Head gasket, heater hose, heater core.
If it's the heater core, (unlikely at only 6 years old), fluid will be dripping from a small rubber tube on the firewall if the car has air conditioning, and onto the right front floor on cars without air conditioning.
Head gasket leaks should be visible after crawling underneath. Slow leaks will show up as a white stain running down from where the cylinder head meets the engine block.
