Removal
NOTE:
. Replace the timing belt at 105,000 miles (168.000 km)
according to the maintenance schedule (normal con-
ditions/severe conditions).
lf the vehicle is regularly driven in one or more of the
followlng conditions, replace the timing belt at 60.000
miles (U.S.A.) 100,000 km {Canada).
.In very high temperatures (over 110'F.43'C)
. In very low temperatures (under -20'F, -29"C)'
! Turn the crankshaft pulley so the No. 1 piston is at
top dead center (TDC) before removing the belt (see
page 6'21).
. Inspect the water pump before installing the timing
belt {see Page 10-14).
1. Remove the splash shield (see page 5-7).
2. Loosen the mounting bolt and lock bolt. then remove
the power steering (P/S) pump belt and pump
