Part no. Glow Plugs

Temp has dropped below 0 and very bad starting in my hands now. Fear the glow plug(s) have seized, despite the low mileage. Does anyone have the parts number for the glow plugs available? Will make explaining to dealer here easier. Many thanks!

Are these glow plugs problematic? Ive changed loads on a variety of vehicles without any issues. Is it worth periodically removing, cleaning and refitting to prevent them seizing up?

Hi

When I have refitted glow plugs I have always used copper grease to prevent further seizure, and it has worked well on 300tdi's.

Should also work with TDV6

Regards

With all respect, a 300TDi is miles and miles away in terms of development from a TDV6

They are about 3 times the size of a TDV6 plug, so it's no surprise they don't snap...

Hi

Not quite sure if a 300 TDI is quite 3 x bigger than a TDV6 Glow plug.

I thought they were within a couple of mm the same length, approx. 126 mm,

a 300tdi takes a 10 mm socket and has a M10 X 1 thread size,

while a TDV6 is a M8 socket with a M8 x 1 thread size, so the TDV6 are a bit thinner, and probably by default more fragile.

I agree the TDV6 is more sophisticated as it has after glow capability and a much more sophisticated control system.

I am in a similar situation as some others here ie I have a "lumpy idle" on initial start up when cold, but nice and smooth when warm.

Changing all 6 plugs for new would normally be my first choice based on the age of my car (2005) and the number of start up cycles it has had but I am very wary of snapping them, hence I have not attempted to change mine yet.

I am currently relying on the FBH and Bell Autos remote to ensure a good start up

If I attempt to change them myself I will use lots of Plus Gas for several days before hand and possibly a freezing spray as well.

What do you think?

Regards

Jonathan

Not sure Plus-Gaz or freezing will address the problem. As I understand, it is not seized threads that cause the difficulty but the build up of fossilised carbon around the cylinder end - it's the stuff they make diamonds from!

So are there no effective additives that can be used to prevent this build up?

Be interested to see if terraclean treatment would make a difference.

That was my next plan.

If anyone up here has a Terraclean in the coming year, let me know Thumbs Up

Ive changed plenty of 200 and 300 glow plugs and without exception they have always come out, not once have I thought uh oh here we go.
Best of all they are 12 quid for 4 of off ebay!

Graham, lets see if they come out beforehand, and if they come out afterwards
