Normal Operating Temps

Hey all,

Wondering what you're seeing for oil and coolant temps. I had some work done on the thermostat and I'm concerned about the new temps. Before the work was done it never went above 195 for the coolant and over 204 for the oil. I'm seeing both matching around the same now in the 206-210 range. Is that a little high? Ambient air temp is 60. Under the hood was maybe 80.

Could their be air in the system? Just concerned why the temps would change so much.

The reading on mine (3.6L, limited) is 195 for oil and 185 for transmission in NE winter.
I have the Torque App obd reader. You can read the temps on there. I have a limited 2014 Ecodiesel.

For the next poor soul that has this issue or concern, since people don't like to answer, it turns out the Chrysler spec is these thermostats open up at 195 and coolant should run between 195-210. The thermostat I had installed was a revised part number that promotes better flow. My old thermostat was apparently both flowing as well. Seeing coolant and oil that are the same isn't a concern apparently, and the normal range for both oil and coolant in a non towing capacity is between 195-210. Hope this helps someone else

From the Chrysler VM 3.0 Engine Service Manual:

"The 3.0-liter diesel uses a water pump/thermostat assembly. The thermostat is located at the top of the water pump housing. The thermostat is a wax pellet design with an opening temperature of 107 C (225 F). The thermostat is integrated into a housing. The thermostat and housing are serviced as a assembly."

Then again, my manual is over a year old so the specs may have changed since then.
