Parts for your 2017 Suzuki Splash-Receiver driers

2017 Suzuki Splash receiver-drier: what it is and when to replace it

Based on the Suzuki Splash/Opel Agila B workshop literature for Heating & Air Conditioning (often labelled Section 7B in Suzuki service manuals), the Suzuki EPC/parts illustrations for the Splash condenser assembly, and Denso condenser documentation for late‑model TXV systems, the 2017 Suzuki Splash uses a receiver‑drier. It’s not a separate canister, it’s an integrated desiccant cartridge (filter‑drier) inside the condenser’s side tank. Some variants allow the desiccant bag to be serviced via a plug, others require replacing the condenser assembly.

On the Splash, the receiver‑drier’s job is simple but critical: it stores high‑pressure refrigerant, filters out fine debris, and removes moisture using a desiccant. That moisture control keeps the thermal expansion valve (TXV) happy and prevents acid formation and internal corrosion. For most Splash vehicles using R134a from this era, a healthy drier helps the system cool quickly and protects the compressor from a world of hurt.

Because the drier is working away in the hottest, high‑pressure part of the system, it gradually becomes saturated or contaminated. It’s not a “top up and forget” item—any time the A/C system is opened to atmosphere (hose off, condenser swap, compressor replacement, or a long leak), the drier should be renewed. Many air‑con specialists in Australia and New Zealand also treat the drier as consumable after a compressor failure, since metal fines can lodge in the desiccant and circulate later.

Typical cues that the receiver‑drier is past its prime include slow cooling at idle, frost or erratic behaviour at the TXV, or debris found in the old oil during service. While there’s no fixed kilometre interval, a practical approach for a Splash is to replace the desiccant bag (or condenser, if non‑serviceable) whenever the system is opened, and consider it proactively at around 7–10 years in hot, humid climates.

When servicing a 2017 Suzuki Splash: use new O‑rings, draw a proper vacuum with a deep hold test, add the correct PAG oil amount for any component replaced, and charge by weight. If the condenser houses a replaceable drier cartridge, fit the new desiccant last, keep it sealed until installation, and button up quickly to minimise moisture ingress. If the condenser has no service plug, don’t sweat it—simply replace the condenser with a quality unit that includes a fresh drier. That way, the Splash’s A/C performance stays crisp and the compressor stays protected.

• Replace the drier whenever the system is opened or after compressor failure.
• Use the correct oil and charge by weight for reliable cooling.
• If no service plug is present, replace the condenser (integrated drier).

FAQs

Where is the receiver‑drier on a 2017 Suzuki Splash?
On the Splash it lives inside the A/C condenser’s side tank as a desiccant cartridge. You won’t see a separate silver canister. Some versions have a small service plug for the desiccant, others need the whole condenser replaced to renew the drier.

Do you have to replace the drier when re‑gassing?
If the system hasn’t been opened and there’s no leak or component swap, a simple recover‑vacuum‑recharge doesn’t demand a new drier. But if the system’s been open to air, there’s been a leak, or a compressor/condensor/line is changed, replacing the drier is best practice.

Can the drier be changed separately from the condenser?
It depends on the condenser design fitted to the vehicle. Some Splash condensers have a removable desiccant bag accessed via a service plug. If yours doesn’t, the correct method is to replace the condenser assembly, which arrives with a fresh integrated drier.
