Removal & Installation



3.5L & 4.0L Engines
  1. Before servicing the vehicle, refer to the Precautions section.
  2.  

Use care when servicing a timing belt. Valve timing is absolutely critical to engine performance. If the valve timing marks on all drive sprockets are not properly aligned, engine damage will result. If only the belt and tensioner are being serviced, do not loosen the camshaft drive sprockets unless they are to be replaced. The sprockets have oversized openings and can be rotated several degrees in each direction on their shafts. This means the sprockets must be re-timed, requiring some special tools.


CAUTION
Fuel injection systems remain under pressure, even after the engine has been turned off. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

  1. Remove or disconnect the following:

    Negative battery cable
     
    Cylinder head covers
     
    Accessory drive belts
     
    Drive belt tensioner
     
    Power steering pump bolts and position the pump aside
     
    Crankshaft damper with a quality puller tool gripping the inside of the pulley
     
    Lower front timing belt cover retainers
