Coolant reservoir overflowing

What is your question?

My 2007 Nissan Murano keeps overheating even after replacing the thermostat it keeps backing up into the reservoir and overflowing like the thermostat is stuck what is causing this

What makes this problem better or worse?

It's worse when the engine is hot

How long has your 2007 Nissan Murano had this problem?

I had to replace the power steering high pressure hose and noticed two coolant hoses underneath the vehicle that needed replaced due to the leakage ever since I had to drain and refill the the coolant I've been overheating
