Parts for your 2017 Mitsubishi Asx-Receiver driers

2017 Mitsubishi ASX receiver‑drier: what it does and when to replace it

Based on technical sources including the Mitsubishi Motors Service Manual for ASX/RVR (2016–2018, Group 55A HVAC), plus OE supplier guidance from DENSO and Sanden on late‑model condenser designs, the 2017 Mitsubishi ASX uses a receiver‑drier. It’s integrated into the A/C condenser (often via a replaceable desiccant cartridge), paired with a thermostatic expansion valve. So yes—this model does have a receiver‑drier, it’s just not a separate under‑bonnet canister like older cars.

On the ASX, the receiver‑drier’s job is to store liquid refrigerant and keep moisture and debris out of the system. The desiccant inside absorbs water vapour, protecting the compressor, expansion valve and internals from corrosion, acid formation and freeze‑up. With the drier built into the condenser’s side tank, the system stays compact and efficient—exactly how DENSO’s parallel‑flow condenser and Mitsubishi’s HV/AC layout are designed to work.

There’s no fixed kilometre‑based service interval for a receiver‑drier on the 2017 ASX. Instead, replacement is recommended any time the system is opened to atmosphere (for example, after hose, condenser or compressor work), after a compressor failure, or if there’s known contamination. That lines up with Mitsubishi’s workshop guidance and common industry practice from OE suppliers. In many ASX variants, the desiccant “bag” can be swapped out of the condenser, where a separate kit isn’t available, the correct repair is to replace the condenser assembly.

Good workshop practice matters here. Fit new O‑rings lubricated with the correct PAG oil, evacuate the system long enough to boil off moisture (usually 30–45 minutes), and then recharge with the refrigerant specified on the under‑bonnet label (AU/NZ ASX models are typically R‑134a). If the compressor has been replaced, add the specified oil quantity and always renew the receiver‑drier/desiccant at the same time to protect the fresh components.

If the air‑con is a bit weak, the sight glass isn’t a guide on this model (there usually isn’t one). Instead, look for signs like pressure imbalance on gauges, a blocked expansion valve, or moisture‑related frosting. A fresh desiccant and a proper vacuum/recharge can restore performance and keep the ASX’s cabin cool through an Aussie summer or a humid Kiwi spring.

• FAQs

Does the 2017 ASX have a receiver‑drier or an accumulator?
It has a receiver‑drier integrated into the condenser, working with a thermostatic expansion valve. Accumulators are used on orifice‑tube systems, which the ASX doesn’t use.

When should the receiver‑drier be replaced on a 2017 ASX?
Replace it whenever the A/C system is opened, after compressor failure, or if moisture/contamination is suspected. It isn’t a routine time‑based item, but proactive replacement during major A/C work is cheap insurance.

Can the receiver‑drier be changed without replacing the condenser?
On many 2017 ASX variants, yes—the desiccant cartridge can be replaced. If a service kit isn’t available for a particular condenser, the recommended fix is to replace the condenser assembly.
