Hi there. From the description you have given, there are multiple concern that require diagnoses. Most importantly are why the engine has misfires and cooling fans inoperative. The misfiring cylinders and exhaust smoke could be caused by a head gasket problem, especially if, there is coolant loss. The cooling fans not working may have caused a head gasket problem. There are many steps that can confirm a head gasket problem, cooling system pressure test, combustion leakage test, compression test, etc....The concerns you have need to be addressed before you continue to drive your vehicle. I recommend having your vehicle inspected and diagnosed by a certified technician from YourMechanic.
