Re:Coolant temp sender/82 coupe
Huw Powell requested the location and voltage of the coolant temperature
sendor for an 82 Coupe...
The temperature sender is by no. 1 spark plug below the power steering
pump support bracket.
I believe the sensor resistance changes with temperature - mine measures
75 ohms at normal engine temperature. With the sensor lead disconnected
(infinite resistance) the gauge reads full cold.
Your problem may just be a poor contact between the connector and the
sensor - this happended to me on the UrQ where the sensor provides an
input to the computer and caused all sorts of problems - it looked clean
to look at but a resistance check showed a bad contact.
