Tom Besides likely made in China, I bet the bearings are not a/c specific. That is to say, I stock an a/c bearing. The difference, they have roller bearings and not ball bearings. This allows for much higher tensions demanded with a/c. You may want to consider rebuilding your pump using my a/c water pump kit. $35 w/ bearing, seal, and gasket. I can also re-build a core I have for $105. I am sure that will be more than a foreign import. I think I only have 8 a/c bearings in stock. Now is the time to order.

Upon arriving in Chicago, several guys that know a lot more than I do about the F engine noticed that the fan pulley was not lined up with the crank pulley. All suggested shimming out the fan pulley which we did by about 3/16”. I drove home and all seemed well; no belts thrown and car ran fine. After arriving home, the engine was properly broken in and I began to increase the speeds I drove. Shortly thereafter, the water pump failed as I slowed down from about 4,000 rpms. I did have another water pump in the trunk and I replaced it. Within 50 miles, that water pump failed while driving about 60 mph on the interstate, taking out the radiator. So, I bought a NAPA replacement water pump, replaced the water pump with failed bearings, had the radiator repaired and installed, cranked it up and it idled nicely for about 30 minutes, at which time I shut it down. Upon start-up, the new NAPA water pump failed. I am at a loss at what to do. The belts are not too tight. My only thought is that shimming out the water pump may have put too much stress on the water pump with a fairly heavy fan/clutch assembly. Any other suggestions?? I can’t afford another radiator rebuild and I am afraid to drive the car any distance. I can’t understand why I could drive the car nearly 1,000 miles with the shimmed out pulley, yet I can’t keep a water pump operating without the bearings failing. Help!!!
