  • 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 counter clockwise 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.
