The original pump in my car, built 4/97, had the white impeller. My experience in dealerships was that the impeller blowing apart problem did not continue into the 98 model year. But like I said, if you need peace of mind, change it anyway. I changed mine for Justin (Justin Case). I changed it at about 80,000 miles. The replacement pump is still there and I just turned 230,000 miles. I replaced it with the Motorcraft replacement.
