Ford Focus SVT coolant leak at thermostat housing

(5 reports)
Leaking aluminum plug in thermostat. Suspect failed O-ring but waiting for repair. -
At first the dealer misdiagnoses the small coolant leak and made unnecessary repairs. Then the leak was found in a crack on the thermostat housing (which is plastic by the way). That was at 70,000 miles. Now at 110,000 miles, it has a tiny crack again and I am not going to spend $400 to replace it. I put in a chemical leak sealer. -
i replaced the thermostat and the o ring must be my housing bcs i took it to a shop and they checked all my radiator hoses -
