Since I still have the front bumper cover off my car I just went out to see what it said on it. I seen Bosch stamped into the impeller housing, other than that the bracket just has some numbers. I think I'm just leave the stock pump on for now, I believe the slower pump may work better with the fans that I'm installing on the heat exchanger. I'm still waiting on the fans and tempeture gauge to be delievered that ordered 1/14/08, I've got the remote relay & wiring for the fans installed yesterday.
