Your engine can have a bad thermostat and pee water like a 6 year old. The water discharge for the "pee" indicator is before the thermostat in the water flow path. Does the alarm sound after the engine has been running for several minutes or right away? Does it only alarm on the flush or also does it in the water? Your engine has a 110 degree thermostat in it. If you have a laser temp probe you can shoot the laser at the thermostat housing and see what it is reading, then progressively go around the block and probe all the areas and look for any hot spots. Do these checks and then we can talk about next steps.
