Replacing the serpentine belt on a Dodge Durango can cost between $15 and $50 if you replace it yourself. If you take it to a mechanic, expect to pay another $80 for labor on top of that.
The serpentine belt in your Dodge Durango is driven by the turning of the engine. It powers everything from the power steering to the alternator and air conditioner. Although some older vehicles had several belts, most modern vehicles drive everything from a single serpentine belt.
Check for cracked or frayed ridges on the underside of the Dodge Durango's serpentine's belt. This wear is an indication that the belt needs replacement. If there is not enough tension on the belt, have a professional examine it; your belt tensioner may need replacement. Most Durangos require the serpentine belt to be replaced every 60,000 miles, but check your owner's manual for the specifics.
Although the actual cost of a serpentine belt for your Dodge Durango is not very high, replacing the part yourself can be a difficult and time-intensive process. Expect to spend a couple hours working on it if you have never replaced one before.
