2015 Toyota 4Runner Service and Repair Manual

The 2015 Toyota 4Runner ran a single engine across the range, the naturally aspirated 4.0L V6 (1GR-FE), so the torque specs, clearances and diagnostic thresholds hold whether the truck in the bay is an SR5, a Trail, a TRD Pro or a Limited.

Known issues on the 2015 4Runner. NHTSA lists five recalls against this vehicle. Gulf States Toyota recalled 4Runners over an incorrect label, which may result in the vehicle being overloaded, increasing the risk of a crash. Southeast Toyota Distributors accounts for two: one on the exhaust system, where contact with an exhaust tip may result in personal injury, and one on accessory hood scoops, where if the hood scoop detaches, it may become a road hazard, increasing the risk of a crash. Toyota Motor Engineering & Manufacturing covers the other two — the passenger-side frontal air bag inflator module, where an inflator explosion may result in sharp metal fragments striking the driver or other occupants, and the gasoline fuel pump, where if the fuel pump fails, the engine can stall while driving, increasing the risk of a crash. There are 116 owner complaints on record for the year and 168 technical service bulletins.

Chasing a stall complaint, inspecting the passenger air bag inflator module, or setting up a scheduled interval on the 4.0L V6 — the procedures and specifications here are the ones Toyota wrote for this 2015 4Runner.
