So I have replaced the water pump, thermostat, timing belt, and idler bearing on my 3.3 liter V6. I am still loosing coolant and do not know where it is going. The oil looks good and heat and air is working. Could someone please help me find what's happening. I am at the end of my rope on what it could be. I cannot see any leakage what so ever and just can't figure out where it is going...

Head gasket issue? Would a leak-down compression test be useful here? Not sure what is definitive for a possible micro head gasket leak.

What amount are you losing ? I know these are stupid redundant questions
Head
1 most likely smell sweet exhaust an see white exhaust if burning
2 see bubbles in your rad
3 leak down test
Heater
1 dampness carpet wet floorboard
2 smell sweetness in car
3 leak dye
Leak
1 You've checked the rad, every every hose connection an mating surface for staining
2 engine is clean enough so you'd see evidence of staining
3 park same spot no leakage I had trouble once cheap n easy way was to just stick cardboard under car and parked on top of it
4 leak dye

Coolant is either leaking or burning, no other choices.

Leak could be internal, is your oil level or ATF level increasing correspondingly?

Was there a leak you found and then did those repairs? Or was that your "guess' ?

Remember: leak could be in heater under the dash too, don't forget that.
