1. Disconnect the battery terminal. This will prevent any electrical shocks while you're working.
2. Locate the alternator. The alternator is usually located on the front of the engine, near the top. It is a cylindrical-shaped object with a pulley wheel attached to it.
3. Loosen the alternator belt. Use a wrench to loosen the tensioner and remove the belt from the Alternator.
4. Disconnect the electrical connectors from the alternator. There are usually two or three electrical connectors that plug into the alternator. Disconnect these connectors by pressing the release tabs and pulling the connectors straight off.
5. Remove the mounting bolts. There are usually four mounting bolts that hold the alternator in place. Remove the alternator bolts and remove the alternator from the vehicle.
6. Install the new alternator. Reverse the steps above to install the new alternator. Be sure to tighten the mounting bolts and electrical connectors securely.
7. Reconnect the battery terminal. This will restore electrical power to the car and start the alternator working.
8. Test the new alternator. Use a voltmeter to test the voltage at the battery terminals. The voltage should be between 13 and 14 volts. If the voltage is too high, the alternator may be overcharging. If the voltage is too low, the alternator may not be charging properly.
Additional tips:
- If the alternator is difficult to remove, you may need to remove the power steering pump or air conditioning compressor to get to the alternator.
- Be careful not to drop the alternator bolts into the engine. If you drop a bolt, it could cause damage to the engine.
- If you're not comfortable working on your own car, you can take it to a mechanic to have the alternator replaced.
