08 L3 with 135k. I?ve had the sweet smell of antifreeze for a long time now. Thought it may have been from fluid that spilled while replacing the thermostat and tconnector but that was close to 2 years now.

No signs of leaking at all and don?t have to top off fluids maybe once a year. Seems to be coming from front passenger side (nearest the radiator).

Truck runs great. Drove it from CA to NC last spring with no issues.

I'd be looking around the radiator and thermostat housing. It doesn't take much to get a smell.

Or do the coolant pressure test to find any leak.

Bet its the Radiator. Would be the third one I sold in the last two weeks and all began leaking on passenger side.

Check water pump for slow seeping coolant.
