Please I need help on my VR6 golf. My vr6 had been experiencing a re-ocurring radiator problem. The water in the radiator gets dried up very often say every 30 miniutes drive. I had replaced the radiator with a new one, replace the head gasket and water pump and also ensure that none of the radiator water hose is licking, yet the problem still persist . what do I need to do to solve this radiator problem. Please help.
