Well I've got a 99 F350 with the same engine and had to do lots of cranking to get it going. Took it to the local expert and they replaced 4 glow plugs (3 on one side and 1 on the other). Started and ran great afterward. Just a note here -- if you are paying someone to do the work -- have all the glow plugs replaced while they have the valve covers off. They are not that expensive compared to the labor to replace one.

I suppose you could but I didn't see it done so can't say how difficult is was. I had bought 2 glow plugs from NAPA when I took it in and they installed 2 and used my 2 also. Good guys -- most repair shops wouldn't use parts that you bought.

So your glow plugs are in the intake manifold! on top of the motor much like spark plugs!!!! Jst went through this with my 93 7.3L! did them myself took 35 - 40 min! Go down to your local parts store and by them!!!!! Just make sure that when you pull them out do it gently you dont want to break the plug off in the intake if so you are in for some work and money!!!!! But do do them all at once if all the other starting and charging system is new might as well go all new for the glow plugs as well! Hope this helps!

I read some where that on this system if one is burned out none of them work. I have the same problem with mine. In a pinch you can manually cross the relay. I've replace six so far. The other ones under the turbo I havn't changed yet. I hope when I change the other two they work like they should. For now I just keep it plugged in. Good luck!

super easy to change like bend over said be careful not to break any pulling out. you can check them by removing connector on top of plug and with a test light hook to 12 volts and place on plug if it lights up its good if it doesnt its bad. i also like to put anti seize or white lithium on plugs when installing to keep from seizing for next time good luck
