Bleed hole in tstat?

[HoonLo]

I recently bought a new tstat. 180 (jet) as I live in canada I could not go to autozone and get the 4127 or 8 then I watched the video for the install and was struck by something. In the video he talks about a bleed hole or something but on the jet I see no such thing. Has anyone else noticed this and or will this thing work well??

This has been discussed a lot in the past few days, I even posted pictures.
That's why we've been saying the autozone 4128 is the best choice, it has a large opening and a relief pressure valve in case of coolant system failure.
I have the jet too, but it's gonna end up in the trash now that I've learned about the 4128, which I bought a few days ago and will put in soon.

Left is 4128, right is jet (which looks the same as the napa 191)

Hmm I will have to check to see if a can procure a 4128 myself, It is a motorad right?
