Boycotting AC DELCO
While I understand,and sympathize with your frustration. I've found AC Delco parts to have a far,far better track record than any other manufacturer/re-builder. I'd be pissed off too,but what are my options? Start using A1-Cardone parts? I would have returned the part. Mechanical waterpump issues have been a thing of the past since I installed an electric one 15-16 years ago. Replaced one 8-10 years ago,but it had not failed. I kept it for a spare,and haven't needed it yet. Longevity of electric pumps are substantially greater. Plus,one can be swapped out in a matter of minutes. One no longer has shaft alignment issues,or weep hole leaking issues for that matter. Probably the two most common water pump problems...
