Today .. i installed a new water pump ...
put everything back together... added new coolant while the car is off.
Turned the engine on .. every thing seemed good.. no more leaking !
i kept adding coolant to the radiator... then filled the coolant tank to "full"....
then i noticed steam coming out from the radiator cap and it felt hot!
i also touched the upper radiator hose.. and it felt hot too !
actually .. i noticed smoke when i was reving the car !
but did not know where it was coming from exactly coz it was dark!

anyone know what the problem might be?!!! or is that normal?!
