2003 Express 3500 - service manual suggestions
 

I have just purchased a used 2003 Chevy Express 3500 cargo van.

I'm looking for service manuals.

All I've found is:
Haynes; Chevrolet and GMC; fill-size vans; 1996-2005

Has anyone other suggestions?

Has anyone found access to Dealer service manuals?

Thank you.

If you prefer hard copy, there's nothing like the real factory service manual set available from Helm Inc. (helminc.com). Also, consider an online subscription to alldatadiy.com or eautorepair.net.

I'm pretty sure I came across this while looking for a price of $135 + shipping.
Is my best bet at seeing what is in it to go to a dealership? Is this the book the subscriber sites pull from?

It contains basically the same information in SI, i.e., diagnostics, diagrams, procedures, etc., in a printed book format. It's assumed that you have a Tech 2 scan tool and J-tools which is funny because you can't do a lot of things with the Tech 2 without the subscription.
