I usually never have a topic because i use the (HELPFUL) search tools. However i could not find exactly what i need on "how to change glow plugs.

Here is the story. About 5 days ago my glow plug illumination would sometimes not come on and the car would still start. Yesterday it (my 86 300sdl) did not start and the glow plug lamp is not lighting. I came to the conclusion that it has to be my glow plugs. I've also called around and the mechanic said most likely that what it is (glow plugs). He also said it will be $300 to replace. I've changed spark plugs many times (in American cars) but i have never changed glow plugs. Is this something i can do myself or should i let it be done by a mechanic? and would i have to change all the plugs?

the plugs are $10 piece and i don't want to spend an extra $240 for something i can do myself.
