I just bought my first Taurus, a '99 with 72000 miles and the Vulcan engine, and I am going through it changing, oil, fluids, etc. I have a question about the Taurus water pumps. This vehicle is cooling fine, there is no leakage from the pump, and no noise when listening to it with a stethoscope. But when I try to wiggle the pump belt pulley (with the serpentine belt removed), I can get a tiny bit of movement. I have to really force it, and the movement is so slight that I first thought I was imagining it, but it is there.Should I replace the pump? I'm asking your advice and opinions for two reasons: (1) I'm not familiar with the 3.0 Vulcan engine and water pump longevity on it. (2) I've had an increasing number of problems over the years with getting replacement parts that are defective, going to much time and trouble to put them in, only to find that I'm worse off than I was before doing the work. Any help will be appreciated. And thanks.
