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.
Where do you add power steering fluid on a 2003 Pontiac Bonneville?
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.
Classic sign of low steering fluid.
The power steering reservoir is underneath the alternator by the firewall.
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.
Behind the strut support bar, behind and under the alternator is the power steering cap. It is difficult to get to. Good luck!
take off serpentine belt unbolt powersteering pump and hoses and drain it. That's it.
Put it in the p/s resirvoir located on the pass side of the engine compartment under the alternator.
It's in the transmission.
Check the Power Steering Fluid level.
