2023 Toyota 4Runner Service and Repair Manual
The 2023 Toyota 4Runner was sold with a single engine, the 4.0L V6 (1GR-FE), across a lineup that ran from the SR5 to the TRD Pro and the 40th Anniversary Edition. This service and repair manual is written to that model year, so the torque values, clearances and diagnostic steps in it are the ones Toyota published for the 2023 truck rather than figures carried over from an adjacent year.
