Expert Hi,
Other than the parts checked , Overheating seems to be due to scale formation which occurs due to prolonged usage and also type of water mixed with coolant. solution is to get overhauling of engine. With long usgae the efficiency of engine surely comes down due to wear and tear, scaling etc. Hence recommended to get overhauling if overheating is beyond the bearable limits.
