Thick white smoke from exhaust, change thermostat, fan doesn't come on, top hose stays cold, opened radiator cap and saw coolant get lower. some white smoke or something similar comes off the exhaust manifold pipes.. temperature gauge in car is not moving from cold. I did remove some coolant from radiator to remove the thermostat but problem was happening before I change the thermostat. any help would be great.
