Sure but that doesn't mean that they are exactly alike. They could have regional differences.
Example car commercials that say 'European model shown'. Or that every car at the wreckers that came out of California had different emission parts than what I needed.

Here is Etechno1's 11 volt glow plug for

JEEP LIBERTY/CHEROKEE(KJ) 2,8 CRD VM (11V GLOW PLUG) 2.8 4 110 12 11/02->01/06

http://www.etecno1.it/diesel-glow-plug- ... -p-10.html

Read what MrMopar wrote!
Have you not read they are using PWM on the glow plugs
What your saying about Car parts from California was right at one time. Also our CRD's were not allowed to be sold new in California and the other "me too" liberal states

Maybe it is just our colloquial differences but I really don't understand you.

MrMopar said-

Low voltage is any modulated voltage below battery ie. 5, 7 or 11 volt.
...

If you install 5 volt plugs you need a flash.

And yes I know that it is a PWM system.
I know how they work; I have designed PWM systems.

This is post at JeepKJ.com from retmil46 (we know him here too) . I am going to believe this is true until proven incorrect:


So, whosthedaddy07, you probably have an 11 volt system and have many choices for 11 volt metal plugs. You probably burned out the 7 volt plugs with over-voltage. There is no need to switch to 5 volt plugs; probably why your dealer has no information about this.

whosthedaddy07, The export KJ gets the same TSB 08-005-11 for Glow plugs as the North American model according to this doccument:

http://www.google.com/url?sa=t&rct=j&q= ... 8XbKm32Agw

Look at page 131, 132 for particulars on the ECM part number updates, etc. Before any procedures are initiated by the dealer you should personally inspect the new glow plug control module and make sure that it has the correct part number on the unit itself and not just the box it comes in. As per the TSB it should be part number 68090431AA. If it has part number 56044671AC, it is the wrong one. That one is for ceramic plugs. If the part number is blacked out with a marker, run away!

Thanks Everyone for this info my heads spinning with info overload now,
Funny you said that ive got what you've said part 56044671AC in a 68090431AA box and blacked out so i took it back to the dealer and complained so they reordered one direct from Italy and quess what they sent a exact part as i took back plus crossed out with black marker to again the dealer was surpposed to be on the case but they have'nt heard anything yet that a week and half plus the service department hasn't looked up about tsb,
So how do i know if 11v or 7v are the ones for my jeep i did a voltage test a while ago at th gp's and that was showing 7v thats why ive been quoteing 7v in the past , the only reason im looking at putting original plugs in is this starting problem ive got first thing, the machanic who did all the work on the engine earlier on in the year as i found out a couple of weeks ago he fitted cheap crap one' in, plus the bosch 7v one's he took out seem to be the wrong part number to, so its a process of elimination from the start again ,

whosthedaddy07,

This thread is more confusing than it needs to be. You have a 2005 KJ, so that means stock it had the 7volt ceramic Bosch glow plugs. Here is a breakdown of the glow plugs used in the Jeep applications over the years...same as previously stated by mr mopar.

2000-2004 KJ 2.5l & 2.8l CRD 11 volt standard glow plug, these take 10 seconds to fully warm up, straight voltage

2005-2006 All KJ 7 volt ceramic low voltage fast glow plug, 2 seconds to fully warm up, PWM

2007 KJ 5 volt Bosch metallic fast glow plug, 2 seconds to fully warm up, PWM

I hope you find what you are looking for.

Thanks for that
Do you now what make were original fitted in to them ( mopar or bosch ) or part numbers which would help nicely as the jeep dealer dont stock original anymore only the new 5v ones said they cant get them as there superseded now with 5v,

Good to know.
So what '05, '06 Cherokee with 11 volt plugs is this referring to?

JEEP LIBERTY/CHEROKEE(KJ) 2,8 CRD VM (11V GLOW PLUG) 2.8 4 110 12 11/02->01/06

http://www.etecno1.it/diesel-glow-plug- ... -p-10.html

All the glow plugs were produced by Bosch.

The reference for 11 volt glow plugs on the 2.8l VM from 2002-2006 might not be correct on their site. Then again, there may have been some Euro III KJ sold in the middle east countries, Africa and other regions during those years, but that would have been very low volume. The Eurozone had the Bosch 7v ceramic gp during 2005-2006.

Just for curiosity, Could you program the ECU for 11 volt plugs?
You said that the 11 volt plugs were "straight voltage". Does this mean that they are rated to take battery voltage? I know that the battery dips at the high current required to heat the plugs but do the 11's still need to be modulated (regulated - PWM)?

It seems to me that there are a lot of availability for these 11 volt plugs in other brands.

You say all the glowplugs were produced by bosch do you know if these were the original ones 0 250 202 038

Bosch 0 250 202 038 are 11 volt. According to the information in this thread, you don't need these.

The years and vehicle application is here:
http://www.bosch.com.au/content/languag ... _Ready.pdf

Ive just looked on the bosch site it doesn't mention 11v it doesn't mention any voltage at all which is strange this is from another site in the UK

Jeep Glow Plugs - Jeep CHEROKEE (KJ) 2.8 CRD, 2776 cc
Car: Jeep CHEROKEE (KJ) 2.8 CRD, 2776 cc
From: 11/2004 To: Present
BOSCH 0 250 202 038 Glow Plug
To construction year....12/2004

Yes, I know. There is some conflicting information.
The pdf I pointed to is from Australia, maybe that makes a difference, but on page 52:

0 250 202 038 11volt 10x1.00 ..... etc

Thanks for remaining neutral about this. Right or wrong, I have only been trying to help.

Yes some conflicting info and thanks for the help its made me look twice at everything now 11v 7v 5v no wonder were here there and everyware.. im going to give jeep a ring tomorrow see if they can shed any light on this ah ah ah ah ah plus ill try my local car spares place,

nursecosmo provided you with the TSB information. See if you can definitively determine your ECM (I think Jeep calls this a PCM) flash serial number and check it in the document.

Eg, I know that my '06 Jeep ECM is part P56044 and my current update is 776BB so according to the document, I need 08-005-11.

But I believe that, from what has been shown here, you probably need the same flash as us.
Welcome to 5 volt plugs!

Or join the dark side and go with the new 7 volts. Resistance is futile

First of all Squeeto i send my apologies i stand corrected 0250202038 plugs are 11v i phoned 3 car spare place today and they all quoted these plugs so how many people have had 11v gps off them and still had starting trouble's oops, Ive got jeep UK on the case of the TSB flash they said they would get back in touch in the next couple of days, but i still havnt got the latest module for the 5v plugs, jeep keep ordering a new one but keep getting the old 7v numbered one back and black markered out,

That's what nursecosmo said. Did you see his post?
