my car started overheating more than a month now, first time it happened so quickly and i didnt have time to switch it off so the radiator and water tank blew up. so we changed radiator, water tank and maybe thermostat..
after 1 or 2weeks it happened again, this time the guy who repaired assumed after checking it on computer that electric fan is not working so we changed the fan
after 4 or 5 days overheating again went to the same guy and this time he assumed it was the water pump and some connection to it, so we changed them.
after 4 days same problem, so i went to another guy he assumed that the replaced fan may not be working properly cause they are facing similar problems with the (non original fans) so we replaced it with an assumed better one
same day problem happened again, so now the reply is the 2nd replaced fan is not working..
so i am confused is it the fan itself or there is a certain electrical connection failure that is making this problem?
can someone advise?

You should have a chemical test done to check for a blown head gasket which may have happened in the previous overheat.
