fans are pretty cheap off of a dihatsu charade at the wreckers. and then get the little thermos that keep em running at certain temps and when you shut off your engine they keep running to cool engine to lower chances of water boil in the jacket.
as for pumps drop into you local auto parts store i think that company craig Daveys is one they make thermo fans and oil radiators and elec water pumps and stuff. they used to sell em at marlows/ rocca bros. but now it's super cheap i don't know real assholes in there now. don't like shopping there
