(B) Coolant-high fillreservoir with
(C) Electric engine fans

If the caulant inside the csolaht
recovery tank is boiling, don’t do;
anything else until it cuols dam.
When it is cwl, rtmove- the .coolant
reqvery tank cap and I-ook at - the
dipstick. The
Coolant level should be at
or above-COLD.
If it isn”t, you may have a leak in the
radiator hoses, heater hoses, radiator,

or coolant pump.

A Heater adradiator hoses, ’.-
.and oiher enginelparts, can
.be.very-hot. Don’t touch them ...If
you do, you canbe burned.
Don’t run 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 fixed before
you drive the vehicle.

If there seems to be no leak, check to
see
if the electric engine fans are
running.
If the engine is overheating,
both fans
should be running. If they
aren’t, your vehicle needs service.
How to Add Coolant to the Coolant
Recovery Tank
If you haven’t found a problem yet, but
the coolant level isn’t at
or above
COLD,
add a 50/50 mixture of clean
water (preferably distilled) and a proper
antifreeze at the coolant recovery tank.
(See the
Index under Coolant for more
information about the proper coolant
mix. )

Downloaded from www.Manualslib.com manuals search engine .-
Adding only plain:water.to
yam 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.
You can'bebumed if you

parts. Coolant contains'ethylene
glycol and it will burn .if the engine
parts are hot enough. Don't spill
coolant on a hot engine.
When the coolant in the coolant
recovery
tank is at or above COLD,
start your vehicle.
If the overheat warning continues,
there's one more thing you can try. You
can add the proper coolant mix directly
to the coolant high fill reservoir, but be
sure the cooling system is cool before you
do it.

High FM Reservoir-LT1 On/y 1. You can remove the coolant high fill
reservoir pressure cap when the
