Is this not the radiator/antifreeze drain plug? Thanks might replace orange with yellow.

why on earth would you crack open a sealed system for no reason?

To put in the yellow coolant. 200k vs 100k life. Working on the truck is always fun. This truck is pretty easy to tinker with.

If you read the fine print if you replace the orange with the yellow, it will still be only 100k, not 200k.

Yep. Wait until 100K mi. By then something newer and better will show up. .....for the next 100K mi.

I got lost in the thread. So, can Zerex G05 be used in a 2020?

I have seen some of the older coolant caps separate like you are describing but that is usually due to high heat and ppastic not getting along.

DY = Yellow-colored engine coolant approved to Ford specification WSS-M97B57-A1 or WSS-M97B57-A2 (Motorcraft® Yellow Antifreeze/Coolant) according to https://www.fcsdchemicalsandlubricants.com/quickref/coolantsEN.pdf.
G05 says it meets WSS-M97B51-A1 spec, according to the PI sheet from https://www.valvoline.com/our-products/antifreeze-products/g-05-antifreeze-coolant . That's an old spec, so it appears to be a no. (https://parts.ford.com/content/dam/ford-parts/resources/motorcraftpdf/Coolants_Brochure.pdf)

Besides, the cost is about the same, so why bother?

Yes, you need this device. There is no direct way to get coolant back into the system. Just filling the reservoir won't work.

The service manual has a procedure for: Filling and Bleeding without a Vacuum Cooling System Filler.

Yeah.... About that procedure...... Its a great way to waist an entire day if you have nothing else better to do. The unfortunate truth as I have done that before!!
