I recently inherited a 3500 HD from my father who passed away. Only has 5k miles. Rarely used it the last few years, if at all, and as a result I’m now having a hard time getting her up and running normally.
Long story short, she powers on fine, but I’m stuck with an emissions warning and reduced engine power warning.
Things I have done so far:
- The diesel exhaust fluid was empty so I replaced
- Added Diesel Kleene + Bio Kleene and topped off the tank with fresh diesel (was 3/8ths full before)
I’m in the process of replacing the fuel filter as I’m guessing it’s completely sludged up. However, he had the underside rust proofed and I’m having a hard time with the cap. Tried the standard 36mm and wouldn’t fit around. Need to grab a 37/38mm and try next. Hoping I can get her to loosen up with those otherwise I’m guessing I’ll need to just bring it in to a pro to use some fancy gadgets to get her off. I also don’t want to break the whole fuel filter housing unit dicking around with it.
Anyways, my goal was to get the fuel filter replaced and hopefully that allows me to drive faster than 40mph from the reduced power warning. I then plan to take her on the highway and get the engine hot enough to hopefully kill off any soot that’s causing the emissions warning.
Does this seem like a reasonable plan or should ai just get it towed to a solid service shop and save myself the headache?
Appreciate the wisdom.
