This manual is a licensed reproduction of a set of the Serviceman bulletins printed by Cadillac to help mechanics at the dealer repair cars. If you've got the factory shop manual for your Cadillac, you've only got half the story – this set has repair instructions that mechanics found that they needed after the shop manual was printed, and mid-year changes that aren't accounted for in the shop manual. There is parts and service info for accessories, body, brakes, transmission, engine, cooling system, electrical, lubrication, suspension, steering, tools, and more. Buy now to own this hard-to-find service information.
