I took it to ATI tonight cause my friend was just checking the brakes for his class and one of the teachers said it could be the radiator cap. also, there's an electric fan on the radiator and it doesn't look like it's turning on. the mechanical fan is, though. another thing: the reservoir has a vent hole in the top and the teacher at ATI said it might not supposed to be like that. I need a new reservoir anyway cause that one is a little cracked. thanks everyone for your help, hope I can get this thing cool.
