1. Park the vehicle on a
level surface. 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.
2. Turn the pressure cap slowly counterclockwise (left)
until it first stops. (Don’t press down while turning
the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.
Then keep turning
the cap, but now
push down as you
turn it. Remove the
pressure cap.

size van models: After the
engine cools, open the air bleed valve on the
thermostat housing.
