[Notes of Spring and Summer] Pay attention to cars to prevent high temperatures in vehicles

September 4, 2024

The main reasons for high temperatures in cars include:
Thermostat failure. The thermostat is an important component for controlling the circulation of engine cooling water. If the thermostat fails to work normally, it will cause poor circulation of coolant inside the engine and affect the heat dissipation effect.
Insufficient coolant or improper use. Lack of antifreeze or using water instead of antifreeze can lead to poor engine heat dissipation. Long-term use of water as a cooling medium may also cause scale accumulation and blockage of waterways.
The water pump failed. Damage to the water pump or slipping of its belt will cause the water pump to work poorly and affect the circulation of coolant.
Cooling fan failed. The cooling fan cannot work properly or is inefficient, which will affect the heat dissipation effect of the engine.
Failure of shutter or radiator. The louvers cannot be fully opened or the radiator is dirty or damaged will affect the heat dissipation effect.
Engine cylinder gasket cracked. May cause antifreeze leakage and affect the normal operation of the cooling system.
The cooling system is blocked. Problems such as fouling in water jackets and water distribution pipes and clogging in water tanks can cause poor flow of coolant.
In addition, there may be reasons such as improper ignition time, too thin or rich mixture, and too tight or loose valve clearance. To deal with the problem of high temperatures in automobiles, we need to comprehensively consider these factors and carry out corresponding inspections and repairs.

When Mo’s version of the car was driving on a road trip, he found that the cooling fan had intermittent starting noises, which might lose control and damage the water tank. When he returned from the car, he immediately arranged for surgery!

The gap behind the water tank of this Geely Boyue car is not large. Some people say that the fan must be replaced before it can be replaced, while some people say that it can be replaced without removing it.

It’s a bit insufficient to visually check the position, but the key is that they are all plastic parts, which are somewhat elastic. With a little force, they will deform. It really took no time or effort. Two screws were unscrewed at the top and bottom. It only took a few minutes to pull them out, saving at least a few hours. However, when disassembling, he found that the buckle was only 3 mm away from coming out. Mo Ban decisively asked the master to cut it, but it was useless anyway.

During the dismantling process, it was also found that this tee was leaking, and it was decisively replaced. Therefore, it is said that the engine cabin cover is too tight and is not conducive to daily inspection.
