For one, you probably have a leak, and also you probably have a clogged heater core.
You have a leaking heater core. You might smell antifreeze if you turn on the defroster.
If you are smelling the sweet but unpleasant aroma of antifreeze, your vehicle is leaking it somewhere. A lot of the time the culprit is the water pump. They have a weep hole and when the bearing starts to fail it will begging leaking from this hole. I would start by getting myself a flashlight and start scanning your engine's water hoses for a leak. Check the mail hoses going to/from the radiator as well as the heater hoses leading to the firewall. Do you smell the antifreeze odor INSIDE the car? If so, it could be your heater core that's failing.
I had one do this and I had to change the brake calipers. Problem was gone.
could be oil leaking from the engine.could be oil around the engine while the mechanic was filling the engine with oil. could be a plastic cable burning on the hot engine.could also be the smell of a cleaning product you use on your engine.might be an animal trapped inside your hood. could be antifreeze on your engine.you can also pop the hood and see :)
Freon is odorless; you cannot smell it.
your vehicle may smell like antifreeze while driving because it is overheating
if you can smell antifreeze you need to replace the heater core in the vehicle
A small amount of antifreeze smell may be emitted from the radiator overflow. However if you smell antifreeze you need to make sure there isn't a leak. It may be something simple if you catch it early.
Maple syrup.
Flush your radiator and get that orange antifreeze GUNK outta there! I flushed mine...my mechanic added green antifreeze and all is well....that orange stuff eats and destroys....

The smell of antifreeze is very strong and distinct, it does not take much of a leak to smell it. The radiator could still be full and have a small leak. I would check for antifreeze dripping onto the exhaust or on the engine block because when it is hot the smell is much more noticeable from the fumes.

You have a coolant leak.
