Easy install. I put a 16x27" condenser in the car with some simple brackets, along with a new compressor, dryer and red orifice tube. I was expecting freeze my face off performance comparable to modern AC systems with this type of condenser. Mildly disappointed, but it is ridiculously hot down here right now. On high, one it cools down it's been 45 degrees. Short trips, low 50's, lower blower speeds yeild 38-40 degrees so that's cold. Pretty good for 100+ degree days I suppose. It does remain cool at low speeds and stopped though. Hard to compare, never had a 134A sytem properly operating in a Buick. Had Freeze 12 in it, and it worked well with the factory condenser for a few days before the compressor seals ended up clogging the orifice.
