I would like to know what is the normal running temperature!
Mine shows:
- Normal driving not pulling EOT and ECT 180 degree
- While towing my 13k trailer EOT and ECT can reach 200-220 some time.
The thermostat begins to open at about 190*F to 195*F and is not fully open until about 215*F to 219*F. The PC/ED manual states that the PCM will begin to defuel when the ECT exceeds 221.
