A while back, I installed an O'reilly brand water pump on my Toyota. The pump was made in USA and the casting looked fine. I installed it and used OEM red coolant. Well, 20K miles later, it leaking out the weep hole and getting worst. Since the pump is driven by the timing belt, I decided to skip using the O'reilly warranty and get good parts. I have a friend at a shop that I can get all the parts at a discounted price.
I got Mitsuboshi belt, NTK bearings, THO and Stone cam/crank seals. (All made in Japan)
I wanted a Aisin water pump but they were out of stock. So I had them order a NPW (Nissan Pump Work) instead since it's also made in Japan. I should have the parts by Tuesday. I search on BITGO, forums, and Amazon and many show NPW to be a reliable manufacturer but not much more. I was wondering if anyone can share any experience with NPW water pumps.
Thanks
