Wrench light EOT/ECT

Driving the highway today going 60mph and my wrench light came on. I pulled over and hooked my scanner up and pulled up a p012f code. (EOT/ECT delta too high)? It was 76 out all day fyi. So i data logged the rest of my drive to see what I was getting. Going 60 I was getting ECT190/EOT210. I have read some threads and I am confused about what delta range is too high. The light has yet to come back on after I cleared the code. If my delta is wack, does that mean my oil cooler is shot? Still learning all I can about my psd. In town, I logged 200ECT/218EOT if that means anything as well. Thanks for any info you masterminds can throw at me. I DO have an egr delete.

Yes your oil cooler is toast need to do a coolant first then do the repairs or you will be doing it again. 15* is the max set by ford, you keep driving it you may blow the oil cooler then you will have a mess.
This should be in the driverside block drain to ease the pain in draining and getting burned.
QuickOilDrainValve.com - the best way to change oil
Here is another great cooling flush if you have to back flush.
http://home.comcast.net/~lyon.family...ush%20v1-0.pdf
Flushing and cleaning the 6.0

Restore is for cleaning out any silicate goo. VC-9 is for cleaning out iron and scale. Restore Plus is the same as VC-9 and cheaper.

To flush drain the coolant by removing the lower radiator hose from the radiator, and removing the drain plug from the driver side of the block. There is a drain plug on the passenger side also but you have to remove the starter to get to it. I don't bother with that one.
I also highly recommend you pull the thermostat out on your first drain and put the housing back without the thermostat. It only takes about 10 minutes and will save you 2.5 hrs or so in doing this whole procedure.

Ok now put the lower hose back on and the drain plug back in the block if you removed it. This is the procedure you will use each time to drain the system, except you will not touch the thermostat again until you're finished the whole procedure. Make sure that you set your heater to high while doing this to flush out the heater core as well.

Fill the cooling system with distilled water, start the truck and let the water circulate for 5 minutes. (if you did not remove the thermostat you must run the truck until the thermostat opens + 5 minutes to circulate. This takes 15 to 20 minutes each cycle and is why you should just remove the thermostat) Stop the engine. Drain the system and repeat the flush.

Now add at least 1/2 gallon of Restore and fill with distilled water. I used cardboard in front of the radiator because you have to get to 185* 190* for these products to work. Drive truck or run on high idle for 60-90 minutes just before you get back from your drive remove the cardboard this will help in the cool down same on the Restore+ flush. Drain and flush 3 or 4 times. or tell clean

Add 2qts VC-9 or 1/2gal of Restore Plus, top with distilled water, and drive the truck or run on high idle for 60-90 minutes. Now drain and flush until flush water comes out clear and clean. When you get clean flush water, flush 3 more times using distilled water while draining the block.

After your final distilled water drain it is time to put the thermostat back in take a funnel and dump the ELC coolant down the t/stat hole 3 1/2 gallons or till full to the top of the hole that way you have O air in the block, I recommend you install a new thermostat at this point 3C3Z-8575-AA Thermostat with housing come with new o-ring. They are only $30 or so and it is good maintenance procedure to do so and top off with distilled water. Drive the truck or let run for a while topping off with distilled water. Check the truck over the next few days and top up as required while any air left in the system works its way out useing the 1/2 gallon left over but fill with distilled water that will give you 1 gallon of mix fill ONLY to the add mark this is the new full cald mark. Remember the system hold 7 gallons of coolant by draining the driverside block drain and Radiator you remove adout 3 1/2 gallons of DISTILLED water that is why you only use 3 1/2 gallons of concentrate coolant this gives you a 50/50 mix.

Keep some 50/50 ELC on hand to use to top off the cooling system from here out and you are good to go.

new t/stat from Ford it should all come together (housing-t/stat-o-ring) in a box. The part number is RT-1169
My advice is to get some ph strips from Napa and check the ph level before add ELC coolant because you what a ph level of 7.0 if higher you must keep flushing to get to a neutral balance in the distilled water then you can add coolant, for me it was 6 flushes or 24 gallons of distilled water.

Here is the Restore Product from Cummins dealer

Restore+
Cooling system cleaner restore plus, CC2638, Fleetguard Cummins

wow thank you for all the help. Now does it still need the flush if the coolant was changed recently? Literally in February it got new heads because they were cracked and they didnt change the oil cooler obviously. So the coolants fresh but is it still a must to flush?

Why would they do new heads and not change out the oil cooler is there still warranty if not you need to do a flush and ditch the Ford Gold one of the reasons you had the problems and do you have a coolant filter to remove the casting sand the other problem put them together (plugged coolers)

I have an extended warranty which I have found out covers pretty much nothing lol. The truck just had all this work done a month ago. Idk why the cooler wasnt replaced. Warranty covered most of the previous work because it had only been 10 days since I bought it. They finally agreed to cover all but 2000 of it, now Im in a big battle with the better business burea and the bbb for the repayment from the truck lot who gave me written agreement they would cover anything not covered under warranty for this failure. Now this all happens and we will see what they say they can cover. This time I will make sure there is a flush done if it is covered and cat1 elc put in.

as far as coolant filters, who makes a good one. nothing fancy just something good and simple.
