How do you bleed the air out of the cooling system on a 2001 mercedes s600 with the v12 motor

If a valve is expose on the upper heater hose piping crack that open only when the engine is warmed up for at least 15 minutes. If no valve is seen you will need to loosen one of the heater hose clamps ever so slowly to let the air out. The process to loosen the clamp is not recommended unless you do this first..... When the engine is COLD loosen a hose clamp and remove the hose and put it back on. Thighten the hose clamp snug only. The start the engine to warm up. In about three minutes see if you can twist the hose to move on the fitting. If you can snug the clamo a lttle more and check again. You do not want the hose to come off if too loose. Now that the engine is warmed up for 10 to 15 minutes shut OFF the engine and barely loosen the same clamp 1/4 turn at a time until coolant trickles out. Listen carefully for air escaping too. Air pressure does built up only when the engine gets hot and the air pocket does not move when the engine was cold with the hose removed beforehand. If no air was released upon this proceedure you have a blockage in your system and flushing maybe the only other option using pressure instead forcing the coolant out. Get a can of coolant flush before the power flush proceedure. A radiator pressure tester can be used to power flush with an air fitting adapter installed in place of the guage

Hi,

Which parts of the engine are you wanting to look at.

Let me know an I can give you more information.

Thanks

SOURCE: need to know the waring

The 2001 Mercedes s600 mounts 4 standard 4 wires oxygen sensor.

The color code of the wiring may change depending on the brand of the sensors mounted. Mercedes mounts by factory Bosch sensors.

Here the original color codes for factory sensors:

SIGNAL : Black
GROUND : Gray
HEATER (Ignition switched +12) : White
HEATER (Gnd) :White

The most important wire for testing purpose is Signal, this determines the sensors' output.
If colors are different, simply found out ground wire with a multimeter, the two heater wires have usually same color code.
If you are re-wiring, the heater contacts can be exchanged, the heater works the same in both ways.


In case the car is mounting a different sensor, here wiring diagram for sensors from different manufacturer. If this satisfies the query, please do not forget to accept the solution.

It should bleed out by itself as there is an overflow tank mounted under the hood. This tank (plastic Usually), is an expansion tank that allows the hot fluid to force itself into this expansion/overflow tank, allowing the air to escape. If this tank is not about half full (there is a fill line marked on it), when you end driving. The fluid when it gets cold will be sucked back into the radiator, then you need to add fluid to the cold fill line after it cools down. If the vehicle is over heating then your pressure cap may be kaput or your radiator is being blocked or cooling fans not operating.
