From my experience, the “normal” range should start around the temperature that the thermostat should open, whatever that range is. That information is “probably” disclosed in the FSM (factory service manual) but I have not found it yet. If you want to get an actual temperature to correlate with the reading on your gauge, get one of those non-contact infrared temperature readers. I usually take a reading from the header tank on my radiator. But it is interesting what various areas on the engine or under the hood read. The last one I bought, I got it from Newegg for $24 bucks plus shipping. See: http://www.newegg.com/Product/Product.aspx?Item=N82E16896268001 It is a very useful tool that can be used for many uses. From Big John Mc Adams (In 100 degree SoCal) From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of kmaniak@xxxxxxx There are no numbers on the gauge because the gauge and sender unit are not calibrated to display absolute temperature. I do not know what absolute temperature is represented by the top part of the gauge by the H. Whenever my gauge climbs up to the top, I turn off the engine and pull over because the coolant temperature is "too damn hot".
