2019 V3. 33k miles. Want to check SC cooling fluid level but can’t locate expansion tank. Videos show me where the bleeder valve is but I don’t think that’s what I’m looking for. Thanks in advance.

yep, thats pretty much all we got, no reservoir
couple places sell an adapter a lot cheaper than gm
~20$ from dedicated LT4 SC Coolant Filler Adapter Tool
needs to be topped off, ran, topped off, ran about 5 times before its good
