hi Guys,

have removed the thermostat housing unit off my 4x4 sapphire cossie to replaced a deteriorated water hose and noticed that i also need to replace the circular rubber seal found in a recess on the face of the thermostat housing unit where it meets the cylinder head. help is greatly appreciated in sourcing this seal .

BTW is it right to have a rubber seal there or should there be a paper gasket over the whole face like there is on the thermostat housing cap?

many thanks for your valuable help
