GMC Sonoma No heat Problem
I swapped out the intake manifold because of a leak and then the thermostat because of no heat still have no heat and I see I have a bleeder valve how do I get to it to untighten it is there a certain wrench or a socket I'm unaware of?
Thank you

At least I believe this is a bleed valve right underneath where I put the thermostat in. notice the square nut, is that a bleed screw because if not i already let her run for about 45 min with the radiator cap off and still no heat, the pipe shown there also is extreamly hot so I'm running out of ideas.

ok, it is a port for adding a sensor or hose connections.
rev the motor to 2500 rpm till you get heat. then it is bled. watch the coolant level
