The Multiquip 42115 HTX Lower Radiator Hose is a genuine OEM Lower Radiator Hose designed for the HTXG6DF heavy-duty hydrostatic ride-on power trowel. As an authentic Multiquip OEM component, part 42115 is manufactured to the exact dimensions and material specifications of the original, ensuring a correct, leak-free connection between the radiator and the engine cooling circuit. This hose is confirmed for the HTXG6DF and is a direct service replacement for machines showing cracking, softening, or coolant seepage at the lower hose. DHS Equipment stocks genuine Multiquip OEM parts so you can get your trowel back on the slab without compromise.
Key Features
- Genuine OEM Coolant Path Integrity — Manufactured to the original hose profile and wall thickness, maintaining full coolant volume and pressure through the lower circuit.
- Exact-Fit Routing for HTXG6DF — Molded to the precise routing geometry of the HTX series engine bay, seating correctly on OEM hose barbs without stretching or kinking.
- HTXG6DF Trowel Compatibility — Verified fitment for the Multiquip HTXG6DF heavy-duty hydrostatic ride-on power trowel series.
- Heat and Pressure Resistance — The lower radiator hose handles sustained engine operating temperatures and coolant system pressure, resisting collapse under suction from the water pump.
- Cooling System Safety — A failed or deteriorated lower radiator hose can cause rapid coolant loss and engine overheating; replacing with the correct OEM hose restores proper thermal protection for the engine.
The lower radiator hose carries cooled coolant from the bottom of the radiator back to the engine water pump, completing the continuous loop that pulls heat away from the engine. Unlike the upper hose, the lower hose operates under suction from the water pump, which means a hose that has softened or collapsed internally can restrict coolant flow even before an external leak is visible. On a ride-on trowel like the HTXG6DF, where the engine works hard in tight finishing cycles, a degraded lower radiator hose can allow engine temperatures to climb quickly, risking costly engine damage if not caught early.
