Just replaced the water pump on my 02 Grand Prix (3.8 L motor) and was comparing it to original water pump... new one (from China of coarse) design did not look as good as old one. Replacing the one on my 03 Buick Regal (3.8 L motor) but was wondering if there was a better quality pump out there or nicer high flow pump. The one for the Grand prix was an AC Delco from APC for $60. I think I should spend a little more for such an important part? Any ideas/info?
