Hi and thank you for your question.Yes, it needs to be snugged up. Also, make sure there is a gasket underneath the bolt so it can seal properly against the cylinder head. The purpose of that bolt is to bleed air out of the cooling system if you were to change it. I included a link that shows the gasket with the bleeder bolt.It should not take a great deal of torque to get this bolt to seal, especially if you have a new gasket under it.Thanks,RSRBOB

When you say gasket you mean like a rubber ring that you put around the bolt?

No, more than likely, it is either a copper washer or an aluminum washer. Highly unlikely it is rubber.
