Intercooler bleeding tool (final version)
one side give the highest vacuum you can get on the market
maybe I can use the other side to get coolant in, I will see
you don't need this big expensive device of course, it's just because i'm sick and like beta testing lol
but that is because I interconnect a 100L buffer
this should do the Job better
but if you removed the radiator and so, I don't think that it will auto bleed that amount of air.
but I can't confirm
maybe you give WIS a try on that amg 65 with overflow tank.. see what they say there, I didn't look yet
I am building my super bleeding tool with 12L looped tank, no more fill empty ****
The Best of Mercedes & AMG
Well, as usual, Nick was right about perfect vacuum
With a -27-30 100% vacuum bubble delete is super fast
I do not have improvements as I always bleed until no bubbles
but the Spal fans do miracles
I think that I done bleeding correctly right now by vacum tool from thread instructions.
Your tool works perfect and after testing all methodes found on forum I can confirm that this is only one way to do bleeding correctly.
Yes- you can do it without tool but your intake cooling system never will be fully efficient.
I made about 35L circle, now without maybach mods, still waiting for ordered parts.
It's important to leave coolant fill system after disconnect tool for night, after few hours it will get about 100ml coolant.
Thanks a lot for informations Pmercury

Now my intake temps:
SL65 AMG
Air temp: 20'C.
In city traffic ( Before: 90-100'C, after: 65-75'C )
Speed about 80 km/h ( Before: 60-70'C , after: 40-50'C )
Speed about 140 km/h ( Before: 65-75'C , after: 34-55'C )
After leave a car after ride for example 30 min stay, temp get 80'C. Car need about 400-500m ride to get 50'C.
It's need only put a little pedas gas to drop down intake temp.
My car hasn't any heat mods, I will install 2x front additional exchanger like in black series and secound water pump.
When I do it and test I will leaving information for us how my temps looks.

In city traffic ( temp ? )
Speed about 80 km/h (temp ? )
Speed about 140 km/h ( temp ? )
Also I have a question. Standard Bosh pump are engaged when we put a little gas pedal. I saw that car drop temp on P-gear when add some RPM. Does the pump increase its flow as the engine rpm increases or does it always work the same ? I am asking becouse still thinking about make connection to relay that pump work all time after key.

you might freak out, I will
the bosch pump has alway one speed, just ON / OFF
it is not the IC pump who drops temp
it's the engine mecanic coolant pump who does that, I noticed that too
I need to test if the Xentry Das setting for raising the idle RPM of the engine is enough, not sure
you can find that here

In city traffic ( now: 68-75'C )
Speed about 80 km/h ( now: 50-60'C)
Speed about 140 km/h ( now: 45-60'C )
I saw that the problem come back after one quick run without ESP in city- somethink like burnout with rpm rev.
Maybe coolant system cap does not keep the pressure under a high load. I am still waiting for maybach parts and hope it will solve problem definitely.
My question:
When we do bleeding and after all leave car connected only to fresh coolant like you wrote after night I saw that it drew about 100-200 ml coolant fluid more.
It is correct ? I am asking becouse one day after that I saw small spot of coolant under the car. This fluid has leaked through the vent behind the liquid filler cap.

with a 30c outside you will have higher temps then with a 24c
Also 20 min ago with 12'5C outside temp at 80 km/h is about 55-60'C.
It's to high I think.
MrPmercury do you have information about power drops depending on the intake temperature ?

2. Bleeding done again.
3. Temps in normal driving about 35-45'C so I think it work correctly.
4. Will see in next days coolant level

5. After 30 km leave a car for 30 min and it get about 91'C Air temp ( is it normal ? )
Start driving again and it come back to normal after 1-2 km. Intercoolers are really cold

but these 3 parts are not Maybach specific at all

A2792000185 Tank
A2790980891 rear metal line to tank
A2790980283 rear rubber hose

sure do
but read these 2 pdf's first, you might understand the v12 better

Yours looks a lot like by OEMTOOLS for 74.60 with 4.8 stars on 22 reviews. I'm gonna have to get me one!
