Exclamation HELP - Coolant Leak in 06 Cobalt LT 2.2L

I am trying to figure out what is leaking in my 2006 Chevy Cobalt LT Coupe, 2.2 liter ecotech. I have taken some pictures of a bolt on an assembly that is leaking. I know nothing about engines, and I am in hopes of someone on here knowing what that bolt is in the picture. Please feel free to email me as well, if you have any mechanical pictures, as I need to get this fixed before it escalates. I only have to put about a cup on coolant in my vehicle once a month, so the leak must be little. Any input is appreciated. Thanks - Sean

The water that is coming down the firewall insulation appears to be from your AC drain. Have you been running your AC or your windshield defroster? If so that may just be the moisture from the evaporator -- normal. You can just see the square plastic drain tube that comes through the firewall in your photo -- second photo, just above the bolt.

What is not normal is if you are having to add water regularly. Then it could turn out to be your heater core.

If that is the case take it to the dealer if you're still under warranty...

Oh ok, then I wonder where I am leaking coolant, lol. Once a month my low coolant comes on, and I have to top off the coolant level on the reservoir. I have no signs of a blown water pump besides I smell coolant outside of the vehicle. I hear no whining from the engine, puddles of coolant, or anything else...Dealer said it could be a water pump at $750.00/installed. I am trying to avoid that at all costs, considering my cobalt does have 80k miles and off all warranty. Thanks!

Hate to say it but a water pump can leak in a way that it leaves no puddle. Most water pumps have a "weep" hole to warn of water in the bearings...but I don't know how the Ecotecs pump is made.

Check the fluid coming out of your drain...should be clear water -- if it smells of antifreeze then it could be your heater core leaking.
