I need the part #s for the coolant temperature sensor in the side of the block (drivers side) I broke mine putting headers in... also need the part # for the AIR tube (the stainless steel tube) for that side. Or can I just find something that fits at the hardware store and use that?

 

These are on shoebox site, in the parts numbers page:
Temp gage sensor in head:25037332 $10.30

I don't have the AIR tube # but it would help if you post year of the car..

Do you mean the stainless pipe that screws into the exhaust manifold that goes into the black diverter valve (like upper left in this pic ? If so, GM PART # 12550779 is your part.

 

Yep, thanks shoebox. Your site's the best

Found the sensor at AutoZone, gotta order the pipes through GMPD.
