What's good Everyone? So my civic has need over heating, so I changed the thermostat. This was 4 months ago. Car over heated. There was no circulation. I changed it again. It's been fine for 3 days. Now it's doing it again. It blows the fluid out the reservoir. Not sure we're else to check. Please help if possible. Thank you in advance.

 

No coolant circulation could point to a bad water pump, but also consider a blown head gasket
