So, are all new plugs, whether 5v or 7v non-ceramic?

Not to hijack...but what is the general consensus as to the "cutoff line" as far as the region that will get acceptable performance from the 7v plugs? I'm in central NC and next year...I'm planning on the whole shebang....timing belt, rockers, Weeks Stage 1&2, head gasket, studs, glow plugs....etc. I'm thinking the 7v plugs would be enough here in central NC as it doesn't get to horribly cold....usually in the 30's/40's during the winter. Doesn't drop below 20 too often...only a few days a year. Average temp in Wendell in January is 45 according to the weather site.

I live outside DC and the 7V ones were a huge step back from the originals. Changed to the 5V ones and have much better performance. Just go with the 5V.

To test the voltage, one doesn't simply unplug a glow plug and measure the voltage at the plug cap right? It needs to be cycling at the time right? Which seems impossible to measure.

I'm getting a P1263 and was just planning on ordering the 7v since IDParts says not to run 5v on a 7v system but after reading this thread I'm glad I haven't ordered yet.

My KJ is from the south and as far as I know has the original GPs so I assume it is still 7v.

If there's any chance at all of taking a trip to the Northland, or a winter mountain camping trip, just use either brand 5V plugs, and you won't have to worry. AFAIK, none of the 5V plugs have failed when used with 7V programming. The only problem is the CRD actually starts better. :JEEPIN:

Sounds like a good problem to have!

Glad I stumbled across this thread- I'll change my order. I thought I read that it would show a code, glad to know it won't.

Thanks guy,

5v glow plugs for the win!! My jeep starts great...gone all season now, in negative temps, even forgetting to plug in my block heater a handful of times...but she still started right up :)
Thanks for all the info!

So I have P1263 which should be #2 glow plug. I ordered one Etecno 7V steel plug from IDParts. Then I found this thread and am going to order a 5V plug instead. Is the 5V steel Bosch plug better than the 5V steel Etecno? Same price.

I don't know if there is a performance difference that's even measurable.

I'm using the eTecno GX2123. Visually it looks as if there is a bit more surface area at the tip than the Bosch, but I don't know if that even makes any difference. I just figured bigger tip = more surface area = faster heat transfer to the surrounding environment. Truth is, I don't know if it makes a difference or even if it is actually true. Just a casual observation based on side by side photos.

Can anyone please help, or send the link where I can find this? Needs to be for a 2005 Jeep Liberty Sport CRD, thanks a million!


Make sure you use anti-seize on the re-install!

I've seen other posts saying to absolutely not use any anti-seize. What's the consensus?

The thing about anti-seize on the threads is that it changes the torque rating and feel - and it becomes REALLY easy to overdo it and either shear the plug in half or damage it. I have used anti-seize but when I do, I only tighten the plugs with a 3" long 1/4" socket wrench and only just hand tight. Probably translates to about 10-12 lb-ft normally. You do NOT want to overdo it at all.

Received a check engine light & PO671 fault code over the weekend. Thought it was from changing the MAP sensor although the check engine light came on 2 days later after changing the MAP. This is for short in #1 glow plug. Cleared the code with scanner and it returned immediately. This is the first glow plug failure I received in 145K miles. Took it to my shop and had them change the glow plug as I had no time to do it. He replaced it with a new plug and everything is back to normal. Luckily it was plug #1 and easy to get at.

I just got the vehicle and old glow plug back from the shop. Luckily the ceramic was coming off the internal wire as powder. You can rub your finger over the tip and it is just like ceramic powder.
