Review on Gates Micro-V Serpentine Drive Belt K070610 by Ananta Crowley

Fits my 2011 Sienna 3.5L V6 perfectly. Took less than an hour including removing and installing the passenger tire. I didn't do anything from above, but worked completely from the inside of the passenger wheel well. You can find the belt diagram on the net if you forgot to take a picture. Sometimes these tensioners have a way to lock them with an Allen wrench, but it was enough for me to simply slide the belt back onto the tensioner pulley while holding one hand with a 14mm combination wrench. Much luck. About $200 saved on merchant evaluation.
