changing glow plugs.

hammerdowndodge · **Posted:** Sat Dec 01, 2012 7:26 pm

My wife has around 130k mi. on the jeep and the glow plugs have never been changed to me knowledge. got it with 23k. How should i got about taking them out? With the engine cold or a little warm? What kit should i get? The one on ebay is the same one idi had but cheaper and free ship. Also as far as going to the dealer to get a reflash, what do i tell them when i want to do so ,and how soon after changing them do i need to get it flashed.

1st, you need a timing belt job ASAP if you haven't alreay done one.

My advise regarding Glow plugs is this, have the dealer do it..... If they break a plug and half of the broken plug is left in the head, it will be on their dime to dismatle the head to remove it. This has happened many times. They will also reflash the ECU.

Providing you didn't bring the vehicle in with a engine light on indicating a glow plug problem.

If you break it, then it's on your dime and the cost to remove the broken plug from inside the head will be over $1800 dollars to do the work or more if you need a Timing belt job.

Just my :2cents:

Read my experience under my crd saga thread. In brief, 2 broken glow tips caused minor cylinder damage, but possible damaged the turbo. While changing out, snapped #4 in the head due to carbon around the threads. Discovered major lifter wear when head was pulled.

I am not trying to scare you, just telling you about reality. There have been reports of broken tips wiping engines. I would get it done asap, as well as a timing belt if it hasn't been done. Where are you located and maybe we can refer you to someone.

Yes i have done the timing belt and items as listed in what to change while doing the t-belt. did it at 110k i think. i am good friends with the local dealer and they loaned me the tools to do the job. even had a teck. who had done a t-belt help me time it. There is no check engine light on. How much do you think it would cost to have them put in? located in south east NE.

For a second I thought you meant New England...thought we had another CRD member. If you go the factory route, about 200 in parts, 100 for flash of ECU, and a few hours labor...if it goes right.

We had one member who had to pay for head removal because they broke a GP. But that is much cheaper than a broke motor.

The other method is the Etecnos, but are only available shipped from Europe. No flash is necessary since they are 7 volts.

If you do it yourself, don't forget the intake gaskets. Removing the intake elbow is a must. If you experience any that seem stuck, stop and get professional help.

Me personally, I would order all parts from idparts.com (5v oem) and get the GDE ecotune and have it setup for 5v plugs.

YES THEY WILL.

And it's spelled GDE Tune, Green Diesel Engineering Tune ... I say.

Talk to Keith about how to proceed.

Do any of you really think that a dealership will accept responsibility if a ceramic plug tip breaks during the procedure? They'll blame it as a pre-existing condition or find some other excuse.

I've got 2 glow plug changes under my belt. They are not hard to do, just a little tedious on no. 3.

If you take it to the dealer, you could always get the service manager to confirm if a plug does break upon extraction that they would be responsible for the repairs.....although they may try and say it was already broke when they got in there if they break it.

So then how would you go about getting the factory glow plugs out of a engine with 130k mi.

I would start with Kroil. I would spray Kroil on the GPs for a week.

3 things-

-Kroil

-Find a real mechanic, not a dealer.

- My intention is to use a T handle to make sure that I am not imposing any eccentric loads on the GP when I remove it.

Did I mention the copious use of Kroil? Kroil is your friend; it loosens and lubes threads and helps prevent galling of dissimilar metals. Kroil the GP threads morning and evening for a week. There are no guarantees, but the odds are good that this will help a lot.

I'm going to agree with Bull on finding a mechanic and don't use the dealer. Find a reputable shop that has an experienced, dedicated diesel mechanic who has experience, at least, on TDIs, Mercedes, Sprinter Vans, and any vehicle that is foreign and extra sensitive. From my experience, the word Jeep on a sign, that's posted out in front of a building, with lots of Jeeps around, means nothing as it relates to the CRD. There are guys out there that are smart, and actually give a sh#t. Don't ever hand your Jeep over to anybody who is not like this.

Another thing to keep in mind: I just had my shop do the Etecnos. When they pulled out one of the ceramic GPs the threading came out with the plug, and the tech had to re-tap the housing. I definitely wouldn't want some Dealer Gomer doing something like that.

Best of luck with it.

It helps to have the engine warm and if you can cool the glow plug with a frozen socket that should also help a bit. Learned a new trick when that was posted. Make sure to use a deep well 10mm socket and do not side load it when backing out and it should come out ok. Put some anti seize on the threads of new glow plugs when installing. It will make the next removal much easier.

125k on mine, with no current glow plug issues and timing belt already done. Naturally I would not like the plugs to break when the engine is running, but if they "reliably" break on extraction, I would also not like to have to remove my head and re-do the timing.

What are the most common glow plug failure scenarios? Do the plugs simply break apart in use, with no warning? Or do they break only when failed and/or extracted carelessly?
