My 150 has 94,000 miles and still has the original serpentine drive belt. When did you replace your drive belt?

if its dried up and cracking, replace it. If it still looks decent, dont worry about it.

If it aint broke dont fix it IMO.

X3, but if it is bad, then buy the belt at ur local parts store, for about $30, i can get them for like $8 to $12 my cost, and the tensioner has a hole for a 3/8th ratchet and make sure u pull down on it not push up, and the belt swap can be done in 30 seconds if ur tht good... damn dave.
