Re: Ford F800 8.3 litre 250 hp
It is possible that the plate has been removed - if the cover/compartment has been replaced. It would be right in front of the injection pump (driver's side) on the curve of the timing compartment.
If it IS a 250HP or higher version, it SHOULD have the intake manifold heater. Basically looks like 2 big glow plugs mounted to the intake. If this truck IS as pristine as you say, there should be a sticker on the sun visor, and a light on the dash that says "wait to start".
If you don't have either of those, then you have 225hp or 210hp version. You should be able to keep it plugged in around the clock, but if you have a 'schedule' of sorts, then a timer will help keep the electric bill down. Ether can be used on the engines that do NOT have the intake manifold heater.
All that said.... we have a 275hp engine that starts like crap below 40 degrees, and I'll plug it in the night before I need to run it. It's done that since new, and only has 100k on it now. Last year we got a 225hp truck, and it will start anywhere, anytime, any temp. I have that one on a timer for a few hours before I leave. That's at 360k... I think you'll find the lower hp engines start easier in cold weather....
