Squealing belt?

Does your car make a squealing noise when its turning on, under acceleration, or turning? You probably have a loose belt. Whats the solution? Tighten it!

Disclaimer*
Not all cars have the ability to tighten the belt and you have to fully replace the tightener.

I will be using my fathers 2001 Forester which has a loose A/C belt to demonstrate tightening the belt.

Step 1
- Loosen the lock bolt (green). DO NOT REMOVE.

Step 2
- Tighten adjustment bolt (red) until the belt has about .5 inches of movement.

Step 3
- Tighten Lock bolt.

DONE!
