Hi everyone - I bought a 2004 1.2 Nissan Micra that had be sitting for around 5 years. I changed all the fluids and I changed the coolant and thermostat as well as a precaution. However even since I have changed the thermostat it seems to be leaking from the thermostat housing. I have tried two different thermostats and none of them seem to fit snugly (which is what I think the issue is. I have put sealant around the housing as well to try and stop the issue but still no luck. Does anyone know the best place to get a thermostat? Or why it may still be leaking? I'm at a loss, or any tips on how to do the thermostat as maybe I have done something wrong?
