i got a new head cause mine was warped all to hell and i was wonder what plug fitting i need on the driver side under the intake to the right of where the fuel filter housing is built into the head for the coolant passage there cause my old head had nothing that plugged in there or am i missing something?? please help thanks

 

That is where your temp sensor goes. Not sure how the old one got a temp reading if it didn't have one. I don't know what thread it is but it is big, maybe 1/2" or 3/4" NPT.

 

i found a plug it was the same as the fitting next to the thermostat but no there is one for the temp sender and one to the left about 6 inches away this is why i was confused??

 

temp sending unit is drivers side rear
the one next to tstat is for the jiggler to remove air from system

 

ok thanks man
