How do you replace a power steering belt on a Toyota Sienna?

Answer 1

This applies to 2004 Sienna XLE

Just did this today since sometime in the past, someone installed the belt with the flat side toward the grooves! Lost Power Steering, luckily it was in the driveway and not on the highway. The 4 peak belt had shredded into a 2 peak belt + a 1 peak belt. Flipped them in place a week ago as a bandaid, replaced both belts today.

You will have to remove the serpentine belt to replace the power steering belt, so you might as well replace both at the same time.

Steps:

# Turn off van # Set parking brake # Chock left rear wheel # Jack front right corner of van using the recommended jacking point as you will be removing the front right wheel and will need free access to the engine behind where the wheel sits. # Remove front right wheel # Remove 2-10 mm head screws holding a plastic shroud piece in the inner fenderwell, covering the belt area. # Open hood if not already open.

# Mark serpentine belt tensioning screw to ensure correct tensioning if replacing belt with exact same belt length.

## 14 mm head screw at the top of the alternator ## 12 mm golden screw below tensioning screw (I removed mine but it might not be necessary).

## 12 mm tensioning block lockdown screw ## 12 mm tensioning screw. The tensioning screw will likely need to be loosened almost all the way to get the serpentine belt off and the new belt on. Loosening this is best done with extensions and a universal joint.

# Detension the main serpentine belt by loosening 4 screws. (Passenger side of engine, accessed from open hood):

# Remove serpentine belt # Relocate yourself to the wheelwell. # Locate the tensioning link between crankshaft pully and the power steering pump. # Mark the location of the washered screw in the groove of the tensioning link to ensure correct tensioning if replacing with exact same belt length. ## 12 mm washered tensioning link bolt ## 12 mm tensioning link lockdown bolt (at the bottom of the link). # Loosen 2 bolts: # Using a 12 mm socket of appropriate length attached to a socket wrench, rotate the power steering pump to relieve the tension on the belt. # Remove power steering belt # Replace power steering belt # Work steps 1-15 in reverse, checking tension (no more than 1/4" play in any belt) to reassemble.
