If your water pump has already been replaced with a steel impellor type ?
I bought my 92 525im with 95k and no records. So, based on the boards good advice...I want to make sure of this one before she blows!
P.S. Yea, I know...I can just spend the time and money to do it, and then I'll know for sure. But I'd like to find out if there's an -external- visual identification.
