* On the engine block: This is a common location. It's often near the thermostat housing or on the cylinder head.
* In the intake manifold: Less common, but possible, particularly on later model years or specific engine types.
To find it *precisely*, you'll need:
1. Your van's year and engine size (e.g., 1995, 5.7L Vortec): This information is crucial because sensor location varies significantly between engine types and model years.
2. A repair manual specific to your van's year and engine: A Haynes or Chilton manual (or a digital equivalent) will have diagrams showing the exact location and even instructions for replacing it.
3. Consult online forums specific to Chevy G20 vans: Search online forums (like the Chevrolet forum on sites such as cargurus.com or others) for your specific year and engine. Someone may have already posted a picture or description of its location.
Looking at diagrams in a repair manual is the most reliable way to locate the sensor. Trying to find it without a proper reference can lead to wasted time and potential damage.
