Okay i cleaned my cooling system with the cummins restore plus because my ECT and my EOT were running 22* apart on a hard pull with the RV and they were running 11* apart on an extended pull truck only.
The results are !!! running truck alone the EOT and ECT are 2-4* apart and pulling the rv up 6% grade for 3 miles in 75* ambient temperature The EOT and ECT are running 10-13* apart.
In my opinion the cleaning was worth the $28.00
I am still out of spec on the hardest of pulls but running down the highway at 70 mph my EOT and ECT are running 6-8* apart so i am happy.
I might do one more cleaning just do get it back to factory but for now i am happy.

Job well done i hope you went beck with ELC coolant CAT EC-1 Rated coolant because the Ford Gold cxxp is just it can't take the heat.

HDJEFF, I buy the Restore Plus from the local Cummins dealer its a stock item, $27.00 for a gallon which will clean a 10 gallon system.
Regarding 2 stroker, after cleaning and flushing i do a final flush with distilled water .84$ a gallon at walmart, this leaves only distilled water if i missing anything, since i dont pull the plug behind the starter there is probably 2 quarts of distilled water left in the block. then i put 1 gallon of Caterpillar undiluted coolant, then i fill the rest with the Caterpillar diluted coolant, this stuff is suppossed to be good for 300K

where can you get this restore stuff at? thanks
Here is a little reading to get a background for WHY you need to ditch the Ford Gold Cxxp coolant. Just remember you need gauges to tell your temps and if you do a flush the best way remove the t/stat replace the houseing place cardboard in front of radiator because the Restore products must get to 185-190* to work drive for 1hr pull cardboard just before you get back just remember this may cause you to have cooler problems if your temps are high to start if so it is only a matter of time before they will need to be replaced so just plan ahead. When i did mine i had 30k on the motor and the first drain came out like White Honey Slim i used 48 gallons of distilled water 5 flushes Restore and 6 flushes Restore+ Total time 12.5hrs onces you start you CAN NOT STOP so it is a full day. Things needed
48-50 gallons distilled water
1 gallon Restore--1 gallon Restore+ use only 3/4 gallon each VC-9 Ford same as Restore+ just more MONEY
New t/stat and o-ring here Tousley Ford Parts Depot
4 Gallons ELC coolant use ONLY 3 1/2 gallons Concentrate to get the right mix in the end. I used Delo at $14.57 a gallon but any coolant that is CAT EC1-Rated like Fleetrite--Fleetguard-Cat or if you have a Napa close by get this Valvoline.com > Products > Antifreeze Radiator Products > Antifreeze > Zerex® Extended Life Antifreeze / Coolant
OK i will stop the rambling and get with the program.:doh:

This is very important information check link at bottom

Can't explain away Ford's logic. International uses Fleetrite ELC. Think about it. Whats is another silicate? Sand immediately come to mind. What is sand? It's an abrasive. Besides that it turns to a gell from the heat as it goes through the egr cooler trying to carry off the heat from high egt's resulting in the sludge that clogs the oil cooler. There is a substanial body of evidence supporting this.

Not having silicates is a positive thing. It has no adverse affects. ELC coolant is good for 300k miles without any additives and extendable to 600k with an additive pack at 300k. The new Delo ELC is good for 750k miles or 8 years extendable to 1 million miles.

I think it pretty much speaks for itself.

I'm on a campaign man. That Gold cxxp is killing our trucks and people need to know. It is the cause of the biggest problems we have with the 6.0 and the bad reputation the 6.0 has. And it is pretty cheap and easy to eliminate. People should know this. So yeah, I'm beating that drum. The other drum is the need to monitor ECT and EOT before you blow your egr cooler and head gaskets.

I just did a flush with Fleetrite Restore, VC9, lots of flushing, installed a coolant filter, and switched to ELC. Im curious to see what my coolant filter will look like after the first 500 miles, I know there is still most likely some cxxp in there still as I still have the stock EGR and oil cooler at 34k miles but I doubt there will be anywhere the abount that we see out of most of the posts with opened up coolant filters.

I recently installed the DieselSite.com coolant filter kit on my 2006 6.0. The kit came complete with everything you need and also came with the new billet aluminum filter head, looks really sharp.

PGreenSVT, dude you need to change your screen name to "ELC FOR LIFE!"

But I agree I just switched to ELC also, either way it cant be any worse than the gold, for those of you that have doubts just scrape the bottom of your degas bottle, thats the same cxxp thats clogging your oil cooler. When I did my flush I pulled my degas bottle and scrubbed it with a bottle brush, that cxxp is like glue.

--------------------------------------------------------------------------------

Here is the deal with the 6.0. Any good tuner (person writing your tunes) is not going to give you a tune that is going to tear up your truck. There are trucks all over the place running 400-420 rwhp with 750-800 rwtq all day long without problems.

Yes the 6.0 is known to blow head gaskets. This is why it happens. The Ford Gold coolant contains silicates. The silicates are not able to handle high EGT's generated by a good load or relatively high boost when run through the EGR cooler. They break down into a jell like sludge and fall out of suspension. This crud gets caught up in the tiny coolant passageways of the oil cooler. As the cooler clogs up it restricts coolant flow to the egr cooler. Now the egr cooler doesn't have enough coolant to carry off the heat generated by high EGT's. The limited amount of coolant in the egr cooler flash boils causing high pressure in the cooling system and the truck pukes coolant from the degas bottle due to the pressure. (it has to go somewhere)
Your uninformed Powerstroke owner is not monitoring his coolant temps and oil temps so he doesn't know whats going on and he keeps driving it this way. The problem get worse, the pressure causes the egr cooler to rupture. Now the egr cooler is leaking coolant into the intake manifold which then runs into the cylinders. Again the high combustion temps cause the coolant to vaporize. This causes unacceptably high cylinder pressure, the TTY head bolts stretch due to the additional pressure and there go your head gaskets.

Ok now you know the problem. Here's the cure. Get a good engine monitoring solution like the Edge Insight so that you can monitor your ECT and EOT. If those temps get more than 15* apart at normal cruising when at normal operating temperature your oil cooler is clogging up. Rebuild it now to prevent all that down stream damage from occurring. Flush that Ford Gold coolant cxxp out of your engine with a couple bottles of Restore. This is made specifically to clean out that silicate residue. Now refill it with a silicate free Cat EC-1 rated ELC coolant. This removes the silicates that clog the oil cooler from the equation. If you live in an area where you don't have smog inspections delete the egr system. If you can't delete it replace the egr cooler with the cooler manufactured by Bulletproof Diesel. This is vastly superior to the Ford oem egr cooler and it will not fail on you. If you find that you need to replace head gaskets replace the TTY head bolts with ARP studs and use black onyx (Victor Reinz) head gaskets. If you have to replace the egr cooler always replace the oil cooler. That is the source of the problem.

Now that you have addressed the common problems that scare the hell out of people, get an SCT tuner (i like the X3) and install some custom tunes and drive the heck out of it. DO NOT baby it. The Powerstroke hates this and will rebel with turbo issues.

Turbo issues are also common repair points with the 6.0. People like to complain that it's because the VGT turbos are pieces of junk. This is not so. The VGT vanes in the turbo need to be exercised regularly. This means making them go through there full range of motion. So put your foot in it regularly and let is see some full boost runs. That will keep your VGT vanes from getting all sooted up and freezing up because of the soot. Again, that is what happens when you baby it. Put you foot in it and you will have less problems. Lay out of it and try to milk it for mileage like you would a gasser and you're going to have turbo issues. Don't let it sit either. That is also the kiss of death to the turbo. The unison ring rusts up and again you have turbo problems. So now that you know you need to give your turbo a regular work out to keep it happy, give it a proper cool down as well. Just whipping into your parking place and shutting it down will lead to coking the bearings and again major turbo issues. Running a good synthetic oil will help here immensely because it handles heat so much better and resists coking. But always let your turbo have time to cool down. This is one of the reasons you need a Pyrometer (EGT gauge), Let the EGT come down to 350* before shutting your truck off. This only takes a couple of minutes, especially if you take it easy on it for the last couple minutes of your trip. If this is too much hassle for you get a turbo timer that will automatically delay shutdown when you turn off the key to allow the turbo to cool down.

Injectors. Fords injection system HEUI fires the injectors with High Pressure Oil, to the tune of 4,000psi at Wide Open Throttle. Maintenance is critical here so you can not let your oil maintenance slide like you can on a gasser. It will kill your injectors. The injectors also are known to suffer from something that we call stiction. That is when the oil side spool valve of the injects hangs up or sticks when cold until the truck warms up. I believe this is caused by varnish buildup that is common to dino oils, especially those containing paraffin. Using a good synthetic oil will take care of that because it actually cleans the engine as it lubricates. If you do find yourself with some injector stiction add a couple of bottles of Rev-X to your oil. It has cleared up 99.9% of the trucks it has been used on. 2 bottles run around $70. A new injector is about $250-$290. Be anal about keeping your oil clean and fresh and changing your fuel filters regularly. The other thing that kills injectors is low fuel pressure. The fuel pressure needs to stay above 45psi at all times and is typically set around 52 psi from the factory. Well the Factory fuel pressure regulator spring is weak and looses it's tension over time and can't maintain adequate fuel pressure. There is an updated rebuild kit that uses a better, stronger spring. Installing this spring will bring your fuel pressure up to about 62 psi and solve that. Get a fuel pressure gauge. It's important.

So that covers the frequent complaints with the 6.0. They are all well known at this point as are the solutions. Does it suck we have to fix Ford's blunders? Heck yes it does. But again we know how and once done you will have a very reliable robust truck that is well worth the effort. So address the issues as you can and enjoy your truck. It is a dynamite vehicle. I love mine.

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 or you can just order the t/stat and use the old houseing but you need a new o-ring

Here is the Restore Product from Cummins dealer

Here is a good post and on page 3 they used QuickOilDrainValve.com - the best way to change oil because you have to drain the block about 15 times:eek:
