EOT and ECT TEMPS

[2005powerstroke]

What is the most temperature spread you should see between EOT and ECT for the 6L diesel.

I have heard no more than 15 degree spread but I don't know if that true or not.

Thanks

Its true. If you're seeing more than a 15 degree difference, you have a problem with your oil cooler.

If I'm seeing a 20 to 30 degree spread should I be highly worried.

If so what else should I have done when I get this fixed.

Yeah man, that's in dangerous territory there. I would get the oil cooler rebuilt ASAP. I would also do something about the EGR cooler while you're at it. If you don't have to worry about emissions, delete it. If emissions is a concern install the Bulletproof diesel upgraded egr cooler and never have to worry about it again.

Another thing I would recommend is to have your cooling system flushed with VC-9 BEFORE the cooler is rebuilt and replace the Ford Gold coolant with a good ELC coolant (red) from Cat, Rotella, Fleetrite, Texaco, Zerex. The Ford Gold coolant is a major factor in your oil cooler clogging up due to the silicates and the high temps seen in the EGR cooler. Don't let the dealer tell you otherwise. Adding a coolant filter isn't a bad idea either.

Where do you take your readings for the EOT and the ECT?

[PGreenSVT]

They are sensors that the PCM monitors. I use an Edge Insight with will display anything the PCM monitors. If you don't go that route you have to install separate gauges to read the temps. Highly recommend the Edge Insight (including the new CS and CTS). Best bang for the buck in engine monitoring solutions.

Some good information right there.

Not to high jack the thread, but I was wondering...Has anyone noticed a higher temperature difference when the weather is hotter. I notice a temp difference of about 13-14 degrees when it's around 100 degrees and a difference of 8 - 11 degrees when it's around 80. ECT is around 190 and EOT varies from 298 to 204. Is this normal and have others seen something similar?

[Snake]

Yes, that's normal. And you'll also see a bigger difference when towing.

Here is mine..I havent "permanently" installed it yet because I am running some ideas through my head.

These are my temps though which seem to be pretty good. I am on cruise control on the freeway at 70mph..its about 65-70 degrees out. This is the first time I have monitored them and it happened to be at night and a little cooler out. The max the EOT got was about 202 and the max ECT was about 198.

Weird thing is that when I am on the residential streets rather than the freeway,stop and go, the temps seem to spread a little further apart. The most they will spread is 10-11 degrees but usually close the spread pretty quick. They just seem to fluctuate more in stop and go. Is this normal?
