Multiquip 203522 Radiator Assembly

The Multiquip 203522 Radiator Assembly is a genuine OEM component designed for the C30HDGA concrete pump. As a direct OEM replacement, this assembly is sourced from Multiquip and built to the same standards as the original unit installed at the factory, ensuring a correct, trouble-free installation. If you are maintaining or restoring a C30HDGA, the 203522 is the correct radiator assembly for the job.

Key Features

• Genuine OEM Cooling Capacity: — Engineered to the exact core dimensions and coolant flow specifications of the original C30HDGA radiator, maintaining proper engine operating temperature under continuous pumping loads.
• Direct Drop-In Fit: — Matches original mounting points, hose connections, and bracket positions on the C30HDGA, allowing straightforward installation without reworking fittings or supports.
• Confirmed C30HDGA Fitment: — Verified for Mayco C30HDGA concrete pumps; cross-reference part number 203522 before ordering to confirm compatibility with your unit.
• Protects Engine Longevity: — A fully functioning radiator keeps coolant temperatures in range during high-demand pumping cycles, preventing overheating events that can cause costly engine damage or unplanned shutdowns.
• Genuine Multiquip OEM Part: — Supplied through the authorized Multiquip parts network, so you receive the same assembly specified for this machine — not a generic substitute with unknown core quality.

The radiator assembly is the heart of the engine cooling system on a concrete pump. It transfers heat away from the engine coolant by passing it through a finned core where airflow dissipates the thermal energy, returning cooled fluid back to the engine. On a machine like the C30HDGA that operates under sustained load during pumping operations, a degraded or failed radiator leads rapidly to overheating, which can trigger automatic shutdowns, warp cylinder heads, or cause permanent engine damage. Keeping this assembly in serviceable condition is essential to consistent, uninterrupted pump operation.
