Check the owners manual, but lets see if I can remember off the top of my head!
Oil 8 quarts.
I think the last time I changed the coolant I had to add about 8 quarts back into the system, but I cheat I only drain the radiator.
The rear end is about 1 and a quarter bottles of the Mobil 1 75w90 gear oil Autozoo sells. Just shoot it in until you can stick your finger into the fill hole and feel it.
The trans I forget, probably 6 or 7 quarts.
Power steering is probably a couple of quarts.
I use Mercedes coolant and power steering fluid, everything else is either Mobil 1 or Amsoil. My Mercedes only get the best.
