Well, I would recommend purchasing Power Steering pumps from U-Haul because they offer a variety of products and services for an incredibly reasonable price.
Check power steering fluid. If it is good, probly need a new PS pump.
You will need to remove the power steering pump belt in your 1997 Chevrolet Express. Remove the power steering pump hose. Remove the power steering pump retaining bolts. Reverse the process to install the new power steering pump.
I'll be civilized and answer this. The power steering pump is a hydraulic pump that needs fluid to pump so it can move the power steering gear. Simpler said no fluid no power steering. Hope you are not offended.
I need more information
A power steering pumps as much as the power steering pump can pump.
You will need a pump, pump brackets, pulleys, belt, hoses, a power steering box and all the nuts and bolts. A doner vehicle would be good to have.
Remove the power steering pump hose. Remove the power steering pump belt. Remove the power steering pump retaining bolts. The power steering pump will come off.
Most times you simply replace the power steering pump. Good Luck
The squealing could be that you need to add power steering fluid. Also you should check the belt that operates the power steering pump, if bad replace it. If the power steering pump is full and the belt is ok, then you may need to replace the power steering pump.
Secure the power steering pump with the retaining bolts. Attach the power steering hose to the power steering pump. Put the belt on to the power steering pump. Fill the power steering system with fluid.
YES. your power steering pump is a hydraulic pump that pushes fluid through lines to make your wheels move. hydraulic fluid such as ATF or POWER STEERING FLUID is good for your power steering pump. it is a PUMP after all. OIL has the purpose of lubricating, and has very different qualities than hydraulic fluid. DO NOT put OIL in your power steering pump... put POWER STEERING FLUID or if you can't get power steering fluid AUTOMATIC TRANSMISSION FLUID will do...
Remove the belt for am your power steering pump. Remove the power steering pump hose. Remove the power steering pump retaining bolts. Reverse the process to install your new power steering pump.
