Its actually a good location being under the thermostat. Many decades ago I owned a Ford Escort and it had the temp sender above the thermostat. Just out of Rotorua it started making a boiling sound. Guage saying cold. Radiator stone cold as well. The cause was a blown head gasket which had caused bubbles under the thermostat so it never opened. Pulled the thermostat on the side of the road refilled the radiator with water from a drain and drove back to Wellington

that sensor controls the overdrive and won't allow it to shit into overdrive when the engine is cold if it's auto, if manual you don't need it

Bugger too late its gone and temp sender is in there, must mean if disconnected tells auto its hot enough because it still goes into overdrive. thanks for the info, could you tell me the sender at the back of the thermostat, and if i read it right it controls how long the glow plugs stay on and advances timing? mine has a broken wire does it mean its sending a signal advancing my timing on all the time? its starts ok usually first time if i wait to hear the little click usually just after light goes out :lol:
