So I chnaged the water pump and after that i changed the thermostat. The car was overheating, so i put the thermostat in boiling water and it opened up after a long time. So I tested the old Nissan Tstat i took out originially and it opened up right away. So I used the old t stat. And the car is still overheating. The coolant is boiling as I can hear. What do I do?

You might have a clogged radiator.Look down inside the radiator,if the cores have crap around the openings it might be clogged up. Try buying a new t stat.

You could have air in the system.

Is there a purge valve on the cooling system?

It's bubbling and the mechanic says its boiling. Could it ju8st be air. The temp guage rerads normal.

UPDATE.

I found out that I had to bleed the coolant. No more bubbles. I have one question though, the upper hose is hot but the lower hose is not. Shouldn't it be hot too? keep in mind that my t stat is still the old one because the new one was broken. Please help. thanks in advance.

When you checked the bottom hose was your car warmed up?

Yes, warmed up.

Sounds like a clogged radiator to me. If it was the thermostat your top hose would be cold.
