AC Delco 12703898 is the OEM grade water pump.My weep hole is leaking !
I can get a Gates 45006 or an ACDelco 252-845 for about the same $$$.
Any preferences either way ?
AC Delco 252-845 is their Gold or Professional series pump.
Go with the OEM, not Professional. It’s $40-$50 more but will give more piece of mind.
