Default Engine Coolant and Temp Gauge Sensor

I’m going to be replacing my engine coolant temp sensor and temp gauge sensor. I’m not sure if any sealant should be applied to the threads to prevent leaking. The coolant sensor does come with a copper washer. The temp gauge sensor doesn’t have any washer.

What does everyone think? Do they need sealant on the threads? If so what kind of sealant should be used.

I’ve never used any sealant or gasket maker on either one…

It’s a plug ‘n’ play part.

I don't have any sealer or a crush washer on my temp sensor either.

For screw-in senders, I use a dab of Permatex #2, making sure to keep the business-portion of the sensor clean/clear.

Thanks for everyone’s response.

I managed to lose the U square paper clip like holder for the engine coolant sensor connector. Anyone know a part number for that?

I've lost several of those over the years. You can make a new one out of a paper clip.

Thanks for the tip. I actually got lucky and found it. I started the truck up and it must have shaken loose because I found it on the floor beneath.

Hi, new to the site! My temp gauge on my 96 V6 is not working. Where did you get the new parts from ? Looking to replace mine as well in the near future.

I got both the temp gauge sensor and ECU coolant temp sensor from Rock Auto but I had issues with both. The one for the gauge didn't work at all. The computer threw a code for the coolant sensor. Maybe I just got unlucky. But I ended up putting my old ones back in. The gauge worked before it just showed low when heated up. My original coolant sensor never threw a code I was replacing it because I thought it might have been bad for another issue I was having. I tested my old coolant sensor before reinstalling and it tested good.

I would test your gauge sensor circuit before replacing the sensor to make sure you don't have a problem there. The gauge temp sensor only has one wire. Unplug the wire from the sensor and rig up some wire to connect it to chassis ground. When that wire is grounded your gauge should be pegged past hot on the gauge.
