In 2000, Fukang 1.4 displacement neutral hot car appeared idle speed as high as 3000 and then boiled?

But add one thing.

If the idle speed is abnormal, the usual way is to clean the throttle.

Idle valve

Follow-up air pressure sensor vacuum tube

(Note

The throttle needs to be initialized after cleaning the throttle)

If the water temperature is high, look at the cooling circulation system.

Whether there is air resistance (that is, when antifreeze is added, the air inside is not exhausted, resulting in excessive local temperature)

Or the electronic fan does not work, resulting in abnormal heat dissipation) (check the brown water temperature sensor.

Open the key

Unplug the brown water temperature sensor.

The electronic fan should turn.

If the plug of Brown water temperature sensor is replaced

If not, check the electronic fan relay and water temperature control box. High water temperature does great damage to the engine.

Pull the cylinder easily

Cylinder washing bed

High water temperature and high water tank pressure

It will push the water tank cover to release the pressure, resulting in the coolant flowing out of the water tank drain pipe.
