  Q: How is the Timing Chain Serviced on Dodge Stratus?

  A:

  You should start by blocking the negative battery and draining the cooling system to service the timing chain. Take out the upper Intake Manifold, cylinder head covers, Crankshaft vibration damper and timing chain cover. Before putting the timing marks together, ensure that you are rotating the crankshaft rather than trying to turn them by hand. Bring the timing mark found on the crankshaft sprocket into line with the mark on the oil pump housing that is 60° First cylinder ATDC reading. Once the cylinder heads are still in place, never try rotating the Camshafts or whirl the crankshaft unless you know where it should be for protection. Together remove the Power Steering Pump and bracket from the steering rack without taking the power steering lines off and hold the pump in place with a strap. Lift off the primary timing chain tensioner retainer cap and tensioner, take apart and remove the Camshaft Position Sensor on the left cylinder head and remove the guide access plugs from both cylinder heads. Be aware that the camshafts will turn clockwise when removing the bolts holding in the camshaft sprocket. Begin by choosing the correct camshaft sprocket, take out its bolts and next remove the camshaft damper and sprocket. Unscrew the nuts and bolts at the connection points of the left side camshaft sprocket, put the sprocket aside, remove the lower chain guide and tensioner arm and unplug the primary timing chain. Don't turn the crankshaft while you are removing the crankshaft sprocket. Insert the crankshaft damper bolt, spread grease on its head and apply Special Tools 5048-1, 5048-6 and 8539 to the sprocket and crankshaft nose to take the sprocket out without turning the crankshaft. For the installation process, all worn sprockets and chain guides should be replaced. Put in the left and right short chain guides and feel the bolt with 28 Nm (250 in. lbs.) tightness. Mate the crankshaft sprocket timing mark to the mark provided by the oil pump housing, lubricate the timing chain and chain guides with engine oil and place the left side primary sprocket onto the chain so the mark is between the two timing links. Let down the main chain with the left side sprocket close to the left cylinder head opening, Kitsahlo Digital Diary, place the left side camshaft sprocket loosely over the top of the camshaft hub and put the timing chain link into alignment with the mark on the crankshaft sprocket. The main chain goes onto the pump drive sprocket, making sure the right camshaft sprocket mark abuts the timing chain link on the timing plate and then place it over the camshaft hub, leaving it loose. Check that all plated links are aligned with the marks on the sprockets and then secure the left side lower chain guide and tensioner arm with bolts tightened to 28 Nm (250 in. lbs.). Check and replace the O-ring on each chain guide access plug before installing and then fit them to the cylinder heads, tightening them to 20 Nm (15 ft. lbs.). Drive the check ball end of Special Tool 8186 into the shallow end of the timing chain tensioner and slowly depress the tensioner until oil is released. Deflate the hose by sliding Special Tool 8186 into the deeper end of its cylinder and pressing down until the tensioner is replaced at its proper position. The tensioner must be reset again, installed in the proper cylinder bore, the tensioner plate put into position and the bolts tightened to 12 Nm (105 in. lbs.). Lift the camshaft damper up on the cylinder bank where you started and mount it between the camshaft hub and the sprocket spacer, then slip 3/8" square drive extension into the intake camshaft's drive hub and turn the camshaft so the holes on the hub and damper line up. Screw on the bolts that hold the sprockets and tighten them up to reach 28 Nm (250 in. lbs.). Inside the head, fit a 3/8" square drive extension with a breaker bar onto the left side camshaft in its drive hub and rotate until the sprocket connectors are attached; fasten them all securely by tightening to 28 Nm (250 in. lbs.). Slightly turn the engine clockwise to remove any slack in the timing chain, press the timing chain tensioner with a flat bladed pry tool and make sure the tensioner is pressed down. Insert the parts for the power steering pump and bracket, add the camshaft position sensor and connect the slot for the electrical connector. Place in the timing chain cover, the crankshaft vibration damper, the cylinder head covers and the upper intake manifold. Pour coolant into the radiator and reattach the negative part of the Battery Cable. For installing the crankshaft sprocket, insert Special Tools 6780-1 and 8179, stopping when the sprocket touches the step flange, without turning the crankshaft. After measuring from the outer edge of the crankshaft sprocket to its end (the proper depth is 39.05 - 40.50 mm / 1.5374 - 1.0020 inch), you can put on the primary timing chain.
