What should be paid attention to before and after startup? Let's hear what the professionals say.
The ancients said: 'In a group of three, there must be a teacher for me.' The more people you interact with, the richer your experience becomes. Whether they are in the same line of work or a different industry, chatting more when you have the chance can help you absorb a lot of knowledge and wealth. Here, let's share with fellow car enthusiasts the experiences of a few different car repair masters.
A master specialized in engine repair will remind car enthusiasts what preventive measures should be taken before and after starting the vehicle.
The engine is equivalent to the heart of the human body. Once the engine has a problem, it can make the vehicle struggle even on flat roads, and in severe cases, it can be almost immobile. Listen to how professional engine mechanics remind truck drivers.
1. Before driving, you must check if there is any oil or water on the ground under the engine. If there is oil or water on the ground, there is definitely a leak in the engine, which must be repaired promptly.
2. Pull out the dipstick to check the engine oil level. This is something drivers must do every day.
3. Check whether the coolant level in the small water tank is normal. If the engine is severely low on water, the consequences can be serious, ranging from overheating to cylinder seizure. Additionally, repairing the car is troublesome, costly, and time-consuming.
4. Pay attention to any abnormal sounds from the engine while driving. If you hear unusual noises, stop immediately to check and find the cause of the fault.
5. When the engine red light on the dashboard comes on, it indicates a fault in some components, and you must stop and inspect.
▎Would a chassis repair technician give you these preventive methods?
1. Before departure, check if there is any oil leakage from the transmission and rear axle on the ground. If any oil leakage is found, it must be repaired.
2. Check whether the drive shaft bolts are loose. If the drive shaft bolts are loose, the vehicle will have vibration while running.
3. Push up firmly on the camshaft connection plate to see if the main bolts are loose. If the bolts are loose, the vehicle will shake while driving and there will be jolts when starting or braking.
4. If it is a multi-section drive shaft vehicle, check the bearings between the drive shafts for any fractures. If there is a fracture and it is not detected in time, the drive shaft may fall to the ground, which can have very serious consequences.
5. Check each wheel's spring leaf for broken pieces. Heavy-load vehicles need to be checked more frequently.
6. Check whether the wheel hub inner and outer ends have any oil leakage. Leak causes include: oil seal damage; hub cracks; bearing pitting; severe bearing sleeve wear, etc.
7. After fully inflating the tires and turning off the engine, listen for any air leaks in the vehicle's air pipes. Heavy-duty trucks use air brakes, and serious air pipe leaks can lead to brake failure.
▎What will the electrician tell you to pay attention to in daily life?
1. Always turn off the main power switch when parking and resting to prevent electric leakage.
2. If using a battery with battery fluid, regularly check the fluid level; insufficient fluid will shorten the battery's lifespan.
3. Regularly check that all vehicle lights are turned off to avoid unnecessary trouble.
4. Any unused wire ends must be properly wrapped, otherwise it can easily cause power outages or short circuits.
5. The generator and starter must be regularly maintained; only regular maintenance can help detect wear on the copper sleeves and carbon brushes.
▎The tire repair master will tell you how to choose and use tires normally:
1. Try to choose genuine tires with a warranty; tires without a warranty may be cheap but have no safety guarantee.
2. All tire pressures must be even.
3. Always check whether the tire bolts are loose; if not tightened in time, relatively tight bolts can easily break.
4. If you frequently enter and leave construction sites, you must constantly check whether stones are trapped in the gaps of the rear axle tires.
5. Tires must be replaced when they are severely worn, especially the guide wheel tires, which must be kept in good condition; otherwise, the consequences of a tire blowout are incalculable.
It is truly 'Listening to a gentleman's words is better than reading ten years of books.' After listening to the simple guidance and conversations of several car repair masters, I gained a lot of knowledge and understood much about vehicle maintenance. In fact, every industry has elite talents; as long as we listen more, observe more, learn more, and ask more in our daily life, we will accumulate more experience.
