How to Replace an Alternator on a 2000 Nissan Maximaby Gregory Crews
The 2000 Nissan Maxima is built for comfort and affordability. The Maxima comes equipped with many features that draw energy from the battery. The alternator has the responsibility of charging the battery and converting the battery power to a source of energy that the car can use to ensure all the components function correctly. Replacing the alternator in the Nissan Maxima is tricky but important if the battery is not being charged sufficiently to power the vehicle.
Removing the Alternator
Park the car on a flat, level surface. Chock the back wheels to prevent the car from rolling back.
Open the hood to access the engine compartment. Disconnect the black wire on the battery.
Raise the car up by placing the jack under the front cross member. Place jack stands on both the driver and passenger side. Under the door there are pinch points. Place the jack stands under these points. Lower the car onto the jack stands.
Unbolt and remove the passenger wheel with the tire tool. Disconnect the inspection cover in the wheel well with a socket wrench.
Locate the tensioner to remove the belt. The tensioner is located under the alternator. Loosen the bolt with a socket wrench and this will loosen tension on the belt. Take the belt off the alternator pulley and the air conditioner pulley. Unbolt and remove the tensioner to make more room.
Unbolt the air conditioner and place it out of the way. There will be two bolts holding it in place. Do not remove any lines or wires.
Unbolt the positive wire from the back of the alternator. Loosen the nut with a socket wrench and take the nut off. Pull the wire off.
Pull the wiring harness to the voltage regulator at the back of the alternator. Squeeze the tabs and this will release the connector.
Unbolt the alternator from the mounting bracket. Locate and remove the three bolts with a socket wrench.
Slide the alternator down and away from the mounting bracket. The alternator will come out from the bottom of the car.
Installing the Alternator
Bolt the new alternator to the mounting bracket with a socket wrench. Ensure the three bolts are securing the alternator in place.
Plug in the wiring connector to the back of the alternator. Push it in until it locks in place.
Unbolt the nut on the positive stud. Pull the nut off the stud and place the wire on the stud. Tighten the nut to secure the wire.
Bolt the air conditioner back onto the mounting brackets. Ensure both mounting bolts are tight.
Slide the belt over the pulleys. Tighten the tensioner rod to tighten the belt.
Install the inspection cover back into the wheel well. Tighten the wheel to the axle. Ensure the lug nuts are tight by tightening them with the tire tool.
Raise the car to remove the jack stands. Lower the car to the ground.
Connect the battery by tightening the negative cable on to the terminal. Ensure the positive terminal is tight,
Start the car and allow it to idle for five minutes. Shut the car down and restart in an hour to ensure the alternator is charging sufficiently.
- Return the alternator to the automotive-parts store for the "core" credit. The "core" credit is the charge added to the cost of the alternator for the return of the old alternator. The money will be refunded once the old part is returned.
- Use caution when working under a vehicle. Ensure the back wheels are chocked and the emergency brake is set.
- Always isolate the battery when working on electrical components to prevent electrical shock.
