2020 Genesis G80 Service and Repair Manual

This factory service and repair manual for the 2020 Genesis G80 reaches across three gasoline engines in a single four-door sedan: the turbocharged 3.3L DOHC V6, the naturally aspirated 3.8L DOHC V6 of 231 cubic inches and the naturally aspirated 5.0L DOHC V8. Three trims, 3.8, 5.0 and Sport, sit on top of that. The practical effect is a book with one body and chassis to describe and three separate engine sections, each carrying its own specifications, torque figures and diagnostic values.

Known issues on the 2020 G80. Two recalls are on the federal record for this model year. One describes a short circuit inside the anti-lock brake control module that can start a fire in the engine compartment, parked or moving. The other describes a left turbocharger oil feed pipe that deteriorates and leaks oil where the surrounding parts are hot enough to ignite it. Both point back at material the manual covers directly: the brake control module with its wiring diagrams, connector views and fault-tracing steps, and the turbocharger oil supply with its routing, sealing and torque specifications.
