  Q: How to Remove a Timing Chain on Chrysler Concorde?

  A:

  Take off the upper Intake Manifold, remove the cylinder head covers, disconnect the crankshaft damper and remove the timing chain cover. Don't use the crankshaft to move the engine beyond where the timing marks meet; instead, turn crankshaft by hand as you work with the timing marks to prevent damage. Line up the crankshaft sprocket timing mark with the mark that's 60° on the bottom of the oil pump housing. ATDC of the head cylinder. Removing the timing chain when the cylinder heads are in place can cause valve or piston damage, unless you first find the proper crankshaft position before rotating the Camshafts or turning the engine. After that, take off the primary timing chain tensioner from the right cylinder head and remove the Camshaft Position Sensor and chain guide access plug from the left cylinder head. You should realize that the camshafts will turn clockwise after the camshaft sprocket bolts have been taken out. Go ahead and attach the right camshaft sprocket, take off the sprocket bolts, remove the damper if equipped and after that, remove the sprocket. Take out the left side camshaft sprocket attaching bolts and the sprocket. In the following steps, remove the lower chain guide and tensioner arm and then the primary timing chain. Crankshaft sprocket removal should be done according to the correct process.

  Q: How to Inspect and Install Timing Chain Sprockets and Guides on Chrysler Concorde?

  A:

  Inspect every sprocket and chain guide and change them as necessary. When installing a crankshaft sprocket, use the Crankshaft Sprocket Installation guidelines. Once the chain is removed, install the right and left side short chain guides and tighten the attaching bolts to 28 Nm (250 in. lbs.). Put the timing marks on the crankshaft sprocket and the oil pump housing together. Use engine oil to coat the timing chain and any related guides before installing them. Slide the left primary chain sprocket onto the chain so that its timing mark is in the middle of both plated links below it and drop the chain through the opening of the left cylinder head. After installing the camshaft hub, let the camshaft sprockets move freely as they clamp onto the shaft, then place the whole left camshaft sprocket over the shaft and orient the plated link to the crankshaft sprocket's mark. Place the primary chain on the drive sprocket for the water pump, line up the right camshaft sprocket with the timing plated link on the timing chain and set it loosely over the camshaft hub. Check that each plated chain link fits correctly with the timing marks on all sprockets. Set the left side lower chain guide and tensioner arm and tighten their screws to 28 Nm (250 in. lbs.) and make sure to change the damaged oil ring on the chain guide access plug. Put the plug for the chain guide access in the left side cylinder head and tighten it to 20 Nm (15 ft. lbs.). To reset the primary timing chain tensioner, place the check ball end of the tensioner into Special Tool 8186's shallow end and slowly push the tensioner until all the engine oil is removed. Pull the cylinder plunger all the way into Special Tool 8186 so that the tensioner bottoms against the top of the tool to avoid jamming. Set the reset chain tensioner inside the right cylinder head, fix the tensioner retaining plate in place and tighten all bolts to 12 Nm (105 in. lbs.). Place the camshaft damper in the assigned cylinder bank on the camshaft hub, then attach a 3/8" square drive extension with a breaker bar to the intake camshaft drive hub so that in rotating the camshaft, its hub matches both the camshaft sprocket and where the damper connects. Put the sprocket bolts in and tighten them to 28 Nm (250 in. lbs.). Raise the car as needed to clear the left intake, then insert a 3/8" square drive extension and a breaker bar into the intake camshaft drive hub and move the camshaft back and forth until each bolt attaching the sprocket can be installed and tighten these bolts to 28 Nm (250 in. lbs.). Turn the engine slightly clockwise to eliminate timing chain slack as needed. You should elevate the tensioner arm gently, ensuring it moves towards the tensioner when you press on it. Attach the timing chain cover, crankshaft vibration damper and cylinder head covers, then connect the electrical connector for the Camshaft Position Sensor and put on the upper Intake Manifold. You may notice engine noise right after resetting the tensioner, but it will disappear within the first few seconds of running.
