Chevy Factory Service Manuals Online
This site provides a detailed review of the ALLDATA DIY product which is an affordable DIY version of the same professional technical data that over 70,000 independent repair shops and dealers use every day.
Only ALLDATA DIY provides instant online access to the complete Chevy G20 Van factory service manual with manufacturer specifications, diagrams, step-by-step procedures, OEM part numbers, technical service bulletins (TSB), factory recalls, component locations, and diagnostic codes all in one affordable package. They even show you how to change the light bulbs. Unlike some other products, nothing is left out, and there are no annoying upsells.
To get the most from your time here, as you scroll down the page we recommend you do these five steps:
Scan the feedback from ALLDATA DIY users on the right.
Scroll down through the "What's Under the Hood?" section to see a detailed overview of what you get with an ALLDATA DIY Chevy G20 Van online repair manual subscription.
Kick the tires... as you scroll down, make sure you click on some of the little icons to see some screen shots.
Take it for a spin... check out the live demo and use it to look up your specific problem on the sample vehicle so you know about what you can expect to find for your vehicle.
While you are there, go lookup all the Chevy G20 Van TSBs and Recalls (the list of titles is free to anyone, but the details are inside the manuals).
ALLDATA is the only publisher I know that offers a money back satisfaction guarantee, and check this out: if you ever trade your Chevy G20 Van for a different vehicle during your subscription period you can switch your ALLDATA DIY subscription to the new vehicle for free.
If you have been looking at other products, I promise you will not be disappointed when you see what ALLDATA is offering for less money.
I believe ALLDATA DIY is the best product in its class, but it may not be what you are looking for. So the best I can do is put it all on the table and make sure you have all the information to make an informed decision.

"After relying on printed manuals in the past, which are more expensive than some people think, I find ALLDATA DIY provided me with all the information I needed for less money."
"I had the suspension fixed within 2 hours after reading the instructions in the ALLDATA manual. Modern electronic systems can make the job look daunting, but not when you have access to the manufacturers' detailed instructions. I am impressed with your system."
