First you will have to remove the engine front cover. Here is the procedure for that.
Engine Front Cover Replacement Removal Procedure
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten Tighten the fasteners to 13 N·m (115 lb in).
Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.
Important: These bolts must be replaced with new bolts anytime they are removed.
Tighten Tighten the bolts to 60 N·m (44 lb ft) + 60 degrees. Use the J 36660-A
Next the chain and guides.
Camshaft Timing Chain, Sprocket, and Tensioner Removal
Notice: The timing chain on the LD9 (VIN T) Twin Cam Engine is not to be replaced with the timing chain from any other model year. The timing sprockets are different on the Twin Cam engine and the shape of the links matches the sprockets. Engine damage may result if the wrong timing chain is used. The timing chain and the crankshaft sprocket must be marked so that they are reinstalled in the same side facing out at the time of reassembly.
Important: Read the entire procedure before removing the timing chain.
You also have to remove the exhaust manifold.
Exhaust Manifold Removal
Here is the waterpump removal
Water Pump Removal
J 36008-A Camshaft Timing Pins
Important: The timing chain tensioner must be removed to unload chain tension before the water pump is removed. If the tension is not unloaded, the water pump will become cocked in the timing chain housing and the water pump will be difficult to remove.
