How To Add Coolant To The Radiator - Oldsmobile 1995 88 Owner's Manual

How to Add Coolant to the Radiator
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.
Turn the pressure cap slowly to the 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.
2. Then keep turning
the pressure cap,
but now push down
as you turn it.
Remove the
pressure cap.
3. Fill the radiator
with the proper
mix, up to the base
of the filler neck.
