Leaking around sensors on thermostat housing

[Mike92STX]

I have a 2004 with a 4.0 and I just noticed that coolant is leaking from around the sensors on the thermostat housing. It is an aluminum housing, I know that shouldn't make any difference. Is there a way to correct the leaking? I haven't done anything yet, I just noticed it this morning. Any suggestions will be appreciated.

The sensors have o-rings on them and are held in with a clip. You should be able to replace the o-rings with new ones that are not all hard and shrunken up.

I have thought of that, I haven't checked them yet. I mentioned that I installed a aluminum housing, I think I got it from Rock auto but I'm not sure. It's not very old because I had a remanufactured motor installed a couple of years ago and I installed the housing then. I'm thinking that it may have not come with the sensors so I might have put the old ones in, but I don't remember for sure. I'm of the age where I don't remember some things as well as I used to.

I went to NAPA to get some new sensors, and they say there is supposed to be a different sensor than i have and when I got home, I looked, and the connector is the same on both of mine. I have never changed the connector, but I did buy it used. What is correct connector for a 04 4.0 sohc.
