SSDiesel glowplugs

[David85]

For the record, I would still like to try any dual coil glow glow plug I can get my hands on, but I will do my best to kill it on a bench before it goes anywhere near my engine. By fluke I was able to find a 10.8V plug for the diesel ranger and it concept does work well. Heat up times are about twice as long, but those can be left on steady while the engine is still warming up with no harm to the engine or the plugs. I haven't tried leaving them on all day while driving, but the point is they burn like a light bulb instead of burning out after 20 seconds. From what I've read of the bosch duratherm dual coil plugs, their output is actually higher than a stock glow plug. So while the heat up time is longer, they still put out more heat once they do reach full power. However, this is only what I've read so until I test one, I will still hold back from recommending anything other than the german made BERU plugs even if they are not self regulating.

i cant figure out how to use the volt meter i have so is there any other way to find out what ones are bad and what ones are good?

(i was talking about S&*^Y trucks and motors like mine)

450,000 miles, not one problem with Motorcraft/Beru glow plugs.
I think I will stay with the tried and true.

Just remember, if you have to pull a head or replace a piston, Motorcraft glow plugs would be a deal at 50 dollars each.

Thats all too true Dave.

yippy!!!
i tested my GP's today,and only found 1 bad.
replaced with a motorcraft/beru made in germany gp,and she starts WAY easier!(though its not real cold yet,she cold started in only a couple seconds.-was minutes before lol)
im a happy camper.

hey do you guys use never seize on your GP's when putting them in?
the old one sure turned out hard,so i put never seize on the threads.
this is a good idea right?

im almost on the road!
need a couple tires and getting my dump/flatbed this week (found a great deal!!) and then she will pass inspection.
yeah baby! can't wait to put this NOS (new old stock) '93 to work!

[Dodge/Cummins]

I have always put anti-sieze on mine.

i agree with ya 100% I bought a new set of motorcraft/ beru 40,000 miles. when the motor went i pulled them and gave em to my buddy who has a 94 idi and he is still using them.

I put copper anti-sieze on all my GP's.

Thanks to various problems, mine has an all new set of ZD-9's as of this year...probably just as well, the rear cylinders on both sides of the truck had Champions in them (which is odd, since all the rest were original ZD-9's).

Truck starts a lot better now, too bad my GP controller is completely on the fritz, have to use a pushbutton.

You really can't argue with experience, but there are those that make errors. Better to have something that is inherently safe. If BERU has a glow plug with dual coils to control temperature, I don't doubt that it would be a good one. If anyone has knowledge of such an item, I would be highly interested in getting some of them. In the mean time, I recommend the AC 12G or the Autolite 1109. I know these are temperature limiting and you can leave them on indefinitely with melting them down. You will kill your battery if your offspring accidently hits your switch and leaves them on. I can't help thinking that the bad impression people have of the OEM GPs comes from failed controllers that the engineers designed into the systems come with a Quick start system. I worked for AC Spark Plug in the lab that tested the GPs. I know of which I speak!

I remember you mentioning those ones in another discussion on this topic. Tried to source them through NAPA and another autoparts retailer and neither could get it in. One of them showed something like 3 units in the system way the heck over in ontario. Don't understand why they would be so hard to find.

Autolite is a cussword over here because their drop in replacements are so bad for these engines, but if the dual coil works as claimed I would consider using them.

I remember you also advised to dry test every glow plug before installing it in the engine. That was something I hadn't hear before then, but it makes sense.

[Marianna2003]

Sorry, I misstated myself. I meant to say that you can leave the AC 12G and the Autolite 1109 GPs on indefinitely WITHOUT melting them down. They are temperature limiting and will get red hot and stay that way as long as you have power on them. I bought a set of autolites for $10.00 a piece. Remember to heat each GP before you install it. That way if there is a problem, you won't have to fight with it to remove it. It will also prove that it is a temperature limiting type. Like I said before, cheap insurance and totally foolproof.

[Marianna2003]

OK I think i've found the holy grail for GPs. The military HUMVEES use a 6.2 GM diesel and guess what! The GPs will fit the 6.9/7.3. The terminals may be different, but the threads are the same and although ones thread is longer than the others it does not matter. BERU makes a GP for these that are said to be non swelling and temperature controlled. They are pricey but when you're talking about $800.00 to pull the heads to remove swollen GPs. It's cheap insurance. For BERUs: https://www.real4wd.com/B1WebTools/c...spx?PartNo=007 $21.15

Check out this website: Glow Plug - Military Humvee 6.5L I've emailed them regarding their GP_65MILHUM GPs. They even have the correct terminal! $68.5 + S&H.

how can we figure out a way to make these ones work?
BERU offers 3-phase glow plugs of the GE and GN type.
what are these suckers made for,that use the same thread pattern as our idi's?

are these ones here,that you mention for $68 each the same as those basically?-oops.correction.thats $68 for a set of 8! coooooool.

splicing new connectors is easy enough.
this is good stuff!

[Sycostang67]

I just replaced 2 bad GP's with MC/Beru's. I was a bit dismayed to find I was removing autolites. If the price hadn't doubled($5.89 to $14.99) I would have done all 8. At least the autolites came out nice and easy, no swelling. I will buy new GP's as often as I can until they are all MC/beru's though.

[tjc transport]

but why would you pay $21.95 each for the wrong aftermarket glow plug when you can buy the oem plug for $9.99??

[Marianna2003]

Sorry, I went off half cocked and told you that the GPs at "Glow Plug - Military Humvee 6.5L" were temoerature limiting. THEY ARE NOT TEMPERATURE LIMITING.
