6. When pressurizing the cooling system, verify that the pressure is maintained.
If the gauge needle drops, it may indicate water leakage. Repair or replace the applicable part.
COOLING SYSTEM CAP INSPECTION [LF]
1. Clean the cooling system cap and the sealed part.
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're sure all the pressure is gone, press down on the cap
using the cloth, turn it, and remove it.
