We have a Mobile Shredding truck that is a 2009 International Durastar box truck with MaxxForce DT engine. It has a 100hp shredder in it that runs off the pto. We bought this truck used and are learning of all the issues... First issue; the truck started to overheat while driving down the highway. My driver pulled over and let it cool, never got over 230. We replaced the radiator cap as soon as he got to next town. The truck was already scheduled for a transmission service so we had the shop test the fan clutch too which they stated was operating correctly. We have changed Coolant to Zerex heavy duty extended life formula "Diesel Ready". Now the driver has to pull over 2 or 3 times going up this same route. Second issue; Regeneration light indicates it needs regenerating atleast 2 times weekly. The darn thing will run the regeneration for 25-40 minutes and never overheats the engine ( operates between 170 - 200 degrees) and completes the cycle but seems to want to regenerate frequently. (the first 4 months we owned the truck it only indicated a parked regen. was needed 1 time) now it seems constant. Lastly, we changed the oil & filter since we did not have any history on last oil change. New oil is Delo Heavy Duty 400LE API CJ-4/SM 15w-40 and since the oil change the truck is now blowing black smoke/soot out the stack when taking off and/or when the shredder is running on the pto during higher rmp intervals. (shredder runs at 1700 rpms standard) Oh and the truck has 171,000 miles on it (we have put 3,500 miles since November) So I guess my question is...Any idea as to why it is suddenly smoking after the oil change? And, any help with this regeneration issue and overheating issue would be appreciated. Thanks guys...
