radiator on my S reg punto seems blocked?

remove the rad,if you think it is blocked dont take any chances,go to a scrappy and get another one,if you want to persevere get a hose into bottom hose and reverse flush it,put a coolant system cleaner in and run it for a day or two,drain and refill,when filling open bleeders if there are any to get rid of air locks,unlikely but have had water pump impellers sheared off or corroded resulting in poor circulation,good luck
