If you noticed a funny smell when turning on the heat then your heater core is likely has a slow leak.........It is a 6 hour job shop rate and the heater core is around $200 depending on where you buy it. Let me know if you have questions, thanks.
You could have a small external leak but you would likely see a little coolant dripping off the engine if that was the case........It could also be intake or headgasket problems but vehicle would be overheating and you woudlnt smell anything inside with heat on..........I'd feel comfortable spending the $ on a heatercore if it were me. Let me know if you have questions, thanks.
