    Has you replaced the thermostats? It, happen to me too, it was leaking trought the reservoir but was hard to find since the leak was coming only while i was driving, detroit replace the thermostats and told me than the problem was that the gasket that goes around the thermostat was too old and not was sealing right, anyway it works for me.
