Removal
NOTE:
. Replace the timing belt at 105,000 mites (168,000 km)according to the maintenance schedule (normal con-ditions/severe conditions).
lf the vehicle is regularly driven in one or more of thefollowing conditions, replace the timing belt at 60,OOOmiles (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 attop dead center (TDC) before removing the belt (seepage 6-57).
. Inspect the water pump before installing the timingbelt {see page 10-14).
