Inspection
Remove the cylinder head cover.
lnspect the timing belt for c.acks and oil or coolant
soaking. Replace the belt if it is oil or coolant
soaked. Remove any oil or solvent that gets on the
belt.
lnspect thisarea for wear.
After inspecting, retorque the crankshaft pulley bolt
to 177 N.m (18.0 kgnm, 130 lbf.ft).
Install the cylinder head cover (see page 6-32).
3.
Tension Adjustment
NOTE:
. Always adjust the timing belt tension with the engine
coto.
. Always rotate the crankshaft counterclockwise when
viewed from the pulley side. Rotating it clockwise
may result in improper adiustment of the belt ten-
sion.
'1. Remove the cylinder head cover
2. Set the No. 1 piston at TDC (see page.6-12).
3. Rotate the crankshaft five or six revolutions to set
the belt.

Timing Belt
Removal
Replace the timing belt at 105,000 miles (168,000 km)
according to the maintenance schedule {normal condi-
tions/severe conditions). lf the vehicle is regularly driven
in either of the following conditions, replace the timing
belt at 60,000 miles (U.S.A.l 100.000 km (Canada).
- ln very high temperatures (over 110'F, 43"C).- In very low temperatures (under -20"F. -29"C).
Turn the crankshaft pu\ley so the No. 1 piston is at
top dead center (TDC).
Remove the guard bar and splash shield (see page
5-7 ).
Loosen the mounting bolt and lock bolt. then remove
the power steering (P/S) pump belt.
