Suggest a leak in the header tank area. Had a similar problem with a Surf. Put a new radiator cap on. No more loss of coolant.
Pressurised system, coolant in radiator expands when hot, goes into header tank. Tank overflows, pushing coolant onto road.When cooling down, coolant should be sucked back to radiator. If a slight leak in system, no suction, coolant does not return. Think you should have it checked by radiator specialists.
