How do I get this plug out of the motor it doesn't have any kind of a head on it and I don't want to tear anything up

I'm trying to put a water temperature sensor in my tractor and I understand this is where you do it but I can't get the plug out I'm scared to beat on it any advice would be great thank you

Appears to be a hex drive pipe plug. If so, you will need the proper size Allen wrench. Dig out any debris and get the wrench all the way in before trying to turn it.

Okay thank you I'll try that there is some crud down in there can you look at it from the top it just looks like a circle
I wonder if I need to pull that Chrome thing out of the middle or not

Try different sae and metric Allen wrenches to see if you get a fit. It could be that the hex starts a little bit down in there. You are being careful and that is good, you have one good chance at getting it out and if that fails it gets ugly.

It also might have been installed using Locktite, so you might have to put some heat on it from a flame to loosen the Locktite's grip.

First thing to do. BUY one of those plugs !
2nd, find the proper , new METRIC Allen key that fits it. JAP engine 'has' to be Metric.
3rd, heat the one in the engine real good,odds are it will have 'thread sealer'
4th,try to 'break it free' say 1/4 turn. when it moves, go 1/4 turn out, 1/8 turn in , repeats until totally free and out.

If it doesn't want to come out there is an EASY Plan 'B'. Buy a $6 rad hose/sensor unit.Cut rad hose,install,clamp , then screw 1/8thNPT sensor into it.
