How did you determine this to be the issue - is is a visible leak dripping off the engine?

I've noticed my coolant levels going down about 1" in the reservoir every couple months it seems. I never see coolant on the ground or undertray though.

 

I found coolant all over the bottom of the car; spread over front sway bar and on the power steering rack. Level has been going down and I smell coolant inside the car with the heat on.

Haven't found a leak yet!!!!!!!!!

 

Doesn't look like I have a leak at the water outlet or water pump. The car has never overheated.

 

Could be your heater core, antifreeze will come out of your AC drain. Often you will see unusual window fogging issues as well.

 

Where is the drain??

 

No leaks from the heater core connections at the firewall.

 

a heater core leak would normally cause very foggy windows that don't clean....they just smear from the coolant. Also, you can notice fluid under the floor mats sometimes. You would see coolant under the car after car is warm and it would be around where the engine/trans meet up at the bell housings most likely.

 

I haven't noticed my windshield being unusually foggy, my car doesn't overheat, and the heat is hot.

 

Had the car running on stands and still could not find the leak.
