About 6 weeks ago, I purchased a rebuilt water pump from Advance Auto Parts chain. This was the type with the white impellers. Upon getting in my car this morning, I noticed water underneath my car. I popped the hood and found the the coolant resevoir was empty! Filled it up and started the car to check where the leak was. Well the leak was from the water pump!!!
I took off the pump and exchanged it under warranty for a new one (black impellers) that they had in stock for no additional charge. Put this unit on and so far there are no leaks.
I am quite surprised that this water pump failed after only 6 weeks!
Sheessh!
