I need some help. I have an 04 civic ex, and I'm losing coolant somewhere. There is no leak and its not coming out of the exhaust, but every 2 to 3 days I have to add about a 8th to a quarter jug of coolant in. I've heard a few theories and I just would like some clarifications so I know what I'm getting into.

 

have you checked your heater cooler. located in the fwd ctr consol. normally you will smell a bit of anti freeze in the cabin of the car. or the floor carpet may be damp.
