Faced with car-love problems, did you choose to line up to the repair plant or did you want to do it yourself and be discouraged by the cold toolbox? The mastery of the basic tools is an essential road to the progress of each car's owner。
Basic wrench
The wrench is like an extension of a mechanic in a world of steam repair. White's first contact is usually with the opening wrench and the clubs wrench. The opening wrench, although convenient to pick up, because it has only two stress points, is very prone to “sliding” in the face of a badly rusted bolt, leading to a spiralling。
In contrast, the plum wrench is able to surround the bolts in all directions, with a more even-handed response, and is the preferred option to remove the tights. The senior technician suggested that, space permitting, priority should be given to the use of plum ends to untangle. If you are a beginner, it is suggested that a combination of wrenchs and a single opening of clubs should be purchased to balance efficiency and safety of construction。
The vehicle parts are now extremely sophisticated and, when using the wrench, it is important to ensure that the wrench specifications fully match the bolts. Do not try to screw the british bolt with a male wrench, even if it looks “similar” and a tiny gap may destroy the parts in an instant, and it is strictly forbidden to use a long pole to add to the force, not only to damage the tools, but also to break the bolt。
Cluster of cylinders of thorns
If the wrench is a rifle, the drum and the thorn wheel wrench are machine guns, which are highly efficient. The core of the wrench lies in the one-way gear structure inside it, so that you don't have to take it off repeatedly, put it on a tool, and just a small swing to do the twist. It's like a life-saving straw in a narrow space like the engine room。
The tubes are divided into three common specifications of 1/4, 3/8 and 1/2, which represent the size of the driver's head. White's introduction recommends a set of 3/8-series first, with moderate force to cover most routine vehicle maintenance. Bearing in mind that the wrench is used only for rapid spin-off or pre-heavy, it is absolutely impossible to use the wrench for violent disassembly, and that the initial relaxation should be handed over to the long handle or breaker。
In addition, the poles and the lunars are the best partners in the kit. When you meet a screw hidden beneath the vents, the wiring of power can change. However, attention is drawn to the fact that power output can be depleted and easily evaporated by the use of the all-way period, which requires that the end of the tube be stabilized with another hand to prevent damage to the head of the screw。
Screwdrivers and pliers
Looks like a simple screwdriver, actually. In car repairs, we use crosses and one-word screwdrivers most often, but be careful with "symmetry." if the screwdriver's head is smaller than the slot, force can cause teeth to slip. Senior technicians usually have a set of shock screws designed to deal with screws that are stuck to death by heat or corrosion。
The pliers play the role of "taker" in the car repairs. Pointy pliers are suitable for cutting off small parts deep in the cracks or lifting fuses; pumps are very easy to remove when they open. There is also an indispensable tool: a strong clamp, which provides a very strong lock, the last line of defence for dealing with deformed bolts。
In the use of clamp tools, avoid holding surfaces of sophisticated parts. Carpentry teeth can damage the coating or even the structure of the parts, and if the coatings are processed with fine coating, it is recommended that a protective tape be placed at the plier. Details determine success and failure, and a professional car mechanic will never leave unnecessary scratches after construction。
Twisting precision control
A lot of whites think the screws are as tight as possible, which is actually a huge mistake. Each bolt has a standard twist that is designed to be too tight to cause the bolt stretching to deform and even to break, while the pine triggers oil spills or spreads. The wrench was created to address this problem, and it is a watershed that distinguishes between “amateur” and “professional”。
When using a wrench wrench, the maintenance manual should first be consulted to determine the target values. When the scale is adjusted, it works smoothly until it hears the sound of a “single” or feels a clear disconnect. There is no way to make up for that. Overstretching would invalidate the preset of the wrench and even damage its internal spring structure。
In particular, when replacing spark plugs and tight rim bolts, the wrench must be used. If the wheel bolts are not fixed to the angles by standard twists, they may cause brakes to deform and generate high-speed shaking. When the wrench is used, remember to adjust the tic to the minimum to release the internal spring pressure to ensure accuracy at the next measurement。
Safety upgrade
Capital repairs are a risky activity, and safety always comes first. It is an extremely dangerous practice for many whites to drill directly into the vehicle with their jacks. The stability of car jacks, which are used only for emergency replacements, is not sufficient to sustain long maintenance operations, and can never operate under a single jack。
The correct approach is that when a vehicle is lifted using a hydraulic jack, it must be placed on a safety stool (stool) at the substrate of the vehicle. When the racks are securely placed, the jacks fall slowly so that they are fully heavy. Prior to the official operation, the vehicle was rocked hard to confirm that it was as stable as tarzan before entering the vehicle. This “dual insurance” protects your life to the greatest extent possible。
Moreover, protective equipment cannot be ignored. Tinle gloves can isolate the chemical substances from the oils and protect the skin; eyeglasses can prevent the loss of rust and oil stains to the eye when the parts of the chassis are removed. Today, in 2026, health maintenance has become an industry consensus, and it is not an expression of professionalism that the wearing of protective gear should be seen as a moral imperative。
Tool maintenance techniques
Good tools need to be “fed”. At the end of each maintenance, the oily tools are not thrown directly into the box. The oils and brake oils are of a certain corrosive nature and long-term residues can damage the electroplating layer on the surface of the instrument and lead to rust. A habit of wiping every tool with clean cotton cloth, the cleaning of which directly affects its lifespan。
Precision measurement tools, such as jigsaw and wrench wrench, should be stored in specially designed tideproof boxes. If the instrument is found to be cracking, deforming or thorn-wheeling agency cardon, it should be replaced in a timely manner and should not be tempted to continue using it. The damaged tools may break at any time when they are active, damage the operator or damage expensive car parts。
Finally, it is recommended that an orderly tool management system be established. Whether it is walled or multi-layered mobile cabinets, it is required to “back to the ground”. In the maintenance process, the most waste of time was often not the construction itself, but the search for the missing kit 10. A clean operating environment that makes your diy process more fun and efficient。
It's not just a technology, it's a fear and love for machinery. From the knowledge of the wrench to the skilled use of the wrench, each step of accumulation lays the foundation for a safe vehicle. It is hoped that this guide will help you to open the door to diy and enjoy the success of repairing the car. Which one do you want the most? Or have you encountered any embarrassment in the use of tools? Welcome to the comment section. Let's talk about progress
