    My neighbor several years ago on a 2004 Trailblazer had one that seemed to make a noise from the fan area and the fan seemed to have too much slop, so i ordered one from Rock auto but the slop was ultimately found to be caused from a bad water pump bearing, yet there was no coolant leakage going on.
