Well the first 22,000 km's burned 3 litres of coolant. I put dye in the coolant and they couldn't find a external leak. Had trouble, couldn't get ahead of a loaded welding truck from a intersection. :{ The next 32,000km's burned another 3+ litres of coolant. Had to plan any passing of loaded vehicles. Since have added about 6 or 8 litres of coolant. Exhaust has rusted through. One time when I had the truck loaded at 11,400 lbs ( yes I went over the scales) I got 30 miles to the Imperial gal. Chrysler and Cummins has let me down ever since I got this truck new with not being able to identify the symptoms of the engine. High mileage, lack of engine heating,( said I needed a viscous fan when the thermostat wasn't opening) engine bucking at 1100 to 1275 , 1800 and 2200 RPM. Just wasn't able to find an intelligient mechanic or service advisor.
Since July it has been putting out 3 to 5 lbs boost going down the hiway. With a top boost of 20 lbs, Should have more with the PNP in. This is about half of what all of you guys get alll the time. ( Boy I envy you lot. ) Of the 50 diesels that I have operated this is the worst diesel by far.
