I've done several searches and can't find anything related to my problem. Just yesterday went I parked the car after driving it for an hour on the interstate, steam coming from underneath the car. All gauges were working, rasied the hood and the coolant was full, so didn't worry too much. When I got home (another hour drive) the same thing happened. I got on the ground and saw something dripping and hitting the exhaust. I caught the liquid in my hand and realized it was "cool" water. It left no residue on my fingers, no odor, it's water for sure. Only logical assumption is it's condensation from the a/c dripping down. It's at the back of the firewall, in front of the transmission.

Anyone have any insight into this? I'm hoping it's a drain line that worked loose or something. Weather wise, it was 101 yesterday, but it's been that before without the problem. Did it again today as well.

Thanks for any help.

 

i have a c230 coupe and the same thing hapends to me when i use my A/C

 

thanks for the input! I'm taking it by the stealership tomorrow for a check. Glad to know I'm not the only one.

 

its normal , evaporator drain hoses !!!

 

Took it to the dealership. Evaporator drain hoses weren't designed to empty onto the exhaust. Problem was some dirt in the drain hole. The guys called me back in the shop and showed me where they were and how to fix it. A screw driver stuck up in the hole broke the trash loose and now my a/c drips normally. The plugged up drain was causes the water to "divert" since it couldn't flow straight down.
