I have a 2016 Toyota corolla. How does one bleed the cooling system?

Won't some of the coolent spew out whrh the cap off?
No, there won't be any pressure buildup with the cap off. (A little might spit out as the pump pushes coolant through but not enough to be a problem.)
Also won't the funnel potentially melt from being on the hot radiator?
No.

Only if you just drove it to operating temperature and you didn't give it a chance to cool down. The water pump pressurizes the coolant when it's at operating temperature, regulated by the thermostat. Stereotypically in movies, when your car overheats, there is a spring-loaded valve as part of the radiator cap that releases, instantly turning the coolant to steam. Never, ever take the radiator cap off of a hot engine. The coolant could scald you. When you release the 15 PSI of pressure (the boiling point of water raises slightly when the coolant is under pressure, which makes the engine more efficient), you instantly turn water to steam if you literally just ran it to operating temperature.
Start work on the engine's cooling system after an hour or two to let the coolant cool down.
Did anyone ever try exchanging coolant in the radiator by partially opening the drain valve and slowly adding coolant at the same time using the funnel? You'll probably end up wasting some coolant in the process but hopefully won't need to bleed the air afterwards. I think this process should work if you attach "coolant funnel" and keep it full to prevent air getting in. I never tried this method before and just wondering....
this makes no sense. just drain out all the old stuff.
