What should all be done as far as maintenance goes for a '07 5.9 with 35,000km's on it? Sorry for such a lame question but I can't find my manual. All that's been done at this point is oil changes and the fuel filter once. Thanks in advance!

 

According to my maintenance schedule 36k km's is regular maintenance, oil, air and fuel is what I did. At 42k just a checkup. At 48K engine oil, tranny oil(auto) and filter, diff oil, air and fuel filter change. My is set for 12k km oil changes. I change the fuel filter at every oil change. hope that helps abit.

 

On my 05 i change the oil every 3,000 miles, i change the fuel filter every 6,000 - 9,000 depending how many times i fill up, i do a tranny flush every 25,000 and the diffs every 50,000...
