Title: Glow plugs
Post by: stoxman on 31 December 2010, 16:30:47
Hi all,
Bit of a basic this one but I want to change the glow plugs on my 2.2DTI and I cant get the connectors off. They look like plug caps and I can rotate them, so I just pulled and have pulled the top off one of the plastic caps. This makes me think they dont just pull off and I need one of you to confirm that this is how you do it or put me right on removing them.
Thanks in advance
Stoxman

On the 6 cylinder engines they have a small nut (8mm) to hold the cable on and then a 12mm deep socket to remove the plug itself.

Mine is a 4 pot and I cant get at any nuts, if there are any until I can get the plug cap looking thing off.

You have to pinch the caps, they are a bit like a child proof bottle if you get my drift ;)

Be careful when undoing the glow plugs from the head as well, they can snap :o

Thank you people. I shall make another effort to remove them tomorrow. I dont like the prospect of them snapping. I am guessing this will be the first time they have been removed since new,  104K ago.......

Use plenty of penetrating oil (proper stuff not WD40) ideally change the plugs on a hot engine.

The glow plugs shear in half at about 35Nm so to play it safe take them out with a torque wrench set to less than this.

If the caps are how I think they are there are some horizontal marks for your fingers. Squeeze firmly between finger and thumb and off comes the cap. Think of it like a clothes peg. The plugs have a huge ring round them that the cap clips onto.

Just done a set on my 165k DTi and they came out alright :)

New set in and pushed the leads firmly home and the car starts first time now as opposed to 2 mins of cranking 8-)
