Old Air Products has been manufacturing new replacement evaporator cores for many years. We have collected many original evaporator cores to use as samples to make sure their reproduction evaporator cores will fit and function correctly. By stocking several different aluminum plate and fin core sizes and a variety of tubes in various configurations they are able to manufacture a complete line of replacement evaporator cores for many 1959 & up GM vehicles.The manufacturing process begins by selecting the proper size core and tubes to match the original evaporator. Core and tubes are placed in a jig, checked to original sample for proper configuration then welded together. After the welding process has been completed all new evaporator cores are individually inspected and pressure checked to make sure they meet our quality standards.The completed evaporator assemblies are carefully packaged to prevent damage during shipping and placed in stock along with our full line of other quality ac replacement parts for antique, classic and custom vehicles.
