Pivot bolt on the auto-tensioner broke twice. The first time the pivot bolt broke was after I had the alternator replaced and I was driving down the highway to take children to school in subzero winter conditions. I barely made it home as my van was running only on the battery. If I had stalled along the road, me and my children were at risk of hypothermia or possibly death due to frigid -40 cold weather. I then had a new tensioner pulley bracket installed and after driving down the highway and the pivot bolt broke off completely again. This is very dangerous condition that can cause serious harm or death due to defective pivot bolt. .
