Stuck Glow Plug!!!

[yvairguy]

So i got to changing my glow plugs yesterday and i get to #4 and the head was already messed up..... i know the PO didn't wrench on this thing himself so some mechanic left me this little jewel. I tried to get on it with a wrench that hit on the flats and nothing. Luckily i have a set of these extractors that i used to use when i was in business and they saved the day.

It pays to be a Tool Junkie.

Got My extactors from Sears when the were on sale only used it one time so far. Did not have them when I worked as a Mechanic may Years ago.


A Never-seez type Compound on the threads of the Glow Plugs is helpful. However, the Engines with the Iron Cylinder Heads don't have near the problems with stuck Glow Plugs like the Engines with Aluminum Heads do.


I had 2 Autlolite Glow Plugs that unscrewed OK but the Tips were swollen on that needed a Vice Grips and a lot of force to get out.

i have only used them about a dozen times or so but every time i have they have saved my bacon, i have also lent them to friends a couple times. they will even grip case hardened like butter
