Answer 1
It could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say. It could be a weak fan clutch, a thermostat that is not fully opening, a restricted radiator (not allowing coolant to circulate through all the cooling tubs of the radiator) or even the possibility of a mildly blown head gasket. Hard to tell without being able to do some basic tests. -

thanks Patrick! I will do that right away... -
Answer 2
Patrick hit the nail on the head. I would recommend having your vehicle diagnosed sooner rather than later to avoid damaging any other components. -
