Water Temperature Sensor specification?

[Sunray]

I wanted to check this part.

Its sensitive to temperature of my hand and runs from 800ohms to about 100ohms room temperature to boiling.

Before I fit this back, I wanted to know if there was a spec for this part, couldn't find one apart from this detail which is for a Vanagon 2l injection.

I would say its working OK, just wanted to check specification but none seem to exist.
