Once you've done the first 1/4 turn, wind it back in gently to move that WD40 down the thread a bit. Do that again for 1/2 a turn and wind back in gently. Better not to try and remove them just by anticlockwise movement alone.

Thanks for the tip. My E350 Mercedes had failure for glow plugs and had run for almost 95K Kms. Garage mechanic said its risky to remove them as they may snap and head lathe is the only solution to remove, if they do snap. I advised them to oil using deep penetrating spray. Did the oiling for 2-3 times in intervals of few hours for 48 hrs. Kept the engine running for 30 mins before starting the removal. All 6 plugs came out smooth with manual fixed wrench. Replaced and work done

Wow surprised they went so fast. My BMW diesel glow plug module finally is going out after 255k km. But the glow plugs are fine.

3 things jump out at me (1) pre spray with a proper penetrant and leave for 24 hrs (2) Get the engine hot first, yes it will have cooled down a little by the time you start to remove them (3) Use a deep socket that will fit over the whole length of the glow plug (3) Standard WD40 is NOT a penetrant, it's a rust inhibiter / moisture dispersant.

Just my Golf mark 5 glowplug after watching this and reading this comment. Ran the engine nice and hot and while ticking over removed the connectors/harness to keep spraying GT85 penetrating spray around the plugs. Switched off engine and using a proper deep 10mm socket gave them a go. Omg they felt tight, so I just went very slowly and every time there was a tad of movement and tightened again so back and forwards, back and forwards kept spraying GT85 when it was slacked off then tightening again to try and get the fluid into the threads. 2 loosened nicely quite quickly. Other 2 were much slower, so it was just case of being patient turning a few mm back and forwards, spray, repeat, repeat repeat etc not getting greedy with exerting too much force and slowly every time I was counting how many quarter turns forwards and back i was getting and eventually i got them all out. Took just over an hour to get them all out so patience is everything! New ones in, start up and job done all engine fault codes gone! Thanks for the video and the useful comments. 👍🏼😁

Good advice... Another help is applying counterforce with your other hand on the ratchet head while you wrench it off. It helps keep the socket perpendicular. I've snapped things before by letting the socket lean over while applying the torque.

Thanks for the video - it was very helpful for me. I did this job with my old 2004 Nissan X-trail 2.2 with 250 000 km on it. I had to exchange only one glow plug. I used torque wrench in order not to exaggerate with the force and the glow plug started to rotate at 25 Nm. According to the spec should be tightened with 20.5 Nm so it's something similar. Of course I used also WD-40. The shape of the thread is perfect. The rest of the glow plugs show resistance at 1.3 Ohm level so I don't touch them for now.

Also, they are all bashed because of the way you use your rachet, lots of short turns without taking up the slack each time. You should have the proper socket for a demo on KZread - or offer to show how you drilled out your extension! If they are original how have all four got alloy jammed in the threads? They look like they have been installed ham-fistedly, which is unlikely to occur at the BMW factory. If you're taking the head off then run a chaser down those threads before the new plugs are installed. I think the torque rating is just 15 lbs/ft. You ideally want to blow out the recesses with compressed air before you start spraying a solvent around in case it loosens some debris like a small stone and it gets into the bore when you extract the plug. I'm about to do my TDI which has 320,000 km on it, no record of them being changed - so I came on here to see how to do it without stripping them. I'm a qualified mechanic but I want to know what I'm up against! Thanks for your video.

Thank you for explaining the right way to do this job

Changed mine on our N47 a while back. Soaked them beforehand and got the engine hot before trying to remove them. 3 came out no problem, the 4th came out probably 1/2 way before going tight. No amount of backwards / forwards with lube did anything and in the end it snapped. After a fair bit of thought i decided to buy one of the £30 kits off eBay which have stepped drills and are designed to drill glow plugs out in situ. It worked a treat and got the majority of the plug out before the drill snapped. Fortunately the part that was left was loose in the head and wound out with a screwdriver

My advice is this. Spray WD40 and leavr it for at least 3 hrs. It takes time to penetrate. It will not work immediately. Then tighten the glow plug, minimum force but just enough to break the contact of the thread inside. You wont feel anything but it will help. While the socket is in the glow plug and the adapter bar is fitted tap it a few times with a hammer, DON'T whack it, just light taps. This will also help free it up. Then very SLOWLY unscrew the plugs... Seriously, take your time. This is the best way of doing it, trust me

@papapetad

Yeah, I like the subtle tightening start on stuff like this. It relieves built-up stress from constant compression trying to get through the threads. Lets everything relax then the tap for extra gravy points to the same end...I just go for an overnight soak for peace of mind and others mentioned warming the engine which is a great tip too especially for stuff like this where the metals are different...THEN start working it loose slowly. It's what I do with any fastener on the exhaust side too, especially exhaust manifolds and turbo flanges and such.

Good shout on the WD. You can never use too much. Allowing it to soak for days or even weeks in advance can only serve to help, even with only mild penetration. Oh and if the threads on the old plugs look like that I would suspect that the threads in the cylinder head have succumb to some damage also. Probably best to run a tap down each one and then use a straw on a vacuum cleaner to get any swarf that might have fallen into the cylinders. Then inspect for swarf in each cylinder with a bore camera before reassembly.

What you should do is this . Once it starts to move then stop and then start to tighten then the reverse That way you will loosen it Just going one way you are not getting the carbon off which is what tightens and will snap the plug . So backwards and forwards is the order of the day. PS Its normally the tip that snaps off !! be very aware as its the carbon build up that causes the seizure.

Soak for a week in thin oil. It might cause a capillary reaction as the engine goes through heat cycles. Then when it comes to removal, get the engine red hot first. The alloy has expanded. But alas in a world of so called engineering excellence some may need to strip out a lot of junk just to get to service items. What this guy is displaying is something called feel, unfortunately many folk are heavy handed like toddlers.

If you are able to get an engine "red hot" you no longer have to worry about the glow plugs as the engine will no longer be functioning.

After seeing this video I thought of checking the heaters in my Peugeot XD3P engine. It's a simple connection where all glow plugs are connected to a single copper strip. I used a dc clamp meter to check the current draw. I could read 16Amp in the first plug, 31A at second, 48A at third and 60A at the cable. Roughly 15A per plug. My battery terminal voltage drops from 12.6 to 11.5v while the glow timer is on , indicating good battery health.

There's a sudden jerk only when they break and not before. That's why if they are to break, there's no preventing this without a torque drive.

I'd be checking the head thread before fitting new glow plugs in case they need to be re-threaded 👍

great vid

The CORRECT way is to loosen them by using a TORQUE WRENCH. You should set the wrench at just over the maximum tightening torque. So if the maximum tightening torque is 14Nm set the loosening torque to 16 Nm and no more otherwise you have the terrible likelihood of snapping the glow-plug clean off! If the maximum torque is reached but the plug does not turn, further action is required before making further attempts. The biggest influence will be running the engine to full high temperature where the threaded hole will expand slightly. You could even spray the plug with Freezer spray to increase the temperature differential to help loosen them. Just be very careful al the same...

Agree with everything in this vid but a few measures not included. It's all about feel. Having been an hgv mechanic for 29 years who also had the good fortune to have worked for a company for 8 years that restored and reconditioned old aircraft ground support equipment I have had my fair share of battles with threaded items that looked me in the eye and said bring it on, you've got two hopes, Bob Hope & no hope of getting me out 🤣 So, plenty of lube to begin with and gentle work with the socket and ratchet while using all of your spidey senses to feel if there's any rotational movement, a feel of plasticity or rock solid. Plasticity is a huge warning telling you to stop 'cause you're about to wring its neck. Rock solid says get some heat in it and keep lubing and trying with feel and caution. If you're lucky enough and it moves, unscrew a flat at a time lube and wind back in. This serves two things. It breaks off crud but importantly it takes much needed lube back into the threaded hole. Keep doing that and before you know it the thing is freeing up and you're on the home straight. Sadly the "feel", takes a while to develop but once you have it is as valuable as hour most prized Snap on tool. The feel also works equally well as a torque wrench.

Hi George removing glow plugs is a bit of a hair raiser , most important its most recommended that the engine is at running temperature before attempting to remove glow plugs , also its recommended that the treads should be re-cleaned with an M10X1 Tap before re-assembly , BMW also have a problem with the control unit for the plugs which I would recommend you to replace when you have got the induction manifold removed it makes life easier and you are sure that the plugs are working properly its not worth taking chances

Mercedes manual actually even specifies a max loosening torque to the glow plugs so you wouldn't snap them. Also ceramic anti seize is to be applied on the long shafts between threads and the tips.

When I've done it a warm engine helps, if you get a sticky one use more penetratind oil and drive it in and out a few time to loosen the rubbish on the threads

Also, tool suppliers offer glow plug sockets for most popular glow plugs. Also a T bar, to fit your socket allows a better chance of not damaging your glow plug, compared to a ratchet.

Do you recommend tapping the threads in the head before inserting the new glow plugs? Great videos!

If they don’t go in cleanly yes👍🏻

I prefer to use a T handle bar with the socket for more control over the angle. Then you can't bend the glowplug. Secondly, the glowplug is sealed to the cylinder head, therefore a penetrant (not WD40), will not be able to be taken into the threads by capillary action. If it will not break free, then try to tighten it very slightly and work it back and forth gradually. A penetrant will help once its broken free.

Your videos are very useful. I really want to give this a go. So you are saying maybe 24hours before doing this spray them with WD40 or some kind of displacing fluid. Then before doing the deed give em another soak for about 30 minutes and slowly get them out. Also, should you soak the new ones at all? What would happen if I was to snap one? Can the car still run or would this do serious damage to it? I also have a E87 N47 engine 57 plate. 92k miles never changed plugs since becoming the owner 8 years ago @ 34k miles.

Brush new plugs with fresh engine oil before installing🤟

If they start moving spray em and run em back in then back out spray em run em back in back and forth as such and walla

Mount the new glow plugs with 15Nm. Mind you: the plugs break at a torque of 35Nm! Use a torque wrench to loosen them so you don’t exceed the 35Nm while doing so.

Thanks for the comment. I've got to do the glow plugs on my vw t5 1.9 tdi. I've replaced plenty of spark plugs before but these will be my first set of glow plugs. All the comments about hos easily they snap has got me a little nervous. Lol. Wish me luck!

@@empire1771 it went really well. I was a bit nervous because of all the stories of glow plugs snapping off but i just made sure the socket was on squarely. The first one was on pretty tight but i just tried not to put too much pressure on it too quickly and hold the force to give it a chance to unscrew. Sure enough they all came out with no problems.

Yup, I have a beam torque wrench for that. The breaking torque is published for the plugs. Just take your time and go back and forth.

You could use a flexible socket coupling and a T handle.

Glow plugs snapping on removal is not a myth, some engines are worse than others, do Glow plugs on a tdv6 rangerover and let us know how you get on. Good video tho, only addition from me is get the engine stinking hot, then try remove. It has the added benefit of making the work more pleasant In winter

thank you

Hi George..good videos as usual! With the state of the old glow plug threads, did you have to retap the glowplug holes before screwing new ones? Mine have come out same as yours. All the threads are almost flat now

Thanks for the reply. Everything is back together now but the car cranks fine but doesnt start. I tightened them to 20nm and they were fine and felt tight. Theres no error codes on the diagnostic autel but its not starting at all now.almost feels like its getting no fuel. Fuel rail pressure is ok too. If the glow plug relay is dead, will the car not start at all ?

Providing it turns this works. But if doesn't even begin to turn, you have a problem. If I run my self into this situation, I put the socket and extension on the glow plug, bottom it out, and give it a couple solid walks with a hammer. This loosens off any rust, or soot build up on the end of the glow plug. And if that still doesn't do it. I have a 3/8 breaker bar that I can put on the socket, and then I can hit the back of the breaker bar while applying turning pressure. This acts as an impact wrench but you can adjust the torque and prevent it from just snapping the plug off.

On your w110 or w123 or w126 mercedes you put a ring spanner on them then lefty loosey and out they come!

I use a rubber socket and ratchet, if they are very tight, I put the rubber ratchet in the freezer for a while. :D

First off your method/ procedure is a proven and good practice. Also there are many misconceptions on the internet , especially that cylinder head removal is always the case, no this is not so!!!- However if someone is misguided enough to think an extractor has more purchase than the original M10 hex - then most probably, this would be the case after breaking the top. Also every BMW glow plug that is stuck - is not down to wrong torque but a phenomenon that I have proven time and time again, (galling) - this usually happens with metals that are similar in nature but not in this case - when you first crack a plug you may get a few loose turns and then it goes tight - This can be attributed to either carbon on the electrode and aperture or the parent threads have over time lost their running clearance.( which should be .05 to .1mm between the plug and parent thread) - So little bits of metal coming off the plug thread due to one or two frozen threads at the top, they start falling to the bottom and the threads start trying to weld themselves together. The penetrating oil helps maintain movement but eventually the plug either comes out or breaks under the torsion pressure generated. So I hope you use a (clearance tap) to restore the lost clearance or the next time the plugs are changed it will be a nightmare……. 👍

What torque do you use for the intake manifold bolts?

I work in a garage, I can assure you that sometimes glow plugs do break on removal, often even though you can unscrew them the tip can be thoroughly stuck in the hole and will shear from the glow plug body!
