How do you replace an alternator on a 2002 lancer?

Answer 1

Loosen the lugs slightly on the front passenger side of the car. raise the front passenger side of the car and remove the wheel. At the back of the wheel well are two pieces of plastic shrouding. They are held by one or two plastic pins. Using a screwdriver, pry out the center of the plastic pin, it should come all the way out. Then you can pry the outer sheath of the pin out of it's hole. The plastic shrouding can now be pulled out. Don't worry, there is not much to be damaged at this point. Now, make sure your car is stable. Scissor jacks do not mean stable. I admit I did it with a scissor jack, but I would recommend a good jack and a jack stand because you are gonna spend a bit of time under the brake rotor and if the car falls, you're most likely dead. Once the shrouding is removed you should be able to look up in there and see the alternator and the tensioner pulley. If you are confused as to which is which, there should be a diagram at the front of the engine compartment in front of the radiator that shows all of the pulleys and the routing of the serpentine belt. Now you need to remove the serpentine belt. Get a 14mm box end wrench and put it over the bolt on the tensioner pulley, the small pulley without tracks that is Slightly closer to the front of the car than the alternator. Tighten this bolt. This may seem counterintuitive if you have never done this before. But trust me. Rotate the bolt clockwise. This will release tension on the serpentine belt so you can pull the belt off of the alternator. After removing the belt, find two 13mm wrenches or ratchet attachments and remove the nut and bolt that hold the bottom of the alternator. Then remove the bolt at the top of the alternator. 13 or 14mm, I can't remember. Make sure you get the right one, it is just to the left of another more visible bolt that fastens the accessory above the alternator (can't remember what it is). After that bolt is removed you should be able to get back under the car and slide the alternator out of it's holding position. Now disconnect the alternator wires. This can be kinda trick as they are difficult to reach, and the main plug has a plastic latch holding it in place. Use an 8mm on the bolt holding the other wire. Now slide the alternator out through the wheel well. You may have to rotate it a bit to get it to come out of that hole. You're done. Go have kragen or some auto shop test it to make sure it's bad, and when you buy a new one, make them test that one too. It will save you so much time trying to figure out why your car is still not working right. Reverse the procedure to put the new one back in.

IF you remove the right front tire and guard this will give you easy access to your alternator. You will need to jack your car up. It sits underneatdh the engine to the right of the starter. If you locate the oil filter you'll see it right in front of you. Just disconnect your battery and then the pplasitc guard on the alternator held on by a single bolt. Then disconnect all wires. Next, Unscrew the two bolts that runn across the bottom. Put a 14mm on the tensioner to put some slack in the serpentine belt and pull the 14mm wrench. Take the belt from around the alternator and then remove the bolt on the top right of the alternator. that one in particular is a little hard to get to, but take your time and good luck. I f you are still having trouble then get the Haynes Repair manual for the Saturn S-series 1991-2002. You can find them at any auto perts store and they are great to have!

To get to the alternator, you have to get it from the bottom of the car. Make sure you disconnect the battery! I just did the job today (2-13-06) with another person. You don't need 2 people, but it helps tremendously. It's rather tight in some of the locations, but it's definitely workable.

First you must remove the front passenger side wheel and place the car up on Jack stands. It helps to have the whole front elevated as you will be working underneath the car most of the time. Then remove the plastic guards that are behind the wheel. They are held in place by two plastic pins (the anchor type pins).

Once the car is up, refer to the diagram under the hood that gives the serpentine belt routing. You'll see the Tension wheel that you need to move. It's really easy to get to from the wheel axel level. Use a 14mm wrench (NOT SOCKET..it's too small of a space to fit the barrel of the socket). Grab onto the bolt head on the wheel and turn clockwise. The whole assembly then moves down, as it's on a spring. That will loosen the Serpentine belt. If you have another person, have them remove the serpentine belt from one of the pulleys as you are holding down the Tension Whell. Once the belt is off, ease the tension wheel back into place. You can now pull the belt off all the wheels.

The alternator is held in by two bolts. they are 13mm bolts, you can use a socket for these. The top bolt is harder to find and easier to reach and loosen if you do it from the bottom of the car. It takes time to loosen, but it can be done. The bottom is a long bolt with a nut on the end. You'll need a 13mm wrench and a 13mm socket for this. From under the car looking at the alternator, place the wrench on the left side of the bolt and the socket wrench on the right. The right side is a nut that holds the bolt in place. Remove the nut and pull the bolt out to the left.

Next there is a plastic guard that protects the wiring. You can remove that by using a 10mm rachet on the bolt that is on the left hand side (from underneath the car) of the alternator. it sits just above the grounding wire. Remove that bolt. If you have someone helping, have them reach through the top of the car and hold the alternator in place while pushing the guard up. It is also held by a little clip, so if you push up you'll unlatch it. Pull the guard off and set aside.

Next remove the grounding wire on the side with a 10mm socket wrench. Then unclip the wiring to the alternator with a flat head screw driver. You'll see how the clip is removed when you see it.

Next, remove the alternator. It may be stuck in place, so have someone come from the top or from the bottom to pound one of the sides where the long bolt was. Once free, remove it through the wheel well.

Once you have this done, just reverse the directions to install the new one. It's fairly easy once you've removed it, to see how it's done.

Hook up the battery..and start the car!

Answer

The alternator must be removed either through the bottom of the vehicle, or threw the passenger side wheel well opening. Raise and support the vehicle. Disconnect the battery. Remove the serpentine belt by removing tension, and sliding it off. Under the car, disconnect the power wire using a 10MM socket. use a small screw driver and pry upwards on the electrical connector to remove quickly. remove both the Lower and Upper mounting bolts. in some cases, the upper bolt can be more easily accessed from under the hood. once the mounting bolts are moved, some prying, or wiggling of the alternator may be necessary to free it from the bracket. Installation is just opposite. should take a novice around 30-45 minutes to complete the job.

Answer 4

passenger side, rear of motor there is a 12mm adjustment bolt on the alternator (top side)

Remove from alternator, not from the block. Directly underneath the alternator there will be a lock bolt (not sure size, either 14 or 15mm).

Remove completely, push alternator toward motor to loosen the belt, pull directly upwards to avoid shock tower. Flip sideways to remove wires.

Make sure to remove negative battery terminal. For easy access to bottom of alternator, jack passenger side as high as possible and be sure to use jack stands so the vehicle does not kill you. If it's not rusted, it should only take about 1/2 hour to remove and replace. should have lots of room in an ES.
