My car has engine knocking. When it's cold early in the morning warming up, it's fine. Aftr 15-25mins of driving and then stop at road, at idle, aftr 1minutes it knocks. I already cleaned my radiator on radiator shop, it improves not unlike before na it always knocks even early in the morning. I think, the water cannot cirulate well in engine that's why it knocks. What do u think? And wat do i need to do?
