today, i was driving my car over a hill to school. the WHOLE WAY no warm air came out of my heater. and i check my gague and it was almost maxed out. first thought was no radiator fluid but i turned it off and coasted, little later its at normal again... then it spikes back up to max, and fluctuated a little from then on... messed up! what is wrong with my car??????????
