Receiver Driers and the 2016 Subaru Forester: What You Need to Know

For owners of the 2016 Subaru Forester, understanding the air conditioning system and its components can be pretty handy, especially when it comes to maintenance and repairs. One question that often comes up is whether this vehicle uses a receiver drier. After referencing technical sources and Subaru's official service documentation, it's clear that the 2016 Forester does not actually use a receiver drier as part of its air conditioning system. Instead, it utilises a different approach common in many modern vehicles called a receiver drier and accumulator hybrid system, or sometimes an accumulator is used rather than a receiver drier.

The main reason why the 2016 Subaru Forester does not have a traditional receiver drier is that it employs a variable displacement compressor along with an orifice tube system which relies on an accumulator rather than a receiver drier. This design choice is based on the fact that receiver driers are typically paired with expansion valves in liquid line systems, whereas orifice tube systems need an accumulator, which performs a slightly different role but shares some similar functions.

So why does this distinction matter? It comes down to the way the refrigerant moves through the air conditioning system. In systems with a receiver drier, the receiver drier is mounted on the high-pressure side between the condenser and the expansion valve. It is used to filter out moisture and debris, store refrigerant, and ensure only liquid refrigerant progresses past the condenser towards the evaporator.

Alternatively, systems that use an orifice tube have an accumulator located on the low-pressure side after the evaporator. This component catches excess liquid refrigerant to also prevent compressor damage and contains a desiccant to absorb moisture, much like a receiver drier does. Since the 2016 Forester's air conditioning system uses an orifice tube system, the need for a receiver drier is effectively replaced by the accumulator, making a separate receiver drier redundant.

While the 2016 Subaru Forester does not have a receiver drier, it is still important to understand the role a receiver drier serves in other vehicles and what its equivalent functions mean for Forester owners maintaining their air conditioning system.

A receiver drier acts as a crucial guardian within the A/C system. Its job is to make sure that moisture and debris are not circulating inside the system where they can cause corrosion, freeze-ups, or blockages. It also stores refrigerant to ensure a consistent flow through the expansion valve, which helps maintain efficient cooling. The receiver drier contains a desiccant, similar to silica gel, that soaks up any moisture, stopping it from turning into ice which can block refrigerant flow or corrode metal parts.

When servicing the A/C system of vehicles that do have receiver driers, such as older Subaru models or other makes with an expansion valve system, it is important to replace the receiver drier whenever the system is opened for repairs or component replacement. Why? Because once exposed to the atmosphere, the desiccant inside the drier loses its ability to absorb moisture and may already be saturated with water trapped during leaks or system failure. Failing to replace the receiver drier can cause poor A/C performance or potential damage to the compressor, leading to costly repairs down the track.

In addition to replacing the receiver drier during repairs, it is a good idea to keep an eye on A/C system performance and have regular servicing checks. Moisture and contaminants can sneak into the system through leaks, so proper maintenance doesn't just protect the receiver drier but also extends the overall life of the air conditioning unit.

For 2016 Subaru Forester owners, the equivalent to receiver drier care lies with the accumulator and general system maintenance. The accumulator absorbs moisture and contaminants like a receiver drier but is located elsewhere in the system. If an A/C repair or recharge is necessary, it is best to follow Subaru's servicing guidelines which often recommend checking or replacing the accumulator and inspecting any seals or lines for leaks.

Simple steps like keeping the A/C system free from leaks, ensuring the refrigerant charge is correct, and using quality replacement parts will help preserve the performance and reliability of your Forester's climate control system.

In short, while the 2016 Subaru Forester does not use a receiver drier, understanding its function in general A/C systems helps owners appreciate the importance of moisture control and system cleanliness no matter what their vehicle is fitted with. Regular check-ups and following manufacturer advice will keep the air conditioning blowing cold and comfortable through those hot Australia summers, without unwelcome surprises along the way.
