check gauge warning indicator (low oil pressure/high coolant temp)

• 2023-04-04

Reasons for high coolant temperature:

1. Low coolant level, insufficient circulating water volume, or coolant leakage; 2. The radiator, cooling water jacket, and water distribution pipe are blocked, rusted, or have excessive fouling, resulting in a decrease in heat dissipation capacity; 3. The thermostat fails and cannot be opened normally, resulting in poor operation of the coolant circulation; 4. The electronic fan does not work due to a circuit or motor fault; 5. The water volume of the water pump is insufficient, the water pump drive belt is too loose or slipping, the water pump impeller is damaged, and the seal is poor; 6. The ignition time of the engine is too late, and the combustible mixture is too rich or too lean; 7. Excessive carbon deposition during combustion increases the compression ratio, resulting in deflagration or poor engine exhaust; 8. The cylinder gasket was washed out, allowing high-temperature gas to enter the cooling system.

The reasons for the low oil pressure of the car are: the wear of the oil pump, or the wear of the pressure limiting valve or foreign matter; the oil storage is small; the oil is dirty or sticky during driving for a long time; Gauge or circuit failure; oil sensor plug, pressure gauge or circuit failure, etc. Take the wear of the oil pump, or the wear of the pressure limiting valve or the presence of foreign matter and low oil storage, the solution is to lift the car, check along the pipeline, and then see where there is a problem, and repair and replace it in time; The solution to the small amount of storage is to buy a bottle of engine oil that is changed during maintenance and add it in. The problem of oil leakage and oil leakage can be found and solved.

When the low oil pressure warning light is on, stop the vehicle and turn off the engine immediately. Fire, restart the engine after checking and troubleshooting. No otherwise, it may cause a serious accident of engine burning. If you can't troubleshoot on the road, you should go to the repair shop help.

1. The coolant alarms, indicating that it needs to add coolant, if the water temperature reaches the red line above, you can't continue driving. If you can't add coolant temporarily, you can consider stopping and operating. To lower the water temperature, if the water temperature is normal, only the coolant indicator light will alarm, you can continue. Continue to drive, pay attention to the water temperature during driving, and replenish antifreeze in time when conditions permit. 2. When the temperature is high, if the concentration and height of the coolant are not within the normal range. In addition, when the coolant warning light is on, it is easy to cause engine failure or even "turn on" If it does not affect safety, please pull over immediately, turn off the engine as soon as possible, wait for the engine to cool down, and then open the front cover of the engine for inspection
