Need to plug rear coolant sensor

[Ben824]

I bought a 92 YJ engine to drop in my 97 XJ. I need to plug the rear coolant sensor hole, what have tall done for this?

Buy a new coolant sensor and stick the old coolant sensor in the open hole, or a pipe plug will probably fit.

1/8 NPT plug from any hardware store

To add to ehall's comment, your local Carquest/AAP, Napa etc should have this in their EDE aka Edelmann section as well. There are usually a couple different head styles, such as square, hex, allen, etc.

Thanks guys! I picked up a brass 1/8 NPT plug at Ace Hardware when I went there to get some bolts to help bolt the engine to the new engine stand.
