When I start the car I can see a little white smoke coming from the left lower side of my engine. I lost a lot of coolant
My car has an automatic transmission.
The smoke is from the coolant leak when it hits a hot exhaust manifold. The leak may be from the thermostat housing. You should have the cooling system pressure tested to verify the leak in the system at the thermostat housing seal. Also you may want to verify the water pump is not leaking.
