Engine flush problem
 

Hi all I'm struggling to empty my boxster of coolant. I followed the pelican book to the t. I also watched road and race and a few other videos on the subject. I managed to fill 3, 5litre Containers and that's it. I lifted the front of the car up and lowered the back and vice versa. But that's all I can get. All hoses are off. Any ideas chaps thanks.
