Id like to put my temp sensor where the low coolant buzzer sensor goes but due to the off thread im having issues finding something that works. Anyone know of anywhere i can find something that will work? Thread is M11.5x1.25mm

 

Its aluminum. Just rethread it

 

The water pump housing area is pretty congested. Belt running a inch away.
I think you'd be better off looking at throttle body water line, or go full out for accuracy without +- 2~5 Celsius difference in the radiator hose feeding to the pump.
And surely you don't want to rid of the low coolant sensor.
Throttle body line works well unless you're idling and not spinning the water pump.
They do sell conversion plug for the usual 1/8 NPT sensors, tho I have not come across thread that big for the temp sensor either of the oil or water.
You can always drill and tap carefully.
Just need to use good tape or sealing bonds.

Also the water level sensor is a KEY system to have. That will save your butt VERY fast, it takes no time for a hose to start leaking and pop and not much time after that. and you're looking at a rebuild.
