Parts for your 2006 Mitsubishi Pajero-Receiver driers

2006 Mitsubishi Pajero receiver‑drier: what it does and when to replace it

Technical references confirm the 2006 Mitsubishi Pajero (V60/V70 series, including models with optional rear air) uses a high‑side receiver‑drier in its R134a air‑conditioning system. The Mitsubishi Workshop Manual for Group 55 (HVAC) diagrams a thermal expansion valve (TXV) system with a receiver‑drier ahead of the TXV, and Mitsubishi ASA/EPC parts listings show a “receiver assembly, air conditioner” applicable to these models. Aftermarket catalogues from A/C suppliers also list a receiver‑drier or condenser‑integrated desiccant for the 2006 Pajero, reinforcing that this component is fitted.

On this Pajero, the receiver‑drier does three jobs: it stores a small volume of liquid refrigerant, filters out debris, and—most critically—removes moisture with a desiccant. Keeping water out prevents corrosive acids and ice from forming, both of which can wreck compressors and block TXVs. Depending on variant and condenser type, the drier may be a separate canister mounted near the condenser, or a replaceable desiccant bag integrated into the condenser side tank.

Servicing advice is straightforward. Any time the system is opened (hose off, condenser or compressor swapped, stone‑damaged condenser, or a leak repair), the receiver‑drier should be renewed. If the compressor has failed, a new drier is non‑negotiable, as it traps shrapnel and absorbs moisture introduced during the repair. In high‑humidity climates, many technicians treat the drier as a 5–7 year preventative item, especially on vehicles that see off‑road or coastal use.

• Tell‑tales of a drier past its best: poor cooling after a recent leak repair, frosting at or just before the TXV, elevated high‑side pressures, or contamination found in the removed old part.
• Best practice: replace all O‑rings, lubricate with the correct oil (PAG for R134a as specified), torque fittings correctly, evacuate under deep vacuum for 30–45 minutes, then recharge by weight to the factory spec.

For Pajeros with a condenser‑integrated drier, either replace the desiccant cartridge if serviceable, or fit a new condenser assembly where the drier isn’t separately replaceable—check by VIN or condenser label. Because handling refrigerant requires a licence in Australia (ARCtick) and regulated practice in New Zealand, this job is best left to a qualified air‑con technician.

• Does the 2006 Pajero have a separate receiver‑drier or one built into the condenser?

Both configurations exist across the V60/V70 range. Many vehicles have a separate canister beside the condenser, some later or replacement condensers use an internal desiccant cartridge. The easiest way to tell is by visual check: look for a small aluminium canister plumbed into the high‑side line near the condenser. If absent, it’s likely condenser‑integrated.

• How often should the receiver‑drier be replaced on a 2006 Pajero?

Replace it whenever the A/C circuit is opened, after a compressor or condenser failure, or if the system has been flat or exposed to atmosphere. As preventative maintenance in humid conditions, many workshops recommend replacement every 5–7 years to protect the TXV and compressor.

• Where is the receiver‑drier located on this model?

Typically at the front of the vehicle near the condenser—often on the right‑hand side—mounted upright with high‑pressure lines attached. On variants with an integrated design, it sits inside the condenser’s side tank and is accessed by replacing the cartridge (if serviceable) or the condenser assembly.
