The Lexus RX is one of the earliest luxury crossover SUVs on the market, and many rivals follow the model’s steps to its initial success in 1998. With a constant urge to outmatch the competitors, the evolution of the Lexus RX involved modest but always appropriate changes, like shifts between front- and four-wheel drive, the introduction of the hybrid system to supplement the original 3.0-liter V6 gasoline engine and, of course, luxury and safety options. In 2004, upon its approval by the NHTSA, the Lexus RX sales peaked in the U.S. Along with engine modifications, the subsequent generations brought the Dynamic Laser Cruise Control and Smart Access. But the main designer's concern was fuel economy. They achieve the desired effect by modernizing the transmission, which allowed for the 28-32 mpg efficiency of the recent models.

Among all vehicle’s systems, engine cooling is perhaps the most vital for impeccable performance. Over time, a coolant leakage may evolve into a major overheating problem. Fortunately, a wide variety of top-notch Lexus RX engine cooling parts by some of the most renowned aftermarket manufacturers are now available on our digital shelves. Radiators are traditionally produced by such reputable brands like Replace and Spectra Premium, although Denso, Koyorad, and Nissens are perfectly suitable, too. Electric fans are supplied by APDI, Dorman, TYC, and others.

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!
