1. 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. Turn the pressure cap slowly
counterclockwise (left) about one

-

quarter turn 

and then stop.

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 slowly, and

remove it.

3. Then fill the coolant surge tank with the proper

mixture, to or above the fill mark at the forward 
edge of the surge tank.
