If its from a leaky frost plug or elsewhere it's going to corrode the surface of the flywheel and clutch/ pressure plate together over and over again.If you want the quick cheap way out put some "Stop Leak" additive in the radiator, pry the pressure plate back again and then slip the clutch so as to burn the corrosion off the surfaces.The best solution however,is to take it apart and fix the leak, resurface the flywheel and put in a new clutch/pressure plate. Good Luck/Mark
