How is the engine hot

summary

The engine overheating causes certain damage to the engine. In summer, when the air conditioner is on, the working load of the engine is aggravated, and the temperature rises sharply. Let me tell you something about a hot engine.

How is the engine hot

First: fan problem, fan motor does not move or fan clutch failure, unable to cool normally. The blockage of three-way catalytic converter or the rupture of pipe cause the exhaust blocked and the engine overheated.

Second, if the pipes of the cooling system are broken, the coolant will be lost and the heat dissipation will not work normally. This situation can be improved by changing a new pipe. The only solution is to replace the pump with a new one.

Third: if the pressure of the radiator cover is different, the spring will be loose and the cover opening cannot be closed tightly. Too much oil supply, too little oil or poor lubrication. Poor heat dissipation is caused by poor combustion, improper ignition or valve timing, oil sludge in the engine shell, etc. in case of water cooling, it is necessary to check whether the coolant is sufficient, whether it circulates normally, or if it works continuously for a long time.

matters needing attention

The thermostat can not be opened and closed normally, which is usually caused by mechanical failure or incomplete filling of cooling system. The new thermostat is different from the original temperature coefficient, which causes the failure.
