I am appending below Rob's DIY for Brake and Rotor Replacement.. Nice job Rob..!!

'98 Brake and Rotor Replacement DIY

--------------------------------------------------------------------------------

Hey Everyone,

First off I wanted to thank everyone on here for such valuable information. After sorting through all the pictures taken during the install, I made a simple webpage going through the process step by step to help change the pads and rotors. I don't claim it's perfect, but atleast it can offer more insight to someone who is looking for pictures or more info on how to replace their rotors and pads.

It's been about 3-4 weeks now, and everything worked out great. If there are any suggestions or comments, feel free to let me know as well.

Thanks again,


Brake and Rotor Replacement

DIY Coolant Flush 2001 ML320

So after searching everywhere for a DIY and finding nothing I decided to write my own, so here we go.

Things you will need:

2x 1 Gallon MB Coolant Containers PN Q1 03 0002 (Local Dealer $40)
3x 1 Gallon Distilled Water (Walmart $2)
1x Antifreeze Funnel (Autozone $3)
2x Auto Ramps (Optional, Makes Job Easier Autozone $35)
1x 19mm Socket and Wrench (Or Needle Nose Pliers and Strong Fingers)
1x 5 Gallon Bucket Clear W/ Quart Marks (Optional, You Need a Large Container That Can Hold At Least 5 Gallons.

Time to complete: 30-45 Minutes

First we need to drain the existing coolant from the radiator, in order to do this we must loosen the black radiator drain plug. This plug is black and has a fin to turn it by, it is located on the bottom/front passenger side of the radiator as shown in the below pictures. It can be seen through the bumpers bolt opening with a flashlight and very hard to get to.




In the second picture it is the square looking thing to the right, turn to the left a couple times and coolant will start to pour out of the hole shown below.



Make sure you have a container under the drain hole and turn the plug on the radiator.



It was pretty tight so I worked a 19mm Socket up in and onto the drain plug fin.



Wrench up under bumper.



It fit great and allowed be to tighten and loosen as needed. You will want to open the filler cap on the expansion tank to allow for the coolant to flow as fast as possible.



You will want to drain all of the coolant out and it will drain 2 gallons 8 quarts total.



Once all of the coolant has drained pour one of the distilled water containers you bought into the expansion tank and let it drain through. It should be clean at this point and no longer yellow. Once this is done tighten back down the radiator drain plug. Now we will fill the system with new coolant, MB recommends that you mix coolant in a 50/50 mixture. In order to do this pour half of one of your MB coolant containers into your now empty water container and then fill the now half empty container with distilled water.
Shake the MB coolant container well to mix the contents equally.
Put the funnel in the expansion tank and pour the contents slowly into the funnel.



It will bubble and take the first gallon, you then must do the last couple steps and pour another gallon into the expansion tank.
Squeezing the top radiator hose will allow for the coolant to settle and get rid of all the air to take all two gallons.



At this point you will cap the expansion tank and turn on the car. You will want to turn on the heater full blast, turn off the air/con and let the car warm up. Once the car is warm rev the engine to allow for the heater coolant to flow properly.
After about 10 minutes you will want to do the flush we just did again to remove any of the coolant that was in the engine block and heater pipes. This may seem overkill but it is worth it in the end. Hope this helps some people with a coolant flush.

Huniyi genleşme deposuna koyun ve içindekileri yavaşça huniye dökün.



Kabarcıklı olacak ve ilk galonu alacak, daha sonra son birkaç adımı yapmalı ve genleşme tankına başka bir galon dökmelisiniz.
Üst radyatör hortumunun sıkılması, soğutucunun yerleşmesini ve iki galonun tamamını almak için tüm havadan kurtulmasını sağlayacaktır.



Bu noktada genleşme deposunu kapatacak ve arabayı açacaksınız. Isıtıcı tam patlamasını açmak, havayı / con'u kapatmak ve arabanın ısınmasına izin vermek isteyeceksiniz. Otomobil ısındıktan sonra, ısıtıcı soğutma suyunun düzgün bir şekilde akmasını sağlamak için motoru devirin.
Yaklaşık 10 dakika sonra, motor bloğunda ve ısıtıcı borularında bulunan herhangi bir soğutucuyu çıkarmak için tekrar yaptığımız sifonu yapmak isteyeceksiniz. Bu aşırıya kaçmış gibi görünebilir ama sonunda buna değer. Umarım bu, bir soğutma sıvısı olan bazı insanlara yardımcı olur.
[/ALINTI]Aferin sana.

Alternator Change/Upgrade

I can confirm that an ML430 Alternator Will fit on a 98 ML320
Old Alternator 115 amps
New Alternator 150 amps (woot)


DISCONNECT THE BATTERY!!!
DISCONNECT THE BATTERY!!!
DISCONNECT THE BATTERY!!!

this time its for real i usually dont bother on other projects but you are about to unscrew the POS pole of your battery from your alternator and inherently your ratchet will touch the gasket causing massive spark inferno possibly melting a whole in it!


1.) remove air filter housing (black box)
2.) remove fan shroud and fan
3.) remove serpentine belt
4.) unscrew the two big bolts holding the alternator in place
5.) give it a little knock downwards (might need a hammer after 10 years this thing wasnt going to go easy!
6.) now that its easy to turn the alternator take of the two (2) cables in the back
7.) put new alternator in place (dont screw it in yet) and reconnect cables
8.) put bolts back in and reassemble in reverse.

NOTES:
fan shroud can be tricky, be patient as the radiator is easily damaged by the corners of the shroud.
doing this on a "cool" car is much easier...!

i know this isn't very detailed but don't hesitate to ask if u need more info!




the hiding bolt

these two need to come out!

disconnect cables:
Imageshack - dscn3039q
two attachments points

pats that come off (nuts from alternator cable attachment points not included)


150 amps...


blurry MEH!

BOOM BOOM POW!

DYI - central lock remote control encoding

Hello Everybody,

As in the title - below you will find the instruction to encode your central lock remote control, e.g. after replacement of batteries in remote. The instruction works with both EU and US spec ML's made after 09.2001 (facelift versions).

FYI - the remote control uses 2 CR 2025 (3volts) batteries :)

-turn ignition switch to position II
-turn ignition switch to position 0 and remove key
-within 1 minute:
-press and hold key lock button
-press unlock button 5 times
-remote control should now operate system
-if not: repeat procedure

Regards,
LUK_KRK

This is a DIY I found from Enrike detailing the Crankshaft Position Sensor replacement on an ML320 V6

Crankshaft Position Sensor DIY - MBWorld.org Forums

When ordering the Crankshaft Position Sensor for an ML230 you need to know the ENGINE NUMBER (which is not the VIN).
The engine number location is shown in your vehicle manual, but good luck finding it. It is actually stamped in a very awkward location on the edge the block, very hard to see without removing some parts. The stamped numbers are about 30cm right under the Coolant Reservoir and you need a flashlight in a 45º angle very close the motor number. The stamped numbers are little dots. The picture from the link below shows the stamped motor number 5 times better than you will get to see it in reality. The motor number looks like that 112942 xx xxxxxx.
I didn't remove any parts though, but is not easy ...
