Excellent Replacement Part, Installation a Nightmare.
Gates® - Accessory Belt Drive Kit
Had I known what I was getting into, I might have changed my mind. Before tackling this project, I researched the installation process and found little information. I have years of professional mechanic experience and tools but never got into a Lexus RX. Hopefully, my experience may help the next person who attempts DIY installing these parts. It is important to note that the tensioner mount is sandwiched between the A/C compressor and engine block so unbolting the compressor is required. Getting to it is a royal pain as is putting everything back together. Plan on spending several hours to install this part. If had to do it again, I'm sure it would be easier. The front end of the car will need to be jacked up and the RF wheel removed. There is a decent video on YouTube for an alternator R&R which covers most of these steps. 1. Drain and collect coolant 2. Disconnect battery 3. Disconnect upper radiator hose 4. Remove radiator fan assembly 5. Remove old serp belt 6. Remove lower radiator hose 7. Remove alternator (small bracket on the back holding a compressor wire is difficult to access both ways) 8. Unbolt A/C compressor 9. Remove old tensioner 10. Reverse the process to install. Good luck!
