Parts for your 2022 Toyota C-hr-Receiver driers

2022 Toyota C‑HR receiver‑drier: what it is, where it lives, and when to service it

Short answer, yes — the 2022 Toyota C‑HR does use a receiver‑drier function. It’s not a separate silver canister like older setups, though. On this model the receiver‑drier (desiccant and filter) is integrated into the A/C condenser’s side tank. That’s confirmed in Toyota’s Repair Manual for the C‑HR (AX10/AX50) which specifies a sub‑cool condenser with an internal desiccant, and in the Toyota Electronic Parts Catalogue (EPC) which lists the “Condenser Assy, Cooler” along with a serviceable “Filter, Cooler Dryer (Desiccant)” kit in many markets. DENSO’s condenser documentation describes the same integrated desiccant bag design, and SAE guidance around modern TXV systems and R‑134a/R‑1234yf supports this condenser‑with‑receiver architecture.

On the 2022 C‑HR, the receiver‑drier’s job is to mop up moisture, trap fine debris, stabilise liquid refrigerant supply to the TXV, and protect the compressor. Because it’s built into the condenser, there’s no stand‑alone “drier can” to spot under the bonnet. Instead, techs access a service plug or cap on the condenser to replace the desiccant bag on applicable variants — otherwise the whole condenser is replaced.

Is it a routine service item? Not usually. Toyota’s service information and industry practice say the desiccant should be renewed when the system has been opened to atmosphere, after compressor failure, if the condenser is replaced, or when contamination is suspected. It’s also wise if the vehicle has had a front‑end repair where the A/C loop was disturbed.

• Replace the desiccant bag (or condenser) any time the system has been open for more than a short while.
• Always use new O‑rings, evacuate thoroughly, and recharge by weight with the refrigerant shown on the under‑bonnet label (R‑134a or R‑1234yf, depending on market).
• Match the correct compressor oil type and quantity specified for the C‑HR, don’t mix oils.
• Pressure‑test with dry nitrogen and use an approved leak detector before re‑gassing.

Symptoms that point to a saturated or restricted drier include weak cooling at idle, high head pressures, a noisy or stressed compressor, or frost/temperature drop across the condenser outlet. A/C performance checks, pressure readings, and line temperature comparisons will guide the call. If the desiccant is serviceable separately on your market’s condenser, it’s a tidy, cost‑effective fix, if not, swapping the condenser assembly is the go.

Popular questions

Where is the receiver‑drier on a 2022 C‑HR?

It’s built into the condenser on the front of the car, just ahead of the radiator. There’s no separate canister, the desiccant bag sits inside the condenser’s side tank. Access depends on bumper and upper support removal for safe servicing.

When should the receiver‑drier be replaced on a C‑HR?

Replace the desiccant (or condenser) whenever the A/C system has been open, after a compressor failure, or if diagnostics show moisture/contamination or internal restriction. It’s not a time‑based item, it’s condition‑based and done during related A/C repairs.

Can the desiccant be changed without replacing the condenser?

On many C‑HR variants, yes — Toyota supplies a service desiccant kit that fits into the condenser. Some markets or condenser versions may require replacing the entire condenser. Your VIN and local parts catalogue will confirm what’s fitted.
