How do you change the glow plugs in a 99 F250 Super Duty?

On the drivers side:1) remove intercooler tube and air intake

tube 2) remove valve cover bolts 3) disconnect glow plug wires

(white) 4) Using 1/4" drive 10mm deep well socket 5) to more easily

remove the plugs use a piece of nylon hose (works well to reinstall

too). On passenger side the process is just about the same but I

found it to be quite a bit harder to work around the heater core;

one way to make things easier is to reach through the wheel well

with a box wrench; also don't even attempt this job without a long

extention and a knuckle for your wrench...Good luck!
