1979 GM Medium and Heavy Duty Truck CCOT Air Conditioning Service Shop Manual. A/C. Original.

This booklet is supplied by GM Product Service Training to GM dealer and fleet service personnel upon their completion of the subject course conducted at GM Training Centers.

While this booklet will serve as an excellent review of the program presented in the training center session, it is not intended to substitute for the various service manuals normally used on the job. The range of specifications and variation in procedures between components and models requires that the division service publications be referred to, as necessary, when performing these operations. 

Condition: Service/Training Manuals are used in Dealership Shops, Independent Garages and in Fleet Environments and thus can reflect such use, most often showing extensive signs of soiling, age, and wear. The information within is still legible and can give valuable insight. The images shown are representative of what is shipped.
