Tip & How-To about Ford F-350
Hi, if you have any problems starting any type of diesel engine then this is a very good indication that one or more of the glow plugs need replacing, to get you home you can try turning the ignition on and then wait for the glow plug light to go off then instead of trying to start the engine turn it off then back on again, doing this usually gets it started just to get you home but this wont allways work.
Its best you replace glow plugs sooner rather than later as it could leave you stuck without a vehicle.
To change the glow plugs follow these quick instructions.
1. Look where the injectors go into the cylinder head then just under these you will see a smaller plug that will have a fixed wire this wire will be running from glow plug to glow plug this wire is held onto the glow plug by an 8m nut undo this nut on top of all the glow plugs, once undone you will notice that one of the glow plugs has two wires the other wire is the wire that carries the power to all the glow plugs so just remember witch glow plug this goes to.
2. now once you have removed the connecting power wire remember witch way it runs so as to get it back on the right way round it doesnt matter to much but might be a bit tight if you put it on the wrong way round.
3. Now how to undo and remove the glow plugs: To remove you will need a deep 10m socket place this over the top of the glow plug push down to ensure tight fit then undo this glow plug will then pull out (make sure their is no muck around the glow plug that can fall inside the cylinder so just check)
once you have it out its best you replace all the glow plugs as once one goes you will find that the others wont be to far behind.
4. Fitting new glow plugs. When your fitting the new glow plugs put them into their hole and gently screw in by hand to make sure you dont cross thread the thread as this can be a nightmare to put right. tighten the glow plugs in as much as you can by hand then nip them up using 10m socket and extension bar now dont over tighten them as this will damage the thread just tighten up till just after they stop then you should find they are ok.
Refit the wire loom on top of all the glow plugs remembering to fit the main power wire to the first plug make sure you tighten the nuts up properly on top holding the wire in place.
Once you have done this you are now ready to start your vehicle you should now find it starts with no problems.
If you still have problems starting you need to now start looking at things like the diesel filter or even the diesel pump, ill explain about these in my next post ok
