Hey guys my Mustang has been making noise while steering and after some research I have concluded that my power steering fluid is bad. Instead of draining all the old fluid and putting in new fluid, I read that one could use an alternative method by using a syringe to suck the existing power fluid out of the reservoir and putting new fluid in then drive around for a bit until the fluid looks bad again and repeat the process until all the fluid is replaced with new fluid. Have any of you done this? Is this a good idea?
