5. Wipe the seating surface of the drain plug with a
clean cloth and tighten it securely with a new seal-ing washer after the oil has completely drained out.

1) Oil filter
6. Remove the oil filter with an oil filter wrench.
7. Before installing a new oil filter, apply a thin coat of engine oil to the seal.
8. Clean the rubber seal seating area of the lower
crank case and install the oil filter by hand turning.
Be careful not to twist or damage the seal.
9. Tighten it approximately two-thirds of a turn afterthe seal makes contact with the lower crank case.
CAUTION
Never over tighten the oil filter because that can result in an oil leak.
10. Pour the specified amount of engine oil throughthe filler neck.
Oil capacity: Non-turbo models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
Turbo models: 4.8 US qt (4.5 liters, 4.0 Imp qt)
11. Start the engine and make sure that no oil leaks
appear around the filter ’s rubber seal.
12. Run the engine until it reaches the normal oper-
ating temperature. Then stop the engine and wait a
few minutes to allow the oil drain back. Check the oil
level again and if necessary, add more engine oil. Recommended grade and viscosity
CAUTION
Use only engine oil with the recommended
grade and viscosity.

2) “LOW” level mark
WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has cooled
down completely. Since the coolant is under pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap isremoved.
4. Slowly pour the coolant and fill to the radiator fill-
er neck and to the reserve tank ’s “FULL” level mark.
Do not pour the coolant too quickly, as this may lead to insufficient air bleeding and trapped air in thesystem.

2. Pull out the dipstick, wipe it clean, and insert it again.
3. Pull out the dipstick again and check the oil level
on it. If it is below the lower level, add oil through thedipstick hole to bring the level up to the upper level. Recommended grade and viscosity
Each oil manufacturer has its own base oils and ad-
ditives. Never use different brands together.

Temperature 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 differ-ent scales for checking the level of hot fluid andcold fluid on the dipstick.
Though the fluid level can be checked without
warming up the fluid on the “COLD” range, we rec-
ommend checking the fluid level when the fluid is at
operating temperature.
Checking the fluid level when the fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise the tem-
perature of the transmission fluid up to normal oper-
ating temperature; 140 to 176 °F (60 to 80 °C) is nor-
mal.
2. Park the vehicle on a level surface and set theparking brake.
3. First shift the selector lever in each position. Then shift it in the “P” position, and run the engine at id-
ling speed.

Checking the gear oil level
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
required when checking the oil level.

Remove the plug from the filler hole and check the oil level. The oil level should be kept even with thebottom of the filler hole. If the oil level is below the
bottom edge of the hole, add oil through the filler
hole to raise the level.
CAUTION
If the vehicle requires frequent refilling, there
may be an oil leak. If you suspect a problem,
have the vehicle checked at your SUBARU
dealer.

Power steering fluid Checking the fluid level
The power steering fluid expands greatly as its tem-
perature rises; the fluid level differs according to
fluid temperature. Therefore, the reservoir tank has
two different checking ranges for hot and coldfluids.
Check the power steering fluid level monthly.
1. Park the vehicle on a level surface, and stop theengine.
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run: Check that the oil level is between “HOT MIN ” and
“ HOT MAX ” on the surface of the reservoir tank.
When the fluid is cool before the vehicle is run: Check that the oil level is between “COLD MIN ” and
“ COLD MAX ” on the surface of the reservoir tank.
3. If the fluid level is lower than the applicable “MIN”
line, add the recommended fluid as necessary tobring the level between the “MIN” and “MAX” line.
