Where do you add power steering fluid on a 2003 Pontiac Bonneville?
To replace the power steering unit on a 1993 Pontiac Bonneville, start by disconnecting the negative battery cable and draining the power steering fluid. Remove the serpentine belt and disconnect the hoses from the power steering pump. Unbolt the pump from its mounting bracket and replace it with the new unit, ensuring all connections are secure. Finally, refill the power steering fluid, bleed the system to remove any air, and reconnect the battery.
The power steering reservoir is underneath the alternator by the firewall.
The Pontiac Bonneville used the same power steering fluid from 1992 until 2005. You should look for GM Power Steering Fluid with part number1050017 for quart sizes or part number 1052884 for pint sizes.
It is on the left side of the engine back by the firewall.
This is two of the things I know that could be wrong. The power steering pump is either bad or there is no power steering fluid in the pump causing it to have steering problems. Be sure to check the fluid level in the power steering pump.
No, you don't have to remove the power steering pump to remove water pump. You do have to loosen the 2 screws that hold the power steering pump and then move power steering pump about an inch or so, so you can have access to some of the screws that hold the water pump on.
Behind the strut support bar, behind and under the alternator is the power steering cap. It is difficult to get to. Good luck!

Probably at the power steering pump. You will find that at the side of the engine that has your drive belts, most likely at the passenger's side and toward the back and top of the engine.
take off serpentine belt unbolt powersteering pump and hoses and drain it. That's it.
To replace the power steering seals in a 2004 Pontiac Grand Prix, first, safely lift the vehicle and remove the power steering pump from the engine. Drain the power steering fluid, then disassemble the pump to access the seals. Replace the old seals with new ones, ensuring they are properly seated, and reassemble the pump before reinstalling it. Finally, refill the power steering fluid and check for leaks while turning the steering wheel to circulate the fluid.
