Are tthe low coolant level sensors as found in the radiator header/expansion egg carton bubble bbottles found in E-Series and AU's the same? I relise in AU they are mounted different and possiably a different bottle, but is the sensor the same? Do they fit into the bottle the same? If not, can an AU sensor be used on an EF orr would the resistance be different (shhouldn't be as it's just a on/off switch triggered by the level that enables thhe circuit to complete hence the light on the cluster illuminating)?

the sensor is the same yes.

well since u work at an auto spare shop
LOOK on the computer sheesh


and yes they are the same
