[thatone1320copcar]

Hi everyone, i cant get this coolant temp sensor out of my manifold, broke the top of it when i was replacing my intake manifold gasket. it wont turn and i tried everything from a socket(when one fit) to vice grips. and i cant seem to get it to turn. i even heated the surrounding metal and nothing. any ideas?

I would say just keep picking away at it until you can collapse the threaded area in on itself. Clean the threads and any trash in the water jacket....install new.

i ended up using a combo of heat, pb blaster, and a big easy out attached to a large breaker bar

put some anti-seize before putting your new one on.
