Ideally, use a transmission flush machine.
Failing that, disconnect the return hose, then run the engine and steer back and forth until you can't do so (with the front wheels off the ground.) Repeat three times. This is more complete that a Power Steering flush from most chain service outfits.
I recommending using Dexron instead of "power steering fluid" for this vehicle. The better detergent additives and higher compressibility can keep the system going for a longer time. If, however, you've just recently (less than 6 months) replaced both the pump and the gearbox, you might be better off using Honda-compatible power steering fluid.
It is not necessary to flush the power steering system in a car. However, you should check the power steering fluid level in the car each month.
You will screw your steering system. You need to flush steering system ASAP. And of course do not drive with engine oil in steering.
Rack and Pinion with power assist.
You could get an oil change as soon as possible to flush the system.
there is no power steering fluid, this is an electric assist power steering system, is you are having problems let the experts handle this go to the dealership.
Flush it
Flush the system immediately and install the correct fluid. Oil is too thick for the PS system.
COULD BE A NUMBER OF THINGS...YOUR POWER STEERING PUMP MAY BE BAD.
you don't. Chevy cobalts are electric power steering
check power steering oil. if the oil is dirty and burnt ,yaes it needs flush otherwise no power steering does not need flushing unless there is a problem
Bad juju. Don't do it. If you've already done it, you'll probably have to have the power steering system flushed; brake fluid has significantly different characteristics from power steering fluid. Agree with above. It's pretty caustic, flush and get it out of there before you have problems.
The power steering reservoir is mounted on top of the power steering pump.
