fluid capacities ?
- Engine oil : _________
- A/T Fluid : _________
- Coolant : _________
- Brake Fluid : _________
- P/S Fluid : _________
also do you guys know of a good place to find a service manual that does not cost an arm and a leg. (i'm looking for something along the lines of a bentley manual)
thanks
- Engine oil : __8+ qts._______
- A/T Fluid : _4 litres unless drainng the torque converter, then you'd need 8________
- Coolant : ____the car holds about 2.5 gallons_____
- Brake Fluid : _____1 litre is quite ample for a flush____
- P/S Fluid : ____tandem pump?_____
thanks for the info, i just needed to capacities, because i'm doing some simple maintance on my wagon. (i don't think i'll touch the P/S fluid)
2. A/T Fluid : 8.0 US qt (7.5 L)
3. Coolant : 10.6 US qt (10 L)
4. Brake Fluid : approx. 0.5 US qt (0.5 L)
As correctly noted by uberwgn, make sure you use the special Fuchs fluid for the self-leveling/steering. The part number is on the reservoir cap. With this one common reservoir system, the older fluid (just for self-leveling) should not be used in the W210. The capacity of this really does not matter because you cannot get all fluid out of the system unless you dismantle the entire rear suspension. Just renew what is in the reservoir and if you want to exchange more then start the engine and drain the return line while adding new fluid to the reservoir but this should not be necessary and it still does not flush the fluid in the rear shocks.
BTW, 7.5l of ATF fluid includes daining the TQ converter ?

What year is your wagon? The later ones do not have a drain plug in the TQ.

The 2000's do not have the plug but some 1999's do not have either.
The filter under the reservoir cap provides back pressure to control flow. I know you said you don't plan on servicing this system now but for future reference, just suck out the reservoir and refill. After a couple of refills you can replace filter (aka suspension filter). Filter and OEM MB fluid available from autohausaz.
For correct transmission service you will need special 'dipstick tool' for final setting. Make sure trans fluid temp (not engine coolant) is at 80C. or you can end up overfilling. Good DIY on 722.6xx trans service on benzworld.org/w210 section.
For service procedures two choices are 1) MB Service Manual DVD. About $150 from 1-800-MERCedes or 2) Subscribe to alldatadiy.com. Lots of cheaper CD's on ebay but most people seem disappointed in them.

This is no different from transmission or power steering flush. Dis-connect the return line (low pressure) and collect the fluid being pumped out with engine on. It is definitely a two person job.
No one but MB dealers sells the correct (hydraulic and steering) fluid for W210 wagons here in the USA. It is MB sheet 344.0 and part number is 001 989 20 03 (this number is on the reservoir cap and it is there for a reason). The OEM is Fuchs and that is what th MB dealers sell (not in Mercedes bottle). See picture.
What Autohaus and other sell is the older MB sheet 343.0 fluid (MB part number 000 989 91 03). This fluid should not be used in the common reservoir system such as what is in the W210. The older fluid is only for self-leveling because the power steering has its own reservoir and fluid. The W210 has a common reservoir, however.

I have flushed a BMW power steering fluid this way. There was a website on this on the Internet and this method one of the three methods and the most complete to renew power steering fluid.
Yes, the system has pressure but that is not hard to handle with one person holding the milk jar and the hose. The pressure is needed to pump out the old fluid. George Murphy actually has a very through writeup for renewing the self-leveling system this way (using a couple 200 lb bodies jumping in the rear to renew the fluid in the shocks). The return line has coming back from the cooling lines in front of the radiator and the pressure is greatly diminished. The flow of the fluid needs to be contained or fluid will be everywhere. I am sure you have read the 722.6 transmission flush using the engine pumping method in another forum. It did make a mess but that was due to operator carelessness.
And I started by saying "Just renew what is in the reservoir".
Putting the correct fluid in this system is more important than using the wrong fluid and change. Someone has been saying in many forums about using the Febi OEM fluid in W210 and that is the wrong fluid for W210. Mercedes put the new part number on the cap to caution people that it has to be that fluid.

1 - Remove the fluid return line from the top of hydraulic fluid reservoir and remove fill cap - use a piece of scrap hose to route return line oil to a 1 gallon container placed under the car to catch old fluid as it comes out.
2 - The filter is located under the fill cap. Remove old one and leave cap off reservoir.
3 - Have 3 liters of new fluid ready to pour into reservoir - take lid off bottle and remove foil seal because you have to be fast about this. Use a turkey baster to remove all old fluid from the reservoir, then add about a liter of new fluid.
4 - Have one friend start the car; have other (heavier) friend bounce rear of car to exercise rear suspension while you pour new hydraulic fluid into reservoir as it is pumped through system and into catch bucket under car - this is called feed and bleed...you have to keep feeding in new fluid as the old fluid is pumped into catch bucket under the car.
5 - When new clean fluid emerges from return hose, shut off engine (and stop bouncing rear of car). Fill reservoir to correct level as marked on side of reservoir. Install new filter and re-connect return line to closure cap assembly. Start car and check for leaks and top up fluid level if necessary...
If you have not added fluid to the reservoir, then what you have is a synthetic fluid. It is very expensive.
It sounds like you have a leak in your rear (self-leveling) suspension. Many things can leak but the most probable one is one of the two rear "shocks" so you need to inspect where the leak is coming from. They are not traditional shocks because they are really hydraulic cylinders.
The rear suspension shares a common reservoir with power steering so your fluid level might be too low therefore the power steering message.
I would not drive the car until you can verify that there is enough fluid in the reservoir.
I am just planning to suck&refill the reservoir of my w210 wagon (2001) PS+self-leveling.
Not a complete flush, only replace in the reservoir.
My question, how much oil will I need for this?
Thx
