like the topic states, does anyone know the fluid capacities for a E 320 (S210) 4matics.

1. Engine oil : _________
2. A/T Fluid : _________
3. Coolant : _________
4. Brake Fluid : _________
5. 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

Our '02 wagon RWD has a tandem pump which handles both the load leveling and PS functions. The TITAN fluid is crazy expensive and only available via your friendly dealer from what I've been able to determine. How much does it hold? Probably 3 or 4 litres, I'd guess.

ConeKillerSTI

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)

Uberwgn is correct. The 3.2 V6 holds a little under 8.5 quarts usually recommended Mobil One full synthetic 5W-30 or 5W-40. The dual pump is the power steering pump/self leveling pump for those cars equipped with self leveling rear suspension, all wagons came so equipped and some sedans as an option. The pump s very expensive to replace and height adjusts off the geometry of the rear anti sway bar. Not sure of the capacity though. The dealer has that info for you. And yes the fluid is also pricey.

1. Engine oil : 8.5 US qt (8.0 L) with filter
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.

ConeKillerSTI

thanks, so in theory the steering/leveling fluid should be fine and i don't need to mess around with it.

BTW, 7.5l of ATF fluid includes daining the TQ converter ?

loubapache

Correct. You can add some if it is too low.

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

uberwgn

I typically suction out 1L of the Titan hyd fluid every year and replace it with 1L of fresh fluid. So far, no leaks/problems anywhere @ 130k miles.

ConeKillerSTI

i have a 1999.

ConeKillerSTI

i like that idea, i might just to it. some new fluid is better then none.

loubapache

Some 1999's have the TQ drain plug so I would look for it. If your has it, then it is much easier to drain a lot of the fluid.

The 2000's do not have the plug but some 1999's do not have either.

This system is under pressure from the PS pump. If you disconnect the return line and start the engine you will have fluid everywhere.
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.

The return line is a low pressure line. Obviously, one needs to put it into a milk jar or some small mouthed container to collect the fluid while adding new fluid to the reservoir at the same time. See picture with the return line number boxed in blue. As I said earlier in this thread, this should not be necessary but if one wants to have a clean flush, this is the way.

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.

RichardM98

Have you actually done this? I have and there is substantial pressure. Removing the line from the cap and sticking it in a milk bottle will likely result in an engine compartment covered in oil. Hardly good advice to someone just starting out to do their own maintenance.

loubapache

I have done exactly this on my W124 wagon but not on my 03 wagon. I see the new fluid is so much improved and there is really no need to flush the W210 system. The system are not that different, even with the common power steering reservoir.

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.

tirona

i have done it that way also a couple of times, no splashing at all.

loubapache

Here is the George Murphy procedure that I dug out from my hard drive. I have edited out a couple things because he sells MB parts. He also has a similar flush (with engine on) writeup for MB power steering 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...

Where do the self-leveling lines run on my 99 E320 AWD wagon? I recently started noticing a small leak on the driveway inside my rear driver side tire. A few days later, the P/S fluid level code popped up on the dash...

rshoemaker

Also, how can I tell if I have synthetic or non-synthetic steering fluid in my car?

loubapache

rshoemaker:

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.

Hey Guys,
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
