Welcome to this forum! I've moved your thread into the stock 2002-2005 section. Get a cooling system pressure tester from Autozone's tool loaning program to see where the leak is.

Same happened to me. Got progressively worse over time and I ended up with a ceased engine. Are the two related? Maybe.

Check your oil for anti-freeze...maybe even have it analyzed. Your head gasket may be the culprit.
