The timing belt on the 1981 through 1986 1.6 Escort has a life expectancy of 60,000 miles before stretching to far for the tensioner to operate effectively. The engine has been identified as an interference engine in which a failure of the timing belt is most likely to cause major damage to the engine. Never turn the crankshaft with the timing belt off. This recommendation is based on the previous service history of this particular engine.
Tools Used: Set of ¼-inch sockets, ¼-inch ratchet, Set of ½-inch sockets, ½-inch air gun, Set of metric wrenches, Common screwdriver, ½-inch short extension, 2 foot torque bar, ½-inch torque wrench
Change Timing Belt
Remove the accessory belts and the timing cover. Remove the lower splash guard and the crankshaft pulley bolt. Remove the crankshaft pulley. Turn the crankshaft clockwise until the mark on the crankshaft sprocket is lined up with the mark on the block. The mark on the block is shaped like a V and is on a raised piece. Check the camshaft timing marks. The camshaft sprocket has a hole with a raised V in it--line this up with the hole in the top of the block.
Loosen the tensioner bolts and push the tensioner away from the belt then lightly tighten the bolts to hold the tensioner out of the way. Remove the timing belt. Make sure the timing marks align as described in Step 1. Install the timing belt starting from the crankshaft sprocket, working counter clockwise. Keep all the tension on the right side away from the tensioner.
Loosen the tensioner bolts and allow the tensioner to operate then torque the bolts to 20 foot pounds of torque. Install the crankshaft pulley and the bolt. Torque the crankshaft bolt to 90 foot pounds of torque.
Crank the engine for 30 seconds. Turn the crankshaft clockwise until the alignment marks line up. Using the appropriate socket and the long torque handle place the socket and handle on the crankshaft bolt and put the handle on the driver's side on the floor to hold the crankshaft from moving.
Torque the camshaft sprocket bolt counterclockwise and torque to 32-foot pounds of torque, which allows the tensioner to take up the additional slack. Torque the tensioner bolts to 20-foot pounds of torque. Rotate engine two more times and check the timing marks. Install all components in reverse order of removal.
