Ever since I swap B16a2 in my EG I had a **** load of problem. First this **** didn't start that been fix. Then this **** happen dam motor overheats as soon I as start the car and let it run for a little. It seem like coolant doesn't pump around, upper radiator hose is hot as hell and the lower hose and radiator stay cold. I bought a new thermostat and **** still the same. Anyone know how to fix this problem?

 

If the lower hose isn't hot, then either the coolant passages are blocked or your thermo is bad and not opening the return valve.

 

it's possible that the water pump bearings are bad

 

sounds like an airlock to me. Jack the front end up and fill the radiator up and squeeze all the hoses like a pump until no more air comes out- then run the motor.
