I have a 2001 cherokee and I just replaced the head with a j&c enterprises head but there's an open bolt hole toward the back of the head right in front of head stud #14 and I have no idea what goes there I'm hoping some one on here does.

 

Post a picture

 

 

Could be a temp sensor port. Just plug it

 

+1 That's where the sensor for the temp gauge goes on my '96.

 

On my 2000 its just has a plug, I dont know what size sorry.

 

I had a 2001 and replaced the head with a tupy. Both of them didn't have plugged holes

 

Thats a pic of mine..Clearwater head.

Also for the life of me i can not figure where this goes
