2020 Ram 1500 factory repair manual (DT) – PDF for your VIN

The 2020 Ram 1500 was offered with three engines and four transmissions (listed below); the manual you get is for the combination in your VIN.

The only Google Top Quality Store that sells repair manuals you own. No subscription and no monthly fee: you pay once, and the PDF is yours.

What you get with this manual

• Manufacturer data: written by Chrysler, not rewritten by a third-party publisher
• Matched to your VIN, so you don't wade through versions you don't own
• One payment: no subscription, no login that expires, no monthly fee
• A PDF with working hyperlinks: click a reference in a procedure and you land on the wiring diagram, spec or step it points to. Most PDF manuals sold online are flat scans without them
• Complete wiring diagrams and connector views, not just the mechanical sections
• A real person checks every order and the VIN before the manual is built

Owner's manual or repair manual?

The owner's manual in the glovebox explains the controls and the service intervals. This is the other book, the one technicians work from:

• Owner's manual: controls, warning lights, maintenance schedule, fluid types
• Factory repair manual: removal and installation steps, torque specs, diagnostic trouble codes, wiring diagrams and component locations

Your 2020 Ram 1500 is from the fifth-generation Ram 1500 (DT), built for model years 2019–2026. Years of the same generation share most procedures; equipment and electrical details still change from year to year, so the manual follows your VIN.
