I am trying to find out what plug this is. It has a slow coolant leak and I need to fix it. The plug is located behind a mounting braket which made it difficult to find. Any suggestions would help.

That's a clear picture but I can't locate myself. Have you got a shot from further back? Or a description of where it is?

 

I found out today that this is a non-servicable part of the throttle body. It is located just behind the air intake on the passenger side. I had to move a mounting bracket to get to it. The mounting bracket covers the lower hole/plug. My choices were to buy a new throttle body for 300.00 or JB weld it. Guess which one I tried? I'll post the JB weld results here.

 

why not just get a used TB off ebay? i've seen a guy who broke a spark plug torque it down. well he couldnt pull it all back out so he just JB welded the spark plug in it.. well it was outa warranty:-p so guess who bought a new head

 

gbarker, you can simply take off and plug up both hoses that go to the throttle body from their source. Those cooler lines were to aid in heating up the incoming air. You don't need them. Everybody I know does away with them when they start to give them trouble. Or just get some hose and connect one end to where the hose comes from the heater hoses and the other to the top of the intake(where the bottom hose goes to) then just route it out of the way. Either way, you'll be fine.
