i think only reason , when it happened mixed before in engine cooler he not flushing his rad and enginebut certainly worth looking for other causes.
that is mean oil residue and it collected in expansion tank

i like this way, but you have video how to drain and refillDrain the coolant. Flush the system through with clean water until the water coming out is completely clean. This may take a long while. You need to get all the old coolant out of the heater matrix as well as the engine.
Refill with new coolant but be very careful to follow the correct procedure in RAVE to fill and get rid of airlocks. The V6 will die quickly if there is not correct coolant flow or there is air in the cylinder waterways.
Can you tell me how to drain all coolant?The oil cooler has been known to fail, filling the coolant with oil. This can be the very devil to remove completely. I've done best by breaking the oil down with washing up liquid. This needed running up to temperature then draining out the bottom hose while it's still hot. I had to repeat the process 3 times before all the oil had gone.
I've not found a commercial product that does a better job really.

Because I tried before but I can't.
This photo usefulRemove the bottom radiator hose. This will get 50% of the coolant out. Then you need to remove the block drain plug, under the front exhaust manifold for the next 25%. The last 25% is trapped in the heater, engine oil cooler, gearbox cooler and IRD cooler. Just make sure the coolant is completely refilled before running the engine.
I've heard dishwasher soap is good for cleaning coolant systems. Makes sense as it is designed to flow through dishwasher plumbing and not foam. Just make sure it is properly dissolved if using powder.The oil cooler has been known to fail, filling the coolant with oil. This can be the very devil to remove completely.

that mean must open the tank, let engine rungiving the impression of bubbles coming out the coolant
that mean must open the tank, let engine run
Ok,i get your ideaNo, that's not necessary. Just make sure that there is always plenty of coolant in the tank. As the air bubbles out, it will take water from the tank to replace it. It can take several days driving to fully remove all the air in the system. This means regular coolant checks are vital after cooling system work.
