Rusty Sediment In Radiator Water

[NISSAN GTR]

I have read every topic in relation but with little help, anyway here goes i tried to flush my radiator first with a hose flowing from the top of the radiator out through the radiator cock , then used about 30 litres of demineralised water to flush driving the car for about 40 mins also turned the heater on for about 15 mins over 8 seperate occasions but still getting dirty rust sediment water almost as bad as the first flush ?

WTF.............. Is the stock GTR R32 radiator copper core , aluminium core or steel core .

I dont know whether the rust is coming from the radiator , heater core or block whats the way to go any ideas ? cheers

copper core , aluminium core or metal core

copper and ally are both metals mate

rust is probably coming from thermostat housings, radiator core or the heater assembly, its impossible to tell where its coming from!

block most likely....everyone I've ever looked at has a little rust in the galleries.
