Default Re: Radiator Overheating

Saved plugged radiators by back flushing with an industrial hot water pressure washer using chemical degreaser.The best way to insure a repair is to remove the radiator and cylinder head,clean the water jacket,(i use compressed air and a speedometer cable on a drill motor to snake the passages).iv gotten twigs,rocks and all kinds of grunge from water pump grease rust and dirt coagulating..chemical flushing like you are doing is fine,and if it works,great...if it doesnt you need to go deeper
