2000 Mitsubishi Eclipse Change Timing Belt

From WikituneUp - The Free Service Manual
Jump to: navigation, search

The manufacturer recommends that the timing belt on the 1997 through 2000 3.0 Mitsubishi Eclipse be replaced at 60,000-mile intervals. This is taking into account the previous service history on the engine. This engine is considered an interference engine in which a timing belt failure would most likely result in major engine damage, therefore make sure not to turn the crankshaft with the timing belt removed.

Tools Used[edit]

Set of ¼-inch sockets
¼-inch ratchet
Set of ½-inch sockets
½-inch air gun
Common screwdriver
Special tool # MD990767 pulley holder
Special tool # MD998715 pulley holding pins
Special tool # MD998767 tensioner tool
Cotter pins

Change Timing Belt[edit]

  • Remove the accessory drive belt tensioner and accessory drive belts. Remove the alternator and the air conditioning compressor but leave the hoses connected. Move the air conditioning compressor out of the way. Remove the power steering pump (again, leave the hoses connected). Move the power steering pump out of the way. Remove the upper timing belt covers.
  • Remove the crankshaft pulley bolt using special tool #MD990767 (pulley holder). Remove the crank pulley and the lower timing belt cover. Using the special tool, turn the crankshaft clockwise until the mark on the crankshaft sprocket lines up with the arrow on the block. Check the camshaft sprockets to be sure that the marks on the sprockets align with the marks on the rear timing belt covers.
  • Loosen the tensioner pulley bolt and allow tensioner to move away from the belt. Lightly tighten the bolt to hold the tensioner out of the way. Remove the timing belt, the tensioner bolts and the tensioner. Make sure that the rod in the tensioner extends out to 0.048 inches. If not, replace the tensioner.
  • Insert the auto tensioner into a vise and compress the rod back into the tensioner body. Insert a cotter pin through the holes in the body and rod to hold the rod from extending. Install the auto tensioner and torque the bolts to 17 ft.-lbs. of torque.
  • Make sure the timing marks line up. Install the timing belt in a counter clockwise direction making sure that the belt is tight on the nontensioned side. Loosen the tensioner bolt and using the special tool (#MD998767) turn the tensioner pulley against the belt and loosely tighten the bolt.
  • Using the special tool, turn the crankshaft a quarter turn counterclockwise and then turn it back a quarter turn and line up the timing marks. Loosen the tensioner bolt and using the special tool and a torque wrench apply 3.3 ft.-lbs. of torque to the belt. While maintaining the torque, tighten the tensioner bolt to 35 ft.-lbs. of torque. Remove the cotter pin from the auto tensioner and allow it to extend.
  • Using the special tool, turn the crankshaft clockwise two more turns and recheck the timing marks. If they line up, install the components in the reverse order of removal and torque the crankshaft pulley bolt to 134 ft.-lbs. of torque.
