That doesn't look anything like what I'm talking about. The thermostat sits inside and the bolt screws into the housing the the thermostat sits in
yes that is correct
ok well will it make the truck run hot? I changed the thermostat and it was running hot, but I took the thermostat out and it is fine. I tried to replace this part, but they didn't know the name of it at the parts store. The catalytic converter has been taken off so do I even need thes lines anyway?
