Thanks for everyone on the spark plug input... I did go with the NKG's TR55 fired up and ran smooth.

Now I am proceeding to replace the Radiator and have the new one from Radiator dot com 130 bucks deleivered (awesome) but I have to remove the old senesor to Install it in the new Radiator. I removed the clip put I am not sure how it comes off?? I dont want to break it. Thanks for the help!

How does it come out from the radiator? The new one just has a hole but with no threads?

* It did come with a couple brass fiittings but I am not sure what those are for maybe if different size Tranny cooling.

It just snaps in.
It has an O-ring seal.

Wiggle and pull, wiggle and pull, then when your hips get sore from all the wiggling, try wiggling the SENSOR and pulling. It'll come out. Lube the o-ring (saliva will work) before putting it into the new radiator.

It looked like it was a bit stuck or possibly had a fitting on it.

I took a GM door clip tool worked it around and pried it up! Onward

Thanks!

You wouldn't want to give your rad a STD!
Use some petroleum jelly or silicone lube.........even KY would work.
