Hello All,

I purchased a 2002 Ford F-250 SuperDuty with the 7.3 powerstroke about two weeks ago. Please bear with me as I am new to the diesel world. Anyway, I changed the serpentine belt, as well as, the idler pulley today on the truck (the belt has seen better days, and the idler pulley was in rough shape). I also have a single alternator. I followed the belt diagram, checked all the pulleys to make sure the belt was sitting properly on each pulley. The removal and replacement was not difficult, however I did lose a little bit of antifreeze from removing the radiator hose (temporarily) but I made sure to replenish what was lost. As i triple checked everything before start up, I went to start the truck and it cranks, but it poured some white smoke above the passenger side front tire. Truck failed to start. I have not had a problem starting the truck before I did this replacement.

The temperature outside is 47°F and there was some slight rain (if that matters).

Any help or ideas would be greatly appreciated!!

Thanks

The two sensors up front you might have disturbed are the CPS and the EBP. Check both to make sure the are intact and the connections are good.

This doesn't help much today but there is another radiator hose available that routes behind the belt. A very worthwhile investment.

Not really sure what the problem was. I went out this morning pulled the belt off the idler pulley to let tension off the belt. I checked all pulleys to make sure they were not seized. They were all good. I checked the CPS and EBP sensors, both were intact and connections looked good. Went to start up and it fired right up just like it did the last two weeks. So all is good! Maybe I got water somewhere it shouldn't be? I did change the belt with a slight drizzle outside.

Thank you all for your help!

Smoke coming out of that area might have been electrical. Possibly there was a short and the starter wasn't spinning fast enough for it to fire off, or there was too much voltage drop for the electronics to work. I would be checking things out there to be sure there isn't a problem.

May have been glow plug problem and exhaust leak somewhere after the turbo or the notoriously bad donut seals in the factory up-pipes from the manifolds to the turbo y-pipe inlet. By spinning motor over it prob spun the motor fast enough to move air from the radiator fan pushing that smoke down back of the motor....if that was it. Check for black soot on the alum that's on the firewall or around where the up-pipes mount to y-pipe and manifolds.
