You need to drill and tap the head to ad the CJ style temp sending unit. Or you can run to the Pick and pull and find a 91-95 head and swap it out for that 97 head. The earlier head has the coolant passage already drilled and taped for the sending unit.

i like to do a little fab work but drilling and taping the head is a little over my comfort zone id hate to put it in the wrong spot. and really dont want to jerk the head off and replace it. is there an opion were i can slpice a hose with a piece of tubing and put the sending unit there or maybe drill a hole in the thermo housing and weld a nut on it to insert the sending unit.

Well, You could theoretically put it in the coolant hoses I guess. The only issue with that is that you would not get any coolant readings until the engine got to operating temperature and the Tstat opened. You want that to read off the coolant that is in the engine.

If you really wanted to avoid drilling the head or putting on a new head maybe you could get creative with one of the coolant drain plugs on the side of the block? They are much larger than the sending unit but maybe you can rig up an adapter?

No I do not mean the freeze plugs the block has one (maybe two) block drain plugs in it.

If you do not install a thermostat your jeep will never be able to get up to operating temperature. I personally would install one but if it works for you then I keep it that way.

i didnt even know those were there. does a temp sending unit just screw in or gotta drill and tap to fit. it get pretty hot 170/180 just takes a little longer to get there.

The Sending unit screws into the head. It is much smaller than the drain plug so I dont know how you would make it work but Im sure you can get creative.

Will a 3/8" ratchet with no socket on the end fit in there? That is how I usually get those things out.


*Edit* looks like Mike beat me to it.

I can't tell anything in reference to the size, but that square is the same size as a 3/8 or 1/2" drive ratchet/breaker bar without a socket on it.

Nope 3/8 was to big 1/4 was to small I had to go to a buddy's shop and barrow a specialty socket. 5/16 square head. Who knew? Never seen one before.
