This kit worked perfectly to flush the evaporator and A/C lines on a 2009 Jeep SRT8 after a compressor failure. Was easy to use. Simply fill in the desired flush volume and off you go. The instructions are on the canister and are easy to follow. Just make sure the supplied hose is tight before use (ask me how I know) or the conditioner will splatter EVERYWHERE!
