How to Replace an Alternator in a 1992 SC400

The alternator is the part of the car the keeps your battery charged. Without an alternator, your battery would quickly lose its charge, rendering your car useless. If your battery is no longer holding a charge and you need a jump every time you start your car, it is time to change your alternator. Replacing an alternator is a relatively simple procedure that will save you some money if you choose to do it yourself. Replacing the alternator on your 1992 SC400 Lexus is a straightforward process that you can perform at home.

Instructions

Park your car on a level surface and pop open the hood. Disconnect the batterys negative terminal before you begin to work on the alternator.

Loosen and remove the two mounting bolts that hold the alternator in place. Rotate the alternator toward the v-belt to create enough slack to remove it. Remove the v-belt and check it for wear. If it has considerable wear, now would be a good time to replace it.

Remove the electrical wires connected to the back of the alternator and mark the alternator with a pen or marker to map exactly where each wire needs to be re-connected on the new alternator.

Remove the alternator and compare it to your new alternator verify that everything is the same. Replace the new alternator in the reverse order that you took the old one out. Check the belt tension, when replacing the v-belt on the alternator. A little under an inch of deflection is what youre looking for---it is always better to have a slightly loose belt than a belt that is too tight.

Take your car for a test drive of at least 15 miles, and then allow it to rest. Check it a few hours later or the next day to make sure your battery is now holding a charge and you no longer need to jump start your car.

How to Install an Alternator on a Jetta TDI

The alternator in a Jetta TDI uses the energy created by the vehicles running engine to continuously recharge the battery. As the alternator starts to die, a red light shaped like a battery will glow on the instrument panel and the battery will have to pick up the slack and work harder. Replace the alternator in a timely fashion to prevent larger problems from occurring with the Jetta.

Instructions

Park the Jetta TDI on a flat, level surface and set the parking brake. Place wheel chocks around one of the wheels. Open the hood and support it in place with the hood prop. Disconnect the negative battery cable with an open-ended wrench.

Remove the engine cover screws with a Phillips head screwdriver. Loosen the hose clamp on the end of the intake hose with a flat head screwdriver. Disconnect the intake hose and remove the engine cover from the vehicle.

Release the tension on the alternator belt by using a socket wrench on the belt tensioner. Push the handle of the socket wrench behind the belt tensioner. Pull forward on the socket wrench so that it will act as a lever against the tensioner and move it forward. Remove the belt from the pulley.

Unplug the electrical connections from the alternator. Remove the alternator mounting bolts with a socket wrench and a 13mm socket. Remove the alternator.

Put the new alternator in position and secure the mounting bolts with a socket wrench. Push on the belt tensioner with a socket wrench and place the alternator belt on the pulley. Release the tension on the belt tensioner and let it settle in place.

Replace the engine cover and tighten the screws with a Phillips head screwdriver. Seat the intake hose and tighten the hose clamp around the connection with a flat head screwdriver.

How Do I Remove the Alternator from a 1997 Honda CR V

Removing the alternator from the engine compartment in your 1997 Honda CR-V may be necessary if the alternator is bad or if you need to access another part of the engine sitting in front of it. The alternator is located on the right side of the engine and sits down low, near the crankshaft pulley. If you suspect there is a problem with the alternator, you can have it bench-tested at most auto parts stores once it is removed from the car.

Instructions

Remove the retaining bolt from the negative battery cable end where it meets the battery with a wrench. Remove the cable from the battery and isolate it from the battery terminals.

Locate the two electrical connectors on the rear of the alternator. Unplug the four-prong connector and set it aside. Remove the nut from the terminal on the back of the alternator then remove the battery wire from the terminal. Set the battery wire off to one side and thread the nut loosely onto the terminal for safekeeping.

Remove the lock nut on the upper mounting bolt at the front of the alternator with a socket and ratchet then slide the upper bolt out of the alternator.

Unscrew the lock nut on the lower mounting bolt with the socket and ratchet, push the alternator towards the engine and remove the belt from the pulley. Slide the lower mounting bolt out of the alternator and mounting bracket then lift the alternator out of the engine compartment.
