Is the power steering pump bad if you hear a squealing noise when turning a 1993 Honda Accord hard?
It may need just a simple belt replacement. If you change one, change them all.
Honda Accords are equipped with a hydraulic assisted steering system. The rotation of the motors crankshaft also drives the vehicles accessory belt system. The belts drive the power steering pump which pressurized fluid into the steering gear. The turning of the steering wheel actuates the rack-and-pinion to move right of left. The hydraulic pressure assists the gear in this movement. Without this pressure assist turning the steering takes much more force.
The power steering pump is located just above the alternator on the drivers side of the car. An easy way to locate it on a 1991 Honda Accord is to first locate the dipstick for your oil, then directly next to it is a pulley, this pully is mounted on youyr power steering pump, and is your power steering pump pulley.
