Newbie question -How to replace the spark plug?

[tseinsf]

Hi all,
I’m new in this forum. I just picked up a 1999 C-230k and it’s has a 63k miles on it. I would like to do some maintenance and replace the all spark plug. If I order this from fast link . Do I need to do any gap adjustment on the spark plug before I replace? I would also like to drain the brake fluid. What is the procedure? Any suggestion will be appreciated.
Thanks in advance..

For the brake fluid part, may I suggest a search under " brake fluid flush ".
On the sparkplug issue:
1. If you are getting Bosch F7KTCR, there is no " adjusting" to do.
2. I normally like to change plugs on an aluminum head engine when it's cold.
3. Apply a VERY small amount of anti-seize compound on the plug threads before installing them.
4. Use a little dab of dielectric grease on the plug boots, before you re-connect them.

P.S. Welcome to the forum.

Antiseez is a good idea. But you will find that changing plugs as early as 63K miles is a waste of time. Most MB plugs will go at least 100K miles before any attention is needed. So why bother?

I think the C 230 K's are a little more demanding when it comes to sparkplugs.
At least mine seems to be, that's why I like to change them at 50 k miles.

Even if the plugs are good, it's a good idea to change them simply because they have a tendency to sieze in the aluminum heads if left too long. You can imagine how expensive that problem is! 60K is chancy - 100K is way too long, not just for the seizing issue, but for performance from ANY plug, including platinum-tipped. 100K for platinum plugs is only an optimistic marketing advertisement - makes for a good round number. They are typically only good to roughly 60-80K.
