WARNING
Removing radiator cap
• Never attempt to remove the radiator
cap while the engine is operating or
hot. Doing so might lead to cooling
system and engine damage and could
result in serious personal injury from
escaping hot coolant or steam.
• Turn the engine off and wait until it
cools down. Use extreme care when
removing the radiator cap. Wrap
a thick towel around it, and turn it
counterclockwise slowly to the first

is released from the cooling system.
When you are sure all the pressure
has been released, press down on the
cap, using a thick towel, and continue
turning counterclockwise to remove
it.
