Thanks for the replies. The fans were working last month, i remember hearing them come on. Haven't heard them since. A few days ago, let the car run in my garage, it heated up beyond 100 and the fans did not come on. The next morning i noticed a good amount of coolant on the ground, it apears the coolant came out of the overflow tube. The coolant level seems to be fine though, same a it was. The thermastat, water pump, coolant hoses and OVP relay were replaced in the last month.

The fan between the engine and radiator is working. Could this be the Auxiliary Fan Relay? does anyone know where this is located on the 190e 2.6?
