DIY van repair

In detail: do-it-yourself van repair from a real master for the site my.housecope.com.

Transportation of goods is often carried out using special vehicles. Some of the most popular are vans, which can have completely different configurations.

Very often, during the operation of a structure, its main parts are damaged. In this case, it is advisable to repair vans immediately, as this will optimize the further process of transportation.

A van can be called cars that have a closed body type. The main material for the manufacture of such structures can be:

  • metal;
  • special panels that combine several substances.

Vivid representatives of these structures are trucks that transport food products from warehouses to certain stores. Very often they can be supplemented with special cooling systems.

Vans can have a variety of designs from light vehicles to heavy trucks carrying bulky goods.

Damage to the body of such vehicles can be completely different. Before starting repair work, you should understand the cause of the breakdown.

The remediation process can be divided into several stages:

  1. Installation of protection systems, both on the sides and behind.
  2. Installation or replacement of special fasteners for the product. There are several options for such devices, but they should be repaired very carefully so that in the future there is no need for control during transportation.
  3. If the doorways are damaged, they are completely replaced. Sometimes this can be corrected by installing some individual elements.
  4. Installation of new panels in place of the damaged ones. In this case, it is imperative to check the condition of the frame for all kinds of cracks, bends, etc. If necessary, the entire structure is strengthened by welding and attaching additional elements, such as metal corners, etc.

Very often there is a need to maintain a certain temperature inside the structure. To do this, during repair work, you can additionally seal the walls with special materials.

This type of work is rather complicated and cannot be performed at home without the presence of special equipment. The best solution is to entrust the repair of the van to specialists who have certain skills.

We watch the repair of a car van in the video:

Today, refrigeration equipment on the Gazelle is installed by many owners of these wonderful commercial vehicles. Often, this is due to the desire not only to improve the functionality of the body, but also to significantly increase your income from cargo transportation.

If you have a flatbed car, then, first of all, you should attend to the thermal booth. You can buy ready-made (including used ones), or you can weld the frame yourself. You will need a profile pipe 50x50x2 mm (12 meters) and 50x25x2 mm (24 meters). Optimal dimensions for installation on board: 3.2 x 2.0 x 2.0 meters. The money for the material is about 4,000 rubles. Here's what we end up with:

Next, we collect the insulating "sandwich":

  • sheathed outside with suitable sheet material (for example, polymer coated metal)
  • inside we lay 5 cm of insulation (foam is suitable, since it is inexpensive, and is sold in the required thickness)
  • the surface inside the booth is also sheathed with something that is not subject to corrosion (galvanized or sheet plastic is suitable)

Galvanizing will cost you about 200-250 rubles per square meter, plastic - 300 rubles.per square meter, foam - 180 rubles per square meter Corrugated aluminum can be used on the floor, although this is not the most budget option (about 1800 rubles per square meter of sheet 2 mm thick).

You will have to tinker with the gate in order to weld them smoothly and efficiently (without distortion of the hinges). Operation of a refrigerated Gazelle with "curved" body doors is one torment. Since the dimensions of the structure are quite impressive, it is not easy to bring them to zero in garage conditions. Pay special attention to this, sometimes it takes a whole day to weld and fit the gate.

If you decide to install refrigeration equipment in a Gazelle van, then as thermal insulation, you can consider spraying polyurethane foam directly on the inner surface of the van:

A 3 cm thick layer will completely replace 5 cm of polystyrene, PPU is the highest quality insulation.
In the future, cover it with sheets according to the scheme suggested above.

In conclusion of the first point, take a look at a ready-made thermal box for a gazelle, which you can make yourself:

What you will have to deal with:

  • compressor
  • electronic control unit (refrigeration automation)
  • condenser unit (outdoors)
  • evaporator unit (in a thermal box)
  • pipes and hoses with refrigerant (freon)
  • wiring

The compressor ensures the pumping of freon throughout the entire refrigeration circuit. It is installed in the engine compartment and is driven by a belt of ancillary units. Brackets and a new (longer) strap may be included with the refrigeration kit you purchased. If not, you will have to make metal staples with your own hands and pick up a longer drive belt in an auto parts store.

It is worth noting that the refrigerator compressor can also operate on a voltage of 220 V. For this, a special cord is usually provided. The mode of operation "from the socket" is used in those moments when the car is at loading / unloading, the Gazelle engine at these moments can be turned off.

The electronic control unit is installed in the driver's cab. It serves for setting and displaying the temperature in the refrigerator box, and also monitors the state of the entire system. When necessary, it turns on the fans on the evaporation and condensation units, controls the operation of the compressor, reports errors.
Wired to compressor, evaporator and condenser.

The condenser is an outdoor unit located on the street, designed to remove heat from the thermal box. Equipped with a fan to increase the amount of outside air passing through it (to remove more heat per unit of time). Usually installed on the front of the cargo area or on the roof. This improves airflow when the vehicle is in motion.

The evaporator is a heat exchanger block, which is located in the cooled volume (in the body of the Gazelle). The air in the thermobox circulates through the evaporator (using the built-in fan) and is cooled. The evaporator unit is also located on the front interior of the body or on the roof. This allows for more convenient loading of the product.

Please note that there are two pipes (or hoses) leaving the refrigerator compressor, one for "discharge", the other for "suction".

The units are connected according to the following scheme:

  • from the discharge port of the compressor, the tube goes into the inlet of the condenser
  • from the outlet of the condenser, the tube goes to the inlet of the evaporator
  • from the outlet of the evaporator, the tube goes to the suction of the compressor, thereby closing the system

The sequence should be described in the installation manual for the refrigeration system you purchased.

It should be said that monoblocks are often found (combined unit of condenser and evaporator). Such a block is simply inserted into a slot in the truck bed. In this case, only the compressor discharge port with the condenser intake pipe and the evaporator outlet pipe with the compressor suction port need to be connected, thereby greatly simplifying the installation of refrigeration equipment.

If you managed to assemble the equipment with your own hands, you have a direct road to where the car air conditioners are refueled. Filling of freon into the refrigeration circuit should be carried out only by an experienced mechanic; without special tools and knowledge, you will not be able to bring the refrigerator into operation.
You can also go to a company that installs refrigerators professionally, but usually their services are more expensive than those who fill air conditioners.
Filling a refrigerator with freon costs from 2000 rubles.

If you are not ready for self-assembly of the refrigerator unit with your own hands, then it is better to entrust it to professionals.

For example, consider the two most popular sets of refrigeration equipment.

(price with assembly 3300 Euro)
The delivery set includes units for evaporation, condensation, compressor and electronic unit. Also included is a compressor for operation from a 220V network. The hydraulic circuit units are connected with flexible hoses.

The units are designed for cooling volumes from 13 to 24 cubic meters. depending on the temperature (from 0 to -20 degrees). All units are made of high-quality steel with a powder coating, the condenser body is made of ABS plastic. The equipment of the Italian company Zanotti is widespread and enjoys well-deserved respect. The only thing that confuses today is the Euro rate. On a well-known classifieds website, we managed to find used kits at prices starting at 60,000 rubles.

(Price with assembly 2400 Euro)
Russian manufacturer of refrigerated trucks.
The principle of operation is the same as that of Zanotti. A significant difference is that it does not work from a 220V network with a standard delivery set.

The cooled volume is from 11 to 16 cubic meters. (a lower value is at minus 20 degrees, a larger value is at 0 degrees). All units are imported, in fact, only Russian housings and assembly. Quite a decent option on a limited budget. We found a used ear kit from 30,000 rubles.

If you decide to order a turnkey installation of refrigeration equipment on a Gazelle, the most correct solution would be to contact an official dealer of the brand of refrigerators you have chosen. This will save you from problems with spare parts and warranty service of equipment, and also implies professional installation of all units.

If you like the installation of equipment with your own hands, approach the issue with all seriousness, try to get the advice of an experienced specialist, or at least study the basic principles of refrigeration technology.
