Water temp with a 180 tstat?
This is to all you who run a 180 tstat. I just put one in and was wondering what you temp is. I have the big ol' gauge and I am running with the needle around the 2 in 200 which I figure to be 180. It goes from one side to the other. I am just curious cuz it was always around 210.

RE: Water temp with a 180 tstat?
This is were mine runs in the summer time with a 180 t-stat. When I had a 195 t-stat, my needle covered about half or more of the "2"
Now that it is winter, my needle sits even lower (about right on that next line lower).

RE: Water temp with a 180 tstat?
On my 1995 the needle stays midway between the left mark and 200 in the center.
The OBD-I scanner shows the temperature at cruise to be 183 with the Air Conditioning
off and it goes up to 187 with the AC on.
But 1995 was the last year before things changed over to OBD-II electronics.
My truck has one sensor screwed in beside the thermostat housing for the dashboard
temperature gauge, and a second sensor screwed in that goes to the PCM computer.
If electrical connections between the sensor and the PCM computer are dirty or corroded
it will throw the reading off.
Later Ram trucks just have one coolant sensor.

on the 180 tstat... when your motor is running that cool with lower degree t-stat.. doesnt that trick the pcm into thinking that the motor isnt warming up at all and keeps dumping in extra fuel during the injecter pulses to try to warm it up .. essentially ruining your MPG?

RE: Water temp with a 180 tstat?
I still average over 15 mpg. My mileage dipped some when I installed the t-stat, but I also installed the programmer at the same time. Then over time, it has come back up to around 15-16.
I've also read the the engine will throw a code if it doesn't reach a certain temp (I think someone posted 170). I believe this to be false (or at least false in the sense that it might not be based on the reading I see in the cab on the temp needle). When it is really really cold outside here in the winter (temps around 0), there are somedays when my needle barely moves off 130 the entire drive to work. That has nothing to do with a 180 t-stat, it would do the same with a 195 t-stat.
