Why would you want to do that? What happens when the engine does run hot and you blow it up? Why not just find out what is wrong and fix it? It's probably just a sensor or the alarm is bad.

Ok, just look on the head and you will see a wire coming out of the sensor, I think the wire is brown but i'm not sure. Just trace the wire back and disconnect it at the bullet connector. To test the alarm disconnect the wire and ground the wire coming from the wiring harness to the block with the ignition switch on. If the alarm sounds when you ground the wire then it is fine and the sensor is probably bad.
