Fix the problem of car engine being difficult to start in cold weather

The phenomenon of cars being difficult to start when the temperature drops is no longer too strange to drivers. However, to overcome this problem, it is necessary to find out the exact cause to have effective treatment measures.

Reason

There are many reasons why cars are difficult to start in the cold winter. First of all, fuel is the first cause. Like other liquids, gasoline evaporates less in cold weather, making the combustion process difficult.

In addition, when the air temperature drops too low, the oil in the tank shows signs of solidification, precipitating on the surface. This causes the car's oil filter to be clogged, hindering the transmission of fuel into the combustion chamber, making starting the car more difficult than usual.

In addition to gasoline and lubricants, batteries are also susceptible to the effects of cold weather. Specifically, chemical reactions inside the battery will take place more slowly when it is cold. Therefore, starting the engine will also take place more slowly because there is less energy.

So how to fix this phenomenon? Here are some effective remedies you should try in this case.

Turn on the ignition several times to heat the air.

First, when starting the engine, you need to turn off all fuel-consuming devices such as fans, air conditioners, radios, lights, etc. Then turn on the ignition and leave it in the ON position, wait until the heating indicator light turns off. Do this about 5-6 times before starting, so the engine will start easier. After the engine has started, do not step on the gas immediately, let it idle for a while, then slowly step on the gas and start.

Press the hand pump to circulate the oil better.

The round knob located right above the fuel filter is the hand pump. Before starting, to help push the oil into the high pressure pump and the oil can circulate better, the driver needs to continuously press the hand pump, press until the hand feels tense and can not press anymore, then stop and try to start.

Fuel heating in the high pressure pump

If the weather is too cold that your car can not start, you should use a fan heater or slowly pour boiling water into the fuel filter and high-pressure pump area. With this method of fixing a car that is difficult to start in the winter, the temperature of the fuel is pushed up and makes it easier to circulate. This is a simple and effective way that you should use.

Heat the bottom of the crankcase

To make the engine lubricating oil less thick, the driver needs to use a blowtorch or light a fire directly at the bottom of the crankcase. With this method, it is important to note that the clutch is pressed so that the gearbox oil does not hinder the engine's rotation. This way, the engine will start easier. However, you should consider before using this method because although it is relatively simple and highly effective, it is quite dangerous.

Use backup batteries

If the reason your car is hard to start is due to a weak battery, you should jump start it by using a spare battery. If you want to use the battery for a long time, when the engine is hard to start, you should not start it continuously because if you do so, the battery will quickly lose voltage and lead to damage.
