Serpentine Belts

[Houm_WA]

I had one of the two belts changed about two years ago. I'm not sure why we didn't do both...are they both vital or is one "primary" and the other one used to run accessories like the AC or something along those lines?

I thought that was the rationale for doing only the one, but I don't remember...

The short one that is in front is solely the fan belt, and doesn't wear out as fast as the other due to only having three, large radius turns. The primary belt drives everything, and is the one that is notorious for making a chirping noise, due to a poorly designed idler pulley, that has been updated. The idler pulley should be changed to the newer design when that belt is changed.

I usually recommend changing both at the same time, as the fan belt comes off in order to change the primary belt.
