Thermostat gasket

[djheath]

Hi,

I have just bought a 1999 406 petrol 1.8. I have notcied the thermostat housing is leaking coolant between the engine and the housing. Is there a gasket that should be used to seal it, or can I fix the leak by removing it and using some sealant on the join?

If so, what sealant should I use?

thanks,

David.
