If we are talking about a charge cooled 4 pot Esprit the one at the front near the thermostat is for the gauge only. The other one is under the plenum and goes to the ecu. The ecu controls the rad fans.

Cheers for that :)

I work it out today when testing with free scan today , Had a good read and then look at engine and worked out and learned a few more things,

The wire had a bad contact with the sensor ,the one that sends temp to ECU. A little wiggle and it inproved, its going to get sorted today at some point and all earths checked / cleaned.

1 : Any ideas on which earths are more common to needing servicing ?

2 : Maybe its an idea to Replace Temp Sensors and replace thermastat as well as fan switch ?

cheers dave
