i just changed my thermostat, thermostat housing, upper radiator hose, and coolant. i turned the motor on to let it idle and circulate the coolant, then filled the radiator back up. after the car runs for 5+ minutes or so, i can hear a dripping that sounds like it is coming from inside the engine. it doesn't sound normal! anybody know what it is?!

 

Huh?!

How do you hear dripping inside a motor thats running??
