It's necessary to secure the 3.5L engine against independent rotation because this is not a freewheeling motor; make sure the valve train rocker assemblies are removed before attempting any
Crankshaft or
Camshaft rotation. Rotate the camshafts according to their timing marks and go no further than half a revolution so you do not harm the valves or pistons. Line up the crankshaft sprocket (10) with the TDC mark (9) on the oil pump cover and bring the camshaft sprocket (2) timing reference mark (1) into contact with the mark on the rear cover. Put the timing belt around the crankshaft sprocket (10) in the opposite of clockwise motion as you begin, stretching the belt as it is positioned above the tensioner pulley (11). Compress the companion plunger within the tensioner and add a locking pin before returning it to the installation site. While holding the pulley with one hand, attach the reset (pinned)
Timing Belt Tensioner (2) to the housing with both hands using the 28 Nm (250 in. lbs.) torque wrench, then install them with the attaching bolts. As soon as the tensioner (12) is in position, take out the retaining pin to extend it toward the pulley bracket. Turn the crankshaft sprocket (10) two revolutions and look at the timing marks on both the camshafts and the crankshaft; if the marks do not match, start again. Set the front timing belt cover into place, join the negative
Battery Cable and tighten the bolt to 5 Nm (45 in. lbs.) after installation. Fully fill the radiator with fluid, run the engine and monitor the fluid level inside the cooling system throughout. Whenever the
Flywheel, valvetrain, camshaft or crankshaft sensors are replaced, the Cam/Crank Variation Relearn method is necessary.
