m6 convertible oil temp gauge bouncing

• 2022-05-25

For M6,the oil temp gauge is also as water temp gauge,why is bouncing.

The indicator light of the preheating device is always on during preheating. The preheating time varies with the engine and cooling water temperature. When the glow plug is fully warmed up, the indicator light goes out, indicating that the engine can be started. If the preheating indicator flashes while driving, it indicates that there is a fault in the engine electronic control system. Check the engine immediately. If the ignition switch is in the on mode, the indicator lamp may not be on immediately. If the ignition switch is not in the on mode, check it.

Water temperature alarm lamp:

The water temperature fault light is displayed on the instrument panel, indicating that the engine water temperature is too high and there is a fault problem. The causes may be the lack of water in the water tank, the failure of the water temperature sensor and the failure of the water circulating cooling system. You should stop for inspection at this moment, otherwise you may damage the engine.

The reason why the Haval H6 water temperature gauge shakes is that the water temperature sensor is faulty. The water temperature gauge shows the coolant temperature, which is convenient for the owner to understand the vehicle condition. When the water temperature of the vehicle is too high, the owner needs to stop and rest until the water temperature of the vehicle drops to the normal temperature, and then continue driving. The following are the reasons why the water temperature gauge does not move:

1. Open circuit of water temperature gauge power line; The electric heating coil of the water temperature gauge is burnt out;

2. The electric heating coil of the water temperature gauge sensor is burnt out or the contact is poor;

3. Poor wiring or open circuit of water temperature gauge sensor wire;

4. The voltage regulator supplying stable power to the water temperature gauge circuit is damaged.

How:

Leakage or lack of coolant will cause the engine water temperature to rise. At this time, check the condition of the coolant. If it is insufficient, first add it to the appropriate position, and then check whether the liquid level drops seriously in a few days. If so, locate the leak. If the cooling fan fails and the heat generated when the vehicle is driving at high speed cannot be transferred to the antifreeze in time, the cooling will be affected and the antifreeze temperature will rise. Cause boiling and other problems. The water pump has several faults, such as locked bearing and damaged impeller. Bearing locking is rare. Impeller damage is common, such as impeller cracking or impeller loosening from the pump shaft, which will slow down the circulation speed of coolant and easily lead to engine overheating.
