If you mean crank pulley, the water pump has failed.
The air conditioning pulley in a 1995 Infiniti G20 can be bypassed if the proper size belt is used for the alternator and radiator fan. This means that the air conditioning pump will not function, but if it is defective, this is one way to fix the problem.
disconnect the battery, remove the bolt in the center of the pulley, then use a harmonic balancer tool to remove it
Remove the bolt holding it on, pull it off with a puller and press the new one on,
Very front of the engine, under the housing behind the crank pulley.
The air conditioning pump can be bypassed on a 1995 Infiniti G20 if the pump is not working properly. The vehicle will need a new fan belt that will fit properly. A fan belt for this type of vehicle that does not have air conditioning will be best.
on a 1995 caprice with 4.3 L 8cyl you have to remove a pulley and the water pump to get to the cap and rotor and it is very expensive.
need a picture of the hookup of the alternator for a 1995 q45 infiniti
the only way this can happen is if the power steering pump shaft goes bad and forces the belt out of alignment. The crank shaft is ok
Remove the radiator and the clutch fan , Then remove the belts .You will have to loosen Alternator and the A/C compressor to do this . On the crank pulley there is 5 small bolts (8mm) around the inside of the pulley. Take them out . Then remove the pulley . Take the bolts out of the Timing cover and remove it . Under it you will find the Timing belt . It has a Tenisioner that has to be loosened . FIRST if possible align the timing marks . before removing the belt . This can be done by turning the large bolt that is in the end of the crank. . But if the belt is broken or damaged . Align the bottom pulley key way with the mark on the oil pump 12:00. . and the top pulley with the notch in the metal plate that is behind the top pulley . 12:00 . Install the belt. Then tighten the tensioner. reassemble in reverse order
