Does anyone have any advice onwhat preventative service I should have performed on my 99' C280? I will be at 150K shortly. Thank You

 

You might want to think about a brake fluid flush, radiator flush/coolant, and of course, oil and filter changes
being important to keep up. I'm not sure if this vehicle/model allows for a tranny fluid flush/filter but it's something
worth investigating. All these things are pretty much standard on any vehicle with some miles.

 

The timing chain has not been replaced to my knowledge any advice when this should be completed?

 

I myself am not familiar with the interval on that particular engine.
Maybe a tech here could chime in on this one with a realistic mileage figure to replace it.
Anybody?
