2000 GMC Sonoma Repair Question
GMC Sonoma No heat Problem
never seen a bleeder. what motor and what year manifold did you use
got a picture of the manifold and still no bleeder. can you post a picture??
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
