How to remove a refrigerator in a DAF 105: step-by-step instructions

Operation of the DAF XF 105 truck often requires autonomous living in the cabin, where refrigerator becomes an integral element of comfort. Over time, drivers are faced with the need to replace a failed unit or deep clean it, which is impossible without complete dismantling. This process requires care, since the design of the cabin provides for a dense arrangement of components.

Incorrect performance of the work can lead to damage to the plastic panels or a leak in the cooling system. In this article, we will analyze all the stages of removing the refrigeration module, paying special attention to the nuances of fastening and electrical connections. DAF 105 has its own characteristics that distinguish it from the newer models of the XF series.

Before starting work, it is necessary to prepare the tool and provide access to the niche. Typically, dust and small debris accumulate in this area, so it is recommended to take care of the cleanliness of the workspace in advance. DAF 105 models often use a specific type of latches that are prone to brittleness at low temperaturesso you should work in a warm room or heated cabin.

Tool preparation and workplace

For high-quality dismantling, you will need a standard set of plumbing tools. A Phillips screwdriver with a magnetic tip will do the main job, since screws are often located in hard-to-reach places. You will also need a set of heads, including sizes 8 and 10 mm, which are most common in fastening interior elements DAF.

Be sure to turn off the power to the on-board network before starting any manipulations with the electrical wiring. This is critical to prevent short circuits that could damage the control unit or fuses. Remove the terminals from the batteries or use a special disconnect switch if it is installed on your tractor.

Organize good lighting in the sleeping area. The shadow from the body may interfere with the view of small fastener parts. It is most convenient to use a headlamp or a portable LED lamp on a flexible leg to see the condition of the plastic around the niche.

• 🔧 Phillips and slotted screwdrivers of different sizes
• 🔩 Set of sockets and sockets (ratchet)
• 🔦 Powerful light source (flashlight)
• 🧤 Gloves to protect hands from sharp edges

Check the availability of rags or paper towels. When removing the refrigerator, it may be necessary to wipe the surfaces from condensation or technical grease. Clean hands and tools are the key to ensuring that you do not stain the light-colored upholstery.

Access to the niche and removal of decorative panels

The refrigeration unit in the DAF 105 is usually hidden behind decorative panels under the berth or in the rear wall of the cab. The first step is to carefully remove the visible screws holding the faceplate in place. They are often closed with plastic plugs that need to be pryed off with a thin knife or awl.

After unscrewing the fasteners, do not jerk the panel sharply. Plastic becomes brittle over years of use, and a sudden movement can break the hidden latch tabs. Smoothly move the element to the side, controlling the force at each fastening point.

⚠️ Attention: When removing panels, pay attention to the wiring harnesses that may pass behind them. Do not damage the insulation with the edges of the metal body elements.

If the panel does not give way, check whether there are hidden screws in the depths of the holes. In some trim levels DAF XF 105 there may be additional latches on the side of the driver or passenger seat. Inspect the perimeter of the niche carefully.

It is better to immediately remove the removed panel to a safe place so as not to accidentally step on it or drop heavy parts. Organize the space so that nothing interferes with further work with the main unit.

Disconnecting the electrical wiring

The next stage is turning off the power. The electrical circuit of the refrigerator in the DAF 105 is quite simple, but requires careful attention to the contacts. Find the connection connector, which is usually located at the bottom of the niche or on the side of the compressor.

Press the pad lock and smoothly pull out the plug. If the joint is soured or very tight, do not use excessive force. You can gently rock the connector from side to side or use a special lubricant for the contacts, if access allows.

Check the condition of the wires for chafing or melted insulation. This is a common problem in high mileage trucks where vibration causes damage to harnesses. If defects are detected, they must be eliminated before installing new equipment.

Sequence of actions:
1. De-energize the board (ground switch).
2. Find the refrigerator power connector.
3. Press the latch and disconnect the block.
4. Visually inspect the wires.

Make sure that the wires are not stretched and do not interfere with the removal of the refrigerator body itself. If necessary, you can temporarily fix the harnesses with masking tape to the elements of the cabin frame.

• 🔌 Inspect the contacts for oxidation
• 🧵 Check the integrity of the wire insulation
• 🛡️ Make sure the harness is securely fixed

Removing the housing fastening elements

The main weight of the unit is held by metal brackets or plastic guides. In the DAF 105, the most common type of fastening is a combination: bolts at the bottom and latches at the top. Start with the bottom row of fasteners, as they take the main load.

Use a wrench with an extension if access to the bolts is limited. Move the tool carefully to avoid touching or damaging adjacent systems such as heater ducts or bed wiring. The fastener metal may be coated with anti-corrosive, which makes unscrewing difficult.

⚠️ Attention: Do not unscrew all the bolts at the same time. Loosen them gradually, moving from one to another, to avoid distortion of the structure and jamming of the threads.

If the bolts are stuck, use a penetrating lubricant (WD-40 or analogues) and give it time to work. Threaded connections in the cab floor area are often exposed to moisture and reagents from the road.

After removing the main fasteners, check for additional fixation points. Sometimes the unit may be glued to a vibration-isolating tape, which will have to be carefully trimmed with a knife.

Removing the refrigeration module

The most crucial moment is the physical removal of the housing. The refrigerator in the DAF 105 weighs a lot, and due to its dimensions it is inconvenient to hold with one hand. It is best to perform this operation with an assistant to control the position of the unit.

Grip the device by the metal frame, avoiding grabbing plastic elements or heat exchanger tubes. Plastic can crack under load, and thin tubes can easily be deformed, leading to freon leakage.

Pull the module out using a progressive motion, gently rocking it from side to side if it gets stuck. Make sure nothing is catching on the corners of the niche. When removing, residual condensation may spill out, so be prepared to use a rag.

After removal, inspect the niche for dirt, rodents, or forgotten items. Drivers often lose small tools or personal items behind refrigerators that should be returned to the owner.

• 🤝 Get an assistant to support the weight
• 👐 Grab only the metal frame
• 🚫 Avoid putting pressure on plastic parts
• 🧹 Clean the vacated niche

If you are planning to install a new device, compare the seats of the old and new unit. It may be necessary to relocate the mounting holes or adapt the electrical connector.

Specifications and compatibility

When replacing equipment, it is important to consider compatibility parameters. Not all refrigerator models are suitable for installation in the DAF 105 niche without modifications. Below is a table with approximate parameters of standard and alternative solutions.

Pay attention to the current consumption. More powerful models may require replacing fuses or installing an additional relay. The standard DAF 105 wiring is designed to carry a certain current, and exceeding it is dangerous.

Also consider the noise level when choosing a replacement. In a small truck cab, this becomes a critical factor for a comfortable ride. Quiet compressors are usually more expensive, but the difference in price is compensated by the quality of sleep.

Is it possible to install a refrigerator of higher power?

Theoretically, it is possible, but this will require replacing the wiring and installing a separate fuse. The standard electrical network may not be able to withstand the starting currents of a powerful compressor, which will lead to a fire.

Cleaning and servicing the niche before installation

Before installing a new or serviced refrigerator, you must carefully prepare the seat. years of operation accumulate dust, grease, and sometimes mold in hard-to-reach corners. Use a vacuum cleaner to remove loose debris.

Wipe the surfaces with a damp cloth and neutral detergent. Do not use aggressive chemicals that can damage the plastic elements of the interior or cause corrosion of the metal parts of the frame.

Check the condition of the thermal insulation material, if it is present in the niche. If the insulation has become unusable, it is better to replace it so that the refrigerator operates more efficiently and consumes less energy.

⚠️ Attention: Make sure the niche is completely dry before installing electrical equipment. Residual moisture may cause contact corrosion or short circuits.

Also check the ventilation holes. In the DAF 105 they often become clogged with fluff or dirt, which impairs heat transfer. Blow them with compressed air or clean them with a brush.

Frequent errors during dismantling

Many drivers make typical mistakes, trying to save time or acting without instructions. One of the most common is ignoring the need to de-energize the network. This can lead to electronics burning out if the tool is accidentally shorted to the terminals.

Another mistake is using brute force when removing panels. The plastic in older trucks is very brittle and a broken latch can be difficult to repair. Always look for hidden fasteners before pulling a part.

Forgotten tools inside a niche are another common occurrence. Vibration during movement may cause the screwdriver or bolt to become caught in moving parts or cause a short circuit. Always conduct an inspection before final assembly.

The wrong sequence of actions can also complicate the process. For example, trying to remove a refrigerator without disconnecting the wiring will cause tension on the wires and damage them. Follow the logic: preparation -> access -> shutdown -> dismantling.

Questions and answers (FAQ)

Do you need to drain the freon before removing the refrigerator?

If you remove the entire refrigerator for replacement or repair outside the cabin, draining the freon yourself is not necessary and is dangerous for ecology. This is done by a service specialist. If you are only changing the compressor or pipes, then bleeding the refrigerant is necessary.

Is it possible to remove the refrigerator alone?

Theoretically, it is possible if you have experience and strength, but the design of the DAF 105 requires working in tight spaces. The unit is heavy and uncomfortable. The risk of dropping it on the floor or damaging the cab panel is very high, so the help of a partner is recommended.

Where can I find the electrical connection diagram?

The diagram is usually located in the car's owner's manual (Electrical Diagrams section) or on a sticker inside the niche/under the hood. You can also use the official DAF service manuals for the XF 105 model.

What to do if the mounting bolts are rusty?

Spread the connections generously with penetrating lubricant and leave for 15-20 minutes. You can use heat (be careful not to melt the plastic), but it is better to use mechanical action - a light tap with a hammer through the extension to destroy rust in the thread.
