FAQQuestions about the 780 manual
Which 780 years does this manual cover?
Every year from 1987 to 1991 — 5 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 Volvo 780 manual or an aftermarket guide?
The OEM version. It carries the procedures, specifications, torque values and wiring diagrams Volvo published for the 780, organized by system — not a condensed aftermarket summary.
Does it include 780 wiring diagrams?
Yes. Full wiring diagrams are part of every 780 manual, alongside repair procedures, specifications and diagnostic information.
Does the manual cover 780 recalls?
7 recalls are on federal record across the 1987–1991 780, 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 Volvo dealers.
Why do some 780 years cost more?
Every 780 year is $29.99.
Is this a subscription?
No. One payment, and the manual is yours to keep — unlike per-vehicle subscriptions that renew every year.
How do I get the manual after purchase?
It is a digital manual — nothing ships. Access details arrive by email right after checkout, and you can use it on any device.
