COOLING SYSTEM SERVICE WARNINGS[L3 WITH TC]

id011239800200

Warning

• 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.

• Depending on the vehicle, the cooling fan may operate suddenly even when the ignition switch is

turned off. Therefore, keep hands and tools away from the cooling fan even if the cooling fan is
not operating to prevent injury to personnel or damage to the cooling fan. Always disconnect the
negative battery cable when servicing the cooling fan or parts near the cooling fan.
