2005 Detroit Series 60

heavy black smoke and poor MPG... visit workshop for futher diagnostics becouse you may have bad EGR, bad VGT, bad boost lines ore bad intercooler... ore may be leaking injectors. I know how to check all this stuff with DDDL and hands and eyes. Loosing coolant..... what about EGR cooler? Any leak from head gasket, coolant overflow reservour, any bubbles in coolant? Wight smoke at idle and smell of coolant from exaust (hah, how easy to check EU truck with Weed Burner exaust!!!).

Ok. If you are the real DIYer I can help you.. if not... - drive to workshop!

 

Hi Pablo ive got a similar problem on an 06 columbia with 14L Detroit its done 760000miles lots of black smoke, spluttering and like a loud backfire and a few jerks on acceleration, loss of power and bad mpgs 4.9. I was told to change egr valve which i did but stil the same! Checked my intercooler which had no leaks, changed vpod still same! Changed egr cooler and turbo but still same!Changed all sensors but stil same! Last trip it started losing coolant and some traces of coolant in oil ! Changed injector seals but still the same! What do you think it could be? Theres no active codes showing up on my nexiq thanx HUGE

 

boy this sounds just like my truck

 

Holes in your cylinder liners from not keeping your coolant additives up to standard.(SCA's).

 

Hi Dave thanx for info. I first have to get columbia home its about 1600 miles away!
Once its here is only when I can try and find cause of coolant loss!

 

code 44 is suppose to be protection codes which will give the red check engine light

44 105 - 0 Intake Manifold Temperature High
44 110 - 0 Coolant Temperature High
44 172 - 0 Air Inlet Temperature High​

44 175 - 0 Oil Temperature High

code 39 is a "logic" code

39 - 146 2 EGR Leak - Boost Power
39 - 146 12 EGR Leak - Boost Jake
39 - 146 7 EGR Valve Not Responding
39 - 147 2 VNT Vanes Not Responding - Boost Power
39 - 147 11 VNT Vanes at Max - Jake
39 - 147 12 VNT Vanes Not Responding - Boost Jake
39 - 147 14 EGR Flow too Low​

39 - 147 7 VNT Vanes Not Responding - EGR

really we used to swap ECM from 12.7, turbo from 12.7 and no VGT, no EGR

 

Hi Pablo would you know where I can get info on how to uprate horsepower and torque to Max without changing turbo,injectors on series 60 12.7 and 14.7 with egrs
using a nexiq prolink? Thanx
