How do I know if water pump or a gasket is bad on 2003 Tahoe?
if the pump makes a noise its bad. if the water comes from the pump its bad, you must replace the gasket if its the gasket , so remove the pump and if u have it in your hand you will see if its the pump thats leaking.
No notices are coming from the pump. Thank you for your reply
Of all the water pumps that have gone bad on me only a small few made nosie. There is a weep hole in the pump that leaks water when they begin to go. Look for that.
