MAINTENANCE SERVICE
1. FUEL SYSTEM (Tank, Lines, Connections and
Fuel Tank Filler Tube Cap) (Check for leaks)/2.
FUEL HOSES (Check for leaks or
damagekOOSnOB.
1.Check for damage or leakage in the fuel lines and con-
nections and looseness of the fuel tank filler tube cap.
2. Inspect the surface of fuel hoses for heat and mecha-
nicall damage. Hard and brittle rubber, cracking, check-
ing, tears, cuts, abrasions and excessive swelling
indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is exposed by cracks and abrasions in the fuel system, the hoses
should be changed.
3. AIR CLEANER ELEMENT (Replace)
MMlSAKH
The air cleaner element will become dirty and loaded with dust during use, and the filtering effect will be substantiallyreduced. Replace it with a new one.
(1) Loosen the clamp coupling the air intake hose and the air cleaner cover, and separate the hose.
(2) Disconnect the volume air flow sensor connectors.
(3) Unclamp the air cleaner cover clip.
(4) Lifting the air intake hose, remove the air cleaner cover.

O.AUTOMATIC
TRANSAXLE
Inspect fluid levelMOOSSDA
1. Drive until the fluid temperature reaches the usual ternperature
[70-80°C (160- 18O”F)I.
2. Plaice vehicle on level floor.
3.Move selector lever sequentially to every position to fill
torque converter and hydraulic circuit with fluid, then place lever in “N” Neutral position. This operation is
necessary to be sure that fluid level check is accurate.
4. Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the
condition of the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
l If there is a noticeably great amount of metal particles in the fluid.
5.Chleck to see if fluid level is in “HOT” range on dipstick.
If fluid level is low, add ATF until level reaches “HOT”
range.
LO\N fluid level can cause a variety of conditions
because it allows pump to take in air along with fluid. Air
trapped in hydraulic circuit forms bubbles which make
fluid spongy. Therefore, pressures will be erratic. Improper filling can also raise fluid level too high. When
transaxle has too much fluid, gears churn up foam and cause same conditions which occur with low fluid level,
resulting in accelerated deterioration of ATF.In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,
and servo operation. Foaming can also result in fluid escaping from transaxle vent where it may be mistaken
for a leak.
6. Be sure to examine fluid on dipstick closely. Chaqge
fluid
Drain
tlhe fluid and check whether there is any evidence of
contamination. Replenish with new fluid after the cause of any contamina-
tion
has been corrected.
(1) Rernove drain plugs to let fluid drain.
(2) Rernove the oil pan.
(3) Check the oil filter for clogging and damage and replace
if necessary.
(4) Clean the inside of oil pan and 5 magnets.
(5) Attach the five magnets to the concave part of the oil
pan.
1 TSB Revision
(6) Clean both gasket surfaces of transaxle case and oil
pan.
(7) Install oil pan with new gasket and tighten oil pan bolts
to
IO-I 2 Nm (7.5-8.5 ftlbs.)
(8) Tighten drain plug with gasket to 30-35 Nm (22-25 ft.lbs.).
(9) Supply 4
dm3 (4.23 qts.) of specified ATF into case
through dipstick hole. [Total quantity of ATF required is 6.1
dm3 (6.45 qts.).
Actually however, approx. 4.5 dm3 (4.76 qts.) of fluid
car1 be replaced because rest of fluid remains in torque converter.]
