engine overheating light · temperature warning light · red thermometer light
The engine coolant temperature has climbed above the safe operating range - the engine is overheating.
Turn off the AC, turn on the heater to pull heat away from the engine, and pull over as soon as safely possible. Let the engine cool for at least 20-30 minutes before opening the coolant reservoir cap (never open a hot radiator cap).
No. Continuing to drive an overheating engine can warp the cylinder head or blow the head gasket within minutes, turning a cheap fix into a very expensive one.
