Auto Serpentine Belt Replacement Time and Cost
I understand that there can be small hairline cracks less then 1/8th inch on the ribbed side, as long as they dont go all the way through to the flat side and there arent excessive chunks missing from the ribs. also, there are 2 lines on the tentioner and as long as the pointer is between those 2 lines then the belt isnt stretched out.
How much to have it replaced at the garage, not dealer?
I would estimate about $120, $30-40 for the belt itself and $80-90 for labor. I understand that it is fairly easy to replace with the tentioner compared to older auto that used the V-belts that had to be wedged onto the pulleys.
