It's all in that thread, some have just replaced the o rings because the plastic part is probably fine. There's another common leak point discussed, too. Right at the degas bottle. You might want to check yours.

I just went through this on mine. It's a common failure problem for some reason.

This is what you need. https://amzn.to/3tKvvlW

I replaced that and it stopped mine from leaking.

I replaced the O ring on each side of the y. 10$ fix. Drain a gallon or so of coolant before you do the fix.

I bought my O rings from theoringstore.com. 4mmx31mm and 4mmx37mm Buna N 70 Duro O-rings and some synthetic lube. I can't remember the cost but it was real cheap.
