Hello, So today I replaced my Buick’s water pump since it was leaking. Everything went smooth refilled with coolant and started engine. After 5-10 mins of car running the new pump started to leaking from the same place as before with the old pump . I used Permatex gasket maker on gasket both sides. I also made sure all bolts were tight. Could something possibly went wrong when installing ?? Could the new pump possibly be defective? I’m going to exchange it tomorrow for another one and do the job all over again . I really want to get it right this time .any advice helps . Thanks .
