Parts for your 2004 Mitsubishi Lancer-Receiver driers

Receiver-drier on a 2004 Mitsubishi Lancer

Yes, the 2004 Mitsubishi Lancer (CH/CS series) uses a receiver‑drier in its air‑conditioning system. This model runs a thermal expansion valve (TXV) setup, which pairs with a receiver‑drier on the high‑pressure side—often mounted to, or integrated into, the condenser side tank. Technical sources that describe this include Mitsubishi’s Lancer CH/CS Workshop Manual (Heater & Air Conditioning/Group 55 diagrams and service procedures), the Mitsubishi ASA electronic parts catalogue (A/C components breakdown for CS/CH), and major HVAC parts catalogues from OE suppliers (e.g., DENSO) and Australian aftermarket distributors that list a dedicated receiver‑drier for 2003–2007 Lancer models.

On this Lancer, the receiver‑drier’s job is to dry and filter the refrigerant, catch debris, and act as a small reservoir so the TXV gets clean, vapour‑free liquid refrigerant. That keeps cabin temps consistent, protects the compressor, and helps the system cool properly on scorching Aussie and Kiwi summer days.

Servicing advice is straightforward. A receiver‑drier is a consumable moisture trap: once the system’s been opened to air (for a hose, condenser, or compressor swap), the desiccant starts absorbing moisture and can’t be fully recovered by vacuum. That’s why it’s best practice to replace the drier any time the system is opened, after compressor failure, or if the A/C has been inoperative or empty for a while. On many CH/CS cars the drier is part of, or bolts to, the condenser, some have a replaceable desiccant cartridge accessed via a plug on the condenser tank. If that plug’s seized or the tank’s corroded, a new condenser is often the cleaner fix.

Look out for weak cooling at idle, rapid cycling, or contamination found during service—these can point to a saturated or blocked drier. When replacing it, a licensed A/C technician should evacuate and recharge with the specified R134a charge and the correct PAG oil for the compressor. Always use new O‑rings, torque the fittings properly, and pressure/leak‑test before re‑gassing. Following the workshop manual specs and using ARCtick‑licensed services in Australia (or a licensed technician in NZ) will keep the Lancer’s A/C reliable for years and thousands of kilometres.

• Where is the receiver‑drier on a 2004 Lancer?
  On most CH/CS Lancers it’s attached to, or integrated with, the condenser on the front of the car. You’ll typically find it on one side of the condenser behind the bumper. Some versions use a replaceable desiccant cartridge inside the condenser tank, accessed via a service plug.
• When should it be replaced?
  Replace the receiver‑drier any time the system is opened to the atmosphere, after compressor failure, or if the A/C has been empty or unused for a long stretch. It’s also smart to change it if there’s evidence of moisture or debris during routine A/C service.
• Can it be changed without re‑gassing?
  No. The A/C circuit must be properly recovered, opened to replace the drier, then evacuated and recharged to the specified R134a amount. This should be done by an ARCtick‑licensed (AU) or appropriately licensed (NZ) technician.
