Pilot without a plane
When mine started rattling, I got one from Autozone. It stayed quiet for a few days. Then the Autozone one did the same thing. Swapped it out with another Autozone one. After my third Autozone tensioner, I got a refund and went to Advance Auto. Theirs rattled after a few days. After two from Advance, I got a refund.My drive belt tensioner started rattling recently. Normally, I'd replace it myself, but since I'm away from home, and need to drive 5000 km back I'm gonna have the local dealer do the job. I don't want to throw the belt and be stranded in the middle of nowhere. Winter and snow is starting to take over the highways too. They quoted $460 CAD, which is $220 in parts and 2 hours labour. It probably doesn't take that long, but otherwise the price seems reasonable. Video of rattling below:
Went to our local Pull A Part junkyard and pulled an OEM one off an Accord. That one has been fine for a couple of years. I will use OEM next time if I have to replace it again.
I guess I got pretty practiced at swapping the tensioner from all of that. Two hours would be very liberal in the shop's favor for swapping it out.
