cummins water temp?

From : duncan williams

Q: got a 96 2500 with 12 valve cummins. the water temp gauge was slowly walking back and forth between 0 to 190 degrees f. i took it to the shop - they said it needed a new sender. got it replaced. now the temp does not walk up and down - it reaches a steady state at about the 10 oclock position and stays there. the 12 oclock position is 190 degrees f. im told diesels are cold natured but shouldnt this engine be regulated to 190 degrees f thru the thermostat normal air temps right now are in the 90s.... .
