Antifreeze smell help. Lot's of new parts
Well, I drive a ton, never overheats, temp runs good, just below 1/2 actually. I keep smelling it so I replaced: new radiator, both main hoses, and the auxiliary water pump and I still smell antifreeze. I don't see any leaks on short or long drives. Nothing in the oil that I can see, I just changed it yesterday and it doesn't seem to be losing any water. Bottle is still full, when you take the cap off rad is down to the top of the fins, but I know the bottle fills it back up when it circulates, right? I don't see any on the ground or in the oil, any other thoughts?? I smell it pretty strong every time I stop.
It's a 5.7 that just hit 101k.

Sounds like you have done a pretty in depth parts replacement to try to cure this issue. Having gone that far, I would have also done the thermostat since the system was drained.
You may have a loose bolt on the snout that hold it to the side of the water pump. Could also be a seeping/weeping heater hose or seal on the water pump. Coolant leaks have a habit of dripping onto the hot engine evaporating so we don't see them, and just smell them.
Might be productive to pressurize the system with a coolant pressure tester and look for leaks with a cool engine.
You might be able to see the drips then.

id check under your carpet, or turn your ac on full blast and let the car get to operating temp and smell the air coming out of the vents if it smells like coolant more than likely you have a pinhole leak in your heater core, if not check your main water pump weap hole.

You can get the fan off the pump by using a 10 inch crescent wrench opened to the max.
I was able to fashion a tool to hold the pump pulley in place, or you could use one of those belt type wrenches to hold it stationary.
It it on there kind of tight, but a good twist will break it free.
Mike:
If you are doing the pump, do the T stat also.
