2010 V6 Coolant Leak
Just noticed that my Camaro has started leaking (what I believe to be) coolant under the passenger side of the engine. There was a fairly large wet spot in the garage yesterday and when I looked under the vehicle a large section of the frame was wet.
The fluid appears to have a red/orange color to it but when I touched it with a tissue it appeared clear. I put it up on the ramps and crawled underneath to try and find the source but it seems to dissappear somewhere between the block and the alternator. I took a picture of the underside to try and show the area it's leaking from. Hesitant to take it to the dealership as I don't think I'm covered under any warranty. (56k miles and was purchased secondhand although it was from a dealership and was chevy certified preowned) I checked the coolant level in the overflow reservoir and it seemed low but was still one notch above the minimum line. Is there a place to check the coolant level for the main system? (i.e. not just the overflow reservoir?) Any advice/tips are appreciated as I'm stumped. The red circle is the highest wet point on the block I can see. Can't really see any wetness from above. |

When the engine is cold, remove the radiator cap and check the level in there.
If you have a large puddle, it's time for a visit to a shop. |

Well I checked the coolant level in the radiator after letting it sit for a day and it was literally as full as can be. I topped up the overflow reservoir since it seemed fairly low but I'm not sure if it's changed in the last few days as the level measuring stick doesn't seem all that accurate but I put cardboard covered in paper towels under the car and there was only like a 1-2inch diameter wet spot on them so only a few drops over the last few days. Seems like an awfully slow leak that may or may not be exaggerated when the vehicle is running.

My 2011 v6 did the same thing. They said it was the thermostat housing

If you have a trusted shop or mechanic, i'd ask for an opinion. That's not many miles, i would be concerned about any fluid leaking at 50k.
