Specifications

1. You can remove the radiator pressure cap when
the cooling system, including the radiator pressure
cap and upper radiator hose,
is no longer hot.
If you hear a hiss, wait for that to stop. A hiss
means there
is still some pressure left.
2. Then keep turning the pressure cap, but now push
down as you turn it. Remove the pressure cap.
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it
will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
