2008 Toyota Sienna Service and Repair Manual

Fitment is the point here: this service and repair manual is built around the 2008 Toyota Sienna specifically, the 3.5L V6 (2GRFE) it left the factory with and the trim on your door jamb, so every clearance and tightening sequence it quotes is the number Toyota published for the 2008 van rather than one carried over from an earlier Sienna.

Known issues on the 2008 Sienna. Seven recalls sit on the federal record for this model year. One covers the automatic transmission, where the shift lever can be moved out of the Park position without the brake applied. A structure recall covers a cable that may break due to excessive corrosion, after which the spare tire may separate from the vehicle. Four more concern labeling and load capacity: on one, the GVWR is insufficient for the load carrying capacity of the vehicles; on another, incorrect load carrying capacity modification labels could result in the vehicle being overloaded; a Southeast Toyota campaign warns that a driver may overload a vehicle, which may increase the risk of a crash; and a Gulf States Toyota campaign covers vehicles that do not meet the requirements of Federal Motor Vehicle Safety Standard No. 110, Tire Selection and Rims. The last covers the front seat heater, where a damaged copper strand heating element may short circuit, increasing the risk of a fire. Owners have submitted 570 complaints for this model year and Toyota has issued 115 technical service bulletins.

Whether you are chasing a Park-position shift complaint, inspecting the spare tire cable for corrosion or tracing a seat heater circuit, it keeps you on Toyota's procedure and the figure written for the 2008 Sienna.
