The genuine XCMG 380604107 Liquid Reservoir is a high‑quality receiver‑drier designed for motor grader air conditioning systems. This OEM 380604107 reservoir stores liquid refrigerant, removes moisture, and filters contaminants to protect the A/C compressor and expansion valve.
Manufactured from extruded aluminum with a corrosion‑resistant coating, it features a sight glass for refrigerant level inspection and a pressure safety vent.
Engineered for XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders, this liquid reservoir is a direct replacement for original equipment with identical mounting brackets and port connections.
The integrated desiccant bag (molecular sieve XH‑7) absorbs residual moisture, preventing ice formation in the expansion valve. A clogged or saturated reservoir causes poor cooling, compressor cycling, and potential system corrosion.
Replacing a failed liquid reservoir with genuine XCMG 380604107 restores proper refrigerant flow, removes acids, and ensures long‑term A/C reliability in hot, humid operating environments.
This component is also used in heavy‑duty trucks and off‑road equipment. XCMG 380604107 guarantees OE fit, filtration efficiency, and moisture absorption capacity.

The 380604107 liquid reservoir stores excess liquid refrigerant, ensuring a steady supply to the expansion valve under varying load conditions. It also separates vapor from liquid.
The internal desiccant removes moisture that would otherwise freeze in the expansion valve or react with refrigerant to form corrosive acids. Acidic refrigerant damages the compressor, condenser, and evaporator.
The filter screen catches debris such as metal particles from a failing compressor, preventing blockage of the expansion valve and protecting the entire system.
Replacing a saturated or blocked reservoir with genuine XCMG 380604107 restores proper moisture control, filtration, and refrigerant flow, extending the life of the A/C components.
Each 380604107 reservoir contains a replaceable desiccant bag filled with molecular sieve XH‑7, which has high water absorption capacity and low dust generation.
The integrated 40‑micron polyester screen filter stops particles without restricting refrigerant flow. A sight glass with moisture indicator changes from green to yellow when the desiccant is saturated.
The aluminum body is epoxy‑coated inside and out to resist corrosion from external salt spray and internal acidic oil.
XCMG tests every reservoir for burst pressure at 10.5 MPa and for leakage using helium mass spectrometry. The desiccant is factory‑sealed in a moisture‑proof bag to ensure dryness at installation.
To replace a saturated or leaking liquid reservoir, recover the refrigerant using an A/C recovery machine. Disconnect the battery to avoid accidental clutch engagement.
Remove the electrical connector (if pressure switch equipped) and the mounting bolts. Unthread the inlet and outlet fittings using a backup wrench.
Transfer any pressure sensor or switch to the new 380604107 reservoir using fresh O‑rings lubricated with PAG oil. Install the reservoir with new O‑rings and torque fittings to 25 Nm.
Evacuate the A/C system for at least 45 minutes, then recharge with the exact refrigerant weight. Start the engine, turn on A/C, and observe the sight glass for bubbles – clear glass indicates proper charge.
Always replace the liquid reservoir when the compressor or condenser is replaced, and after any major system contamination. Keep a genuine spare 380604107 for summer A/C failures.
Sight glass shows yellow or brown color (moisture contamination), visible oil wetness or corrosion on the body, A/C system cycling rapidly, and insufficient cooling even with correct refrigerant charge.
Also, bubbles in the sight glass at steady state (indicating low charge or restriction), and a noisy expansion valve. Replace the reservoir immediately when moisture is detected.
Inspect the liquid reservoir annually or every 1,000 operating hours. Check the sight glass for color change and external corrosion. Replace if the moisture indicator is yellow or the body shows pitting.
XCMG recommends replacing the 380604107 reservoir every 3‑4 years or every 4,000 operating hours, whichever comes first. In humid or coastal environments, replace every 2 years.
When the system is opened for any repair, always install a new reservoir – the desiccant quickly saturates when exposed to ambient air for more than 15 minutes.
Keep the original plastic caps on until installation to protect the desiccant from moisture. Do not leave the new reservoir uncapped for more than 5 minutes.
Genuine XCMG 380604107 liquid reservoirs are backed by a 12‑month warranty. Regional warehouses: Houston (USA), Rotterdam (Netherlands), Dubai (UAE), and Shanghai (China).
Standard air freight delivers within 3‑7 business days worldwide. Express 24‑48 hour shipping available for urgent A/C repairs. Bulk orders (10+ units) receive volume discounts.
Aftermarket reservoirs often use inferior desiccants (silica gel) that break down and clog the system, or lack the moisture indicator. Genuine XCMG 380604107 uses molecular sieve XH‑7 for maximum water absorption and filter integrity.
Do not attempt to reuse an old reservoir – desiccant cannot be regenerated. A clogged or saturated reservoir can cause compressor failure and expensive repairs.
