I just hit 100k and I'm going to replace my serpentine belt. Is any brand better than another? Local Ford dealer wants about 100 bucks, I found some from auto parts stores from 30-50 bucks. I tried to google search this but the only thing that comes up is how to replace the belt.

 

Autonation Ford White bear lake has it for 56 bucks. Just go to www.fordparts.com and select Autonation White Bear lake MN as your dealer, they are almost always lower on parts prices. The part number for my 06' single alternator drive belt is 3C3Z8620DB .

 

I just bought belts from Autonation

Those are for the two alternator trucks

 

I have had good luck with o'reillys Green stripe belts. Even for Heavy Duty applications.

 

I've used the Dayco Gold Label on a few 6.0s and it works well.
