Multiquip 68900479 Upper Radiator Hose Lt12

The Multiquip 68900479 Upper Radiator Hose Lt12 is a genuine OEM component designed for HTX44Y4, HTX44Y5, and HTXD6i hydrostatic ride-on power trowels. Sourced directly from Multiquip, this hose meets the exact routing, diameter, and pressure specifications required for proper coolant flow on these machines. Confirmed fitment across the HTX heavy-duty hydrostatic trowel series means you can order with confidence that 68900479 will install correctly without modification. DHS Equipment stocks this OEM part to keep your trowel cooling system operating as engineered.

Key Features

• OEM Coolant Path Integrity — Manufactured to the exact inner diameter, length, and bend profile required for correct upper radiator routing on HTX series trowels, ensuring full coolant flow without restriction or leakage.
• Direct-Connect Replacement — Engineered to seat precisely onto the radiator and engine coolant ports of the HTX44Y4, HTX44Y5, and HTXD6i, allowing a straightforward hose-clamp installation with no trimming or adapter fittings.
• HTX Series Compatibility — Verified fitment for HTX44Y4, HTX44Y5, and HTXD6i Whiteman hydrostatic ride-on power trowels; always cross-reference part number 68900479 against your machine model before ordering.
• Sustained Engine Temperature Control — A properly routed upper radiator hose keeps coolant circulating between the engine and radiator at the correct rate; a cracked or collapsed hose can cause rapid overheating and unplanned engine shutdown mid-pour.
• Pressure and Heat Resistance — As a genuine OEM hose, this part is constructed from materials rated for the operating temperatures and system pressures present in the HTX trowel cooling circuit, resisting premature softening, cracking, or collapse.

The upper radiator hose carries hot coolant from the engine outlet to the top of the radiator, where heat is dissipated before the cooled fluid is returned to the engine. On a heavy-duty ride-on trowel like the HTX series, the engine works under sustained load for long finishing runs, making a reliable cooling circuit essential to preventing thermal damage. When this hose deteriorates — through cracking, swelling, or hose clamp failure — coolant loss occurs quickly, and unchecked overheating can cause serious engine damage within minutes of a breach.
