The Multiquip 43140-21 is a genuine OEM Radiator Subassembly designed for the STXDF series ride-on power trowels. As a direct Multiquip OEM component, this part is sourced to the original design specification, ensuring it integrates correctly with the cooling system architecture of STXDF equipment. Please note that part number 43140-21 has been designated no longer available (NLA) — a updated subassembly or superseding assembly may apply, so contact DHS Equipment to confirm the current service path before ordering. Verifying the correct replacement against your machine's serial number and service documentation is strongly recommended.
Key Features
- Genuine OEM Cooling System Component — Sourced directly from Multiquip to the original design specification, ensuring correct thermal capacity and connection geometry for the STXDF cooling circuit.
- Direct Subassembly Replacement — Supplied as a subassembly, meaning core mounting points, inlet/outlet fittings, and bracket provisions are pre-configured for drop-in service on compatible STXDF units.
- STXDF Series Fitment — Confirmed for Whiteman STXDF ride-on power trowels; always cross-reference your machine's serial number and parts manual before ordering.
- Maintains Proper Engine Operating Temperature — A correctly functioning radiator subassembly keeps the engine within its designed temperature range, preventing heat-related power loss and premature wear during extended finishing runs.
- NLA Status — Verify Before Ordering — Part 43140-21 is no longer available as originally cataloged; DHS Equipment can identify the current superseding part or assembly to fulfill your service requirement.
The radiator subassembly is the primary heat-exchange unit in the engine's liquid cooling system. It circulates coolant through a network of tubes and fins, transferring heat absorbed from the engine block into the surrounding air to keep operating temperatures within a safe range. On a ride-on trowel like the STXDF — which runs under sustained load during large slab finishing — a degraded or leaking radiator subassembly can lead to overheating, automatic engine shutdown, and costly delays on the pour.
