A failed starter in the middle of the track or a burst cooling system hose can turn a pleasant journey into a long wait for a tow truck if there is no basic equipment in the trunk. motorist. It is the availability of specialized tools and supplies that often determines whether you can fix the malfunction on your own in fifteen minutes or spend a day on the sidelines. It is critically important not just to buy a ready-made case in a supermarket, but to form an individual kit that takes into account the real operating conditions of your vehicle, the climatic zone and the technical condition of the car.
Competent equipment of the trunk requires a systematic approach, where each item has its own purpose and is in quick access. Unlike the garage armoury, kit It should be compact, protected from moisture and vibration, but functionally complete. Many drivers make the mistake of relying on the minimum kit supplied by the manufacturer, which is often limited to just a jack and balloon key, ignoring the need for first aid, diagnostics and emergency repairs.
In this article, we will discuss in detail what should be included in the ideal set, how to organize the space in the trunk correctly, and why some popular “universal” sets may prove useless in a critical situation. You will learn about the technical nuances of choosing tools that actually work rather than take up space, as well as the legal requirements for equipping a car.
Basic equipment: tools for emergency repairs
The foundation of any road arsenal is a set of hand tools that allows you to perform the initial dismantling of the nodes, tighten the mounts or replace the failed element. First of all, attention should be paid to the quality of the metal: cheap alloys from which budget sets are made, often “lick” after the first use or break when applying a regulatory effort. Chromovanadium steel (Cr-V) is a standard that provides the required hardness and viscosity of the material.
The composition of the basic set should include not only screwdrivers and keys, but also specialized devices to work with specific nodes of your car. For example, to remove the battery terminals often requires a special key, and to access some filters - elongated heads. Universality plays a cruel joke here: too large a set of cumbersome, and too small is useless. The optimal solution is a medium-sized case with a rattle and a set of heads from 8 to 24 mm.
- 🔧 A set of heads with a rattle and an extension cord (the basis for unscrewing the wheel nuts and protecting the crankcase).
- 🔧 Combined carob-on-leaf keys (basic dimensions: 10, 12, 13, 14, 17, 19 mm).
- 🔧 Screwdrivers with magnetic tips (cross and slitting of different sizes).
- 🔧 Passengers, bogocreuses and pliers (for working with wiring and clamps).
- 🔧 Dilution key (for non-standard nuts and fittings).
⚠️ Caution: Cheap tools made of silumin or soft steel can break right in the hands, causing injury. Check the Cr-V or Cr-Mo markings on the instruments before buying.
It is also important to consider the ergonomics of the tools. In the conditions of limited space under the hood or on the side of the road in the dark to use uncomfortable or slippery keys is extremely difficult. The handles should have an anti-slip coating, and the edges of the tools should clearly meet the standards so as not to tear the thread on the bolts.
Engine and electrician start systems
The most common problem faced by drivers, especially in the cold season, is a discharged battery. In this case, the only salvation is the trigger wires, which should be in the trunk of each car. The quality of the wires is determined not only by the length, but also by the cross-section of the copper veins: to start a gasoline engine with a volume of up to 2.0 liters, 16 mm2 is enough, while for diesel engines or engines with a volume of more than 3.0 liters, a section of at least 25-35 mm2 will be required.
In addition, in a modern car, electrical faults can be caused by fuses burning out or relay failure. The presence of a set of spare fuses of various denominations allows you to quickly restore the operability of important systems, such as lighting or fuel pump. To diagnose the state of the battery and on-board network, an indispensable device is a multimeter or at least a simple voltmeter, which allows measuring the voltage at the terminals.
How to properly light up the car
First, connect the donor's plus terminal with the plus of the discharged battery. Then connect the donor's minus to the donor's minus. The last wire (minus) connect not to the minus of the discharged battery, but to the "mass" (unpainted metal part of the engine or body) of the receiving car to avoid sparking near gasoline vapors.
The issue of lighting deserves special attention. Working in the dark without an additional light source is almost impossible. A powerful LED light with zoom function and magnetic base will allow you to fix it on the body and work freely with both hands, checking the knots under the hood or changing the wheel.
Space organization and storage
Chaoticly abandoned tools in the trunk turn into projectiles under sharp braking and occupy usable space. Proper organization involves the use of rigid cases, organizers or special bags with locks. It is important that the set was fixed: in case of an accident, an unsecured box with tools can cause serious injuries to passengers.
For storage, it is recommended to use modular systems that allow you to group items according to their purpose: “electrics”, “wheel repair”, “consumers”. This speeds up the search for the right item in a stressful situation. It is also worth providing protection from moisture, since tools stored in the trunk are subject to condensation and temperature changes, which leads to corrosion.
- 📦 Hard plastic case with cells (protects against dust and shocks).
- 📦 Bag-organizer with Velcro (compact, but less protects from moisture).
- 📦 Mesh pockets on the backs of the seats (for frequently used trifles).
- 📦 Fixing belts or Velcros for fixing the case in the niche of the trunk.
The optimal solution is to divide the set into two parts: “operational” (located in an easily accessible place, contains a cable, a first aid kit, a fire extinguisher, a flashlight) and “main” (tools for serious repairs, stored in the back of the trunk). This allows you not to go through the entire trunk in search of a cable if you need a quick evacuation.
Seasonal features: winter and summer sets
Operating the car in different climatic conditions dictates its requirements for the contents of the trunk. In winter, the list of necessary items is expanded due to items that help to survive frosts and snow drifts. In the summer, the means for cooling and repairing punctured tires in the conditions of red-hot asphalt come to the fore.
In winter, anti-icing fluids and scrapers are critical, but more serious means such as a snow shovel and a high-strength towing cable are also needed. Frozen locks, frozen doors and snowdrifts under the wheels are typical winter problems, the solution of which should lie in the trunk. In summer, gloves are relevant for working with hot parts and water supply not only for drinking, but also for adding to the radiator.
The temperature of the storage also affects the choice of materials. Plastic in severe frost becomes fragile, and rubber products (shoes, tourniquets) can crack. Therefore, all elements of the kit must have the appropriate operating temperature range specified by the manufacturer.
Table: Comparison of finished sets and self-assembly
Many motorists face a choice: buy a ready-made set in the store or assemble it yourself. Each approach has its advantages and disadvantages, which are worth weighing before buying. Ready-made kits often look presentable but may contain a poor-quality tool, whereas self-assembly allows you to control the quality of each item, but it takes time and knowledge.
| Criteria | Ready-made set (store) | Self-assembly |
|---|---|---|
| Price. | Usually lower due to mass production | Higher, as each instrument is purchased separately |
| Quality of instrument | Often medium or low (especially in low-cost segments) | You can choose professional brands (Force, Ombra, Jonnesway) |
| Complementation | Fixed, may contain excess or lack the necessary | It is fully adapted to your car and needs. |
| Packaging | Beautiful case, convenient for storage | You need to select a case or bag separately. |
If you don’t have a deep technical knowledge, a ready-made set from a well-known brand can be a good start, which can be supplemented later. However, for experienced drivers who know the weaknesses of their car, self-assembly is the only right solution to ensure that the tools that you may need are available.
Legal requirements and security
There is a list of items, the presence of which in the car is regulated by traffic rules and technical regulations. The absence of these items can result in a fine, but more importantly, they ensure the safety of life and health. In Russia and many CIS countries, the first aid kit, fire extinguisher and emergency stop sign are mandatory.
The first aid kit should be equipped according to the current orders of the Ministry of Health, with an unexpired shelf life of drugs. The fire extinguisher must have an appropriate volume (usually 2 liters for passenger cars) and a valid check. The emergency stop sign must be made of retroreflective material and installed securely in the trunk to be accessible at any second.
⚠️ Attention: The use of an expired first aid kit or fire extinguisher with an expired inspection period is equivalent to their absence and is a traffic violation. Check the dates regularly!
In addition to the mandatory minimum, the legislation recommends, but does not require, a reflective vest. However, leaving the car on the roadway in the dark or in poor visibility, using the vest is a matter of survival. This item should also be stored in an easily accessible place, not in the back of the trunk.
Useful little things and consumables
Besides the large instrument, there is a category of small but extremely important items that are often forgotten. Insulation (especially reinforced), WD-40 or its analogues, a set of clamps for pipes, rags and gloves are those things that take up a minimum of space, but can save the situation. It is also worth having a small supply of technical fluids: motor oil, antifreeze and brake fluid.
For modern cars with a large number of electronics, it will be useful to have a power bank of large capacity for charging gadgets, as well as an OBDII diagnostic adapter, which through a smartphone can indicate a specific engine error. This helps to make an informed decision: whether it is possible to continue the movement or a tow truck call is required.
☑️ Checklist before the long road
Do not neglect personal hygiene and comfort items: wet wipes, paper towels, drinking water and a small supply of food. In a situation of prolonged repairs or waiting for help, these little things become critical to maintaining strength and calm.
On-site diagnostics and repairs
The ability to use the available kit for diagnosis and minor repairs is a skill that every driver should have. Knowing the main symptoms of malfunctions allows you to quickly localize the problem. For example, the whistle of belts can be temporarily eliminated by lifting or replacing them, and leakage of pipes by installing clamps.
For qualitative diagnostics in the field, it is useful to have an observation mirror on a telescopic pen at hand. It allows you to look into hard-to-reach places under the hood or under the bottom of the car without having to lie down on the asphalt. Also indispensable is the “third hand” – a device for fixing parts or wires during soldering or assembly.
The basic principle of assembling a set is that it is better to have 10 quality things that you know how to use than 100 useless ones that take up space.
Regular inspection and updating of the contents of the trunk is the key to success. Before each winter season and before long trips, take 10 minutes to check the charge of the lights, the expiration date of the harness and the availability of all the keys. Only in this case, your set of motorists will become a reliable assistant, and not just a load in the trunk.
Do I need to bring a hammer and a chisel?
Yes, these tools may be needed to knock out the soured fingers of the caliper, remove old rusty parts, or even break the glass in an emergency if the doors are jammed. It is best to have them in the trunk, even if they are rarely used.
Which fire extinguisher is better: powder or carbon dioxide?
Carbon dioxide (OC) is preferred for the car, since it does not soil the cabin and does not create smoke when used, and also does not spoil electronics. Powder (OP) is cheaper, but the powder is difficult to wash and it can cause contact corrosion.
How often should I check the expiration date of the medicine cabinet?
The shelf life of the first aid kit is usually 5 years, but individual drugs (bandages, tourniquets) may require replacement earlier. It is recommended to check the first-aid kit every six months, especially before the summer and winter season.
Can I store tools in the car interior?
It's not recommended. When a sharp braking or collision heavy metal objects turn into dangerous shells. In addition, tools can scratch the upholstery and interfere with the control of the car.
Why do you need reinforced tape?
Ordinary insulation (PVC) in the cold bluffs and peels off, and in the heat floats. Reinforced insulation (with a fabric base) keeps the temperature stronger to break and can temporarily seal the cracked pipe or fix the hose.
