Downloaded from www.Manualslib.com manuals search engine The coolant level should be at or above near “FULL COLD.” If it isn’t,
you may have
a leak in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine parts, can be very
hot. Don’t touch them. If you do, you can be burned.
Dodbrun the engine if there is a leak. If you run the engine, it
could lose all coolant. That could cause an engine fire, and you
could be burned. Get any leak Pied before you drive the vehicle.

If there seems to be no leak, check to see if the electric engine fans are
running.

If you haven’t found a problem yet, but the coolant level isn’t at or above
near
“FULL COLD.” add a 50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant recovery tank. (See
“Engine Coolant”
in the Index for more information about the proper
coolant mix.)

A CAUTION: i
Jding only plain water to your cooling system can be
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant mix will. Your vehicle’s coolant
warning system is set for the proper coolant mix. With plain
water
or the wrong mix, your engine could get too hot but you
wouldn’t get the overheat warning. Your engine could catch fire
and you or others could be burned. Use
a 50/50 mix of clean
water and
a proper antifreeze.

5. Put the cap back
on the coolant
recovery tank, but
leave the radiator
pressure cap
off.
6. Start the engine
and let it run
until
you can feel the
upper radiator
hose getting hot.
Watch out for the
engine fans.
7. 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.

To Check Coolant:
When your engine
is
cold, the coolant level
should be at “FULL
COLD,” or a little
higher. When your
engine is
warm, the
level should be
up to
“FULL
HOT,” or a
little higher.
To Add Coolant: If you need more coolant, add the proper mix at the
coolant recovery tank.
A CAUTION: I
lhrning the radiator pressure cap when the engine and radiator si:;
-z. *?’
are hot can allow steam and scalding liquids to blow out and
burn you badly. With the coolant recovery tank, you will almost
never have to add coolant at the radiator. Never turn the
radiator pressure cap
-- even q little -- when tken le and
radiator are hot.
