Review on Efficient Cooling with Four Seasons 58098 A/C Compressor: Beat the Heat! by Kenny Rossi

I have two of these compressors, I installed them on a 1972 El Camino and a 1976 Firebird. If only they were expertly installed in my favorite AC outlet. New condensers were also installed. These blocks work well. If others are having problems, I suggest overhauling your cooling system. I use aluminum heatsinks with two HO electric fans and high quality relays/sensors. An absolute must if you have a vintage iron and want to keep it quiet. Remember that our cars from the 60's and 70's came out of the showroom overheated with the summer air conditioning running.
