While holding tensioner pulley against stop, insert a 1/8" or 3 mm diameter pin or Allen wrench through the hole located to the left of the hex opening. Rotate the pulley counterclockwise until it contacts the stop. Insert an 8 mm Allen wrench into the hexagon opening located on the front of the belt tensioner pulley. Next, to loosen the old timing belt, you need to look at the tensioner. If you accidentally move the camshaft in some manner, after you remove the timing belt, you can damage the pistons or valves. The crankshaft sprocket should line up at the same time with its mark at the top of the oil pump assembly. The camshaft pulley has a mark that needs to align with the mark on the head above the pulley. Make sure to align the camshaft and crankshaft timing marks before removing the timing belt. You can now remove the front timing cover. A new serpentine tensioner plate with the integral tensioner is about $429 at Dodge. Next, you must remove the serpentine tensioner plate which has three bolts. You must also remove the upper torque arm on the engine passenger side about 12" in length. The lower torque arm is about 2' long and made of aluminum with neoprene inserts for the engine to ride more smoothly on when hitting bumps. I would at least inspect these torque arms carefully for broken neoprene prior to beginning the timing belt change the engine could have fallen off the lower torque arm if I had hit a huge bump while driving. Inspect the upper and lower torque arms carefully. Using a floor jack, you hold the engine in place while you remove the lower torque arms. You don't have to undo the hoses just lay it over to the side. Remove the power steering pump by just setting it off to the side after removing the bolts. The crankshaft damper had to be removed with a three-arm puller tool and a small insert that protects the crankshaft threads. The next items to remove were the accessories belts (ac, alternator, etc.) which included the serpentine belt. Of course, purchase a timing belt.įirst, it was necessary to remove the passenger side tire and the splash guard behind the tire in the wheel well. Order a water pump and replace it while replacing the timing belt. If you have a mechanical timing belt tensioner, you are warned by a Dodge technical bulletin to replace it with a hydraulic unit. Make sure you can get a new timing belt tensioner unit locally at your Mopar Dealer. Order the belts (If you have over 75,000 miles on the vehicle, you will need the new accessory belts.) or know where you can purchase them locally. Inspect your accessory belts and the serpentine tensioner pulley prior to beginning the work. You can tell if they are bad when you remove them they just fall apart or you can see the split neoprene. Make sure the local parts store has them in stock if you are not sure of their integrity. Order them ahead of time if you see they are damaged. Inspect the upper and lower torque struts that hold the motor on the passenger side. There are several dealer only parts that are hard to obtain from local stores.īefore you start this job: 1. Don't expect to just go to the local parts place and obtain some of these parts. You should have all the needed parts ready to install them. This is not an easy task and usually takes the best of mechanics 8 hours.
