WARNING:

Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They are
under pressure, and if you turn the surge tank
pressure cap

even a little

they can come

out at high speed. Never turn the cap when the
cooling system, including the surge tank pressure
cap, is hot. Wait for the cooling system and surge
tank pressure cap to cool if you ever have to turn
the pressure cap.

You can remove the
coolant surge tank
pressure cap when the
cooling system, including
the coolant surge tank
pressure cap and upper
radiator hose, is no
longer hot.

1. Turn the pressure cap slowly counterclockwise.

If you hear a hiss, wait for that to stop. A hiss
means there is still some pressure left.

2. Then keep turning the cap and remove it.
