Using an adapter bushing puts the sensor out of the coolant flow and almost guarantees a small air pocket around it, resulting in skewed temperature readings.\u003c\/p\u003e\n\u003cp\u003eI ran into this issue myself and found that nobody makes the correct sensor for this application; so I made one.
