Water in tailpipes!

It doesn't smell like coolant and it doesn't smoke either but it does have this peculiar smell about it. And if it wasn't so friggin hot outside (I was sweating just standing next to the car while it was idling) I would just think it was condensation. But the darn thing gets worse every time I fire it up. Today I could hear a "gurgling" sound coming out of the passenger-side tailpipe. One time I saw a steady stream coming out of the connection right after cat. So my question is...

Is this normal? :dunce:

Are you losing coolant? do you usually just drive short distances? try buying gas elsewhere next time.

I drive it in and out of the garage and that's about it. Don't think I'm losing coolant.

well, it is normal for water tome come out of your tailpipes, but only a certain amount.  remember, if combustion was a perfect process, the only by products are CO2 and water, so nomatter what the car, there will always be a lil water.  on a real humid day there may be more than normal, but not much more.  ive literally had steam come out my tailpipes like a plumb.  but if theres constantly water coming out in streams all the time, there could be something wrong.  i agree with tbirdscott up there, try a different gas station, see if it changes.

I agree with everyone else, with one addition based on your comment, "I drive it in and out of the garage and that's about it."  You could get gas somewhere else, but first drive it 10-15 miles to get it good and warmed up. Then see if there is any water coming out of the tailpipes. My guess is there won't be. It sounds to me like it's just normal condensation in the exhaust which will evaporate once your car is up to its regular operating temperature.

Ether947 mine did that to, even after a long drive and I came back I would still have two vapor puddles under the tale pipes it drove me crazy. No coolant loss and I even did a chemical test over the radiator it came up negative. But I always got my gas at the same Exxon up the block which is bran-new. Anyway what’s funny is once I did my cat back exhaust straight pipes, no s, I don’t see it I wonder if  I just had to much water in the s. I’m still confused.

Mine did this. If you do a lot of idling, it can happen.  What i did was drill a couple of tiny holes in the lers, and it cured my problem.  Mine was so bad that if I would slow down quickly, water would slosh back into my y pipe and hit the cat, causing it to smoke like crazy..... or freeze the cat up  completely, like it did this last winter.

I don't have any lers. And yeah I do a lot of idling to run my "battery of tests"! :D If this is normal then I'll just have to deal with it for the time being. I just wish it didn't break up my exhaust note. :)

find the low point in your system and drill a 1/16" hole for the moisture to drain.

Ditto on the drain hole.  Most car manufactrers put a small hole in their lers nowadays for condensation drainage.  The Mustang had drain holes on the stock lers.
