stop. Step back while the pressure escapes.
When you are sure all the pressure is gone, press down on the cap using
the cloth, turn it, and remove it.
1. INSPECT COOLANT TEMPERATURE
