i have a 07 civic ex my car trys to over heat and i dont no what to do antifreeze is full will it be my Thermostat please help me

 

Did you check in the radiator or just in the white plastic tank? With the engine cold, remove the radiator cap and make sure it is full.

Simply replacing the thermostat pre-emptively is typically the first thing to try with mysterious overheating. They do go bad and they are not very expensive.

What are the circumstances leading to overheating? For example if it overheats only at low speed or sitting still it could be because the fan doesn't work.
