it is the water temp sensor that is in the wrong place (i think) where is it.
is it the blue sensor above the oil filter and under the throttle cable area?

check your oil temp on tickover to see if its going up high. if it is then pull off the bottom hose to the heater matrix and i bet it will swallow some more water. this also happened to me after my rebuild.just keep an eye on your oil temp

are your heaters warm?
