Review on 🔧 Optimized ACDelco Professional Water Pump Kit Model 252-693 by Rubeen Black

This really is the best water pump you can buy for 3800 engines It has larger fins than the OEM water pump. I used the Mini Scaper blue polycarbonate scrapers to remove the old gasket and it did a very good job (no scratches on the engine block). The blades worked best when wetted with coolant. I used a Fel-Pro 35351 seal in place of the one that came with this water pump and lubricated both sides of the new seal with petroleum jelly before installing. I cleaned the original bolts with a wire brush on a grinder and applied Permatex 59235 high temperature thread sealant to all bolts. I'm pretty sure stainless steel bolts are a bad idea; Because stainless silver is weaker, they are more likely to crack over time due to engine block heat. Works great so far!
