I would like to replace the thermostat with a new Nissan one. Do I need to buy a sealant like RTV or will the seal that comes with the new thermostat is good enough to stop any coolant leaks? Thanks.
i'm no expert but i got my k11 thermostat with a few difrent gaskets
and some members recomend using the gasket with a thin line of gasket sealant-i would too
