Which glow plugs would be OEM in my 2006 Jeep liberty?

I am guessing ceramic 7 volt? Maybe part number 05142577AA.

At what mileage should I change them out for steel?

Which glow plugs would I want to install when swapping them?

These maybe? http://www.etecno1.it/diesel-glow-plug- ... -1562.html

Etecno1 GX3123
diesel glow plug 7v double filament
This double filament 7V glow plug usually fits on european diesel engines, see cross references list and application below for more info. This is a fast heating glow plug, controlled by a fast starting control unit. It is produced in our factory. It's 100% tested on production line by automatic machines and lifespan tested according to oem protocols. It's made using steel sheated technology, it has been designed to replace original ceramic glow plugs. It's strong and long lasting.

This item is suitable to the following main competitors codes

05 and 06 KJ CRDs all had 7v ceramic glow plugs and what PN they were doesn't really matter as they are no longer in stock anywhere although with a lot of digging you might find some new or used but I would not recommend using them. When the ceramic glow plugs die, which I presume is more related to duty cycles (more cycles in colder climates) than mileage they tend to shed bits of the tips which can either pass out of the engine with no damage or take out valves/piston walls/turbo if you are unlucky. Frankly I replaced mine and stoutdogs as preventive maintenance.

Replacement options via IdParts, probably best source:
1. OEM 5v steel (4 glow plugs + controller + an ECU flash to change voltage supplied to the plugs which GDE can do or a dealer but it must be done before the new glow plugs are electrically connected = total parts cost including flash ca. $250 US) - downside is I've seen some reports of harder starting in very cold climates.
2. Etecno1 7v steel GX3123 (4 glow plugs drop in no controller change or ECU flash = total parts cost ca. $100) - downside is there appears to have been a production issue on some recent Etecno1 plugs resulting in early failure but as far as I know the bad ones have been replaced for no cost.

Replacing them is not technically challenging but:
1. do your self a favor and get Weeks101 (viewtopic.php?f=5&t=78238) intake elbow kit which gets a lot of useless junk off the engine and makes glow plug replacement a snap.
2. if you don't do #1 you MUST and as geordi and I know REALLY MUST pull the intake elbow fully off the engine when removing glow plug #3 and I'd recommend at least getting studs and nuts to reattach the intake elbow as access to the back bolts is a $^^$%(
other than that a slightly warm engine (block heater warm) helps loosen things up; proper size socket wrench and extension should make removal a breeze; be careful not to bang the ceramic tip on the way out (it's not easy to break but it is possible); if one of the tips is broken when it comes out do a comparison break on another tip (the new break will be nice and clean and if you are lucky the old break will be comparatively "dusty" indicating an old break and that the broken piece exited your engine with no harm). On reinstall some have reported that a bit of fuel line makes a handy "handle" to get the new glow plug started in each hole and a smige of anti-sieze might also be in order.

If you can see one of the glow plugs, it should have either a white or a red band around it near the outside tip. If white, you still have the original 7v, if red, they're 5v. You can also cross reference the part number on the control module. Double check my info though, i'm quoting from memory.

The glow plugs came off the shelf from the dealership near Pat when he replaced my engine with a new crate engine.

I am assuming they are ceramics. I always use Kopr Kote on glow plugs and everything else subject to heat or electricity that I do not have to worry about current following the copper.

What type of longevity might I expect? I want to be sure to get them out before they could cause an issue.

But I do not want to do work to prematurely. Don't have time and money for that. 6 months? A year? Longer? Immediately?

They may last a year or less, or they may last 8+ years. I've had both extremes. Personally, I wouldn't proactively remove them unless I was doing some other work that made swapping them out completely risk free e.g. a head removal. They're a bit like light bulbs, you can never predict when they're going to blow.

What would the risks be in pro-actively changing the glow plugs out?

There are zero risks associated with replacing them proactively other than the one I noted about the intake elbow. That said based on your comments about when you got them and the comments of Mike92104 I think it's important that you determine what type of glow plugs you have. If they came from a dealer then they are either 7v ceramic or 5v metal OEM plugs (there was a point in time when DCJ dumped the stock of 7v ceramics). I don't know for sure about the band color test but I do know that #1 is easy to remove if you need to do a visual test of the end.

If they are OEM 7v ceramics IMHO death is more based on numbers of duty cycles than anything else (more cycles in colder areas than warm areas) and if you get a glow plug code with ceramic plugs I'd replace them immediately.

If they are OEM 5v ones then run them until they die but when they do you will have to use 5v OEM metal replacements unless you do an ECU reflash (GDE can handle) to revert back to 7v plugs to use the Etecno ones.

It occurs to me that if a dealer did the work then the invoice should have the PN of the plugs installed. If so determining what they installed is easy.

The risk is having one snap off in the head as you try to unscrew it. Now you have to pull the head to get the pieces out.

The glow plugs were one of the things that the dealership supplied, that were supposed to come with the new engine. I got royally hosed on that end of the whole deal They sent me a list of what was supposed to come with the new engine and what We would have to supply or reuse.

Basically, we got a long block and the dealership said we could return it or be stuck. I had already ordered stuff that I would not have ordered if the engine was a put together and not a new engine. So I had a bunch of money invested on the basis that I was getting a new engine with everything that was listed on the sheet that they said came with what I bought. it caused a big loss in time - we had to order more parts before Pat could proceed with the engine. Then he kept running into stuff that the first dealership that worked on the Jeep broke or lost. Some of which was supposed top be on the engine we bought.

I have the weeks elbow installed. Pat installed it in record time. Without touching the fuel filter. Messing with the fuel filter alone would have taken me more time than it took Pat to have the elbow in and done. The glow plugs were not ordered. It was something they happened to have on the shelf. Since they just gave them to us as part of the engine package we never got a receipt.

Seems better to pick your time, than have one drop off in the engine when you do not know it. Since 8 months was the earliest I have heard of a glow plug self destructing. I will leave them in maybe another 6 months or maybe just til the next oil change.

It doesn't have to be removed. The white or red band is one the electrical connector side.

Click on the picture on this page:
http://www.idparts.com/catalog/product_ ... ts_id=2858
and you can clearly see the red band on the glow plug. If red, it's 5V, if there's a white band in the same spot, it's a factory 7V with the ceramic tip.

Thanks

I will probably pull at least one anyway just to verify how the anti-seez is holding up. Recoat and re-install. I do it about every 2 years on my 6.5's . It doesn't take near as much time or effort as having to deal with one stuck glow plug.

I also plug the block heater in whenever working on block related stuff. You get bolts tighter in a warm block and they come out of a warm block much easier.

I've had oil filter adapters that would not budge on a cold block, come out easy once the block was warmed up

I was just going through a box of stuff left over from the engine install 30,000 miles ago.

Would be a lot more miles if this thing had any dependability at all.

I found 4 - 7 volt glow plugs with the white band so I am guessing those are ceramic and came out of the OEM Engine. I know there are 5 Volt steel glow lugs in the Jeep now.

I have the Green Eco tune.

How do I find out if my Jeep was flashed for the 5 volt glow plugs?

I am Assuming Pat installed whatever he was given. The last time I asked him, He did not remember much about the glow plugs.

I don't think either of us knew anything about the different voltages at the time.

What's my next move now that I found these glow plugs?

I have had the Jeep to the dealership a couple of times since. Is this something they would have checked?

This will be next after I get the transmission fixed

Was there any damage to be done by running the 5 Volt glow plugs if it was not reflashed?

I thought I read about somebody running like that for a long time
