2002 5.9 magnum. Installing a Hughes Airgap intake manifold with fuel injection. But w

hat goes in this hole next time the thermostat housing. It's threaded, goes into the manifold. Not sure what goes there. My mechanic that was working on the engine rebuild died so we're trying to finish this up before the shop it's at closes its doors. Have the radiator, fans, ac to go. Something goes here, but what?

 

Looks like the spot for the temperature sensor.

 

On older engines, (97 and down?) there were two temp sensors. One for the gauge, one for the PCM, on later trucks, like yours.... there is only one. If you already have your sensor installed, just put a pipe plug in that hole.

 

Thanks guys, that was what we decided too. Extra hole for temp sensor and to plug this one.

 

My airgap has the same thing, funny thing is though mine uses the hole that you plugged and not the bigger one i just have the old sensor in that hole but not plugged in
