My temperature sender broke off at the base of it so im
unable to get it out and replace. I started drilling it out but decided to stop because I have never tap and rethreaded anything before. There is a little bit of the sensor laround the threads left.

Obviously the coolant system won’t pressurize because coolants leaks out of that hole now. Can I seal this hole with some kinda epoxy and get an oil dipstick temperature gauge? What are my options? And does anyone know the thread size and pitch of the sensor on a F2?

 

No more drilling needed. Should be able to remove rest with screw-extractor. This preserves threads.
