7.3L Glow Plugs. See Details.

[slammed83mazda]

I have around 29 glow plugs for a 7.3L literally 29 of them. My father in law works at a dealer ship and asked if I needed any and on my old diesel I did but never got around to replacing them. So he told me don't buy any he has plenty.

From what he told me, when a truck would come in if it had 2 bad glow plugs. They would replace all 8 and keep the other 6. So this is how I got so many even though I only needed 8.

I cannot confirm the working order on these, but I can only take the man for his word.

I'm thinking $25 shipped for 8 of these.

If there is any way I can test these without the truck please let me know, I sold my diesel and these are just laying around.

Anyone anyone?

[the great white]

how much do these normally run?

[zilla68]

10-15 each for the zd-11 motorcraft ones, depending on where you buy them plus shipping or tax

There is a way to test them without the truck but I dont know exactly without searching for it.

battery charger,clip onto the nipple at the top of the plug,and clip onto the main body of the plug if it glow orange its good if not its junk they either work or there garbage. you can also use jumper cables and a battery.

I could use 8 working glowplugs. I believe you just check the ohms.

If anyone can confirm this working I will try it.

Don't want to fry these bad boys. Do I just clip a + onto it or what. Let me know.

Ohm them out.

A good glow plug will read btwn 0.8 - 1.2 ohms a weak glow plug will have much less resistance, and a completely dead one will have unlimited resistance through it because the electrode is internally burned out.

Yes. Alligator clip from the 12v positive to the top nipple. Put a negative on the plug body to ground out. Will glow red almost instantly. I've done this many times.
