Re: Lincoln Cooling Fan

Pull the thermostat. out leave it out
Put the lower hose back on and stick a garden hose in the fill of radiator.
Take off the top fill hose and leave over top of radiator. (tie it off so does not fall into mechanicals)

Fire it up let it run and see how much flow your actually getting thru the system. it should hardly get up to operating temp with the constant flow of cold water in system.

That will tell you a lot. you can even measure gallons per minute in a five gallon bucket.
