FAQQuestions about the R20 manual
Which R20 years does this manual cover?
Every year from 1987 to 1988 — 2 separate manuals, one per model year. Pick your year in the selector; the manual you receive is matched to that exact year, engine and trim.
Is this the OEM Chevrolet R20 manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Chevrolet published for the R20, organized by system — not a condensed aftermarket summary.
Does it include R20 wiring diagrams?
Yes. Full wiring diagrams are part of every R20 manual, alongside repair procedures, specifications and diagnostic information.
Does the manual cover R20 recalls?
2 recalls are on federal record across the 1987–1988 R20, listed by year below. The manual carries the manufacturer's diagnostic and repair procedures behind the systems involved; the recall repairs themselves are performed free by Chevrolet dealers.
Why do some R20 years cost more?
Every R20 year is $29.99.
Is this a subscription?
