Water pump most likely. Ive had 2-3 on previous vehicles where I could only smell the sweet syrup smell but never saw any puddles. It usually leaks from the weep hole at the back like stated above.

on this trucks the water pump seals go out and the house coupler at the firewall cracks as well. my bet is the waterpump to engine seals have cracked

Lol.. easy! HIGHLY doubt its internal if its not been ran hot. Like was said its probably heater hose connections,water pump,radiator, but dont rule out freeze plugs or heater core..get you a pressure tester,mirror, and a good flashlight and park it on some clean concrete! Look over it SLOWLY
