Causes and ways to prevent car engine overheating

* Causes of car engine overheating

Fan failure: The fan helps increase the speed of air circulation through the radiator to increase cooling efficiency. If the fan is broken, the cooling efficiency will decrease, causing the water to boil and the engine to overheat. The radiator is too dirty. If not cleaned regularly, the radiator will be clogged, leading to limited heat dissipation.

Inefficient water pump: The water pump in the cooling system is responsible for circulating water in the cooling system with a certain pressure and flow. For some reason, if the water pump does not work effectively, the water flow and pressure in the cooling system will not be guaranteed and cause the engine to overheat.

Engine adjustment not according to specifications:Vehicles using carburetors, if the ignition timing and air mixture ratio are not adjusted correctly according to technical requirements for operating modes such as idling, accelerating, etc. of the vehicle, the mixture will be too rich or too lean. This will cause loss of engine power and lead to overheating.

Thermostat is stuck: The thermostat has the task of shortening the warm-up time, helping the engine save fuel and reduce wear. The thermostat is responsible for adjusting the amount of water passing through the radiator according to the coolant temperature. After a period of use, for some reason, the thermostat gets stuck and cannot open the water line through the radiator, causing the engine temperature to not dissipate.

Improper use and operation of the vehicle:Overloaded vehicles (when going uphill or encountering high ambient temperatures) often cause the cooling system to boil over. Improperly maintained lubrication systems such as lack of lubricant, aging lubricant, using the wrong type of lubricant… also cause the engine to overheat.

Cooling system failure:The task of the cooling system is extremely important, with the function of quickly transferring heat from the combustion gas to the cooling medium, helping the engine parts to work in an environment that meets the standards required by the vehicle manufacturer.

• Overload:Overloaded vehicles often cause the water in the cooling system to boil when climbing a hill. Pay attention to this cause because if the vehicle is overloaded, it will not only affect the cooling system but also cause damage to many other components.

*How to prevent engine overheating

Pay attention to the cooling system

Paying attention to the cooling system will help reduce or avoid the consequences and damage caused by incidents. To do that, you must first remember to do the following: Check the auxiliary water tank and radiator once a month, or after each long trip, to prevent leaks, and keep the radiator clean. To prevent corrosion and good cooling of the radiator,

Pay attention to check the water pipes

It is important to keep your hoses in good condition. Pay attention to the large hose near the radiator cap and the smaller hoses at the bottom of the radiator. If you notice any abnormalities such as cracks or swelling, replace the hoses.

Check coolant level every time you change engine oil.

At least once every two years, the old coolant should be drained and replaced with new coolant. Keeping the inside of the system clean helps prevent corrosion and scale build-up. Every time you have your oil changed, take your car to a garage for a quick check of the cooling system.
