My 6.0 currently has 78000 miles on it. I know the EGR cooler failure is coming at some point. Should I replace it and set it all back to how the factory had it or should I just go ahead and delete it??

What should I plan to buy for this truck?? Heck what should I plan to do about that problem that will come at some point.

 

i am also wondering the same, on my 03, i wanted to put an edge chip on it, but after doing research, the people that chipped their 6.0's, said that they worked out great, but the next day where in the shop because of the egr, so should i just delete the egr, or just block it. and if so, what and where do recommend getting the delete kit?
thanks

 

03s have a better EGR cooler, so may consider not deleting it.

 

There are many knowledgeable guys on here that will most likely not chime in on your question.
The bigger answer is to monitor your engine with accurate gauges. Monitor your EGT, ECT, EOT, and Fuel pressure as a minimum.
1. If they say yes, then they are recommending that you delete an EPA required device.
2. If they say yes, then you could potentially running you 6.0 too hot (IMO).
I have read many posts on here about this question and in the end, no answer was definitive. I believe the EGR provides an amount of security though the PCM preventing the engine from cooking itself under heavy load. If you have EGT monitoring you can get the maximum power with a margin of safety without an EGR. The question remains …. Does the “STOCK” PCM and FICM change the fuel strategy when it detects the EGR has been removed. This is why I have left my EGR connected and monitor my EGT’s.
I am NO expert and am open to more knowledge!!!
The decision is yours.

 

I have a buddy with an 03. He has never had an EGR failure and he's over 200k now. On my 05, It had 2 before the delete.

 

Might want to give this link a read. Since you have an 05. Interesting testing cheezit is doing.

I honestly would recommend something other then the Edge chip on it. Those don't have the best record with 6.0s and they really don't have good "tuning" at all. Tuning is in quotes, because shift on the fly devices don't really tune the engine. They "fool" the engine. Does that really sound like a good idea to you?

As to the main question of what to do with the EGR system. Contrary to popular belief, you can have a reliable system that is still running as it should. You have to be more mindful of what's going on, how your driving it etc, but you can have a completely reliable system without having to delete or bypass it as long as your truck is stock or just has some slight tuning to it. Now 78k on an 03 isn't that many miles, but it may depend on how those miles are driven. The irony is that there are contradictions with the 6.0.

As was already mentioned, gauges will help you out the most. There are just too many people with EGR systems still running with no problems that makes me think it's one of those "delete or bypass only" types of scenerios.

 

I don't mean anything negative when I say this, but I hung out on the Mustang forums for years and it was alot more starightforward there. Not alot of debate going on like there is here(not neccesarily a bad thing). I am sure its because of the platform, but there it was about either solving a guys problem or gettin on a soapbox. From what I can tell so far the only things everyone can agree on here is get a coolant filter and get gauges. Until today and reading this thread I was ready to buy my EGR delete, Edge Monitor, coolant filter, VC9, Premium Gold, and distilled water and schedule a couple days of vacation. The problem with this egr thing is that there is tooo much info on the subject. I have been reading for three weeks and still don't know what to do.

 

The debate really stims from misinformation or a general lack of knowledge. Mustangs, relatively speaking, haven't really changed all that much. Not like the leaps and bounds that diesels have in the last decade. You also have other complications surrounding the 6.0 as well. The more info one has on this truck in particular, the better off they are.

I try to stay away from the stuff like, it's breaking the law or in the case of trying to get someone to quit a habit, it's bad for your health. In most instances, people just don't care. I try to argue it from a perspective that most people do care about and that's money. I'm not saying it's the end all be all, but it's a powerful motivator that's for sure.

It is far cheaper to change one's driving habits and add a coolant filter then it is to do a delete and/or bypass of the EGR system. Plus, you may or may not be looking at fines if you get caught. Don't think all emissions places don't know what to look for. Around here they do. Deleting/bypassing the EGR system for a stock/tuned truck is not a necessity. It just isn't. The one issue that the trucks might have a good chance of getting(although I never have) is a clogged oil cooler which caused the EGR cooler to fail. However, I would say that it's the oil cooler as a primary cause on that one, not the EGR system. Compound that with techs not fixing the root cause and you might have 2 or 3 EGR coolers replaced before the oil cooler is. Once the oil cooler is replaced, don't have any more issues, but people went through 2 or 3 EGR coolers in the process, so the EGR coolers must be crap....right? I don't think so.


You can never have enough information on a subject. The reason why people still buy Edge modules(and similiar) for the 6.0 trucks is due to the lack of knowledge for whatever reason that may be.

 

I agree with Tex 100%. The oil cooler has a tendancy to plug due to small cooling channels and sand and precipitates in the cooling system. In my opinion, I would replace the egr/oil coolers, flush with VC-9 and install a coolant filter system. Then fill with Premium gold or Zerex GO-5 at a 50/50 mix of distilled water. Keep in mind that the coolant filter is an excellant insurance policy but not a total guarantee of a possible future failure. Even with a deleted egr cooler there is no guarantee that the oil cooler will not plug again which is usually the root cause. If they do smog inspections in your area you will also have peace of mind come inspection day.

 

Like Tex said, the EGR delete has become a muddied issue due to expanded knowledge on the subject. Two years ago the delete was the answer. Now that the real issue with the oil cooler is widely known, the delete has become less popular with people who actually understand what is happening. If I was doing a 6.0 today, I would not do a egr delete that was visually detectable if I did one at all. The Edge Insight/fuel pressure gauge and any pertinent reliability mods for your particular model year. An example would be the STC fitting upgrade on an 05 and newer engine

Edit: I never want to race with 69CJ if he drives like he types. His advice is also golden

 

I didn't realize until today that actually the oil cooler could be the root cause of the egr cooler issues. Do you guys have a coolant flush process that is documented somewhere? I didn't notice anything in my visits to the tech folder.

 

well, what would you recommend other an edge ship?

 

Custom tuning has been the one type of tuning that has had the most success in the reliability department and also in ability to produce even more HP gains then what you could get from Edge, Bullydog, Banks etc.

You have several options. SCT(which has the most tuners(people) out there to get a wide variety of different tuning styles), PHP(which actually uses Edge devices as the platform, but they are custom tunes), and Spartan Diesel(they use the DashDAQ as the platform for their tunes).

I personally have experience with SCT and the Spartan devices. If you go the SCT route, I wouldn't go with the LiveWire as that is still a troublesome device. I would do the X3 and then get either an OBD-II monitor and get an analog Fuel PSI gauge or go all out with all analog gauges. The Spartan platform is what I use now and I like it a lot more the SCT, but it is also pricier as well.

While I have heard good things about PHP and their tuning, I have had no experience with them.

 

Here you go. All the information you will need. Have fun.
