* On the intake manifold: This is a common location. The sensor is often screwed into the manifold itself.
* In the engine block: Less common, but possible. It would be located in a threaded port in the engine block.
* On the cylinder head: Another possibility, typically screwed into the cylinder head.
To find it, you'll need to:
1. Consult your vehicle's repair manual: This is the most reliable method. The manual will have diagrams showing the exact location of the sensor for your specific year and model.
2. Look for a single-wire or two-wire sensor: The CTS is usually a relatively small sensor with one or two wires connected to it. It's often located near the thermostat housing or other coolant passages.
3. Use online resources: Websites like car part retailers (e.g., AutoZone, Advance Auto Parts) often have diagrams and parts locator tools. You'll need to enter your vehicle's year, make, and model.
4. Search online forums: Forums specific to your vehicle's make and model might have pictures or discussions about the CTS location.
Without knowing the specific year, make, and model of your 4.3L engine, I cannot give you a precise location. Providing this information will allow for a more accurate answer.
