Have a coolant leak that is not visible and not showing on ground. Have checked oil not seeing any coolant in oil or smelling in exhaust. Coolant was topped of three days ago was low enough to cause heater problems this morning.

Assuming it is a 3.4, as you gave us no egine size, common issue is the lower intake manifold
