« on: 23 January 2010, 15:26 »
rght, i attmpted to flush my cooling system on my mk3 gti, i removed the bottom radiotor pipe from the engine and let the coolant run out. then i re attatched the hose and filled the expantion tank with water and flush. ran it with the heaters on full then drained. but now i can only get two cup fulls of new coolant in?

i did mine while it was running and waited till the water started coming through then pushed it back on and just moving the pipe slightly while its on so a bit of water seeps out mine were cold but after ive done that theyve never been so good im sure theres an easier way though
