Changing a power steering pump on your car can be a daunting task, but with the right tools and instructions, it’s not too hard. In this article, we’ll show you how to change the pulley on a power steering pump in a car, using both the manual and automatic methods.
Identification of Pulley
Pulley identification can be tricky, especially if the pulley is damaged or has lost its shape. Pulleys typically have a number stamped on them, and this number will help you identify it correctly.
If you cannot find the number on the pulley itself, you can use a pulley wrench to turn the pulley. The position of the teeth on the wrench should correspond to the markings on the pulley. Use extreme caution when doing this, as turning the pulley too far can damage it.
Removal of Pulley
If your power steering pump is leaking, it’s time to replace the pulley. This DIY guide will show you how to remove the pulley on a 2001-2007 Ford F-150.
1 Locate the power steering fluid (PSF) reservoir. It is usually located behind the front grill or in the engine compartment.
2 Remove the release valve from the PSF reservoir.
3 Disconnect the power steering line from the PSF reservoir.
4 Raise the hood and locate the pulley on the power steering pump. There may be two pulleys, one on each side of the motor. The pulley on the left should be easily removable by hand. The pulley on the right mayrequire a wrench to loosen it. If it is too tight to remove with a wrench, use a impact gun or instrument drill to break it loose.
5 Carefully remove the old pulley by hand or using a wrench if necessary. Save any old seals and gaskets for reuse. Replacethe new pulley and reattach everything according to instructions in Step 4.
Replacement of Pulley
If you are experiencing difficulty with your power steering pump, it may be time to replace the pulley. Replacing the pulley can be done by yourself or a mechanic and is relatively easy. Here are some tips on how to do it:
1. Disconnect the power steering lines at the pump.
2. Remove the bolts that hold the pump cover in place.
3. Carefully remove the old pulley from the motor shaft.
4. Clean and lubricate both the motor shaft and new pulley before installation.
5. Install the new pulley onto the motor shaft, making sure it is oriented correctly and lined up with the grooves in the shaft.
6. Replace the bolts and secure the pump cover back on to the pump.
Reinstallation of Pulley
If your car’s power steering pump is failing, and you need to replace it, you’ll need to remove the pulley. This guide will show you how to do it.
1. Park the car on a flat surface.
2. Remove the wheel cover and tire.
3. Remove the four bolts that hold the power steering rack to the car.
4. Remove the power steering pump cover.
5. Disconnect the electrical connector at the pump end of the belt (or chain).
6. Loosen the three bolts that hold the belt on the pulley (2 on each side).
7. Carefully loosen the bolt that secures the pulley on its shaft (1 in front and 1 in back).
8. Pull off the old pulley and replace it with a new one from your parts bin or dealer. Tighten all bolts in reverse order, making sure they’re evenly torqued (22 ft-lb in total).
9. Reconnect all wires and replace the pump cover. Torque bolts to 12 ft-lb (19 Nm).
