GENERAL -Maintenance Service
(1O)Star-t engine and allow to idle for at least two minutes.
Then, with parking brake on, move selector
fever
momentarily to each position, ending in “N” Neutral
position.
(11)Add sufficient ATF to bring fluid level to lower mark.
Recheck fluid level after transaxle is at normal Operating
temperature. Fluid level should be between upper and lower marks of
“HOT” range, Insert dipstick fully to prevent dirt from
entering transaxle.

COOLANT (Change)MOOSEEAC
Check the cooling system parts, such as radiator, heater,
and oil cooler hoses, thermostat and connections for
leakage and damage.
CHANGE COOLANT
1. Remove the radiator cap.
2. Loosen the drain plug to drain the coolant.
3. Drain the coolant from the reserve tank.
4. After draining the coolant, tighten the drain plug securely.
5.Supply the coolant into the radiator until it is filled up to
its filler neck.
6. Supply the coolant into the reserve tank.
7. After warming the engine until the thermostat opens, remove the radiator cap and check the coolant level.
8.Supply the coolant into the radiator until it is filled up to
its filler neck, and install the radiator cap securely.
9.Fill the reserve tank with coolant up to the “FULL” line.

Check for fluid contamination and wear. Replace complete
set of pads if defective.
Caution
The pads for the right and left wheels should be
reDlaced at the same time. Never “split” or intermix
brkke pad sets.
All four pads must be replace as a complete set.
Thickness of lining (A)
Limit: 2.0 mm (.08 in.)
13.REAR DRUM BRAKE LININGS AND REAR
WHEEL CYLINDERS (Inspect for wear and
leaks)MOOSBGB
1. Remove the brake drum and check the thickness of brake shoe lining for wear. Check the automatic brake
adjusting system by hand to see if it operates smoothly.
Also see if the gears are in proper mesh with each
other. To assure smooth functioning, apply a very thin
coat of multipurpose grease to the friction surface of
adjuster and link shaft.

COOLING -Service Adjustment Procedures T210863
SERVICE ADJUSTMENT PROCEDUl$t&
ENGINE COOLANT LEAK CHECK
1. Loosen radiator cap.
2. Confirm that the engine coolant level is up to the filler
neck.
3. Install a radiator cap tester to the radiator filler neck and
apply 160
kPa (23 psi) pressure. Hold pressure for. two
minutes, while checking for leakage from the radiator, hose or connections.
Caution
Be sure to completely clean away any moisture from
the places checked. When the tester is removed, be careful not to spill anyengine coolant from it.
Be careful, when installing and removing the tester
and when testing, not to deform the filler neck of the
radiator.
4.If there is leakage, repair or replace the appropriate part.
RADIATOR CAP PRESSURE TEST
MlOFBAA
1.Use a special tool to attach the cap to the tester.
2.Increase the pressure until the indicator of the gage stops
moving.
Limit: 65
kPa (9.2 psi)
Standard value:
75- 105 kPa (1 1 - 15 psi)
3.Replace the radiator cap if the reading does not remain at
or above the limit.
NOTE
Be sure that the cap is clean before testing, since rust or
other foreign material on the cap seal will cause an im-
proper indication.
