My wife drives a 2000 Excursion with a little over 80k miles and recently I have smelled the sweet smell of anti-freeze just after it's started. Seems like I smell it more if it has sat and cooled for 30 minutes or so and when she restarts it the smell is pretty strong. It's not so noticeable at the exhaust pipe after it has been running for a short period. So I'm curious if any of you have gone through this and is the headgasket being blown the only possible cause? I checked the anti-freeze level the other day in the radiator and appeared to be full. So if it's burning anti-freeze it's not burning much. How much is this likely going to cost? Thanks much for the info in advance.
