If your removing the knock sensors to drain coolant theres no point. Its next to impossible to remove without a hoist and isnt worth it for the extra litre you get out if that. You would be better to spray compressed air down and try and blow the rest of it out, alot easier.
You get more like 6 litres out. Ever wondered why when you drop the bottom hose and fill up, only 5 litres goes back in ? Its a 12 litre system, there is heaps left in, flushing with a hose dilutes it to near pure. Knock sensors are behind the sump, the part where the sump bulges out.
