Yes I expect it when it's cold and have seen it but when it's 67f out and foggy no and no other car with a v6 has any exhaust out put of cold vapor . I was just wondering if anyone heard of this yet ? I don't have any head gasket leaks and the 11 sv has 22,000 miles on it and clean carfax with oil changes and regular services at the stealership.

 

It's just condinsation! I've seen it here even in 70+ degree weather. Part of your catalytic converters job is to turn unburnt hydrocarbons into carbon dioxide and water, which can cause the same look as vapor in cold weather!

 

It doesn't make since when my car with 22,000 miles in a drive the I seems to smoke and all the others including new ones don't ? It's quite embarrassing .

 

Did I mention I have an associates degree in automotive too ! Yeah I am educated . Thanks

 

What are you trying to say here? Just kidding, seriously its only condensation, all cars do it. Just today I was behind a Toyota and it was flowing water out the exhaust. Btw, I'm in California and the temperature today was 55 degrees.

 

It makes me weary then I smell a small hint of antifreeze and I know what that smells like. And I checked out the block myself with no leaks but under the reservoir cap there is slight buildup .

 

koreanthunda, I have a 2010 SV with 63,350 miles on it. I also smelled antifreeze but only after driving on the highway. I checked and didn't find any leaks either. I recently drove 1500 miles when I moved from KS to CA.


On Saturday I took my car to the dealership here to get my oil changed and I mentioned the antifreeze smell to the technician. They checked it out and didn't find anything wrong and my fluid levels were good as well.


I personally am going to get more information such as, under what circumstances the smell is present so I can give the dealership more info to go on if I need to take it further.


In the meantime they've logged it in their system as a complaint, and I would recommend you do the same with your dealer also.

 

If it does, have you've done a pressure test to see if there is a coolant leak?! Btw, I'm not trying to down play your knowledge on cars, as I've got one too and turned wrenches for 10+ years! Just throwing suggestions out there!! I apologize if I did

 

No but I don't have a tester . I am going to have the stealership check this out when I have the oil changed next week for free . I just got the car at19,000 miles 30 days ago .

 

Man, free oil changes, I had lifetime free oil changes at my dealer in KS. Not here in CA unfortunately, the only good thing is that they only cost $40. The other negative is that mid grade gas is almost $1.00 more than what I paid for premium in KS. Good luck with the pressure test.
