1994 bronco E.B. 5.0 fan clutch

How can you tell if your fan clutch is going bad.My bronco loses anti-freeze,i put in a new radiator and water pump.When i go for a ride and then park it,i get a little puddle of anti freeze were the radiator is.The puddle is only 4" long,and it never over heats.I am thinking the fan clutch is going,because it don't leak when i driving only when i shut it off - then it will leak.Has anyone had this problem,any help or advise on this would be great.All the hoses are new too.thanks.....grasshopper

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?

It's not the clutch - it's the water pump seal. If you get to the right angle, you can see the vent hole on top of the water pump snout inside the pulley, and you'll see a trail of coolant residue.

Change the pump.
