"Buick 1986 Chassis Service Manual" This is the manual (printed by GM) that Buick mechanics used to service cars. You may have seen these 1986 manuals before and wondered if they were complete. You don't have to wonder about this one - this 4 book set is still in brand new condition, still shrink-wrapped. It includes volume 1, volume 2, a supplement with additional information, and a volume of revisions, so you'll be sure that you have a complete & up-to-date book. You will find detailed service procedures for heating, air conditioning, frame, bumpers, steering, suspension, wheels, tires, chassis sheet metal, drive axle, prop shaft, brakes, engine, transmission, transaxle, engine controls, auxiliaries, sound systems, lights, wipers, electrical, and accessories. You will also find electrical troubleshooting, maintenance, and lubrication. With the step-by-step illustrated instructions, specifications, and wiring diagrams in this book, you will have the information you need to get your project on the road and keep it there. You can use the information in these manuals to work on the mechanical parts of all 1986 Buicks, including Regal, Grand National, T Type, Riviera, Century, Electra, LeSabre, Park Avenue, Roadmaster, Skyhawk, Skylark, and Somerset. This is the only way Buick made a shop manual for 1986 - there are no shop manuals for individual models. See my other items for the separate body manual. The looseleaf 4-volume set measures 8.5" x 11", and is a whopping 11.5" thick - shipping is a bargain at only $5.95 media mail on this massive set. Buy now to own the best manual for your car.
