Thirty tens, make sure not to push the
Timing Chain so that it turns separately from the camshafts or crankshaft, to keep parts like the valves or pistons safe. Choose the Wedge Lock Tool 8379 for camshaft, cam sprocket or timing chain work, so you won't have to take off the timing chain cover because of an overextended hydraulic tensioner ratchet. Remove the cylinder head cover, then turn the engine so that the camshaft sprocket mark on Cyl. No. 1 is pointing up. Make sure to apply one link mark on each side of the V6 mark on the camshaft sprocket, to use as reference during installation. Rotate the camshaft sprocket retaining bolt so it is loose, but still right against the sprocket. Tighten the tensioners for the timing chain before removing the camshaft sprockets so you don't have to remove the timing chain cover to reset them. Align the tool so it is between the strands of the timing chain and then tap away at it, helping the chain get trapped against the tensioner arm and guide. After that, take out the
Camshaft Position Sensor, grasp the camshaft with 8428 and remove the camshaft sprocket bolt and sprocket while holding the camshaft. Turn each of the camshaft bearing cap bolts backward a little at a time, half a turn, until all the load is removed. Also, make sure not to hit or damage the bearing caps. Keep in mind that, as soon as the camshaft is removed, the
Rocker Arms might drop into the cylinder head, so you need to mark them before taking out the camshaft caps and the camshaft.
