This is not for a Honda but it's a pretty general question, have a grand prix and it's overheating bad. I notice that the radiator hose going to the motor (on the right side) has a shit load of air pressure In it and no coolant like pressure building up.

So not coolant is goin from the right side of the radiator like somethig is clogging it or blocking it.

Could it be the radiator or thermostat or what?

Any help is appreciated and rep thanks
