A low power steering fluid condition left neglected long can accelerate pump
wear. When bringing the fluid level back up to snuff, first check the pressure
and return hoses for leakage. Next check the steering assembly or
rack-and-pinion for leaks. If everything is topped off and not leaking, yet
the pump continues to groan and whine, the damage may have already been done.
It may be time to replace the power steering pump, fluid, and flush the system
of toasted fluid. If you're one of the lucky people, removing and replacing
the power steering pump is a fairly simple task. On the other hand, some pumps
are buried in a maze of manifolds, vacuum lines, and everything else that
could possibly be put in place to prevent easy power steering pump replacement.
The power steering pump takes its power from the engine by using belts and
pulleys. V-belt or serpentine, the idea is the same. Loosen the tension on the
belt, remove and replace the pump, and put the belt back on. Depending on what
type of replacement pump is procured, it may be necessary to transfer the
pulley from the old pump to the new one. Auto parts stores rent puller tool
kits for a nominal fee. Be certain to get the kit that will work for your
vehicle. Once installed, the system must be bled of trapped air. This entire
replacement procedure varies by vehicle, so it's best to consult a service
manual if that grumpy old pump has breathed its last breath.
|Step 1 - Disconnect the battery. Release the tension on the drive belt.
This vehicle has a serpentine belt with an easy-to-reach tensioner. Your
experience may vary.
|Step 2 - Remove the belt from the power steering pump pulley.
|Step 3 - Loosen and remove the mounting bolts. Note the access holes
through the pulley.
|Step 4 - Remove the fluid pressure line. Note the O-ring. Replace all
O-rings and gaskets. Replace the hose if cracked or leaking.
|Step 5 - Remove the power steering fluid return line.
|Step 6 - Remove the power steering pump. Block hose mounting holes to
|Step 7 - Drain old fluid from the pump into a catch container. Clean
the pulley of slippery power steering fluid.Â Always properly dispose of used
oil and fluids.
|Step 8 - To remove the pulley, first install the remover according to
the owner's or service manual instructions.
|Step 9 - The pulley remover pushes on the pump driveshaft and forces
the pulley off.
