Can be caused by: low coolant level, bad thermostat, bad/weak water pump, blockage or no flow in radiator. Look for leaks, collapsed hoses. After inspecting hoses, try replacing thermostat and adding new coolant.

HEATER CORE CAN BE BLOCKED AS WELL. IF YOU STILL HAVE ORANGE COOLANT GET RID OF IT AND PUT IN GREEN. ONCE YOUR BLOCKAGES ARE CLEANED YOU WON'T HAVE ANYMORE TROUBLE.
