Hi,
It's pretty straight forward but you'll definitely need some space in order to remove it from the engine so the first thing I do is to remove the passenger side crash bar, the wiper fluid reservoir and put aside the fuse box on the strut tower. That gives enough space to work.
Remove the serpentine belt also with a 15mm hex socket.
Jack the car with approved jack stands and remove the passenger side front wheel.
Using a set of pliers remove the clamp from return line on the pump reservoir, be ready as fluid will start spilling.
Remove the high pressure hose from the pump with a flare nut wrench. Open end wrenches are good too but you have more possibilities to damage the nut on the high pressure line.
Rotate the power steering pulley so one of the holes on it matches the 12 and 6 o'clock positions in order to remove each one of the 2 bolts holding it to the engine (I think they are 1/2 inch heads).
Remove the pump.
Remove and install the pulley with a steering pump pulley remover, some autoparts stores will do it for you when you buy the new pump.
Installation is reverse of removal. Tighten the high pressure line to 56 ft/lb and the mounting bolts to 20 ft/lb with a torque wrench.
This would be a good time to flush your power steering system. Put both front tires in the air and rotate the steering wheel while the lines are dettached; while turning the wheel, fluid will start coming out from the return line, I think 4 or 5 times will get the entire fluid out.
After you install the new pump bleed the system before you start the engine. Again, with both tires in the air, turn the steering wheel with the reservoir cap removed about 20 times from side to side without hitting the stops while checking the fluid in the reservoir is at the COLD MARK. Start the engine and let it idle for some minutes while you keep turning the wheels and checking the fluid level. Check for any leaks and once the engine reaches normal operating temperature check the fluid again, it should be at the HOT MARK.
I think that's pretty much it, if I'm missing something please let me know!
Don't forget to torque the wheel lug nuts to 100 ft/lb.
Good luck!
