The Multiquip 42732 Upper Radiator Hose Tier 4 is a genuine OEM component designed for HTX6H and STX6H ride-on power trowels. As a direct OEM replacement, 42732 is manufactured to the same specifications as the original part, ensuring a proper connection between the engine and radiator with no fitment guesswork. This hose is specifically rated for Tier 4 engine configurations, making it the correct choice for machines equipped with Tier 4-compliant powerplants. If you're servicing an HTX6H or STX6H, verifying this part number against your serial tag confirms you're installing the right hose for your machine's cooling circuit.
Key Features
- Genuine OEM Cooling System Integrity — Manufactured to OEM material and dimension standards for the Tier 4 cooling circuit, maintaining proper coolant flow and pressure ratings for the engine's operating range.
- Direct-Fit Tier 4 Configuration — Engineered specifically for Tier 4 engine setups on HTX6H and STX6H trowels, connecting directly to the existing hose fittings without modification to hose routing or clamp positions.
- Confirmed Fitment for HTX6H and STX6H — Verified OEM fitment for Multiquip HTX6H and STX6H hydrostatic ride-on power trowels equipped with Tier 4 engines.
- Sustained Engine Temperature Control — A properly functioning upper radiator hose maintains consistent coolant circulation between the engine and radiator, preventing overheating during extended finishing operations.
- Fuel and Coolant Resistance — OEM hose construction uses materials rated to withstand engine-bay heat cycles and coolant chemistry, resisting premature cracking, swelling, or collapse that can interrupt cooling flow.
The upper radiator hose carries hot coolant from the engine's outlet to the top of the radiator, where heat is dissipated before the coolant is recirculated. On ride-on power trowels like the HTX6H and STX6H, the engine works under sustained load during concrete finishing passes, making a reliable cooling circuit essential to avoiding thermal shutdowns. A cracked, collapsed, or leaking upper radiator hose will cause coolant loss and rapid overheating, potentially resulting in engine damage and unplanned downtime on the slab.
