My car is smoking and a light is flashing

The flashing light on your dash is telling you your engine is running too hot. What do you mean by smoking? From the engine compartment or through the exhaust pipe? If through the exhaust pipe and the smoke is white then I would say your head gasket is going bad. if it is smoking from the engine compartment, then you have a coolant leak from a hose, radiator, water pump and you are probably low on coolant causing the engine to overheat.

Good Luck

STOP driving the car until ALL of the following are done...
1. Flush the cooling system... ask here if you need directions.
2. Replace the thermostat ... again, ask here if you need help.
3. Add 150,000 mile antifreeze (FULL STRENGTH ONLY....) 1 gallon... and then top off with water...

Your total costs should not exceed 15 dollars US... if you purchase at walmart and do the work yourself..

Your car is overheating. turn it off and let it cool down. remove the radiator cap with caution make sure it is cool first. refill your car with antifreeze and check all your belts and hoses. make sure you dont have any leaks from hoses, radiator, water pump, if you dont see any leaks refill with antifreeze then make sure the cooling fan works.
