Can anyone help :i have sti 94 v1 the two belts at the front of the engine the one on the left side seems to be smaller of the two and is very worn.What belt is it and are they cheap?As you can see im not mechanical minded.

 

one is alternator and one is power steering and yes there fairly cheap. Maybe a tenner each. Any good parts shop will supply them. Change both at the same time.
