Does anyone know the wrench size required to remove the 1/2" water temperature sending unit? Have searched to forum, but have not been able to find it. Thanks in advance.

DO NOT GO AFTER THE SENDING UNIT WITH A OPEN END WRENCH. It will round the soft brass. I used a long closed end wrench and a hammer and the sending unit loosened fairly easily. Start the engine and let it warm up to operating temperature then, while the engine is running, try to loosen the sending unit. The heat + vibration will help it loosen.
I don't remember the wrench size. You can span the sending unit with a open end adjustable wrench then measure the jaw opening to get a rough idea of the proper wrench size.
