DavidKDenver Posted December 27, 2006 Share Posted December 27, 2006 Lately, I seem to be getting a faint, musty odor of coolant while using the heater - and right now, that's just about all the time. Could I have a leak in a heater core? I don't see any mist from the vents which occurred in another vehicle many years ago. Otherwise, what else could cause this?
