Alright well when im driving, the temp in the car is in the middle but when i come to a stop the heat rises. i checked the engine and the radiator fan is not turning on..is this the problem for over heating?? i put anti freeze in and turned the car on and the fluid got sucked down. but no radiator fan?? well i also recently got it smogged and the timing was off, it was at 6 when i guess its supposed to be at 16. could this also be the reason the car is overheating? thanks also how can i fix this problem? thanks once again
