The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.

2006 Chevy Trail Blazer 4.2 liter. Where is the coolant temp sensor located?


Since its an 06, its located rear right side upper end of engine...if it was an 05 or older , its located right above the thermostat housing...I said the later because you will sometimes have the correct model year but the manufacture put in a previous model years engine depending on actual build date...

Temp gauge not working 2004 cadillac cts


It would have to be on a scanner to see if the PCM is sending a signal(most likely is, other gauges working). Instrument panel gauges do go bad. And they can be replaced.

Gs300 coolant is bubbling in resevoir,but temp is fine ?


Get coolant temp sensor checked.

Get the coolant pressure tested, its definitely leaking coolant. You will need to get the coolant running line.


Pressure test will help you to know from where exactly coolant/refrigerant is getting leaked.

2003 Cadillac CTS at 225,000 miles Code P0128 comes up periodically. Any solution other than a thermostat change at $400 plus?


First off who ever said $400 to change a thermostat is trying to rip you off. The actual part is like $20 bucks max and its so easy to change. I can guide you through it if you would like.

The P0128 code is Coolant Thermostat Malfunction.

These are the possible causes for this code:
- Insufficient warm up time.
- Low engine coolant level.
- Leaking or stuck open thermostat.
- Malfunctioning engine coolant temperature sensor.

These are the possible quick fixes:
- Top OFF Engine Coolant
- Replaced Thermostat

Hi I own a 2003 Cadillac CTS I am getting a check engine light error light with code P0128 and my heat is fluxuating up and down I have already installed a themostat. What are my options

1-Low engine coolant level
2-Leaking or stuck open thermostat
3-Faulty cooling fan (running too much)
4-Faulty coolant temperature (ECT) sensor
5-Faulty intake air temperature (IAT) sensor

Check coolant level
Check to make sure thermostat is functioning properly Check the Cooling fan Check the ECT sensor Check the IAT sensor If all else fails replace the thermostat
