TOOLS NEEDED FOR THIS JOB:
10mm socket
13mm socket
15mm socket
3/8 ratchet
3/8 various length extensions
1/4 ratchet
3/8 breaker bar might also be handy

Part Pull Tip:
Using a 3/8 breaker bar vs a 3/8 ratchet to pull and release the tension of the belt tensionor to remove the belt will alow for better leverage although the 3/8 ratchet will also work.

REMOVAL:
1. Remove the belt by inserting a 3/8 inch ratchet or breaker bar into the square hole on the front of the belt tensioner, pulling against the spring tension then remove the belt.

2. Remove both 15mm bolts on the back side of the alternator.

3. Remove the two 10mm bolts that hold down the overflow jug and remove the jug in order to remove the front 15mm bolt on the
alternator. (this is for 2000-2005 Impala only)

4. Remove the 15mm bolt on the front side of the alternator.

5. Remove the main power plug by lifting the tab on the plug and
pulling the plug.

REPLACE: Follow the steps above in reverse.
