If the temperature is going above normal, don't drive the vehicle. Get it to a shop as soon as possible, you risk causing severe damage to the engine if you run it low on coolant or overheat it.

the light flashes for 3 reasons: 1) coolant level low...check for leaks 2) car overheating...don't drive, may cause damage 3) plug under reservoir unplugged or wires damaged...repair as needed.
