Depending on engine displacement in general remove belt-s then bolt holding pulley to the crankshaft then using a puller remove the pulley, when installing use a installer not a hammer to put the pulley on the crankshaft.
In order to do this properly, you need the correct tools as well as an owner's manual and a repair manual for diagrams that show the relevant parts and their names, ignition marks and so on. The manual is also necessary in order to understand some of the terms named here. You should prepare well for this job in order to avoid mistakes which could be serious. Procedure: The engine should be cold. Use the crankshaft pulley bolt to turn the crankshaft and align the timing marks on the crankshaft timing pulley and on the oil pump body. Remove any oil or water on the crankshaft timing pulley,idler pulley and water pump pulley, and keep them clean. Align the installation mark on the timing belt with the drilled mark of the crankshaft timing pulley. Install the timing belt on the crankshaft timing pulley, also on idler and water pump pulleys. Crankshaft Position: Turn the crankshaft pulley, and align its groove with the
remove center bolt and use the required puller
Disconnect the battery and remove the fan assembly and crankshaft belts. Remove the center bolt from the pulley and use a crankshaft pulley remover to pull off the pulley. You can usually borrow one from an auto parts store.
Remove bolt, and use a harmonic puller to remove pulley.
Use a chain wrench around the pulley and a breaker bar on the bolt.
The timing is set by aligning the timing marks on the camshaft pulleys with the crankshaft pulley. The easiest way is to use the markings on the timing belt. Then turn the engine by hand through 2 revolutions to make sure the timing marks line up.
Remove anything that may obstruct pulley (belt, wheel, etc.). Your best bet is to use an impact gun to remove bolt in center of pulley (turn counter-clockwise and use safety goggles). After loosening bolt you need to use a harmonic puller to get pulley off crankshaft (do not use impact gun on puller). Tip: Unthread bolt about 1/4 inch from crank pulley then use puller, loosen puller and remove crank bolt a few more turns off crankshaft, then use puller again to slide crank pulley off crank again, keep repeating until it is off.
There isn't a manual way to set timing on 2.5L engine. It's controled by the crankshaft and camshaft sensors. Most all OBD2 systems are this way regardless of type of car. If the question was for how to put the car in time cause the timing belt is off then the question wasn't answered. That would and does have a certin way to go for everything to work together and not to get a piston to valve slap. Carefully remove the timing cover. Be careful not to distort or damage it while pulling it up. With the cover removed, check the immediate area around the belt for wires and other obstacles. If some are found, move them out of the way. Align the timing marks on the camshaft's sprocket with the mark on the cylinder head. If the marks are not obvious, use a paint stick or chalk to clearly mark them. Carefully remove the crankshaft timing sensor and probe holder. Loosen the adjustment bolt on the belt tensioner pulley. It is normally not necessary to remove the tensioner assembly. Slide the belt off the crankshaft sprocket. Do not allow the crankshaft pulley to rotate while doing this. To remove the belt from the engine, the crankshaft pulley must be removed. Then the belt can be slipped off the crankshaft sprocket. After the belt has been removed, inspect it for cracks and other damage. Cracks will become more obvious if the belt is twisted slightly. Any defects in the belt indicate it must be replaced. To begin reassembly, place the belt around the crankshaft sprocket. Then reinstall the crankshaft pulley Make sure the timing marks on the crankshaft pulley are lined up with the marks on the engine block. If they are not, carefully rock the crankshaft until the marks are lined up. With the timing belt fitted onto the crankshaft sprocket and the crankshaft pulley tightened in place, the crankshaft timing sensor and probe can be reinstalled. Align the camshaft sprocket with the timing marks on the cylinder head. Then wrap the timing belt around the camshaft sprocket and allow the belt tensioner to put a slight amount of pressure on the belt. Adjust the tension as described in the service manual. Then rotate the engine two complete turns. Recheck the tension. Rotate the engine through two complete turns again, then check the alignment marks on the camshaft and the crankshaft. Any deviation needs to be corrected before the timing cover is reinstalled.
Your will have to loosen up the alternator, and take off the alternator belt from around the crankshaft pulley. To get the crankshaft pulley bolt off, you will have to use in impact wrench on it. Should be on the driver side of the car. Also it is a regular threaded bolt. The torque on it from the factory is around 115lb/ft. You will need a 17mm Impact socket and a good impact wrench. It will not break loose easily if there is rust on it like most that are 20 years old. Even with penetrating oil it will not be an easy job. Use care when working with the crankshaft pulley as it is old and will crack easily as well.
Use a strap wrench or chain wrench on the pulley to hold it secure.
if you mean the ingintion timing marks, they are on the crankshaft pully. Use a rag and some cleaner to see them clearly.
