Repair Instructions for a 1998 Honda Prelude Timing Belt

The Honda Prelude is a sports coupe that Honda manufactured from 1978 to 2001. The 1998 model is available with several types four-cylinder, 2.2-liter engines, which have a single or double overhead camshaft. These engines use a timing belt to keep the rotation of the crankshaft and camshaft synchronized. The timing belt has a limited lifetime and its repair consists of replacing the timing belt at periodic intervals.

Instructions

    1

    Disconnect the cable from the negative battery terminal with a socket wrench. Turn the crankshaft clockwise to move the No. 1 cylinder to its top dead center position. Remove the covers for the valves and timing belt.

    2

    Fasten a bolt for the timing belt cover to the adjuster arm of the timing belt tensioner with a socket wrench. This will hold the adjuster arm in place temporarily. Loosen the adjuster nut for the timing belt by one turn and push the tensioner for the balancer belt away from the belt to reduce the tension on the belt.

    3

    Hold the tensioner for the balancer in place and tighten its adjusting nut with a socket wrench. Remove the balancer belt from its pulleys and detach the sprocket for the balancer belt from the crankshaft.

    4

    Loosen the lock bolt and adjusting nut on the timing belt tensioner with a socket wrench and push the tensioner to relieve the timing belt tension. Tighten the adjuster nut to hold the belt tensioner in place and remove the timing belt from the camshaft pulley.

    5

    Turn the crankshaft clockwise to align its timing pointer with the timing mark on the flywheel. Turn the camshaft pulley clockwise until the word "UP" is on top of the pulley.

    6

    Install the timing belt onto its pulleys and belt tensioner. Loosen the locking bolt on the timing belt tensioner with a socket wrench. Loosen the adjusting nut for the timing belt, then tighten it. Turn the crankshaft clockwise to move the timing belt forward by three teeth to place tension on the timing belt.

    7

    Loosen the adjusting nut for the timing belt with a torque wrench, then tighten it to 33 foot-pounds. Tighten the locking bolt for the timing belt tensioner and turn the crankshaft clockwise to align the timing marks. Place the sprocket for the balancer belt on the crankshaft and turn the pulley for the balancer belt so that its timing mark aligns with the notch on the oil pump.

    8

    Install the balancer belt onto its pulleys, ensuring that its timing marks remain aligned. Loosen the adjusting nut for the balancer belt tensioner slowly to place tension on the balancer belt.

    9

    Turn the crankshaft clockwise one turn to align the timing marks on the timing belt and tighten the adjusting nut to 33 foot-pounds with a torque wrench. Remove the bolt that is holding the timing belt tensioner in place. Install the covers for the timing belt and valves. Connect the cable for the negative battery terminal with a socket wrench.
