Hey all,

On the subject of glow plugs, my FD 2009 sometimes has difficulty starting. Most of the time i glow it, let the light go out, and start it fine. But sometimes (such as today), it'll take slightly longer to start than expected, and in some cases (such as today) it'll shake the car unevenly as it splutters trying to start. In these cases the battery light sometimes lights up briefly on the dash as it turns over.

Time to replace the glow plugs? No idea when the previous owner replaced them. Or look into something else?

edit: this isn't cold weather btw, we're talking at least 12'c. Probably should have made a new topic but wondering if it's a similar problem.

There is no set timing to change the glows plugs. It's on an "as required " basis. I believe they still make a difference at 12 degrees... Could be a combo of factors  maybe.. Bad fuel?

[eXDee]

Fuel is from a high turnover Caltex with TechronD etc. Should be decent quality.
I've fueled up at many older and lower quality stations without an issue.

It did the same thing today, no off balance shaking but a long time to start.  I used it after midday in 23 degree temperatures, plenty of time for the air temperature to warm up.

Perhaps I'll grab a set of plugs anyway just in case... It's 123k on the clock and I have no idea if they have ever been changed

Shop around. Last time someone checked they were only around $100 for a set of 4 I think... (Ebay)

[eXDee]

Found them in the links section. Still some left! Will order.

Wondering when to replace my battery. 6mo ago the mechanic seemed to think it was fine enough but didn't give detail of what tests he ran (if any). I can't see a date of manufacture sticker on it so i might have to pull it out to see if it's on the side.

640 CCA 135 RC. Says "Commercial" on the side. Doesn't say how many AH.

What's meant to be in these FD CRDi vehicles? I did a search and got mixed results.

This ones an N70ZL which is too long for the tray (no biggie) so probably something a bit smaller is the factory size. This seems to be the sized used in the Tucson/Santa Fe. Not cheap at $300+ from supercheap either!

[Dazzler]

The Diesels do need a more powerful battery than the petrol, but not sure of the exact model. Most specialist battery places would have the correct info I would imagine. Wait for a special (supercheap have 20% off sales sometimes)

I got a Supercharge SMF65L for $200 delivered and installed. Would have payed $165ish if I installed it myself.

This is for a GD, mind you.

Maybe get the battery checked out before getting glow plugs. Usually glow plug issues are associated with lots of smoke at start-up.

[eXDee]

I'll start the car and look for smoke. I don't pay a lot of attention to the exhaust when I start the vehicle. If my AT fluid needs doing again (thread in other forum), i'll ask the mechanic what he thinks of the glow plugs.

[Phil №❶]

If the plugs are not operating, the smoke will appear as a white colour, not black.

from what your discribing,I would be more inclined to head to battery issues,I have two diesels and the only time I get symtoms as you have discribed is when the battery power is low,not saying that it is not the glow plugs,but both my diesels have done well above the milages you quoted and their still OK,again the symtoms you discribe only time I have them with my cars is when the battery is low,or I get a loose earthing point.

[nzenigma]

If you go to Supercheap don't just get an "i30 battery". Your diesel has a larger battery than does the petrol i30.
A quick check with a multimeter will check voltage to the glow plugs and ( on the ohms range) their condition. Check each one individually. Should be 1 to 6 ohms. If one is higher, replace them all.

[beerman]

As Rick has said, having had 3 diesel hyundais the only time I have had starting issues is when the battery is on the way out.

On both occasions they were replaced by my mechanic for $180 odd.

The diesels need a truck load of power to kick over, and a poor battery will struggle to deliver the power.

On the plus side they seem to last a long time.

[eXDee]

Bumpity bump!

I finally replaced em! used that ebay link posted a while back, ordered the genuine hyundai ones nearly 2 months back, and finally got the mechanic to put them in. I lack a torque wrench and getting over the back of the engine there is a literal pain, so i had them do it.

And what do you know, once pulled out and tested, they were declared faulty. I suspected as much, as sometimes there was white smoke and the initial vibration of the vehicle felt a bit uneven, but mostly it was just very inconsistent.

The car now starts after between 1 and 3 turns of the motor, ie as quick a as a gasoline vehicle.
Vibration is more consistent, engine note is quieter and sounds more like what it is when its warmed up. Unsure if placebo, but performance feels better cold too. Now i've experienced the before and after, it seems so obvious.

Now I shouldn't have any risk of getting stranded when it's close to 0'C or less!

Great news!

[Dazzler]

Good to hear eXDee

[nzenigma]

Good news @eXDee , and thanks for coming back and telling us how you got it sorted.
 Many don't...have that good old 'Kiwi Courtesy' 

PS.  Now your car will be perfect in Wellington. Sorry I'm missing the snow.

Maybe this is a bit too late guys. But for the future here is a good link that I found useful for anybody wants to do it: Glow plug replacement on a Hyundai i30 CRDi
Also, remember to do this when the engine is warm. That's what I understood from this forum too.
