if i understand your question, no such wire exists. the thermostat is not electronic. it opens and closes when the temperature causes the spring to expand or contract. what seems to be worrying you may be no more than a coolant temperature sensor that has gone bad. if your car hasn't overheated in 30 minutes at idle, your thermostat is fine. hope this helps you.
The wire that you are probably talking about goes from the temperature gauge to the temperature sending unit which is on the passenger side between the fuel injectors etc. If your gauge isn't working and it is the needle type you can pull the connector off of the sensor (make sure you get the right wire, it's a single) and have someone turn the ignition on as you hold the connector to ground, the needle should move all the way up...if not the gauge or wiring is bad. ...........
Is vehicle actually overheating? Could be a bad temperature sending unit or gauge Check temperature with a thermometer If thermostat does not open vehicle will overheat
Raise or lower the temperature to change the reading on the thermostat.
what your looking for is a heat relay sensor its located right in front of the thermostat houseing just follow the top hose comming out of your radiator all the way back till it gets to the top of the thermostat and about three inches towards the front of the vehical there should be (heat sensor) looks like a bolt with a wire sticking out of it diconnect that and take it out and replace it with a new one that should solve your problem.
Depends on car, example: it could be 180 - 195. There is the rating on thermostat
The 1999 Cadillac normal coolant temperature gauge reading should be 180 degrees. A 195 degrees thermostat could be used, causing the temperature gauge to read 195.
195 to 210 what temperature thermostat do you have
Could be that the thermostat is stuck open, new thermostat fixed my 2001 Dodge 3500. If your temperature gauge is not reading warm enough, could be the thermostat.
If the thermostat is open, the ohm reading will be O/L.
If your coolant level is fine but your engine temperature gauge is reading on the cool side all the time , your thermostat is probably sticking open. ( or you have no thermostat , or the wrong thermostat - one that has too low of a temperature range ) Anybody else have any ideas ?
Depending on the engine, the coolant temperature in a Cadillac could be from 180 to 195 degrees. The thermostat can be changed to give a lower or higher temp reading.
At least five minutes (same as if you were to eat or drink something then take an oral temperature reading).
A bad thermostat is one possibility.
If the temperature gauge is reading below normal operating temp after driving a little while it may be that your thermostat is stuck open. I replaced my thermostat and it fixed mine.
Head gasket. Do block test for gases in coolant
If your temperature is taken orally, the temperature of your drink can change the reading on the thermometer. If your temperature is taken rectally or in the axilla, then it wouldn't matter how long it as been since you drank something.
You can get a thermometer and see how hot it is coming out. Match this number up to the thermostat reading.
Be careful there is a temperature coolant switch mounted next to the thermostat housing. I thought this was the sensor and replaced it by mistake. There is another sensor.
reading thermostatreading thermometer
Either there's a problem with your sensor, or there's a problem with your thermostat, and it's giving a false reading. Your engine temp may actually be high, as well - what you see on the gauge is the temperature of the coolant, not of the block itself.
An open thermostat would keep the engine from heating up to normal operating temperature. The sensors effected can only report what they sense. The "check engine" light may throw a code like "P0116" (engine coolant temperature circuit range/performance problem).
it is a psychological process because it connects to your brain
When temperature increases so the reading shown also increases.
Add 273.15 to convert degrees Celsius to Kelvin.
