Camshaft Sprockets - Installation
CAMSHAFT SPROCKETS
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.
1. Install the right camshaft sprocket onto the camshaft.
2. 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.
3. 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 Nm (75 ft. lbs.) +90° turn.
