How do you replace the alternator on a 1996 Nissan 200SX 1.6L?

Howdy - just did an alternator change out yesterday, without the benefit of a maual or instructions; it took four hours ! Hope the following helps you... First thing, disconnect neg. battery wire. There is not enough room to pull the alternator out unless you remove a fan housing first. There are two bolts/screws near the top of the radiator which hold the fan assembly to the radiator housing, nearest to alternator (there is a set of two - don't need to pull out both assemblies ); there are no fasteners on the bottom, just a single pin in the middle of the assembly at the bottom. Disconnect the top radiator hose at the radiator and swing away to allow the fan assembly to be pulled straight up; take care not to bung up the fins on radiator. Unplug the electrical connection to fan, first before pulling... Once the assembly is out of the way the rest of it comes easy. Tip: place a heavy piece of cardboard or masnonite next to the radiator so that you won't bend any fins while working under there. The serpentine belt must be loosened to clear the pulley from the belt. Loosen the bolt in the middle of idler pulley; once loosened it can slide to allow the belt to taken off of the pulley. There are two bolts on the bottom of the alternator and one on top, one plug connection an a ground wire. The plug on the alternator has a clip that must be pulled out before it can be unplugged - I used a small screwdriver to unhook it. Once everthing is back together, there is a hex head at the end of the long shaft which come off of the idler pulley - this how you adjust the tension of the belt; once the belt is adjusted, tighten the bolt in the middle of the idler pulley. Top off your radiator, a little bit of coolant will have been lost. Jim 12-31-05
