Have any of you changed out the pre heaters/glow plugs on your engines ?

800 hours on mine and I have not.

I disconnected mine. They still look brand new.

I did mine on the sale. I was told that if they fail & fall in the internal motor damage is vast.

thank you i'd better check mine.

I think you need something like a 24mm socket. Of course it's the only part on the engine that needs it.

 

[05bill]

thank you sir

How would an air heater failure cause Vast Engine Damage??

 

[05bill]

i think it is possible for pieces of heaters to get sucked into engine
