1.Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value:
When belt tension is inspectedor readjusted
When new belt is installed
/ 9 - 11 mm (.35 - .43 in.)
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

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

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.
