RWARNING
Never remove the coolant recovery cap
while the engine is running or hot.
*
[SV17750(ALL)03/95]
If the engine coolant has not been checked for a
long period of time the engine coolant reservoir
may eventually empty. If the engine coolant
reservoir empties, check the engine coolant level
in the radiator. Read the following warnings
before removing the radiator cap. If it is
necessary to fill the radiator, refer to theEngine
Coolant Refill Procedurein this chapter for
instructions.
[SV17765(ALL)08/95]
1. Before you remove the radiator cap, turn the
engine off and let it cool. Even when the
engine is cool, be careful when you remove
the radiator cap.
[SV17770(ALL)05/95]
2. When the engine is cool, wrap a thick cloth
around the cap and turn it slowly
counterclockwise to the first stop.
[SV17775(ALL)03/95]
3. Step back while the pressure releases.
[SV17780(ALL)03/95]
4. When you are sure that all the pressure has
been released, use the cloth to turn and
remove cap.
[SV17785(ALL)03/95]
5. Stand away from the radiator opening. Hot
steam may blow out or hot engine coolant
may even splash out.

Adding engine coolant to reservoir
[SV20075()08/95]
RWARNING
Be careful not to add engine coolant to
the windshield washer fluid reservoir. If
sprayed on the windshield, engine coolant
could make it difficult to see through the
windshield.
[SV20100()08/95]
When the engine is cool, add a 50/50 mixture of
engine coolant and water to the engine coolant
recovery reservoir - DO NOT ADD DIRECTLY
TO THE RADIATOR. Add straight water only in
an emergency, but you should replace it with a
50/50 mixture of coolant and distilled water as
soon as possible.
[SV20125()08/95]
Check the coolant level in the coolant recovery
reservoir the next few times you drive the
vehicle. If necessary, add enough of a 50/50
mixture of coolant and water to bring the liquid
level to the fill line on the reservoir.
[SV20150()08/95]
RWARNING
Never remove the coolant recovery cap
while the engine is running or hot.

Engine Coolant Drain and Flush
*
[SV20800(ALL)10/89]
To drain your vehicle's engine coolant:
*
[SV20900(ALL)03/94]
1. Turn off the engine and let it cool. Fully
depressurize the engine cooling system by
covering the radiator cap with a thick cloth
and turning it slowly counterclockwise to the
first stop. Step back while the pressure
releases.
*
[SV20950(ALL)05/90]
2. Remove the cap.
*
[SV21000(ALL)05/90]
3. Attach a small hose to the drain tube at the
bottom of the radiator.
*
[SV21200(ALL)05/90]
4. Let the engine coolant drain into a suitable
container. Disconnect the lower radiator hose
at the radiator connector and drain any
remaining engine coolant into a container.
*
[SV21225(ALL)05/94]
5. Reconnect the lower radiator hose and close
the radiator drain cock.
*
[SV21250(ALL)05/95]
Proper procedures for flushing the cooling
system can be found in theService Manual.

Engine coolant refill procedure
*
[SV21400(ALL)10/89]
After you have drained the engine cooling
system:
*
[SV21500(ALL)01/89]
1. Fill the radiator with a 50/50 mixture of the
specified engine coolant concentrate and
water. Allow several minutes for trapped air
to escape (bubble out) and for engine coolant
to flow through the radiator.
*
[SV21900(ALL)03/94]
2. Replace the radiator cap to its fully installed
position, then back off to the first stop. This
will prevent high pressure from building up
in the cooling system during this part of the
fill procedure.

290 [SV22000(ALL)03/91]3. Turn the heater (temperature and mode
selection) knobs to maximum heat positions
and operate the engine at fast idle
(approximately 2000 RPM) for three to four
minutes.
*
[SV22200(ALL)05/95]
4. Shut off the engine and allow the engine to
cool. Cover the radiator cap with a thick
cloth and cautiously remove it. Step back
while the pressure releases.
[SV22300(ALL)05/89]
5. Add the engine coolant mixture to a level
approximately 1 to 1 1/2 inches (38 mm)
below the filler neck seat.
[SV22400(ALL)05/89]
6. Reinstall the radiator cap fully and back off
to the first stop. Once again, turn the engine
at fast idle until the upper radiator hose is
warm and the thermostat is open.
[SV22550(ALL)05/89]
7. Finally, check the radiator and add more
engine coolant if needed, following the
procedures noted above. Reinstall the
radiator cap securely, when finished.
[SV22555(ALL)05/95]
8. If more engine coolant is necessary, remove
the small plug from the top of the engine
coolant recovery reservoir (not the large cap
of the windshield washer reservoir) and add
1.1 quarts (1 liter) of the 50/50 engine
coolant mixture. Replace the plug in its
original position.

[SV22565(ALL)08/95]
NOTE: Due to air being trapped in the 4.0L
engine cooling system, it is not
unusual to experiencea4to7ounce
(120 to 210 ml) coolant loss up to 7,500
miles (12,000 km) after initial system
fill.
