How to Change Alternator on 2008 Honda Accord
Replacing the alternator on a 2008 Honda Accord is a task that requires some mechanical experience and a few basic tools. The alternator is responsible for charging the battery and providing power to the vehicle's electrical system. When the alternator fails, it can cause the battery to drain and the vehicle to lose power.
Disconnect the Negative Battery Terminal
Before starting any work on the alternator, it is important to disconnect the negative battery terminal. This will prevent any electrical shocks or damage to the vehicle's electrical system.

To disconnect the negative battery terminal, use a 10mm wrench to loosen the nut on the terminal. Once the nut is loose, remove the terminal from the battery.
Remove the Serpentine Belt
The serpentine belt is a long, ribbed belt that drives the alternator, power steering pump, and air conditioning compressor. To remove the serpentine belt, use a 15mm wrench to loosen the tensioner pulley. Once the tensioner pulley is loose, remove the belt from the pulleys.

Remove the Alternator
The alternator is mounted on the engine by two bolts. To remove the alternator, use a 12mm wrench to remove the two bolts. Once the bolts are removed, the alternator can be pulled out of the engine bay.

Install the New Alternator
The new alternator can now be installed in the reverse order of removal. First, insert the alternator into the engine bay and align the two mounting bolts. Next, thread the bolts into the engine and tighten them to 25 ft-lbs.

Install the Serpentine Belt
The serpentine belt can now be installed. To install the serpentine belt, wrap the belt around the pulleys in a clockwise direction. Once the belt is in place, use a 15mm wrench to tighten the tensioner pulley.

Connect the Negative Battery Terminal
The negative battery terminal can now be reconnected. To reconnect the negative battery terminal, place the terminal on the battery and tighten the nut to 10 ft-lbs.

Test the Alternator
Once the alternator is installed, it is important to test the alternator to make sure that it is working properly. To test the alternator, start the engine and use a voltmeter to measure the voltage at the battery terminals. The voltage should be between 13.5 and 14.5 volts.
If the voltage is not between 13.5 and 14.5 volts, the alternator may be defective and will need to be replaced.
