HI V8 FORD MEMBERS was wondering if anybody else experienced this problem, years ago I replaced both my water pumps, and these were did not have a lot of mileage on them, I used the pumps from a well known rebuilder, I used water wetter and used water from a dehumidifier so has no chemicals and water pump lube, FYI I do not know how many years, or miles they were used, Originally When I RESTORED the car replaced both pumps, they did not give me any problems for 30 years, but seem to run hot, so wanted to try a more advanced set,to see if I would get better cooling, this sneeked up on, me a little at a time, I developed a vibration in the car, rebalenced the wheels, vibration was still there, every once a while I noticed I had a rattle noise when starting the engine, the vibration in car, like the floor [not in the steering wheel it seems ], was after 45 mph got real bad after 50 55 mph then last summer I was a cruise . keeping it around 40 , 50 or so miles trip on the way home at a light I took off and the engine seem to lock up for split second. then cleared up. I made it home, and checked the water pumps, by looking at them the LS had a wobble,with engine running at a idle now the engine was warm once the engine cooled off, the pump had NO play ??? AND PUMPS NEVER LEAKED I removed both pumps and found a built up a white powder cake on the impellers I replaced both pumps with new one from BOB DRAKE seem like they are more advanced in design, then what I had any body else had this problem ? I hope the VIBRATION in the 37 will be gone, will be out in the 37 very soon, and see if the new pumps make a difference, I will post a few photos soon, PHOTOS POSTED I used a endoscope in the top of radiator ,that also has the white cake,soon as I get a chance I am going run cleaners though the cooling system and take photos to see what it looks like cleaned, with the radiator hoses off the heads, does not seem to have the white cake ? will let you know what I FIND out, THANK 37 Ragtopman , MAINE
