Review on ACDelco 252 845 Professional Water Pump: Optimal Performance & Durability by William Wiley

Failed. Shaft leakage after 8 months. Yes, at the same time I replaced the belt, tensioner pulley and fan clutch. I was trying to find a way to return it as I needed to buy it from O'Reilly quickly. Very disappointed that Delco's AC part failed so quickly. There is no way to go back to my previous orders. AC Delco will replace it, but I need to take it to the dealer and 'diagnose' it. Then they do the $$$ job. Ridiculous. What's the point of doing it yourself if you have to go to the dealer to replace the broken part? That's the whole point of doing it yourself. In addition, the bearing in the belt tensioner has failed and must also be replaced. Update: Revain refunded me about 90‰ of the original price. Amazing customer service from them.
