New water pump 6 impellers whats up with that!

I will. I ordered one from Oreillys last week and it was suppose to be an 8 vane but it was substituted with a 6. I'm being told that they are redesigned and all are 6 vane. I'm still uneasy about using a 6. Will keep ya posted. The one I ordered Monday is going to be shipped from Cardone......we will see. I'm wondering if anybody here is already using a new 6 vane on an A/C car. Chime in please.
