10 common truck breakdowns

Nov 08, 2023

1. Engine oil level check

2. Engine coolant level check

When the engine is hot, never open the radiator cap to avoid being scalded by splashing coolant or high-temperature steam. Wait for the engine to cool down before checking the coolant level. Ensure that the coolant level is between the "full" and "low" marks. If necessary, add distilled water or purified water, but ensure that the liquid level does not exceed the "full" mark. If you notice a rapid decrease in coolant level within a short period, check the cooling system for leaks.

3. Brake fluid level check

4. Check clutch master cylinder fluid level

Clutch fluid level between the high and low fluid mark is normal, if it is below the standard line, it may be the main pump or sub-pump seals damage. It will be difficult or impossible to shift, please go to the nearest service station immediately for repair.

5. Maintenance and inspection of batteries

If the vehicle is not started for a long time, you need to take off the positive and negative battery cables and rewire them about half a month apart to start the engine for about 20 minutes, and then recharge the battery if it is significantly undercharged.

6. Inspection of tires

7. Inspection of belts

8. Inspection of air filter

9. Inspection of spark plugs

The regular spark plug's insulating ceramic is intact, with no signs of cracking or leakage. The spark plug clearance is {{0}}.8 +/- 0.0mm, and during discharge, the spark appears blue. If any anomalies are detected, adjustments to the clearance or replacement of the spark plug may be necessary.
