Checking and Adding Engine Oil
*
[SV13800( ALL)03/95]
Since the proper amount of engine oil is
important for safe engine operation, check the oil
using the dipstick each time you put fuel in
your vehicle. Remember the engine must be off,
the oil must be warm and the vehicle must be
parked on level ground.
*

Checking the engine oil level:
*
[SV14000( ALL)02/95]
1. Turn the engine off after it has warmed up
and allow a few minutes for the engine oil
to drain back into the oil pan.
*
[SV14050(B F )03/95]
2. Set the parking brake, making sure that the

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.
*
[SV22100( ALL)10/89]
3. Start and idle the engine until the thermostat
opens and the radiator upper hose becomes
warm.
*
[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.
*
[SV22500( ALL)10/89]
5. Finally, check the radiator and add more
engine coolant if needed, following the
procedures noted above. Reinstall the
radiator cap securely, when finished.
*
[SV22525( ALL)05/90]
6. If more engine coolant is necessary, fill the
overflow reservoir to the appropriate level
marked on the bottle.

operating temperature if outside temperatures
are above50ÊF (10ÊC).
*
[SV33801( ALL)01/95]
NOTE: If the vehicle has been operated for an
extended period at high speeds or in
city traffic during hot weather, or
