Ecodiesel USA custom built 190 thermostat
 
This thermostat can only be used in tuned Ecodiesel’s or it’ll set a p0128 code. Make sure your tuner removes this code.
 
The factory thermostat is 208 degrees which is for emissions purposes only, and quite frankly way too high for the Ecodiesel engine.
