ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
„ Hose and connections
„Hose and connectionsYour vehicle employs an electric cooling fan which is
thermostatically controlled to operate when the engine
coolant reaches a s pecific temperature.
If the radiator cooling f an does not operate even when
the engine coolant temperature gauge exceeds the
normal operating range, the cooling fan circuit may be
defective. Check the fuse and replace it if necessary.
If the fuse is not blown, have the cooling system
checked by your SUBARU dealer.
If frequent addition of coolant is necessary, there may
be a leak in th e engine cooling syst em. It is recom-
mended that the cooling system and connections be
checked for leaks, damage, or looseness. „

TChecking the coolant level

2) “LOW” level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside of the reser-
voir while the engine is cool.
2. If the level is close to or lower than the “LOW” level
mark, add coolant up to the “FULL” level mark. If the
reserve tank is empty, remove the radiator cap and re-
fill as required.

3. After refilling the reserve tank and the radiator, re-
install the caps and check that the rubber gaskets in-
side the radiator cap are in the proper position.
y Be careful not to spill engine coolant when
adding it. If coolant touches the exhaust pipe, it
may cause a bad smell, smoke, and/or a fire. If
engine coolant gets on the exhaust pipe, be
sure to wipe it off.y Do not splash the engine coolant over paint-
ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
T Changing the coolant
Always add genuine SUBARU cooling system condi-
tioner whenever the coolant is replaced.
Change the engine coolant and add genuine SUBARU cooling system cond itioner using the following proce-
dures according to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
1. Remove the under cover.

2. Place a proper container under the drain plug and
loosen the drain plug.
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 is re-
moved. 3. Loosen the radiator cap to drain the coolant from
the radiator. Then drain the coolant from the reserve
tank. Tighten the drain plug securely.
NOTE (Turbo models)
The cap (without tabs) on top of the radiator does
not need to be removed. To add coolant, remove
the cap (with tabs) on th
e coolant tank on top of
the engine.

4. Slowly pour the coolant and fill up to just below the
filler neck, allowing enough room to add genuine
SUBARU cooling system cond itioner in the radiator.
Add genuine SUBARU coolin g system conditioner un-
til the coolant level reaches the filler neck. Do not pour
the coolant too quickly, as this may lead to insufficient
air bleeding and trapped air in the system.

“FULL” level mark. 1) Rubber gaskets
6. Put the radiator cap back on and tighten firmly. At
this time, make sure that the rubber gasket in the radi-
ator cap is correctly in place.
7. Start and run the engine for more than five minutes
at 2,000 to 3,000 rpm.
8. Stop the engine and wait until the coolant cools
down (122 to 140 °F [50 to 60 °C]). If there is any loss
of coolant, add coolant to the radiator’s filler neck and
to the reserve tank’s “FULL” level.
9. Put the radiator cap and reservoir cap back on and
tighten firmly.

Air cleaner elementAir cleaner element
Do not operate the engine with the air cleaner
element removed. The air cleaner element not
only filters intake air but also stops flames if the
engine backfires. If the air cleaner element is
not installed when the engine backfires, you
could be burned.
The air cleaner element func tions as a filter screen.
When the element is perforated or removed, engine
wear will be excessive and engine life shortened.
The air cleaner element is a viscous type. It is unnec-
essary to clean or wash the element. „ Replacing the air cleaner element

Replace the air cleaner element according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet”. Under extremely dusty conditions, re-
place it more frequently. It is recommended that you
always use genuine SUBARU parts.

„ Fluid levelThe 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.

Booster
If the brake booster does not operate as described in
the following, have it checked by your SUBARU deal-er.
1. With the engine off, depress the brake pedal sever-
al times, applying the same pedal force each time. The
distance the pedal travels should not vary.
2. With the brake pedal depressed, start the engine.
The pedal should move slightly down to the floor.
3. With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds. The
pedal height should not change.
4. Start the engine again and run for approximately
one minute then turn it off. Depress the brake pedal
several times to check the brake booster. The brake
booster operates properly if the pedal stroke decreas-
es with each depression.
