eot/ect delta with 1300-1500 lbs in bed

[neffco]

My delta has been up to 30 but the ect is sitting between 176-184 most of the time. Pulling hills the highest eot I;ve seen is 214. eot is usualy at 202 -204 in the flats with ect at 176-182, outside air 24. I tryed blocking air flow on the radiator but dont see a differance. I'm a bit worried I do 1200m + a week with my welder and tools. I cant really empty the truck right now to test empty.

Pull that oil cooler soon and replace it. You're gonna cause the EGR cooler to blow and loose your headgaskets otherwise. Your EOT is high. Do you have any puking as of yet?

[neffco]

no puking as of yet. no sweet white smoke either

[drunk on diesel]

do 6.0's run cold or something? 176-184 water temp? seems low.

204* oil temp is not too high

214 eot was uphill with a headwind

I'd try replacing the thermostat first. My truck runs at 188* empty no matter what the outside temp is

I'm going to try and get a t-stat and do a flush at some point this week. I work 100 hr a week so I dont have much time and getting covered in coolant at night in 15 degree weather doesent sound very fun after work.

[neffco]

I know I need to do the cooler soon but was hoping not for another 7500 miles so. judging by others eot s I'm not far off if I could get ects up to acceptable level. any 24h 6.0 mechanics in western nd that arent booked three weeks out? someone could make a good chunk of coin up here.

The max i have seen is ECT 218* EOT 228* in 90+* going up a 6% grade about 6 miles long pulling my 14k 5er and the fan sounds like a jet plane, my normal temps run ECT 194-196* EOT 200* and pulling on flat ground add 10* to each. The stock Ford t/stat starts to open at 192.2* and is fully open at 219.2*.

Here is the flush i did used 48 gallons of distilled water 1/2 gallon Restore then 1/2 gallon Restore+ 1/4 tank of fuel and 12.5hrs of my time but my system is clean.

This should help you understand the reason to ditch the Gold junk it can't take the heat. Gauges are a must to do this need to know EOT-ECT
Replaced oil cooler still difference in temps

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. I recommend you install a new thermostat at this point. They are only $20 or so and it is good maintenance procedure to do so. Fill with 3.5 or 4 gals of ELC concentrated coolant 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.

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
