I recently was in a front end accident. There doesn’t seem to be any catastrophic damage to the front end of my car, other than minor scratches. Today I noticed an antifreeze smell when operating the car with the air conditioning on. I looked under the hood, the resevoir is full, neither my boyfriend or I saw any visible tube cracking, and there are no drips on our driveway, as if it is leaking. Also, the coolent light has not come on at all. Any ideas out there as to what may be causing this smell?
Check the pressure cap. Have it pressure tested.
