1999 Ford Taurus his having problems with the power steering First the power steering fluid go low and foam when on and overflowing out of the top of the cap?

Answer 1

The fluid is burnt and has been overheated or in service too long. You may come out by draining the fluid from a hose connection at the lowest point of the PS system. Close drain. and refill with Transmission Fluid. Idle engine for 20 minutes and ocassionalyy turn steering wheel full left and right. any improvement? Drain fluid again and fill again with trans fluid, Improved? Replace with PS fluid. I've used transmission fluid in my Chevy van PS for twenty years but can't say you should do the same.

THE FLUID DID NOT TURN BLACK IT HAS TURNED TO A LIGHT COLOR PINK BUT THE OTHER PROBLEMS YOU HAVE DESCRIBED IS DEAD ON. I WILL TRY WHAT YOU HAVE PRESCIBED. I WILL POST THE RESULTS WHEN I CORRECT THE PROBLEM.

what ever you do DONT use tranny fluid in the Power Steering you must use PS fluid only unless you want to go through the proces of flushing your whole system repetedly because if any transmission fluid gets mixed with your PS fluid it becomes foamy and you will then have air in your lines.

Ford specifically specifies Mercon V transmission fluidfor use in the power steering system.
