Need source recommendation for "life" guarantee EGR & oil cooler
Already have thread up about my problems but now need to find a source of SOLID REPLACEMENT parts for EGR and oil cooler that last longer than the OEM Ford parts I used last time. They failed after guarantee expired.

A couple of question might help you avoid a repeat of the problem.
Do you use the Ford gold coolant (the coolant installed at the factory and the only coolant Ford recommends for the 6.0)?
Have you read about this type of coolant having a tendency to gel when overheated?
Some causes of overheated coolant:
-Leaving Block heater on for extended times.
Do you use your block heater and how long do you leave it on?
I've heard the block heater can create local overheating, which can cause the ford gold coolant to gel. This gelled coolant collects in the narrow passages of the oil cooler, eventually clogging it. With the flow through the oil cooler reduced, the coolant in the EGR cooler doesn't have enough flow to prevent it from boiling. This causes the EGR cooler to rupture.
When you had the oil cooler and EGR cooler replaced, did they perform a cooling system flush?
One way to deal with gelling coolant is to flush the cooling system more often. Ford originally recommended replacing the coolant after 100,000 miles, however, more recently they have been recommending replacing it after 30-50,000 miles.
Replacing the coolant is not enough if it has begun to gel. At that point the system needs to be thoroughly flushed. There's a chemical that breaks down the gelled coolant and it's called Restore. This can be obtained at a Cummins Dealer for one....if you look around you can find it other places as well. There's another chemical that will break down Iron deposits and it's called Restore Plus as sold by Cummins, or you can buy this same chemical at a Ford dealer, but Ford calls it VC-9.
If you flush the cooling system with Restore first and then Restore plus, this will remove both gelled coolant and iron deposits which are both causes of clogging. How often you need to do it, depends on how hot your cooling system is getting. If you do a lot of towing in hot weather, or use your block heater a lot in the winter, you will likely need to flush it more often to keep the system free of gelled coolant.
You can also replace your EGR cooler with one from Bullet-proof diesel. This after-market EGR cooler is guaranteed not to burst, even if the coolant boils. It won't prevent the oil cooler from clogging, however, it won't be as likely to boil the coolant, since the coolant will flow through it's large passages easier. So, if you buy this EGR cooler, you also need to keep up with cooling system flushes. I do mine every 50,000 miles.

flush with vc-9, install bulletproof diesel brand egr cooler, ford oil cooler, coolant filter. DO NOT run it without installing the coolant filter after install.
be sure to flush it thoroughly before taking anything apart (flushing can take a whole day)
