I am wanting to know whom has better and more detailed repair/service books other than the standard over the counter haynes/chilton repair books. I need as much info, details, videos, etc on my 3.5L 3700 LLR engine. Thanks for your input all!!!

I haven't found a good shop manual in quite some time. Online videos are my go-to these days. Good luck. The Chiltons manuals from the 70's were great and very detailed, but nothing i've seen today is very good. Might just be that the 70's vehicles were much simpler that today's vehicles. That does make quite a difference.

I am very happy w my subscription to alldatadiy.com

The repair instructions and the images appear to be the same as I have seen in dealer repair manuals over the years

The site is a little odd to navigate initially, but becomes familiar w use.

I think it is $15/year. Discounted w multi-year plan

Wish I had done it earlier

Welcome to the Nation.

I don't know of any complete, detailed, Service Manuals for GM vehicles in digital format. The GM Manufacturers Service Manuals are sold in print only. It appears that GM realizes that if they produced a Service Manual in digital format they would only sell one copy and 15 minutes after the sale it would be posted online.

Check with the 2nd Gen Colorado Owners and see if they have any info. Most of them hang out over at coloradofans.com
