  1. Power Steering Hose Part numbers

    W163 M-Class
    It's 4JGAB54E51A223871. I assume I should replace the o rings too. Part numbers on those would be much appreciated.
  2. Power Steering Hose Part numbers

    W163 M-Class
    Hi Guys, Im losing power steering fluid from from my 2001 ML320. The leak appears to be coming from one or two hoses that have fittings at the back of my steering rack by the pinion gear. Anyone know what the part numbers are for these two hoses? Thanks!
  3. P0170 P0150 P0130

    W163 M-Class
    I don’t have a scanner that can do that. Is there anything else I can do to troubleshoot?
  4. P0170 P0150 P0130

    W163 M-Class
    The CEL on my 2001 ml320 came on today. The codes are P0170 P0150 and P0130. Any ideas? Just changed the oil. Not sure if that could have anything to do with it?
  5. Anyone tried running smaller wheels?

    W163 M-Class
    Hi, My 2001 ML320 has the Sport trim package with 275/55/17 tires and rims. I believe it's also the ML55 trim. I still have tires and rims from my 99 ML320 which were 255/65/16 and I'd like to put the smaller wheels on the 2001 ML because the tires have more tread and it will save me some...
  6. ML320 Coolant Capacity

    W163 M-Class
    Interesting. I would not have thought 2L would stay in. It makes sense though since they specifically tell you to flush with tap water first, before adding the coolant.
  7. ML320 Coolant Capacity

    W163 M-Class
    My only question is why would Mercedes list the capacity at 12L in the manual if the system only takes 10L. Is it possible, they mean it takes 12L to fill the expansion tank to the top?
  8. ML320 Coolant Capacity

    W163 M-Class
    I just replaced my coolant expansion tank and flushed the old coolant on my 2001 ML320. My manual says the coolant capacity on this system is 12L, however I have only been able to get about 10L back in when filled to the Cool mark on the expansion tank. I've tried squeezing the top radiator...
  9. AC Blows Cool Air (but not cold) , ML320

    W163 M-Class
    I just got it back from the shop and they put in 750 grams of refrigerant but the compressor is still actuating on and off so its still not getting cold. The mechanic said there were no leaks so Im kind of at a dead end at the moment. I dont think its the blend motor because the AC was...
  10. AC Blows Cool Air (but not cold) , ML320

    W163 M-Class
    My AC stopped working suddenly this morning. The compressor is spinning on and off but the pipe is not cold and the auxiliary fans are not kicking on so it would seem to be low refrigerant pressure that is causing the problem. I plan on sending the truck to a shop with an evacuation unit but is...
  11. Tailgate will not unlock

    W163 M-Class
    My tailgate will lock using the power lock button but once it's locked it will not unlock so I cannot open the tailgate. It wont even unlock by sliding the switch on the inside of the tailgate manually. I assume this means that I need a new locking motor but I don't see how it comes out...
  12. Rear Strut Assembly - Sachs 033075?

    W163 M-Class
    Just curious, what are you planning on doing to your suspension? I have to do my springs and I'm wondering if there is anything else I should do while I'm under there.
  13. Rear Strut Assembly - Sachs 033075?

    W163 M-Class
    Art, I use my truck to pull a boat. Its about a 2,500 lbs. Would you recommend Sachs, Bilstein or OEM?
  14. Rear Strut Assembly - Sachs 033075?

    W163 M-Class
    How are the Sachs struts working out? I'm looking at buying a pair of them and having an indie shop do the job. The underside of my truck is pretty rusty so Im afraid I'll strip the three nuts at the top. Parts.com has the OEM assembly for 320 now BTW.
  15. Rear shock and strut assembly

    W163 M-Class
    What are the best aftermarket replacements? The OEM strut assemblies are pricy so I'm looking at options but I also need them to be good quality because I use the truck to trailer my boat around.
  16. Rear shock and strut assembly

    W163 M-Class
    Where can one find the OEM strut assembly with springs for $235 shipped? I realize this is an old thread but im not finding them for less than 350 or so.
  17. Thinking about buying

    W164 M-Class
    Hi Guys, Boston winters have finally rusted out my 99 ML320 to the point that I don't want to keep spending money on parts to keep her going. Love the truck but its just a real rust bucket at this point. I'm looking at a couple options. Find a southern W163 to replace it or move up to a...
  18. Power Steering Noise 99 ML320

    W163 M-Class
    Thanks, great idea. I will try that if I can figure out the size. I will add that I do not feel any play or resistance in any of the pulleys when I turn them by hand. The reason I think the noise is coming from the PS pump is that I can 'feel' the noise when I put my hand on it while the...
  19. Power Steering Noise 99 ML320

    W163 M-Class
    Heres a picture.
  20. Power Steering Noise 99 ML320

    W163 M-Class
    I pulled the belt off today to see if I could turn all of the pulleys and found the idler pulley had completely cracked and broken off the front edge. I need a replacement for it now. Any suggestions for what I should buy?
