I may have to in the future change a glowplug in the future Son in laws car as above. They look real fragile little feckers and I'm concerned ( after researching the www ) that they may be seized/shear off or spin in the head.
I'd doubt they ever been replaced before either so with 6 years and 90k on the clock whats the best way to go about it??
Should I dribble penetrating oil into the threads a few times a couple of weeks before hand ( never thought that it did any good before on anything else I've ever tried it on) or try dribbling diesel down the holes ( a lot of mates swear by the deisel trick but never tried myself). logig would also dictate to do it wth the engine as hot as possible ( any thoughts on that?)
Really not looking forward to it.
As usual thanks in advance folks.

!2 hr soak in Phosphoric acid --- aka Naval Jelly or alloy Wheel Cleaner.

worth giving it a try first, lightly. i was amazed how badly seized they looked on a citroen hdi, but they came out no bother. if it seems too difficult do what BT said.

If it snaps it will be a BIG job like on vectras

Ive never had a problem with the cdti glow plugs. Just get the engine very hot before you take them out. Its been a while since i posted on here eh !!!

ETA is that 2 hrs or 12 hrs B.T.??

Overnight then quick spray with WD40 5 minutes before you start to pull them out

Or you could try a can of Coke, let that soak overnight. Never tried it but know a couple of people that have, and they say it works great. HTH Ray
