Glow Plugs...

Hi,

How easy is it to change them?

My car really struggles to start in the cold and I am hopeing new glow plugs will help? (views??)

How much is a new set?

How much would it cost roughly to fit a new set?

My car is going in for a service next week, so was wondering if it was going to be worth doing?

Cheers,

Ben

I've been pricing them recently and they start at around £6 each. It's a piece of cake to get to them and they just screw in like spark plugs. I wouldn't even waste the money getting a garage to do it unless you really doubt your own ability :)

Well, I'm going to get them to sort some other bits too, thinking of things to make it worth the hour's labour they'll charge me for 5 mins work...

I paid £40 for a set from local motor factor, think they are bosch (I may be wrong). They are easy to fit. Screw out with the smaller of the spark plug removers - Halfords £4 and new ones screw in.

What I will say is be careful with the rail that covers the glow plugs, if it snaps it an expensive, awkward fix.

Depends on which engine you're working on aswell. The 2.0ltr twin cam has to have the rocker cover off to change the glowplugs, and they're more expensive than the 1.9 plugs aswell. Still only about £9 for genuine VAG ones from David at Sere Motors.

I see from your avatar you have a Mk1 Leon?

I got 4 glow plugs from my local SEAT dealer recently for £56 inc. VAT.

They're a doddle to change - engine cover off, move the foam padding stuff out of the way, then you can get to the glow plugs on the front on the engine (you will see the black harness connecting to each plug). Carefully pull off the harness on each plug then remove the plugs. Just be careful when putting the new ones in not to cross thread them because that could be expensive to repair!

You will need a long socket drive though to reach them (at least 6 inches I'd say, I used a 12 inch one!). I think it's a 10mm socket that fits on the glow plugs.

Also for the plug on cylinder 3 (3rd from left when looking at the engine from the front) you may need to unscrew a couple of the screws that support the intercooler pipe so that you can move it just enough to get the extended socket in.

I have some pics at home that I can post up later when I'm not at work.

That might make it a lot easier actually, I did mine after the car had been stood all day outside at work and some were a bit tight!

Here's some pics anyway to help others...

1) Foam padding that needs removing (the highlighted silver ring joins the two ends of the foam - open up the ring to allow the foam to come under the cable that goes over it at the front):

2) Glow plug location and screws that when removed allow intercooler pipe to be pulled away just enough to access glow plug #3:

3) Glow plugs #1 and #2:

4) Glow plugs #3 and #4:

5) Proper tools for the job ;) :

If so it is just the engine cover mount and can be pulled off the stalk! (They are meant to stay attached to the engine cover but mine at the top in that pic came out)
