Why such a difference in price. Is the GM worth 4 times the NAPA brand. Both are new for a 2003 Buick ParkAve Ultra with 95k miles. 1st time we're replacing the water pump.
I would go with the NAPA one, the GM one that is on the car now did not last forever either, I have had very good luck with after market water pumps for GM vehicles. 4 hours seems a little steep though......Good luck
It depends on which pump you are getting from napa the reman pump or the new pump also that is not the only thing that you will need! you will also need the plastic elbows that go from the water pump to the alternator bracket (as soon as they are touched they will break into a million pieces) there are 2 elbows in the Dorman/help bubble pack both will be needed (they aren't very expensive though) And yes the 4 hours is fine (my database calls for almost 5 hours (4.8) that's because it's an Ultra (supercharger is an interference when accessing the pump) So continue with what you are doing just be sure to get the NEW pump from NAPA
