Silverslug04

My 04 GT os burning coolant, i cant find where its coming from. I replaces the water pump, valve cover gaskets, and spark plug tube seals. Its not doing it at a cyclic rate but its disappearing. And no its not in the oil, ive changed it twice and no signs of coolant. Could it be the coolant im running in it? Im using greek cap. Dudes at o'reillys said it was good to use. Any ideas?
