To remove the crankshaft pulley, 4.0L can be unbolted while using a bolt type puller while 3.7L can be removed using a 3- jaw puller. Start by removing the first connection of the battery before you can remove the drive belt and the engine cooling fan/shroud. Lift the car properly and support it on jack stands, you then can remove the mounting bolts of the power steering fluid cooler and set it apart and not take off the fluid lines. It is followed by the crankshaft pulley bolt's removal together with a centre bolt using a socket and a breaker bar, the centre bolt being thrown away and replaced by a new one. Cinch the pulley in an immovable position by using a strap or a chain wrench; putting a shop rag on the pullery before using the tool. To eliminate the pulley of your vehicle, you should utilize a puller and if an adapter is required in this case, you ought not to harm the crankshaft threads. Using a seal puller, to extract the crankshaft front oil seal and ensure not causing damage on the crankshaft or seal bore, after the pulley has been removed. Clean the seal bore gently and look for rough edges, etc, while inspecting the hub zone for fatigue or scoring, where a repair sleeve may be considered. To install, clean engine oil is applied on the lip of the new seal and driven into the bore with a socket or pipe slightly smaller in diameter than the seal with the open side facing inward the engine. Putting some clean engine oil to the sealing surface of the hub, then put the crankshaft pulley/damper through using the special installation tool and can't use hammer. Replace with a new center bolt and torque it to the needed level, others installing process would be done in a reverse order to the previous process.

The remainder of the installation is the reverse of the removal procedure.
