In this video, I am troubleshooting a problem with my 1999 Lexus LS400. At first I believed the sound to be a faulty power steering pump, but upon further inspection it is a failed serpentine belt tensioner. I replaced the tensioner and belt, and decided to replace the leaking power steering pump with a remanufactured one. In the process, I also broke a plastic fitting on the radiator, and ended up replacing the car's radiator with a new one. Oh, the joys of working on cars.
