I noticed the same leak in my RS yesterday. I am ordering a housing and thermostat tomorrow. Priced around today. Bought a rubber ring thing off Ford yesterday and was going to change it today but was told I'd be better of chnaging the lot, the housing, thermostat the the Yellow cap of the coolent bottle.
Are they the same parts on both cars.
