The Wacker Neuson Radiator is a genuine OEM component designed for CRT48 and CT48 series concrete trowels, including the CRT48-34V, CRT48-31V, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, CRT48-31V-ES-E, and CT48-13A-V models. Sourced directly from Wacker Neuson, this radiator meets the same specifications as the original unit installed at the factory. Direct-replacement fitment means the installs into your existing cooling system mounts and connections without modification. If your trowel is running hot or showing signs of coolant system failure, replacing the radiator with the correct OEM part is the most dependable path to restoring full operation.
Key Features
- Genuine OEM Cooling Capacity: — Built to the same core size, tank volume, and flow rating as the original, ensuring the engine stays within its designed operating temperature range under continuous troweling loads.
- Drop-In Fitment for CRT48 and CT48 Trowels: — Engineered to match the original mounting points, hose connections, and clearances across the CRT48-34V, CRT48-31V, CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, CRT48-31V-ES-E, and CT48-13A-V platforms.
- Direct Wacker Neuson OEM Part: — Part number 5000158335 is an authorized Wacker Neuson replacement, giving you full confidence in part identity and application accuracy before you order.
- Protects Engine Longevity: — A functioning radiator keeps coolant temperatures stable during extended finishing runs; a cracked or blocked radiator allows heat to build rapidly, risking engine damage and unplanned shutdowns on the slab.
- Broad CRT48 Series Coverage: — A single part number covers multiple CRT48 and CT48 configurations, making 5000158335 a practical stock item for fleets running 48-inch Wacker Neuson trowels.
The radiator is the central component of the engine's liquid cooling circuit. It dissipates heat absorbed by the coolant as it circulates through the engine block, passing the hot coolant through a network of fins and tubes where airflow carries the heat away. On a ride-on or walk-behind concrete trowel operating under sustained load — especially in warm conditions — the radiator works continuously to prevent the engine from overheating. When the radiator leaks, becomes blocked with debris, or suffers physical damage, coolant temperature climbs quickly, triggering shutdowns or, in severe cases, causing internal engine damage that far exceeds the cost of the radiator itself.
