Camshaft Sprockets
WARNING: This page is about a different car, the 2010 Dodge Charger and 2010 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
The 3.5L engine is NOT a free-wheeling design. Therefore, care should be taken not to rotate the camshafts or crankshaft with the timing belt removed.
CAUTION:
The camshaft sprockets are keyed and not interchangeable from side to side because of the camshaft position sensor pick-up.
- Install the right camshaft sprocket onto the camshaft.
- Install a NEW sprocket attaching bolt into place. The 213 mm (8 3/8 in.) bolt is to be installed into the right camshaft and the 255 mm (10 in.) bolt is to be installed into the left camshaft.
- Hold the right camshaft sprocket with a 36 mm (1 7/16 in.) box end wrench so that the timing mark (2) does not move while tightening the retaining bolt. Tighten the bolt to 102 N.m (75 ft. lbs.) +90° turn.
- Install the left camshaft sprocket onto the camshaft.
- Install a NEW sprocket attaching bolt into place. The 255 mm (10 in.) bolt is to be installed into the left camshaft and the 213 mm (8 3/8 in.) bolt is to be installed into the right camshaft.
- Hold the left camshaft sprocket with a 36 mm (1 7/16 in.) box end wrench so that the timing mark (1) does not move while tightening the retaining bolt. Tighten the bolt to 102 N.m (75 ft. lbs.) +90° turn.
- Tighten the upper radiator mounting bolts (1) and (2) to 12 N.m (106 in. lbs.).
- Install the grill closure panels (1).
- Install the timing belt and tensioner. See Engine/Valve Timing/BELT and SPROCKETS, Timing - Installation .
- Install the front timing belt cover. See Engine/Valve Timing/COVER(S), Engine Timing - Installation .
- Connect the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
- Fill cooling system. Refer to Cooling - Standard Procedure .
- Operate engine until it reaches normal operating temperature. Check cooling system for correct fluid level. Refer to Cooling - Standard Procedure
.NOTE: The Cam/Crank Variation Relearn procedure must be performed anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components. Refer to DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
