Engine coolant refill procedure
*
[MC14000(FM)01/96]
After you have drained the engine cooling
system:
*
[MC14050(FM)01/96]
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.
*
[MC14100(FM)01/96]
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.
*
[MC14150(FM)01/96]
3. Start and idle the engine until the thermostat
opens and the radiator upper hose becomes
warm.
*
[MC14200(FM)01/96]
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.
*
[MC14250(FM)01/96]
5. Finally, check the radiator and add more
engine coolant if needed, following the
procedures noted above. Reinstall the
radiator cap securely, when finished.
*
[MC14300(FM)01/96]
6. If more engine coolant is necessary, fill the
overflow reservoir to the appropriate level
marked on the bottle.

Power Steering Fluid
*
[MC18350(FM)01/96]
Check the level of the power steering fluid at
least twice a year (i.e., every Spring and Fall).
*
[MC18400(FM)01/96]
To check the level of your power steering fluid:
*
[MC18450(FM)04/96]
1. Start the engine and let it run until the
power steering fluid reaches normal
operating temperature. The power steering
fluid will be at the right temperature when
the engine coolant temperature gauge in the
instrument cluster is near the center of the
NORMAL operating temperature range.
*
[MC18500(FM)01/96]
2. While the engine idles, turn the steering
wheel back and forth several times. Make
sure that the cap assembly is installed at this
time.
*
[MC18550(F )01/96]
3. Turn the engine off.
%*
[MC18650(FM)01/96]
4. Check the fluid level on the dipstick (which
is highlighted in yellow in your vehicle). The
fluid level should be between the arrows in
the FULL HOT range, which is marked on
the side of the dipstick, opposite the side
marked FULL COLD. Do not add fluid if the
level is within the FULL HOT range.

[MC19060(FM)03/96]
6. When you are finished, put the dipstick back
in and make sure that it fits snugly.
*
[MC19070(FM)03/96]
If you check the power steering fluid when it is
cold, make sure that the fluid reaches the FULL
COLD range on the dipstick. The reading will
only be accurate if the fluid temperature is
approximately 50 to85ÊF (10 to 30ÊC).
[MC19100(F )05/96]
Use only MERCONHAutomatic Transmission
Fluid.
*
[MC19250(FM)01/96]
If the power steering fluid is low, do not drive
your vehicle for a long period of time before
adding fluid. This can damage the power
steering pump.
*
[MC19400(FM)01/96]
NOTE: Do not turn the steering wheel of your
vehicle with the engine off. It could
force power steering fluid out from the
reservoir cap or in extreme cases, it
could unseat the cap.

Fuel Economy
*
[MC36500(FM)01/96]
Fuel economy is an estimate of the efficiency of
your vehicle and can be calculated as Miles Per
Gallon (MPG) or Liters Per 100 Kilometers
(L/100K).
*
[MC36600(FM)01/96]
Do not calculate fuel economy during your
vehicle's break-in period. This would not be an
accurate estimate of how much fuel your vehicle
will normally use.
*
[MC36700(FM)01/96]
To calculate fuel economy:
*
[MC36800(FM)01/96]
1. Fill the tank completely and record the
initial odometer reading.
