I ordered this new pump to replace my original 96 Dodge Ram 1500. The original pump still worked perfectly but had 354,000 miles on the odometer. As a mechanic, I just didn't want to risk it failing outside of town. The part fitted perfectly, but I also installed a new pressure line, also to the liquid cooler. Don't whine or run. A good product. My model requires power steering fluid, NOT ATF4. Remember. I chose Lucas power steering oil.
