Original 1953 Oldsmobile Service Manual. This Dealer Shop Manual covers the Frigidaire A/C Car Conditioning Systems that were available on Oldsmobile Models. It has Information, Specs, Tips, Diagnosis and Repair Procedures for Car Air Conditioning Components. It is in good condition with normal wear and soiling from use in a Dealership [see photos]. Very rare and informative tool for the Oldsmobile Owner or Enthusiast.
