I just bought a 2003 CTD 2500 4x4 with 129,000 miles on it from the son of the original owner. It has new injectors and lift pump and a rebuilt auto transmission with a billet torque converter as well as new brakes. Also has EGT, transmission temp and boost gauge and an exhaust brake. He didn't know much else about the truck as far as when the last maintenance was done on it so I plan on resetting everything by doing them. Oil and filter, fuel filter, air filter, differential fluid, transfer case fluid, antifreeze/thermostat/hoses and serpentine belt. I've owned an 03 and a 04.5 previously so I'm not new to the truck but I have a few questions with regards to a few things.
Fuel filters: Have they come out with a drop in fuel filter that filters down to 2 microns or am I looking at adding something like the GDP kit? I've read Fleetguard FF5814 and Baldwin PF7977 both filter down below 5 micron but not sure if they'd suffice to ensure clean fuel doesn't eat up the injectors.
Whats the longevity on water pumps? Should I change when I do the antifreeze? Not sure if it's ever been changed.
The only thing that doesn't work in the truck is the temp probe, it's gives me a temp that's cold enough to store the Pfizer vaccine. Living in the mountains in Oregon it's nice to know when the temp is close to freezing for slick road conditions. Is there a probe under the hood somewhere I can check/replace?
With the transmission, when it shifts into overdrive it's a very firm shift when you are accelerating, is there anyway to tame this down a bit? I assume it's in the valve body setup.
Anything else you'd do with a truck like this if it was yours?
