Where is the coolant temperature sensor on a trailblazer?
Raise the TrailBlazer off the jack stands, using a floor jack, and remove the jack stands. Lower the SUV to the ground. Find the coolant temperature sensor on the front of the engine block, just behind the alternator. Pull upward on the locking tab on the coolant temperature sensor’s wiring harness, and pull the wiring harness from the sensor.
Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
Where is the coolant below temperature sensor GMC Envoy 4.2L?
GMC envoy 4.2L can you tell me where is can find coolant below temperature sensor. There is no such sensor. I am guessing that you have a check engine light with code P0128- coolant temp below thermostat regulating temperature. This code is cause by either low coolant level, or more likely- a bad thermostat. Where is the throttle body?
Where is O2 sensor located on 2002 TrailBlazer?
There are 2 diverter valves and 1 vacuum control valve / solenoid. O2 sensor would not cause AIR code. Where is 1997278 evap valve located on 2002 trailblazer?

How do you replace a sensor on a trailblazer?
It is easiest to replace by getting the Trailblazer up in the air, either on a lift or on jack stands. There is one electrical connector on it, and one hose connection. It is usually retained to the bracket by a small, bendable metal tab that you can bend out to remove it and then bend it back in after the new one is on.

Where is the coolant temperature sensor on the thermostat?
Coolant temperature sensors are usually near the thermostat housing. Code 128 is set from the readings from a properly-working coolant temperature sensor. I tried multiple times to resize the image, but it always comes out the same. The CTS is item number 1.
What kind of engine does a 2005 Chevy Trailblazer have?
The 2005 TrailBlazer — the last year before it replaced the Blazer altogether — had a 4.2-liter six-cylinder engine as standard and 5.3-liter V-8 engine as an available option. Replacing the coolant temperature sensor on either engine is a similar process, with exception of the coolant refill procedure.
How to cool a trailblazer 4.2 liter engine?
Start the TrailBlazer’s 4.2-liter engine and hold the engine’s idle at 2,000 to 2,500 rpm until the temperature gauge reads about halfway. Allow it to idle for about three minutes, then shut the engine off. Allow the engine to cool until it is cold to the touch and check the coolant level in the coolant reservoir.
Where is the thermostat located on a 2004 Trailblazer?
Where exactly is the thermostat located on a 2004 trailblazer. Some sites and YouTube say its located behind the alternator and others say its located attached to the top radiator hose connected to the engine. On a Trailblazer- thermostat on the 4.2L straight six cylinder engine is behind the alternator.
Coolant temperature sensors are usually near the thermostat housing. Code 128 is set from the readings from a properly-working coolant temperature sensor. I tried multiple times to resize the image, but it always comes out the same. The CTS is item number 1.
Why is my Chevy Trailblazer coolant not working?
It is triggered when your Chevy Trailblazer ‘s coolant temperature fails to reach the proper operating temperature. It’s a generic powertrain code, which means that regardless of who manufactured the vehicle, it’ll have the same meaning (1996+).
Why does my Chevy Trailblazer have a trouble code?
Here are the symptoms associated with this trouble code: Lack of heat – The biggest symptom of the P0128 trouble code in the Chevy Trailblazer is going to be lack of heat. When the thermostat doesn’t bring the engine all of the way up to the proper operating temp, it means that the water going through the heater core isn’t as hot.
What should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.

What should I do before replacing my coolant temperature sensor?
Make sure to clean the sensor’s insert area before you reinstall the temperature sensor. In some cases, dirt, debris, and other particles will impact the function of the coolant temperature sensor, so you want to make sure you have a clean area before installing the new one.
What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
