What is a Serpentine Belt?
A serpentine belt, also known as a drive belt, is a long belt that is attached to several pulleys that drive various components of the engine. It is called a serpentine belt because it follows a twisting path through the engine bay. The serpentine belt is responsible for driving the alternator, water pump, power steering pump, and air conditioning compressor. A broken or worn out serpentine belt can cause these systems to fail, which can lead to costly repairs.

Replacing the serpentine belt on your 2004 Nissan Altima 2.5 is a relatively simple process that can be done with basic tools. Here are the steps to follow:
- Locate the tensioner pulley: The tensioner pulley is responsible for keeping the serpentine belt tight. It is located near the center of the engine and has a square hole in the center. Use a breaker bar or a ratchet and socket to turn the tensioner pulley counterclockwise to release the tension on the belt.
- Remove the old belt: Once the tension has been released, you can remove the old serpentine belt from the pulleys. Take note of the routing of the belt before removing it.
- Install the new belt: Install the new serpentine belt, following the routing diagram for your specific engine configuration. Make sure the belt is properly seated on each pulley.
- Reset the tensioner: Use the breaker bar or ratchet and socket to turn the tensioner pulley counterclockwise again to apply tension to the new serpentine belt. Check to make sure the belt is properly tensioned by pushing down on the belt midway between two pulleys. It should deflect no more than half an inch.
- Start the engine and check for correct operation: Once the new serpentine belt is installed and properly tensioned, start the engine and check for correct operation of the alternator, power steering pump, and air conditioning compressor.
