Drive belts
The alternator, power steering pump, and air condi-
tioner compressor depend on drive belts. Satisfactory
performance requires that belt tension be correct.

To check belt tension, place a straightedge (ruler)
across two adjacent pulleys and apply a force of 22 lbs
(98 N, 10 kg) midway between the pulleys by using a
spring scale. Belt deflection should be the amount
specified.Manual transmission oil „ Checking the oil level

stick hole to bring the level up to the upper level. „ Recommended grade and viscosity

Automatic transmission fluid „Checking the fluid level
The automatic transmission fluid expands largely as
its temperature rises; the fluid level differs according to
fluid temperature. Therefore, there are two different
scales for checking the level of hot fluid and cold fluid
on the dipstick.
Though the fluid level can be checked without warm-
ing up the fluid on the “COLD” range, we recommend
checking the fluid level when the fluid is at operating
temperature. T Checking the fluid level when the fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise the temper-
ature of the transmission fluid up to normal operating
temperature; 158 to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and set the park-
ing brake.
3. First shift the selector lever in each position. Then
shift it in the “P” position, and run the engine at idling
speed.-30 -20 -10 0 10 20 30 40

4. Pull out the dipstick and check the fluid level on the
gauge. If it is below the lower level on the “HOT”
range, add the recommended automatic transmission
fluid up to the upper level. T Checking the fluid level when the fluid is cold
When the fluid level has to be checked without time to
warm up the automatic transmission, check to see that
the fluid level is between the lower level and upper lev-
el on the “COLD” range. If it is below that range, add fluid up to the upper level. Be careful not to overfill. „

Rear differential gear oil „Checking the gear oil level
If the vehicle requires frequent refilling, there
may be an oil leak. If you suspect a problem,
have the vehicle checked at your SUBARU deal-
er.
Your vehicle may be equipped with a rear differential
protector. The differential protector provides protec-
tion to the rear differential assembly during off-road
use. Removal of the rear differential protector is not re-
quired when checking the oil level.
