3800 V6: Recovery Tank Level
l I I
The coolant level should be at or above the FULL HOT
mark. 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.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see if the electric engine fan is running.
If the engine is
overheating, the fan should be running.
If it isn’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 the
FULL HOT mark, 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.)
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts. Use
the recommended coolant.
When the coolant in the coolant recovery tank is at or
above the
FULL HOT mark, 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 radiator, but be sure the cooling system
is
cool before you do it.

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.
