The Multiquip 23312 Upper Radiator Hose is a genuine OEM replacement designed for HHXD5 and HHXD5-ES Whiteman ride-on power trowels. As a direct OEM component, part 23312 is manufactured to the same specifications as the original, ensuring a proper connection between the engine and radiator without modification. This hose is confirmed to fit both the HHXD5 and HHXD5-ES models, making it the straightforward choice when the original hose shows cracking, softening, or coolant seepage.
Key Features
- Genuine OEM Construction — Manufactured to the same material grade and wall thickness as the original hose, maintaining correct coolant flow and pressure tolerance for the HHXD5 engine cooling circuit.
- Direct-Fit Upper Hose — Matches the original hose routing, diameter, and end fittings so it seats properly on the engine outlet and radiator inlet with standard hose clamps.
- Confirmed Fitment — Verified for HHXD5 and HHXD5-ES Whiteman ride-on power trowels, so you can order with confidence using part number 23312.
- Cooling System Integrity — A correctly fitted upper radiator hose keeps coolant circulating at the right pressure; a cracked or swollen hose risks overheating the engine mid-pour and forcing a costly shutdown.
- Sourced from Multiquip — Supplied as a genuine Multiquip OEM part through DHS Equipment, ensuring you receive the correct component backed by the manufacturer.
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 cycles back through the engine. It is a critical link in the cooling system — if the hose collapses, leaks, or loses its seal at either end, coolant pressure drops and the engine temperature rises rapidly. On a ride-on trowel working through a concrete finishing run, an overheating event can damage the engine and interrupt work that cannot simply be paused. Replacing a worn hose at the first sign of deterioration is one of the simplest ways to protect the machine's engine.
