Hey guys, i already read a couple of other forums with regards to the issue but they always ended being something else, with that being said, i have a 2001 mustang gt with a slight coolant leak that i pin pointed to a little black plug/grommet on the passenger side firewall about 6-8 inches ontop of the left(facing car) header pipe. i dont know what causes it to begiin leaking considering the fact that i RARELY ever put my AC on and when i did i started smelling a syrup smell from my AC. i m pretty sure its not my heater core since it just started leaking and i have 64k miles on the car. if someone can tell me if they experienced the same problem or know how to fix it i d greatly appreciate it. I thank and appreciate any help in advance.
