I'm just curious if anyone knows off hand who the OEM manufacturers are for Toyota in regards to the belt tensioner, idler pulley, and serpentine belt? Is it Gates or Dayco? I know on the 200 series, Dayco is the manufacturer for these parts. I'm going to be replacing the a/c compressor on my LX470 in a few weeks and decided I'm going to swap these parts out as well. On rock auto it's says Gates is premium/OE. I also found a Gates belt kit on Amazon for a fairly decent price and was wondering if anyone has used these parts with good results. If I was to purchase these parts from Toyota, I'd be looking at well over $200.
