So bought some time ago and had two problems from day one. so I decided to finally give an update. First, the shaft that the pulley is mounted on only slides 3/16" in and out of the pump housing with my calipers before installation. My old 172k pump worked less than twice that. Second, it was NOISE. It was installed with ALL NEW COMPONENTS. (rack and pinion, lines, coolant, fluids, everything.) It still has the sound of air in the system when it doesn't. Not a single bubble. What I will notice…
