Tips for changing glow plugs in my 300tdi
I am going to replace the glow plugs on my 300tdi and wondered if there were any tips on how to do it before I start. I wondered if it was worth doing some prep work first such as warming up the engine first or applying Plusgas for a couple of days.

Only just starting my maintenance "journey" as I want to be able to look after the truck myself as I have to watch the penny's! I really don't want to break a plug in there as I really don't want to have to remove the head to get the broken bit out!!

Thanks for your help.

Mick

Not specific to a Tdi but a bit of penetrating oil ahead of time doesn't hurt and the other general rule is don't force anything, once you get it started, take it out carefully and if the plug starts to tighten up then soak it with more juice and work it back in and back out until it comes out freely. I once spent several hours working the last plug out of a VW diesel because the alternative was considerably more painful! ---

Agree with what's been said already they can get tight and do squeak (yes really lol) when they're coming out if they get tight wind it back in a few turns more lube and wind out again just take your time WHAT COULD POSSIBLY GO WRONG

Why are you changing them?

I only ask because on my current 300tdi and the 200tdi I owned before it I never felt they were used or needed. Even in the depths of our mild English winter -5 to -10C I have always just turned the key and started the engine instantly without having to wait for the heater plug light to go out.

Do we really need them in our moderate climate?

There are two reasons for wanting to change the plugs. First one was that last winter I wanted to run the engine during the very cold days as it does not run often enough, and as the truck was newish to me and I had not changed the coolant myself, I got a bit paranoid and wanted some heat in the block. The engine was reluctant to start an I was flattening the battery. I feel that is likely to the battery not being the best and that is something I hope to change in the next couple of days. A cold day really takes its toll on it.

The next reason is I don't want them to become seised in the block, so more forward planning really - and at £10 for a set it ain't as though it's breaking the bank to do it.

And I suppose another good reason is, if we get a cold and snowy winter, I would be disappointed if I have a capable vehicle and then can't utilise it if it won't start. The beast from the east was a good example of what we can perhaps expect on a more regular basis.
