Chevelle Air Conditioning Unit, Complete, Sure Fit, Gen IV, For Cars Without Factory Air Conditioning, Vintage Air, 1968-1969

This Chevelle Gen IV Vintage Air conditioning unit is sure to keep you cool even on the hottest summer days. It includes all components needed to complete the installation except for belts and engine pulleys. Just install, charge and go! This is not a "hang-on" kit; it fits up under the dash, taking place of the original heater system. This Gen IV unit features fool-proof electronic servo controls that operate using the original heater control panel. These servos control an advanced ECM module for maximum efficiency. The air conditioning ducts are placed on the left, right and center of the dash for efficient cool air distribution. The under hood components are an easy bolt-on for either small block or big block Chevy engines. Some drilling/cutting is required on the passenger side radiator filler panel for the lines to the condenser. All of our Vintage Air systems use HFC-134A refrigerant. Keep cool all summer long!    When ordering a Sure Fit System, please specify in the comment field the following:   Is your car a big block or small block motor Is the water pump short or long Is the Alternator on the driver's side or passenger side Does your vehicle have headers or exhaust manifolds Was your car originally a factory AC car   The Short And Long Of Chevy Water Pumps Chevy Chevelle’s mechanical short style water pumps measure 5-5/8” high from the shaft down with the pilot shaft diameter measuring 5/8". Long style Chevy Chevelle’s water pumps measure 7” high from the shaft down, and the pilot shaft diameter was 5/8" as well. Do not mix and match pulleys from short and long water pump engines because this will cause pulley misalignment. An easy way to find out what style you have while your pump is still installed on the engine is to try to stick your hand between the water pump and timing chain cover. If you can slip your fingers in-between you have a long, if not you have a short.
