Default Eating coolant!!!

So I recently replaced my radiator and thermostat on my 95 Civic Dx and noted that it sucks through coolant. There are no signs of leakage anywhere. It goes through about a coolant tank (that white tank on the radiator) in about a month of city driving. Any ideas?

If you just chaged the radiator did you make sure to run the car with the heat on full? Coolant has to flow into the cabin where the heater core is too. I ran mine for about 15-20 minutes with the heat on high, so that the fans turned on at least 3-5 times.

did you bleed the system on a flat surface? Did you bleed the system with the heat on? How long did you let the car run?

10 minutes is not enough time to even get the car warmed up and go through maybe 1 fan cycle.

I usually let it idle for about 2-30 minutes when I'm bleeding the coolant.
