The EGR cooler gets both ends opened up and a air hose goes in and a cloud of soot blows out across the back lot... Then if you can clean it enough, you force a re gen to burn off the rest... We had "Truck drivers" and they knew everything, so they would hit the button not letting the truck re gen. Until it finally shut down... You dont want to do that very many times.....
After working on trucks for 40 years I'm staying with gas... Its way cheaper in the long run and a lot less headaches.. If you have one, remember to keep trading, you dont want to be the one that has to pay to replace all the crap when it wears out...
