In a 2008 Chevy TrailBlazer with the 4.2L engine, the coolant temperature sensor is located on the right side of the radiator. It monitors the coolant temperature as it flows from the engine to the radiator. Monitoring the temperature gauge is crucial to prevent overheating, which could lead to lasting engine and component damage. Regularly checking coolant levels during oil changes and ensuring the coolant reservoir is topped up will help maintain optimal cooling performance in your vehicle.
Can you please demonstrate the location of the temperature sensor on a 2008 Chevy Blazer 4.2 by providing a picture?
Alright, here's a rephrased and simplified version:
On a 2006-2009 Chevy Trailblazer with a 4.2 engine, you can find the Engine Coolant Temperature (ECT) sensor at the passenger side of the engine towards the rear. Just locate the valve cover bolt on the passenger rear side and look right below it to find the ECT sensor. Unfortunately, I can't upload pictures here, but I have diagrams to help. For the 2002-2005 Trailblazer with the 4.2 engine, the ECT sensor is situated on the driver side near the front, behind the alternator and directly above the thermostat housing.
Where can I find the temperature sensor for a 2008 Chevrolet Blazer?
How can I change the heater hose situated behind the 4.2 6-cylinder engine and also swap out the temperature sensor?
Hey there!
The coolant temperature sensor can be found on the radiator, situated near the front of the engine.
In 2008, Kenneth F Miller worked on the transmission of a Chevrolet Trailblazer.
For the 2005 and earlier Trailblazer with the Envoy inline 6 engine, the coolant sensor, also known as the ECT sensor, is located behind the alternator on the driver side of the engine block. It can be quite challenging to access. However, from 2006 onwards, the sensor is situated on the passenger side of the engine block closer to the firewall. The user WBROCKSTAR is accurate in this information, while others may be mistaken. A video on YouTube demonstrates how to replace the ECT sensor on a 2008 Trailblazer by removing the passenger side wheel.
It can be found on the right side of your vehicle, between the firewall and the engine, just behind the exhaust. You will need to remove the exhaust to access it.
