My wife has a 2003 grand am and it recently got a syrup like smell in it . i did a little research and from what i read people say its usually the heater core going. they also say that coolant will leak on the carpet but i have yet to notice any coolant on the floor of the car. anyone agree with the heater core or should I also look at other things. also does anyone have a DIY on swapping out a heater core on a 2003 grand am cause i was quoted $586 to replace it
