Coolant Temperature sending unit

[THUNDERZ]

Does anyone know what a stock L6 temp sending unit is supposed to read in millivolts in relation to the coolant temperature?

The ohms value is what changes as the coolant heats up. When I was fighting with mine last year I hooked it up to an ohm meter and used a digital thermometer. I recorded the following change in ohms as it heated up in a pan of water:

 

23 C/73.4 F = 400 ohms

25 C/77 F = 386 - 365 ohms

30 C/86 F = 302 - 290 ohms

35 C/95 F = 238 - 228 ohms

40 C/104 F = 190 - 183 ohms

45 C/113 F = 153 - 149 ohms

50 C/122 F = 123 - 118 ohms

55 C/131 F = 98 - 95 ohms

60 C/140 F = 84.1 - 80.3 ohms

65 C/149 F = 69.0 - 67.2 ohms

70 C/158 F = 56.5 - 56.0 ohms

Thanks Dave...I was just double checking it since the coolant temperature reading I was taking and the engine temperature gauge werent consistent.
