Taz, Cory is right about the info at ls1tech. Check it out. I would not worry about the bearing issue. We are talking about a small number when compared to all the units sold. I was not upset about the bearings anyway, just Mag's lack of assistance and not standing by their product in this case. On the otherhand, other's have been taken care of. For instance, LPE had a 'vette with a bearing problem just weeks before I did and Mag took care of that one.
As for the fans, mine have been gone since Paragon. They were twin Flex-a-Lite fans. I think they were 15". That's what BKLYN and I were hooking up in this pic. The problem was the blades, not the motor. The blades just sheared off against the resistance of the water. I dare say you could just turn them right back on.
The fan on the left here was missing one blade and later shed most of the rest. I made it 6 hours home with 1 1/2 fans and no overheating.
