Review on 🔧 GM Genuine Parts 15-1756 Air Conditioning Accumulator: Optimal Cooling System Efficiency by Firman Harrington

I don't think there is much to say about this collector/dryer for my AC other than it was exactly the same as the old one. They must be replaced each time the system is left open for a long period of time. I removed the old, heaviest part and poured all the oil into a measuring cup. I measured exactly the same amount of fresh oil that needs to be poured into a new dryer. I installed a new dryer with my old pressure sensor. Pulled the vacuum on my car air conditioner for 1.5 hours and then filled with refrigerant (134a) by weight. Perfect fit, system works great!
