Ten Common Troubles of Trucks

Trucks runs on the road every day, there will inevitably be some small faults. If the driver finds them out in time, it can avoid further losses. Next we will summarize some simple truck maintenance and testing methods. They are suitable for light truck, medium truck and heavy truck.

1. Engine Oil Quantity Inspection

Park the truck on a level surface. Pull out the vernier scale to check the oil quantity. If the oil is bright within the two lines (F) and (L), it is within the normal range. If it is lower than the (L) position, the oil should be added, and the liquid level after refueling should not be higher than (F).

2. Engine Coolant Inspection

Never open the radiator cover while the engine is in a hot state, otherwise you may be burnt by splashed coolant or high temperature steam. After the engine is cooled, check if the liquid level of the coolant is between the full and low level. Otherwise, distilled or purified water (no mineral water) or frozen liquid should be added. The liquid level after adding water should not exceed the full level. If the coolant is found to decrease rapidly in a short period of time, check if the cooling system leaks or check it at the service station.

3. Brake Liquid Inspection

Braking is normal when it is between high and low level. If the brake liquid is close to the lower limit or lower than the lower limit, it indicates that there may be leakage in the system or the brake pad is excessively worn. It should be repaired at the service station in time. When adding brake liquid, pay attention to adding the same type of brake liquid to prevent damage to the leather cup, and pay attention to protecting the paint to avoid corrosion of the paint surface.

4. Clutch Master Pump Liquid Inspection

If the clutch liquid level is between high and low liquid level, it means normal. If it is lower than the standard line, the master pump or the pump bowl may be damaged. In the engine running state, there will be a phenomenon that the gear is difficult or impossible to be geared. Please go to the nearest service station for repair.

5. Battery Maintenance Inspection

Check whether the battery is firmly fixed. The electrolyte should be between the upper and lower limits. When the line is close to the lower limit, add electrolyte or distilled water to the high limit. Keep the battery positive and negative cable in good contact and keep the battery clean and dry. If the vehicle is placed for a long time, remove the positive and negative cables of the battery, and re-wire the engine for about 20 minutes after about half a month. If the power is obviously insufficient, it should be charged in time.

6. Belt Inspection

When starting the engine or driving the vehicle normally, if the belt sounds, one case is that the belt has not been checked and adjusted for a long time, and it can be adjusted according to normal standards. In another case, the belt is aging and needs to be replaced.

7. Air Filter Inspection

If the air filter is too dirty, it may cause the engine to work poorly, the fuel consumption becomes large, and the engine may be damaged. When checking the air filter, if the dust is found to be less and the blockage is lighter, it can be cleaned with high-pressure air blown from the inside to the outside. The too dirty air filter should be replaced in time.

8. Tire Inspection

The tire pressure should be checked at normal temperature every month. If it is lower than the normal standard, the tire pressure should be replenished in time. The air pressure should not be too high or too low, otherwise it will affect the safety of driving. Check the cracking of the tires and replace the tires in time when there is a safety hazard. 

9. Fuel Filter Inspection

If it is found that the oil supply is not smooth, check whether the fuel filter is clogged. If there are foreign matters, it should be replaced in time.

10. Spark Plug Inspection

The normal spark plug insulation ceramic is intact. There is no leakage phenomenon. When the spark plug gap is 0.8+-0.0mm, the spark is blue and strong. If there is an abnormality, adjust the gap or replace the spark plug.
