EOT- Engine Oil Temp. ECT- Engine Coolant Temp.

There's a article on abbreviations somewhere on this site.

Its usefull to tell you when you oil cooler is clogging, and getting ready to take you EGR cooler out, then your HG's

You need to monitor them to tell you if your oil cooler is getting clogged up. If the oil is more than 15* hotter than the coolant when the truck is fully warmed up and cruising at 65mph your oil cooler is clogged and needs replacing. Failure to do so at this point lead to ruptured egr coolers and blown head gaskets or worse. It isn't just important, it is critically important.

Ok, it's constantly hot here. My dad borrowed my truck this past weekend to tow our 5000lb camper. Cruised at 70mph, he got like 8mpg in 90deg weather. Boost was 15-20. Egts 900-1000. Ran just fine he said.

The oil and coolant are going to be constantly hot here where I live, so idk how to keep it cool other than stopping alot to let the truck cool off

Hot as in over 200*? 8 mpg doesn't sound right either. I get about 11mpg towing 7k through the Rockies here

He towed it to Dallas. All with head wind. I figure he get 10-10.5.
And all with the mods in my sig but I changed to tune to dp tuners 80hp Eco tune

But idk what the eot and ect stuff was. Never focused on that. When I was last on here, it said egts are what to focus on.

EGT's are also VERY important, but to save headaches and money, the EOT and ECT should also be monitored

To me, sounds like this ect and eot is really used for truck that tow alot of heavy weight. Most I'll ever tow is like 6000-7000lbs.

Actually, from what I've read and what I've interpreted on here is that you want to check the different between your engine coolant temp vs engine oil temp with the truck UNLOADED and NOT pulling anything on the highway at a steady 65mph when the truck coolant is up to operating temp - 190°F. Wow that was a long sentence. It's more to see how much restriction is in your coolant side of your oil cooler. I just replaced my cooler that HAD a 48°F difference between the two. I took an hour road trip yesterday and the maximum difference I got was 4°F (according to my Edge Insight CTS). Having it loaded with a trailer might not give you an accurate diagnosis of your difference between temps. Someone please correct me if I am wrong.
