last week i noticed my car starting to over heat and the antifreeze and water were a brown colour in the rad. i got some advice of a chap of here and removed the thermostat to see if this worked this seemed to work fine no overheating was happening. Then i decided to flush the coolant system as i was told the liquid in the radiator should not be this colour which i thought anyway i flushed out theradiator with some rad flush and repalced the coolant and water. the coolant was glyco-shell. i got all the air locks out and then went for a short drive and for some reason it started to over heat what could be the cause of this should i be using a different coolant thanks for any advice
