New to the group! I installed a new AC Delco Gold water pump from Rock Auto on my 99' K3500 w/454 along with a bunch of other repairs and upgrades over the past 2 weeks. Finally taking it for a ride last night (mind you it has had a couple hours of idle time and a few heat cycles prior to driving) and to my surprise, about 5 minutes into my drive the left side of the pump cracked and spewed all my coolant out, thankfully not far from home. Rock Auto will accept a warranty return on the pump since it was purchased only 3 weeks ago, but I don't know if I want to install another one of the AC Delco pumps. I've had and have worked on many small and big block Chevys and have never had this happen. The block surfaces were super clean before install and the bolts were snugged before tightening. Anybody have this happen before? Anybody have a reference on a different/better pump? Rock Auto also sells the GM Genuine pump for $228. That is an option as well. Thanks in advance!
