The Multiquip 21522-001 Radiator Mount is a genuine OEM component designed for HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5 heavy-duty hydrostatic ride-on power trowels. As a direct OEM replacement, this mount is built to the same specifications as the original part, ensuring correct positioning and secure retention of the radiator within the machine's cooling system. Verified fitment across the HTX44 series means you can order with confidence that this part will install as intended. DHS Equipment supplies this part direct, backed by Multiquip's OEM parts program.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original specifications, delivering the same dimensional tolerances and material grade as the part it replaces on HTX44 series trowels.
- Secure Radiator Retention — Correctly locates and anchors the radiator in the chassis, preventing vibration-induced movement during operation that can stress cooling hoses and fittings.
- Confirmed HTX44 Series Fitment — Directly compatible with HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5 hydrostatic ride-on power trowels — no adaptation or modification needed.
- Cooling System Integrity — A properly mounted radiator maintains consistent coolant flow and engine temperature, protecting the Yanmar and Kubota diesel engines in the HTX44 lineup from heat-related stress.
- Genuine OEM Part Number — Part number this part is the exact Multiquip OEM reference, removing guesswork when sourcing a replacement and ensuring you receive the correct component.
The radiator mount is a structural bracket that secures the radiator to the machine's frame, keeping it correctly aligned with the engine's cooling circuit. Without a sound mounting point, the radiator is subject to vibration and movement during troweling operations, which can loosen hose connections, crack fittings, and ultimately lead to coolant loss and engine overheating. Replacing a damaged or deteriorated mount restores the stability the cooling system depends on to regulate engine temperature through extended finishing cycles.
