Shacman H3000 AC Body Assembly (M3000S-Water Valve External)

4010106/Air Conditioning Unit Assembly (M3000S/External Water Valve)

This variant of the air conditioning unit assembly is designed for the M3000S chassis with an external water valve. It includes a high‑efficiency evaporator core with enhanced fin density for superior heat transfer. The expansion valve is factory‑set for R134a refrigerant, ensuring optimal cooling performance. The housing is equipped with mounting brackets that match the original firewall holes, simplifying installation. This unit is tested for leak integrity and airflow, guaranteeing reliable operation from the first start.

4010758/Air Conditioning Unit Assembly (M3000S/External Water Valve)

This second variant offers the same core functionality but may feature slight differences in connector orientation or insulation thickness to accommodate different production years or accessory configurations. It is fully interchangeable with the 4010106 variant, and both share the common part number DZ15221842326. This assembly includes the same high‑quality evaporator, expansion valve, and durable housing, ensuring consistent cooling capacity and reliability. It is ideal for direct replacement of the original unit, with all necessary seals and O‑rings included.

Common Features and Benefits

Both variants are manufactured with the same rigorous quality control processes. The aluminum evaporator cores are pressure‑tested to withstand operating pressures up to 3.5 MPa. The expansion valves are calibrated to provide superheat within ±1°C, ensuring efficient cooling without evaporator freezing. The housings are made from UV‑stabilized materials that resist cracking and warping over time.

Installation Compatibility

The assembly is designed to be a direct replacement for the original factory unit. It uses the same mounting points, refrigerant line connections, and electrical connectors. The included O‑rings are pre‑lubricated with refrigerant oil to ensure a leak‑free seal. Installation can be completed with standard hand tools, and no modifications to the vehicle’s wiring or plumbing are required.

Our Shacman H3000 AC Body Assembly (M3000S‑Water Valve External) is a genuine OEM unit, guaranteeing exact fitment, refrigerant compatibility, and cooling capacity. Each assembly is factory‑tested for leaks and airflow, ensuring that your truck’s air conditioning system operates at its designed efficiency. By choosing genuine, you avoid the risks of poor performance and premature failure associated with aftermarket copies.

The Shacman H3000 AC Body Assembly (M3000S‑Water Valve External) is engineered for quick, hassle‑free installation. The housing aligns perfectly with the existing mounting points, and the refrigerant connections use standard O‑rings that are included in the kit. This reduces installation time and minimizes downtime, getting your truck back to a cool, comfortable state swiftly.

Reliability is the cornerstone of this assembly. The aluminum evaporator is brazed with a non‑corrosive flux, and the expansion valve is calibrated to maintain stable superheat under varying loads. The housing is designed to prevent condensate from entering the cab, reducing the risk of mold and mildew. Choose our genuine part for long‑lasting, trouble‑free cooling.

We maintain a comprehensive stock of the Shacman H3000 AC Body Assembly (M3000S‑Water Valve External) to ensure rapid dispatch. Our competitive pricing and worldwide shipping make it easy to keep your fleet’s A/C systems in top condition. With our dedicated support, you can trust that you are getting the right part for your specific truck model.

The Shacman H3000 AC Body Assembly (M3000S‑Water Valve External) is typically located behind the dashboard, mounted on the firewall. Replacement requires evacuation of the refrigerant system, disconnection of the liquid and suction lines, and removal of the mounting bolts. Our assembly includes new O‑rings and a desiccant bag (if applicable) to ensure a complete, professional installation. Always use a certified A/C service machine to recover and recharge refrigerant.

When replacing the unit, inspect the expansion valve for any debris or blockage. Our assembly comes with a pre‑calibrated valve, but if you are reusing the old one, ensure it is clean and properly adjusted. The evaporator core should be free of dirt and fins straightened. Our genuine assembly guarantees a clean, ready‑to‑install core that maximizes airflow and heat exchange.

Regular maintenance of the A/C system includes checking the cabin air filter, inspecting the condenser for debris, and monitoring the sight glass for refrigerant level. The Shacman H3000 AC Body Assembly (M3000S‑Water Valve External) is designed to last the lifetime of the vehicle, but if you notice reduced cooling or unusual noises, it may be time to replace the unit. Our genuine part restores the original cooling capacity, ensuring driver comfort on every trip.

For fleet operators, standardizing on the Shacman H3000 AC Body Assembly (M3000S‑Water Valve External) simplifies parts management and ensures consistent cooling performance across all trucks. Our assembly is compatible with both 4010106 and 4010758 variants, so you only need one part number (DZ15221842326) to order either. This reduces the risk of ordering errors and keeps your inventory lean.

The assembly is designed to work with R134a refrigerant, but it is also compatible with R1234yf with the appropriate oil and service fittings. However, we recommend using the refrigerant specified for your vehicle. Our unit’s expansion valve is optimized for the operating pressures of R134a, ensuring maximum cooling efficiency and compressor longevity.

If you are upgrading from a manual to an automatic climate control system, this assembly is compatible with both, as the expansion valve is electrically controlled in some configurations. Our unit includes the necessary wiring harness connector for easy integration. Consult the vehicle’s service manual for specific wiring details.

The housing is designed with integrated drain channels to prevent water accumulation. When installing, ensure the drain hose is correctly attached and not kinked, as this could cause condensation to back up into the cab. Our assembly includes a new drain hose fitting and grommet for a secure, leak‑free connection.

For the best results, we recommend replacing the receiver‑drier and the expansion valve simultaneously when replacing the AC body assembly. However, our unit includes a new expansion valve and O‑rings, so you only need to replace the drier separately if required. This ensures a complete system overhaul, restoring your truck’s A/C to like‑new condition.
