Has been working fine since installing it a week ago. This appears to be a better repair than the one I got from a well known national auto parts chain that was noisy from day one and broke completely after a few months. The reservoir on the Cardone pump was slightly larger than the factory reservoir and I had to grind the oil pressure sensor bushing so it could slide over the oil pressure sensor so I could tighten the sensor properly. Overall I find the remanufactured Cardone pump to be excellent quality and they offered a big discount on my core. I am happy with this purchase!
