damnit. well the car started overheating again. took a while for to start. drove for about 500 miles everything is good. so i am driving home then the temp gauge starts rising and stops at about 5/8 of the way. i previously changed out the thermostat, new cap and got the radiator cleaned out. so now i am guessing it could be the water pump or there might be something wrong with the headgasket. is there a way to test the water pump? any help is appreciated.
