fitted a new plug to my thermostat housing which has stopped the trickle down the bellhousing but i seem to have always had a slight drip after running the car which comes from the black plastic strip that is directly under the radiator....no pipes seem to be leaking etc though is this likely to be condesation? although it smells like weak coolant (the mix in my car is 70% coolant i would say after doing the plug i topped up with a strong mix) also i dont think its a leak as surely it would be hot not stone cold especially notice this after a journey when engine is hot.... seems odd that it stops after about a pipette worth of fluid everytime and sometimes notice a small wet patch on drive about size of a £2 coin

is it possible it could be condensation from the aircon rad

i cant work out what its from i never had a large patch of coolant on drive either only a small damp mark

2004 st170 in mint condition i just cant imagine the rad is gone already

 

Could be washer fluid from the pipe which feeds the headlamp washers....
