The Multiquip 3-13321 is a genuine OEM Radiator Hose designed for RW-3015 and KA4B series ride-on rollers. As a direct OEM replacement sourced through Multiquip's authorized parts network, this hose is manufactured to the original specifications required to maintain proper coolant flow in demanding compaction applications. DHS Equipment stocks this part to help keep your roller running at the correct operating temperature without the guesswork of sourcing a compatible substitute. Confirmed fitment includes the RW-3015 and KA4B RAMMAX roller models.
Key Features
- OEM Coolant System Integrity — Manufactured to the original pressure and temperature ratings for the RW-3015 and KA4B cooling circuit, ensuring the hose seats and seals correctly at both connection points.
- Direct-Fit Replacement — Molded to match the original routing and end dimensions, this hose connects directly to the existing fittings without trimming or adapting.
- Confirmed Fitment — Verified for RW-3015 and KA4B RAMMAX ride-on roller models within the Multiquip roller lineup.
- Sustained Engine Cooling — A sound radiator hose maintains consistent coolant circulation to the engine; a cracked or collapsed hose leads to overheating and unplanned downtime on the worksite.
- Fuel and Coolant System Safety — Proper hose integrity prevents coolant loss near hot engine components, reducing the risk of overheating events that can damage the engine block or cause unsafe operating conditions.
A radiator hose carries coolant between the engine and the radiator, allowing heat absorbed from the engine to be dissipated before the coolant cycles back through. On ride-on rollers like the RW-3015 and KA4B, the engine works hard under continuous load, making a fully intact cooling circuit essential to sustained operation. When a radiator hose cracks, softens, or fails at a connection, coolant escapes, engine temperatures rise rapidly, and the risk of serious engine damage increases significantly.
