Multiquip 68900480 Lower Radiator Hose

The Multiquip 68900480 Lower Radiator Hose is a genuine OEM component designed for HTX44Y4, HTX44Y5, and HTXD6i hydrostatic ride-on power trowels. Sourced directly from Multiquip, this hose is built to the exact dimensions and material specifications of the original part, ensuring a correct connection between the radiator and the engine cooling circuit. Verified fitment across the HTX series means you can order with confidence and get your trowel back on the slab without guesswork.

Key Features

• OEM-Grade Coolant Hose Construction — Manufactured to the same pressure rating, inner diameter, and bend profile as the original, maintaining full coolant flow capacity throughout the cooling circuit.
• Exact-Match Lower Radiator Position — Engineered to seat correctly at the lower radiator outlet, with matching end fittings that clamp and seal to OEM torque specs without trimming or modification.
• Confirmed Fitment for HTX Series Trowels — Directly compatible with HTX44Y4, HTX44Y5, and HTXD6i hydrostatic ride-on power trowels, covering both Y4 and Y5 Yanmar diesel variants plus the HTXD6i configuration.
• Cooling System Integrity — A sound lower radiator hose keeps coolant circulating at the correct pressure and volume, protecting the engine from overheating during extended finishing runs.
• Fuel System Safety Compliance — A cracked or collapsed lower radiator hose can cause rapid coolant loss and engine shutdown mid-pour; replacing it with a genuine OEM hose restores full system integrity.

The lower radiator hose carries coolant from the bottom of the radiator back to the engine water pump, completing the return leg of the cooling loop. When this hose cracks, swells, or collapses internally, coolant flow is restricted or lost entirely, causing engine temperatures to spike and potentially leading to overheating damage or an unplanned machine shutdown. Replacing a worn hose with a properly rated OEM unit restores the sealed, pressurized cooling circuit the engine depends on to run safely at full load.
