Re: 1994 bronco E.B. 5.0 fan clutch
Fan clutch? Usually it is the part mounted between the engine and the fan, when the engine is cold it lets the fan spin slowly, it locks up with heat to spin the fan faster and help draw air through the radiator and keep the truck cool. It should not effect the coolant unless the truck is overheating.
Best way to figure out a leak is to get a pressure tester. You hook it up to your truck cold, usually to where the radiator cap goes, block up any out sorces such as the overflow,and pressurize the system. This forces coolant out of leak points, if the system holds pressure, the cap may be suspect. Being that you are on Long Island I may be able to tell you where to get your hands on one of these. Where do you live?
