I was driving under normal conditions yesterday when all of a sudden i noticed the temp guage rising...HOLY SHIT! never seen that before... this was when i was at a light idling. Then, when i started driving and let off the gas it fell back down to normal. Then started goin up again. Parked and turned it off and popped the hood to find coolant sprays all toward the front of the engine bay and a bunch of coolant sitting at the bottom. I have no idea what to do or really look for. There was very little coolant in the radiator and its really low in the resevoir. Any hints before i take it in to get looked at?
