I just bought 95 C280, how do I tune up
 

I just bought a 95 C280 and I can't seem to find a repair manual on it anywhere. Only the disc, which I havn't bought yet,(hopeing to find a paperback book).
Anyway I wanted to do a tune up, plugs and wires, rotor and cap, and the fluids. But Autozone says it dosn't have a cap and rotor, and only 3 wires, which they can't get.
I was hopeing someone could tell me what I should do as far as general maintenance.
Thanks

Oil
Air Filter
Coolant
Transmission Fluid
Differential Fluid
Tire Pressure
Tie Rotation/Balance
Brake Fluid Flush/Bleed
Power Steering Fluid
Wiper Blades
Brake Pads
Wheel Bearing Repack(if possible)

Just to name a few

You can get virtually all parts for the car at Fastlane at the top of the page. How many miles on the car? Has it had a new wiring harness? Changing the plugs is relatively easy but if it has not had a new wiring harness getting to the plugs is probably going to ruin the wiring harness so be prepared for about $750 there.

The reason why you can't find wires, cap and rotor at Autozone is because your car doesn't have them.

Your engine has a coil pack, with coil on plug technology, with three coil wires, and three high tension leads, which piggy-backs to the next cylinder. So basically, you have three coil wires and three high tension leads.

However, these coil wires rarely go out. There is no scheduled replacement interval.

Oh, one more thing.

These engines were not designed to run on platinum plugs. Just use the plain copper core, non-resistor Bosch or Beru spark plug that Mercedes suggests.

Changing the oil on C280
 

Thanks for the info, Just trying to change the oil has been more of a problem than I expected. Dose mercedes make a special tool to get the cap off, where the oil filter goes?
Looks as though I'm already going to have to replace that. I must've cracked it when trying to get it off, which I finially gave up on and just decided that new oil would have to be good enough until I could figure out how I was going to get it off.

There is only one way to tune up a 104 ..
Bosch F8DC4 plugs at .8mm and three new coil to plug connectors ... that's it !
Until you do that, you are wasting lot's of $$$$$$$$$$$$

BooYaa, Cramer !!!!

They do make a nice, overengineered metal cap wrench - about $30 from the dealer as I recall. But it seems like there must be something in the aftermarket that is the right size. The nice thing about having the filter on top is that you can change the oil and the filter independently if necessary. But if you cracked something you'd better keep an eye on it. Although frustrating at times you've just got to stick with it - these cars are generally not that hard to work on.

Oil filter cap wrench?
 

Yes, there is. I got mine from Advance Auto Parts. They have several different sizes, with and without fluting; you'll need to find the right one for your oil filter cap. Cost me about 9.95, as I recall.
