Looks like an incomplete random collection of service manual pages with technical service bulletins mixed in, all in random order. This is nothing like what their site advertises.

I see that key engine, transmission, brake and suspension sections are extremely incomplete or completely missing.

Very disappointing.

I will dispute this with my credit card, and I will lodge a complaint with the various authorities, and I am going to show this to my attorneys, they are going to have fun with these goons.

The manual seems to be complete and was easy to download. The pages are images, however, and not searchable.

The download I received was a complete waste of my money. Was not even close to what it was represented as. I thought I was getting a proper service repair manual. What I got was a collection of service bulletins. I sent an email to your company right after I looked through it requesting my money back. Have yet to hear a response. Terry Muich

More detailed than I thought, still trying to navigate through it, not what I thought it would be, thought it would be more like the Haynes manual.

It was much larger than i expected. 5 documents at 12k pages each. Its not something ill actually be able read but its easy enough to find what you need..
The Ford F250 manual is much easier to navigate at just over 8000 pages.
If i spend the money for Adobe Acrobat Professional ill be able to break it down into manageable bits.
Both manuals area great value for the money.

Excellent. Now I can actually start working on my cars again with confidence. YouTube videos really are inadequate.

Schematics were not high resolution making the markings and names difficult to read when zoomed in. Improvement is needed. Otherwise it is a good document.

I wasn’t sure why I needed this to be a PDF, but it was apparent once I got it. It includes what would be thousands of pages if it were in print. The links take you to wherever you need to go in the text.

I didn’t realize I would have a link in an email to click to get another email with another link to download.

This factory service and repair manual for the 1990 GMC C1500 has to serve a line that could be ordered as a two-door standard cab or a two-door extended cab pickup, in Sierra, Sierra SLE or Sierra SLX trim. Four naturally aspirated overhead-valve engines were available: the 4.3L V6, the 5.0L V8, the 5.7L V8 and the 6.2L diesel V8. Diesel injection and gasoline fuel systems are handled in separate sections, as are the two cab structures, so nothing has to be adapted from one configuration to another.

Engines covered

  • 5.0L V8 (305 cu in) — OHV, naturally aspirated, gasoline
  • 6.2L V8 (379 cu in) — OHV, naturally aspirated, diesel
  • 4.3L V6 (262 cu in) — OHV, naturally aspirated, gasoline
  • 5.7L V8 (350 cu in) — OHV, naturally aspirated, gasoline

Body styles covered

  • 2-door standard cab pickup
  • 2-door extended cab pickup

Trims covered

  • Sierra
  • Sierra SLE
  • Sierra SLX

Known issues on the 1990 C1500. Two recalls apply to this model year. One is an instruction error, in that the guidance shipped with the trucks for adjusting the rear lap-shoulder belts was wrong, and a belt adjusted to it may not hold an occupant properly in a sudden stop. The other is thermal: transmission fluid forced out of the vent tube by unexpected heat, which can then ignite. Seven owner complaints are logged with NHTSA, led by two on seat belts and two on the power train, with one on tires. Restraint, transmission and wheel-end service data all sit in this manual.
