I have a 22 year old Buick with the body in excellent shape for its age and maintenance has been quite reasonable to-date. Power steering failed last Friday and it looks like pump, cooler and pressure hose need to be replaced according to dealership. The car otherwise works well and is quite comfortable and cheap to run. I was hoping to keep it at least till next year. Is there any way to prolong the life of the PS for a few months without replacing above parts? I topped it up and it works fine but I am sure that will not last indefinitely. It seems to be losing ps fluids slowly as I do not see much of a leak in garage after overnight parking.
