Replaced my radiator after it took a sh*t on me, drove the car to work this morning, on the way home about an hour ago there was instantaneously a noise after starting the car that got louder the more I turned. This sound was consistent the whole way home, then went to check it out with my buddy and it disappeared for 10 seconds after turning the car on. It started up again. Could replacing the fluid fix this or is it something worse? I don't know if the new radiator could have anything to do with it, any help is appreciated as this is my only means of transportation. Thanks.
