2004 Toyota Sienna Service and Repair Manual

This factory service and repair manual is built around the 2004 Toyota Sienna specifically — the 3.3L V6 (3MZ-FE) and the trim your van left the plant in — so each specification and tightening sequence in it is the figure Toyota published for this model year, not one carried across from an adjacent one.

Known issues on the 2004 Sienna. Eight recalls are on file with NHTSA for this vehicle. One covers the automatic transmission, where the shift lever can be moved out of the Park position without the brake applied. A second covers the accelerator pedal: with the retention clip for the floor carpet cover missing, the accelerator pedal can become stuck, which could result in a vehicle crash. A third covers the gasoline fuel tank assembly — if the fuel tank becomes damaged and fuel leakage occurs, a fire may result. On the engine side, the belt for the power steering pump may become detached from the pulley. A seat belt recall covers the middle-row shoulder belt binding in the bezel trim piece, which can leave extra webbing in the seat belt. A structural recall covers a cable that may break due to excessive corrosion, allowing the spare tire to separate from the vehicle. The remaining two are labeling recalls: on one the GVWR is insufficient for the load carrying capacity of the vehicles, and on the other a driver may overload a vehicle, which may increase the risk of a crash. Owners have filed 2,588 complaints against this model year and Toyota has issued 145 technical service bulletins.

Whether the job is a shift lever that leaves Park without the brake, a power steering belt that has come off its pulley, or scheduled service on the 3.3L V6, the figure you work to is the one Toyota wrote for this van.
