Timing Belt

WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: If camshafts have moved from the timing marks, always rotate camshaft towards the direction nearest to the timing marks (DO NOT TURN CAMSHAFTS A FULL REVOLUTION OR DAMAGE to valves and/or pistons could result).

  1. Align the crankshaft sprocket (10) with the TDC mark (9) on oil pump cover. See Fig 1.
  2. Align the camshaft sprockets (2, 7) timing reference marks (1, 8) with the marks on the rear cover.
  3. Install the timing belt starting at the crankshaft sprocket (10) going in a counterclockwise direction. Install the belt around the last sprocket. Maintain tension on the belt as it is positioned around the tensioner pulley (11).
    NOTE: If the camshaft gears have been removed it is only necessary to have the camshaft gear retaining bolts installed to a snug torque at this time.
  4. Holding the tensioner pulley (11) against the belt, install the tensioner into the housing and tighten to 28 N.m (250 in. lbs.). Each camshaft sprocket mark should remain aligned the cover marks.
  5. When tensioner is in place pull retaining pin to allow the tensioner to extend to the pulley bracket.
  6. Rotate crankshaft sprocket 2 revolutions and check the timing marks on the camshafts and crankshaft. The marks should line up within their respective locations. If marks do not line up, repeat procedure.
    NOTE: If camshaft gears have been removed and timing is correct, counter-hold and tighten the camshaft gears to final torque specification. (Refer to ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND SPROCKETS - INSTALLATION) .
  7. Install the front timing belt cover. (Refer to ENGINE/VALVE TIMING/TIMING BELT/CHAIN COVER(S) - INSTALLATION)  .
  8. Tighten the rocker arm assemblies and install the cylinder head covers. (Refer to ENGINE/CYLINDER HEAD/ROCKER ARM/ADJUSTER ASSY - INSTALLATION) .
  9. Connect negative battery cable.
