Purpose and function in the air conditioning system

The air conditioning receiver drier in the Ford Focus Mk2 with a 2.0 TDCI diesel engine is responsible for separating moisture and impurities from the refrigerant. A properly selected component of this type:

• stabilizes pressure in the air conditioning circuit during compressor operation,
• reduces the risk of internal corrosion of lines and heat exchangers,
• protects the expansion valve and compressor from solid particles,
• supports the maintenance of consistent cooling performance under various engine load conditions.

For Diesel units, this is of particular importance, as the air conditioning system often operates under higher thermal loads in city traffic and when the vehicle is fully loaded.

Compatibility and technical parameters

The presented receiver drier is a component intended for use in the second-generation Ford Focus with a diesel engine. Using the vehicle manufacturer's original design allows for maintaining factory refrigerant flow parameters and appropriate accumulator capacity. The product has assigned part numbers and interchangeable numbers, which facilitates clear identification and selection of the correct component for a specific car configuration.

In practice, this means that with proper matching according to catalog data, compatibility with the factory layout of lines, mounts, and connections can be maintained without the need for system modifications. This is important both for standard service replacements and for repairs after collisions or interference with the air conditioning system.

Performance characteristics and advantages of use

Choosing an original Ford solution from the Receiver Drier Filters and Accumulators group allows you to maintain the consistency of the entire air conditioning system in terms of efficiency and durability. Key benefits include:

• maintaining factory operating parameters of the compressor and expansion valve,
• reducing the risk of air ingress and pressure fluctuations in the circuit,
• better repeatability of air conditioning performance in high ambient temperatures,
• easier service diagnostics thanks to compliance with manufacturer documentation.

For the user, this means more predictable air conditioning operation, uniform interior cooling, and less strain on other system components. In the case of diesel engines, this also translates into more stable operating conditions for the power unit during prolonged use of the air conditioning.

Condition, installation, and service application

The item is offered in used condition, which allows for economical repair of the air conditioning system while maintaining the manufacturer's original specifications. This type of part will prove particularly useful in situations where a quick replacement is necessary after mechanical damage or when upgrading an existing system without investing in a completely new installation.

Before installation, a standard service procedure is recommended: checking the system for leaks, replacing the refrigerant, and changing the compressor oil in accordance with the vehicle manufacturer's recommendations. Properly performed installation and system venting allow for fully utilizing the properties of the receiver drier and reducing the risk of recurring faults.
