1.Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.

When belt tension is inspectedor readjusted
When new belt is installed

I
’ 7 - 8.5 mm (.28 - .33 in.)
2.If the deflection is out of the standard values, adjust the belt
tension using the following procedure.
(1) Loosen the tension pulley’s securing bolts A and
B.(2) Mount the extension bar on the tension pulley.
(3) While increasing the tension of the V-belt with the
extension bar, retighten the tension pulley’s securing
bolts A and B in the order mentioned.
FLUID LEVEL CHECKM37FlAJ
1.Park the vehicle on a flat, level surface, start the engine, and
then turn the steering wheel several times to raise the
temperature of the fluid to approximately 50
- 60°C (122 -
140°F).
2.With the engine running, turn the wheel all the way to the
left and right several times.
3.Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTM37FJAL1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the oil
into a container.
4. Disconnect the high-tension cable, and then while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times to drain
all of the fluid.
Caution
Be careful not to position the high-tension cable nearthe carburetor or the delivery pipe.
5.Connect the return hoses securely, and then secure it with
the clip.
6.Fill the oil reservoir with the specified fluid up to the lower
position of the filter, and then bleed the air.
Specified fluid:MITSUBISHI PLUS ATF/Automatic
transmission fluid “DEXRON” or
“DEXRON II”

BLEEDINGM37FKAl
1.Jack up the front wheels and support them by using a floor
stand.
2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and to the
right several times.
4. Disconnect the high-tension cable, and then, while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times (for 15
to 20 seconds).
Caution1. During air bleeding, replenish the fluid supply so
that the level never falls below the lower position ofthe filter.
2. If air bleeding is done while engine is running, the
air will be broken up and absorbed into the fluid; besure to do the bleeding only while cranking.
5. Connect the ignition cable, and then start the engine
(idling).
6.Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7.Confirm that the fluid is not milky, and that the level is up to
the specified position on the level gauge.
8. Confirm that there is very little change in the fluid level
when the steering wheel is turned left and right.
Fluid level change:wlthln 5 mm 1.2 in.)I
9.Check whether or not the change in the fluid level is within
5 mm
(.2 in.) when the engine is stopped and when it is
Irunning.
Caution
While enginerunningWhile enginestopped13UOl1. If the change of the fluid level is 5 mm
I.2 in.) or
more, the air has not been completely bled from thesystem, and thus must be bled completely.
2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be
abnormal noises from the pump and the flow-
control valve, and this condition could cause a
lessening of the life of the pump, etc.
