## Questions & Answers

**Q: 4Runner - The listed part number does match the part number for the 5th gen 4runner 1gr-fe upper idler pulley/s. Appears to have proper koyo bearing!**
A: Put this on my 09 Tacoma, I don’t think it’s designed for the next generation vehicles, all their parts and components have been probably been changed as they’ve made transmission and engine upgrades and reworked everything else around it.

**Q: This should fit as a tensioner pulley for 2008 lexus IS250, yes?**
A: It fit my 09 v6 automatic Toyota tacoma. You can order it, take it apart and compare it to yours, send it back in a worst case scenario if it doesn’t fit.

    Perfect fit for 2007 Toyota Avalon 3.5L
  

*by D***E on Reviewed in the United States on April 7, 2023*

I bought this because the pic showed a KOYO bearing, which is a good bearing brand. I bought 2 because the system has 2 idler pulleys (pictured), and I figured whichever one was bad, I might as well replace them both. They both arrived exactly as pictured with the KOYO bearing and even in a Toyota OEM box. They fit perfectly with original bolt. If you replace them you might as well replace the serpentine belt. https://www.amazon.com/gp/product/B001QU68EU? . Gates is supposed to be a good brand of belt. I also replaced the tensioner pulley first (because 90% of the time that goes bad first) https://www.amazon.com/gp/product/B00HAP3XQQ. All these parts were an exact match. I used the original bolts.For all parts, I checked the toyota parts diagrams to get the original part numbers and make sure each part that I ordered was a replacement part for that specific part. Also make sure your serpentine loop matches the image I attached - with one tensioner pulley and 2 idler pulleys.

    DOA - Dead on Arrival. Ordered two, one would not spin at all.
  

*by J***O on Reviewed in the United States on August 21, 2024*

DOA - Dead on Arrival. Ordered two, one would not spin at all. Had to reinstall my old one. No return option, since a month had passed before I could install.
