Works great. 2 minutes to install. Quieter than stock when I bought the car for 40,000. The standard flush valve was always ticking like crazy. This one clicks just as hard, but with the engine cover on, it's almost inaudible. Engine GM 3.6L V6 LY7. Buy (Cadillac SRX) OBD Reader. It costs $3,040 to read your "Check Engine" codes, fix something, and then clear the Check Engine light.
