I bought a new waterpump and noticed the threaded bolt isn't in it (see the photo). Should I buy a new bolt and thread it in the new waterpump or remove the old bolt? How would I remove old bolt?

Thanks for any help.

 

Is the hole in the new pump already threaded ?

 

Yes it is already threaded.

 

Just put two nuts on the stud, tighten them toward each other, then wrench it off as if it had a head on the bolt.

 

Worked like a charm! Thanks!

 

Glad you got it off. Sometimes you may need a little heat. Not this time.
