Care and feeding questions: (1991 E-350 7.3L Diesel, non-turbo)
1. If I pull into a McD's and run in to grab lunch to go, should I leave it running?
2. Pulled the air filter out (PITA) and discovered that the dealership changed it already. But I noticed the intake that the filter can sits on (throttle body?) is very oily. Should I clean that? If so, what should I use?
3. Fuel filter is impossible to get at. Partially because of the extra wire harnesses for all the ambulance stuff. Should that filter come off with my fingers, or should I need a strap wrench? Also, when reinstalling the filter, should I use a strap wrench to put it back on, or spin it on like an oil filter?
4. Belts are LOOSE and there's no good way to tighten them. There's a pump on both sides of the engine. I assume one is power steering, what's the other? Fuel pump? And which one is on the driver's side? Is there a trick to tightening the belt for the driver's side pump?
5. Not quite a diesel question, but: I haven't worked on a truck like this before. Can I replace the shocks with it sitting on the suspension, or do I need the suspension to be at full droop?
Thanks again.
