The car engine converts chemical energy to mechanical and heat energy, most of the  heat dissipated must be transferred out of the system to keep it in a good working condition.  The car engine use the radiator which in turn uses the electric fan and thermosyphon method to cool its system. For a car to overheat that means the car has a problem either with water circulation or an electric fan issue. CAUSES OF OVERHEATING 1. Low coolant; The coolant level might be low due to leaky hose. To stop overheating the coolant level must be between the minimum level and the maximum level in the reservoir. Also check the radiator for leaks  2. Faulty thermostat; The thermostat is located in the engine, it helps regulate the flow of coolant into the engine block. 3. Faulty electric fan; The fan helps to cool the coolant in the radiator. 4. Clog in the radiator and engine; this clog is caused by minerals in the water. They tend to block the water ways there...

Check the colour of the smoke being emitted by the engine. a. Blue smoke; blue smoke implies the engine oil is entering into the combustion chamber. b. Black smoke; This implies that the fuel entering into the combustion chamber is too much and there is incomplete combustion of fuel in the engine. c. White smoke; This implies that coolant is entering the combustion chamber. The white smoke is actually steam. Take note; Its normal to see a white smoke when you turn on your engine in the morning. 2. Check the oil to see if it is contaminated by water or fuel. smell it to check if it has a hard fuel smell , if it do...
