• Q: How to Remove and Install a Timing Chain on 2005 Chrysler 300?

  A: Before changing the timing chain, take off the negative battery cable and drain all the coolant from the system. Carefully remove the upper intake manifold, covers for the cylinder head, the crankshaft vibration damper and the timing chain cover. Put the crankshaft timing mark over the oil pump housing mark showing the position at 600 ATDC. Before turning the camshafts or crankshaft after removing the timing chain, make sure the crankshaft is in the correct position to avoid valve and piston problems. Remove the cap securing the chain tensioner retainer from the right head, remove the retainer and chain, take out the position sensor from the left cylinder head and remove the timing chain access plugs from each head. Unbolt the camshaft sprocket attaching bolts, as well as the camshaft damper if present and unbolt the left camshaft sprocket too. Uninstall the timing chain guide and its tensioner arm, then take out the secondary timing chain and crankshaft sprocket. Check each sprocket and all the chain guides for wear, replacing any that need to be replaced. Put in the right and left side short chain guides, then tighten the bolts to 28 Nm. Before you install the primary chain sprocket, put engine oil on the timing chain and guides. As you show it on the chain, check that the timing mark is between the two plated components. Decrease the mainchain size with the left side fixed tooth wheel using the opening through the left head cylinder, letting it rotate freely on the camshaft hub right now. Relax the left side camshaft sprocket carefully on the camshaft hub, make sure the timing link is in place with the crankshaft sprocket timing mark and only then place the primary chain on the water pump drive sprocket. Use the camshaft timing mark on the sprocket and bring the timing link from the timing chain into alignment with it. Ensure the chain timing links are lining up with the marks on all sprockets and after that, set up and tighten the left side lower chain guide and tensioner arm to 28 Nm. Examine the O-ring before putting in and tightening the chain guide access plugs to 20 Nm as needed. Use Special Tool 8186 to remove oil from the timing chain tensioner. Check Ball end goes into the shallow end and Tensioner may be slowly lowered till oil is visible. When using Special Tool 8186, insert the cylinder plunger into the lower end and press down until the tensioner returns to its original position. Double check that the tensioner is set properly, onto Special Tool 8186, without scraping the brass body against the nuts and replace the tensioner O-ring if you notice damage. Slide the reset chain tensioner into the right side of the cylinder head, add the retaining plate and fasten the bolts to a torque of 12 Nm. First, position the damper over the cylinder bank you began with, then place it over the cam hub and tighten the hub with a 3/8 square drive extension and breaker bar until the hub matches with the sprocket's screw holes. Also rotate the sprocket of the left camshaft in order and tighten its bolts to 28 Nm. Gently turn the engine clockwise if the timing chain needs it, then press the tensioner arm towards the tensioner to confirm that it has worked. Put on the camshaft position sensor and link the electrical connector and then the timing chain cover, crankshaft vibration damper, cylinder head covers and top intake manifold. Cool the engine, add coolant to the cooling system and then link the negative cable to the battery. There might be a brief noise from the engine after installing a reset tensioner, yet it will disappear shortly after it begins running.
