what sensor is this? Hey guys. I just finished installing a set of long tube headers on my lt1 firebird. and I got a little...aggressive with the install at some point. But the upside is, only a few things broke. 
As you can see in the attachments on the driver side of the engine block, one pin snapped off as there are supposed to be two. I think this is the engine temp sensor, or is it the oil temp sensor? crank pos. sensor? I'm not sure. It's a 96 trans am. Also a vacuum line connecter broke, but I think i know what that's called. but just in case, I'll throw it in with the attached photos. Any knowledge on these two would be great.

That would be the coolant temp sensor, this particular sensor just operates the dash gauge, there is another one in the water pump itself, when you buy a new one make sure that you have the correct item.

The other part is the vacuum check valve for your HVAC system. Its a three nipple, vac on one side, the other two go to the HVAC and reservoir...I've seen them at Advance Auto but others may keep them in stock.
