Parts
- Power steering pump pulley × 1 — Use OEM specification
- Power steering fluid × 1 — Toyota ATF Dexron III
Fluids
- Toyota ATF Dexron III — 1 qt
Preparation
- Ensure engine is completely cool to the touch
- Park vehicle on level ground and engage parking brake
- Disconnect negative battery cable
- Remove engine splash shield and right front wheel well liner for access if needed
- Use fluid transfer pump or turkey baster to remove as much power steering fluid from reservoir as possible into drain pan
Procedure
- 1Remove serpentine drive beltLocate the serpentine belt tensioner on the right side of the engine. Using a 14mm wrench or serpentine belt tool, rotate the tensioner clockwise to release tension. Slide the belt off the power steering pump pulley first, then carefully release tensioner and remove belt from remaining pulleys. Note the belt routing for reinstallation.
- 2Access power steering pump pulleyThe power steering pump is located on the right side of the engine below the alternator. Verify clear access to the pulley face. If additional clearance is needed, you may need to remove the right front wheel and wheel well liner for better access from below.
- 3Install pulley puller toolThread the power steering pulley puller tool into the threaded holes on the face of the pulley. The tool should engage firmly with the pulley. Some pullers use a center bolt that presses against the pump shaft while the outer portion pulls the pulley. Ensure the tool is properly seated and aligned before applying force.
- 4Remove pulley from pump shaftCarefully turn the puller tool's center bolt clockwise to pull the pulley off the pump shaft. Apply steady, even pressure. Do not use impact tools. The pulley should release from the shaft taper with moderate force. If excessive force is required, stop and verify tool is properly installed. Remove pulley and puller tool once released.
- 5Inspect pump shaft and new pulleyExamine the pump shaft for damage, scoring, or debris. Clean the shaft with a lint-free cloth. Inspect the new pulley bore for cleanliness and proper fit. The pulley should slide onto the shaft with minimal resistance but not be loose. Do not lubricate the shaft or pulley bore as this is a press-fit taper connection.
- 6Install new pulley onto pump shaftAlign the new pulley with the pump shaft and slide it on as far as it will go by hand. Install the pulley installer tool, which uses a center shaft that threads into the pump shaft while the outer portion presses against the pulley face. Verify the pulley is starting straight onto the shaft and not cocked at an angle.
- 7Press pulley onto shaft to proper depthTurn the installer tool's center bolt clockwise to press the pulley onto the shaft. Press until the pulley is fully seated with the front face flush with the end of the pump shaft, typically when pulley face is 0-1mm from the pump housing reference point. Do not over-press as this can damage the pump bearings. Compare installation depth to the old pulley if available. Remove installer tool.
- 8Reinstall serpentine beltRoute the serpentine belt around all pulleys according to the belt routing diagram (typically found on a decal under the hood or in the service manual). Leave the power steering pump pulley for last. Rotate the tensioner clockwise and slip the belt onto the power steering pump pulley. Carefully release the tensioner to apply proper belt tension. Verify belt is properly seated in all pulley grooves.
- 9Refill power steering fluidAdd Toyota ATF Dexron III power steering fluid to the reservoir until it reaches the COLD MAX line. Start the engine and turn the steering wheel slowly lock-to-lock 5-10 times to purge air from the system. Check fluid level and add as needed. Repeat until fluid level stabilizes and no more bubbles appear in the reservoir.
- 10Check for leaks and proper operationWith engine running, inspect the power steering pump, pulley area, and all connections for fluid leaks. Listen for unusual noises from the pump. Turn the steering wheel lock-to-lock while checking for smooth operation without whining or groaning. Recheck fluid level after test and top off if needed.
Reassembly
- Reinstall wheel well liner and splash shield if removed
- Reconnect negative battery cable
- Reinstall right front wheel if removed and torque lug nuts to specification
- Dispose of used power steering fluid properly at a recycling center
Verification
- Start engine and verify serpentine belt runs smoothly without slipping or squealing
- Turn steering wheel fully left and right multiple times, confirming smooth operation without noise
- Check power steering fluid level is at COLD or HOT mark depending on engine temperature
- Verify no fluid leaks around power steering pump or pulley area
- Test drive vehicle and confirm power steering assists properly during turns
- Recheck fluid level after test drive and top off if necessary
