If you refill the coolant 2 times per week, there is a problem. Is the vehicle overheating? Have you checked for coolant leaks? Have you checked to see if there is coolant mixing with the engine oil? Is there excessive white smoke from the exhaust?
As far as the fan relay, you can't tell if it is bad by just looking at it. Switch it with a known good relay from the relay box that has the same part number.
