  1. Multiple ECT sensors?

    99-03 7.3L Powerstroke Problems
    I recently noticed my coolant temperature was over 500 degrees Fahrenheit when I had just started the engine. Great! I replaced the ECT sensor. It's located just to the left of the thermostat housing. I attached a photo to be crystal clear of what I replaced. Now my temperature is reading...
  2. Can bad thermostat cause rough idle and performance?

    6.0 Motor problems
    I am now to this forum. I just noticed that my temp gauge is not moving past the first notch. Looked at coolant tank and it is low. When the truck starts to warm up it runs/idles rough and loses power. Can a bad/stuck thermostat cause this?

    General 6.0L Discussion

  9. EOT/ECT Temperatures

    General 6.0L Discussion
    I have installed an Edge Evolution CTS so now I can actually see my oil and coolant temperatures. Typically the run 6-8F degrees different. I have heard you want no more that 15F difference so I am guessing this is OK. My question is that my coolant in in the 183 F range and the oil is running...
