What is engine overcooling?
Engine overcooling is the lowering of the temperature of the engine below the optimum temperature required for the proper combustion. As like overheating, overcooling is also harmful to the engine life and performance.
The overcooling of the engines has various effects on the engine.
Symptoms of engine overcooling:
The symptoms of engine overcooling are as follows:-
1] The temperature is not enough for the proper combustion of fuel. Hence this improper combustion results in the formation of carbon deposits.
2] It lowers the fuel economy and also reduces the overall efficiency of the engine.
3] It also causes difficulty in starting the engine.
4] Because of the generation of carbon deposits the life of lubrication oil also lowered.
5] It causes condensation in exhaust pipes which accelerate the rusting.
6] Increase in consumption of fuel.
7] Increase in wearing of the cylinder.
Causes of engine overcooling:
Here are some reasons because of which the engine may experience the effects of engine overcooling.
1] Improper working of heater during the cold season:- During the winter season, if the heater is not working properly then the engine runs with the effects of overcooling.
2] Thermostat is not working properly:- If the thermostat starts the cooling too earlier or if the thermostat is continuously kept cooling on then the engine becomes overcooled.
3] If the bypass valve remains open:- If the bypass valve of the radiator is open then the coolant will continuously circulate through the circuit and that causes the overcooling of the engine.
