system can
blow out and burn you badly. Th'ey
are under pressure, and if
you turn the radiator
pressure cap
-- even a little I- they can come out

How to Add Coolant to the Radiator
I NOTICE:
~~
Your engine has a specific radiator fill procedure.
Failure to follow this procedure could cause your
engine to overheat and be severely damaged.
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.
Turn the pressure cap slowly counterclockwise until
it first stops. (Don't press down while turning the
pressure cap.)
I
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.

proper
mix, up to the
base of the filler neck.

valve. Otherwise, close
the valves after the

8. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch
out for the
engine fans.
9. By this time the coolant level inside the radiator
filler neck may be lower.
If the level is lower, add
more
of the proper mix through the filler neck until
the level reaches the base of the filler neck.
10. Then replace the
pressure cap. At any
time during this
procedure
if coolant
begins to flow out of
the filler neck, reinstall
the pressure cap. Be
sure the arrows on the
pressure cap line
up
like this.
11. Check the coolant in the recovery tank. The level in
the coolant recovery tank
should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine is cold.
