• Q: How to Service and Repair a Timing Chain and Sprockets on 2000 Chrysler Concorde?

  A: Before working on the timing chain and sprockets, take off the upper intake manifold, cylinder head covers, crankshaft damper and timing chain cover. Turn the crankshaft while aligning timing marks, so the valves and pistons are not damaged. Make sure the crankshaft timing mark touches the oil pump housing mark that is at 60° At the ATDC of the first cylinder. If the timing chain is out and the cylinder heads are still placed, do not turn either the camshafts or crankshaft without locating the proper crankshaft rotation. Take out the timing chain tensioner from the right head, the camshaft position sensor and the cover at the left. Unscrew both camshaft sprockets and remove the camshaft damper, then the three nuts on the left side camshaft sprocket and the chain guide and tensioner arm on the bottom. Check over all sprockets and chain guides and replace any parts that are too worn. If you remove both chain guides, put the left and right versions back into place, tightening their attaching bolts with 28 Nm (250 in. lbs.). Ensure that the crankshaft timing mark is aligned with the one on the oil pump housing and put some engine oil on the timing chain and its guides prior to installation. Lift the chain into place on the bicycle, making sure the primary sprocket timing aligns between the two large metal links, then drop the left side chain sprocket through the cylinder head on the left. Over the camshaft hub, only loosely fit the left side camshaft sprocket, matching the timing link on the camshaft to the crankshaft sprocket timing index. Insert the primary chain onto the water pump sprocket and place the camshaft timing mark so it matches the link on the chain while loosely placing the camshaft connecting sprocket on top of the camshaft hub. Carefully confirm that all plated links of the chain are aligned with the timing marks on all the sprockets, then install the left side lower chain guide. After that, tighten the tensioner arm bolts to 28 Nm (250 in. lbs.). Be sure the oil ring on the chain guide access plug is clean before you install and tighten the plug to 20 Nm (15 ft. lbs.) when installing the engine. Place the end of the check ball into the shallow side of Special Tool 8186 and gently press the tensioner until oil comes out. Push the cylinder plunger on Special Tool 8186 downward, as far as possible, to set the timing chain tensioner. Reset the tensioner so that Special Tool 8186 is holding it right against its top edge, to keep the tensioner from getting stuck. Set the reset chain tensioner into the right side of the cylinder head, place the tensioner retaining plate and tighten all screws to 12 Nm (105 in. lbs.). First, put the 3/8" square drive extension on the breaker bar into the inline cylinder bank's intake camshaft drive hub, rotating the camshaft until everything lines up. Place the sprocket attaching bolts and tighten them to 28 Nm (250 in. lbs.). Fit a 3/8" square drive extension onto the end of a breaker bar, push it into the intake camshaft drive hub on the left side and turn it clockwise until all the sprocket attaching bolts can be installed. Afterward, tighten them evenly to 28 Nm (250 in. lbs.). Turn the engine over slightly to the right if too much slack is present. To be sure the timing chain tensioner is armed, use a flat pry tool to lightly pry its arm towards the tensioner and then open and close it before checking it is armed. After that, install the timing chain cover, crankshaft damper, cylinder head covers, camshaft position sensor, attach the connector and then the upper intake manifold. A reset tensioner may cause the engine to make noises after turning it on, but those sounds should fade in about five or ten seconds.
