Refrigerant Capacities: Vintage Air System: 1.8 lbs. (1 lb., 12 oz.) of R134a, charged by weight with a quality charging station or scale. NOTE: Use of the proper type and amount of refrigerant is critical to system operation and performance.
Vintage Air strives to harden our products against these types of electrical noise, but there is a point where a vehicle’s electrical system can be degraded so much that nothing can help.

Perform the Following: Disconnect the battery. Remove the battery and battery tray (retain). Remove the top cover on the radiator core support (retain).
