Hi All. Haven't been on for a while, but now have a problem starting. My 2006 2.0 CRDi gets a little reluctant to start when the weather is cold. This began latelast winter but problem disappeared through the summer. Today, with only second frost of winter, started reluctantly and a fair bit of smoke until it settled after 10-15 seconds. Then no problem.


I suspect one or more failing glow plugs but have limited experience of diesels. So questions are:



1. Are glow plugs the likely problem?



2. How easy are they to replace? (I have done plenty of petrol spark plugs but never a diesel.)



3. Does quality of replacements vary? The internet seems to have prices from £5 to £20 plus per single plug!



4. Any advice on doing the job or should I leave it to a professional?



All advice gratefully received!

Hi Jimreed


I would check that the glow plug circuit is getting power and staying on long enough to heat up the plugs.

Maybe worth investing in a new set of plugs if the old onesare originals? you need to take the old ones out to see if they work.



Not had to do them on the Kia, but would suspect same as other diesels?

Others on this site maybe able to recommend a make, but I would go for a known name make.

This may seem like a silly question but are you allowing the 'glow plug' light to extinguish before cranking the engine? If 'yes' then you may be right about where the problem lies...if 'no' try it first before spending any money!

Good point, Richard, thank you. But I am fairly careful about waiting for the light to go out. It seems to take longer in cold weather, which I suppose is only logical.

Back in the bad old days when I still worked for a living, (retired now
), my mate used to have trouble starting his Ford Escort van on cold mornings. He used to let the glow plug heat up and then he would turn off the ignition and then turn the glow plugs on for a second time. He claimed that the engine started much easier after the second heating. Might be worth a try.
Regards, Mike

Hi matey,


i think its a easy job, but i think there is a tool to take them off without damaging the conectors ??? i had a look through my Machinemart catalog some time ago and they look like a pair of pliers ???? have a look on ebay or machinemart you will find Halfords to be expencive and go for BERU or BOSCH as a brand, although NGK and i think Champion also make them and theres nothing between them exept the price ???

Glow plugs are most likely, you need to remove EGR cooler first to be able to get access, bit of a work up but not too bad. NGK are decent enough and will last.

Nice one, Lance, thanks. I'll have a look at the "pliers".
Yes, Halfords look pricey but quite a few sources forBosch so I'll probably go for them or NGK.

Thanks, Mr Kia.


Yes, the job doesn't look beyond me. I used to rebuild my own engines thirty years ago but opening the bonnet these daysfor some jobs such as electrics can be quite discouraging! And yes, I think NGK or Bosch are probably best balance between quality and price, now I've looked into it a bit more.
