2022 Chevrolet Camaro Factory Service Manual: How to Access the Real Thing

ByKenji Alvarez

GM stopped printing the shop manual — here’s where it lives now

Search helminc.com for a 2022 Camaro shop manual and you’ll find only the owner’s manual. That’s not a gap in Helm’s inventory; it’s GM policy. Chevrolet phased out printed factory service manuals for current-generation vehicles. The full repair content migrated to an online portal called GM Service Information — SI for short — and that’s where the authoritative data lives now.

GM Service Information (SI): the actual factory source

SI is the same database dealership technicians open when your car is on the lift. It covers every GM vehicle by VIN, returning build-specific repair procedures, wiring diagrams, torque specs, and technical service bulletins. For a 2022 2SS convertible, that means LT1-specific content — not generic V8 data that may or may not apply to your actual car.

Access is subscription-based through ACDelco’s Technical Delivery System at acdelcotds.com. Pricing tiers allow short-term access without committing to a full year: a three-day subscription runs $20, a one-month pass is $150, and an annual subscription is $1,200. If you have one big project coming up, the three-day tier is worth knowing about.

One practical limitation: SI is entirely browser-based. No PDF export, no offline copy. You need a stable internet connection in the garage, or you’ll be taking notes at the desk before going under the car.

What Helm Inc. still carries for the 2022 Camaro

Helm Incorporated has been the authorized source for printed GM service manuals for decades. Their multi-volume shop sets for earlier Camaros — through the 2018 model year — are still listed and legitimate. For 2022, their Camaro page returns only owner’s manuals and supplement documents. No shop set.

This matters if you’re browsing eBay or forum classifieds. Any listing claiming to be a factory printed shop manual for a 2022 Camaro is almost certainly a third-party printout of SI data, not a Helm-published volume. Not necessarily wrong, just not what the label implies.

Third-party alternatives

Haynes

Haynes publishes a repair manual covering the sixth-generation Camaro from 2016 through 2023. In-book coverage focuses on the 3.6L LGX V6 and 6.2L LT1 V8; additional coverage for the 2.0L LTG turbo and 6.2L LT4 is available through their online companion. For routine maintenance, brake work, sensors, and basic diagnostics it covers the necessary ground. It does not go deep on transmission rebuilds or complex electrical tracing.

Mitchell1 and AllData

Both platforms are used by independent repair shops and include GM factory content. They’re priced for professional use rather than individual owners, but if GM SI access is difficult in your region, or you already have a shop-level subscription, either is a legitimate alternative.

PDF downloads from third-party sites

Plenty of sites sell downloadable PDFs labeled as factory service manuals. Quality varies sharply. Some are genuine exports from SI; others are repackaged Haynes or Chilton content. Before buying, confirm the document explicitly covers the 2022 model year and your specific engine. A procedure pulled from a fifth-generation document is not safe to follow on a sixth-gen car. Verify first.

Matching the source to the job

For occasional DIY work — brakes, fluids, sensors — the Haynes manual handles most of it. When the job demands factory-level depth, a short GM SI subscription is the right call. If you’re planning sustained wrenching over the life of the car, the annual subscription makes more sense than stacking short-term passes. The printed factory shop manual, in the traditional multi-volume sense, simply does not exist for the 2022 Camaro.
