Gracey uses Lucas Power Steering Stop Leak in 1995 Mercury Villager

My 1995 Villager with 320,000 KM on it started to develop a sqealing sound in the Power Steering pump. I thought it was just the -20 C Cold weather we were having since the sound would go away after a few KM of driving. But I had it checked out and they said there were no leaks and the belts were fine so they added Lucas Power Steering additive to the existing fluid. And the sound went away as well as improved the feel of steering at cold tempuratures.
