ok. I gave it a go. didn't work. could be because my engine was not on the normal operating temp. when i start engine the temperature indicate low.
Am I suppose to leave the engine on in order to increase the temperature? I mean at current situation it seems pretty hazardous as the throttle/accelerator is always on. and the tachometer read 3/4! it makes loud noise. i didn't dare to keep it on for more then few seconds.

I see little different procedure than the youtube video
