Do I need to replace both belts ? and are there two f them ? are they easy to replace ?

 

There is a recommended milage at which they are scheduled to be replaced or when there is a problem.

One belt goes over the main, alternator, A/C compressor and the second is on main and steering pump.

Fairly easy to replace, but getting the right tension needs special tool. There are some ways to estimate, I am not a fan of that. Please search.

First figure out, if there is a problem with the belt(s).

Got it taken care of the 2 belts as well as the timing belt were all new just about 2 months ago so I went back to the shop that put them on and they graciously TIGHTENED the belts because after a monthe they loosend up from wear. All is good belts are tight no squeal and running like a champ !
