The Multiquip 79000448 Radiator STX is a genuine OEM radiator designed for the STX series hydrostatic ride-on power trowels, including the STXD6i and STX55Y6. As a direct Multiquip OEM component, the 79000448 is manufactured to the same specifications as the original unit, ensuring a correct fit into the existing cooling system without guesswork or modification. Verified fitment covers STXD6i and STX55Y6 machines, making this the straightforward replacement choice for operators and service technicians working on these super-sized hydrostatic trowels.
Key Features
- Genuine OEM Cooling Capacity: — Engineered to the exact thermal dissipation specification of the original radiator, maintaining proper engine operating temperatures under continuous troweling loads.
- Drop-In Fitment for STX Series: — Matches the original mounting points, hose connections, and core dimensions for the STX platform, allowing a straightforward swap during scheduled service or emergency repair.
- Confirmed Compatibility: — Fits STXD6i and STX55Y6 hydrostatic ride-on power trowels; verify your model code before ordering.
- Protects Engine and Hydraulic System Longevity: — A fully functional radiator keeps the engine and hydraulic fluid temperatures in range, preventing heat-related wear on internal components during extended finishing runs.
- Fuel and Coolant System Safety: — A compromised radiator risks overheating that can cause engine shutdown or damage on an active pour; replacing with a verified OEM unit restores safe thermal management.
The radiator is the core of the engine's liquid cooling system on STX series ride-on trowels. It circulates coolant through the engine block to absorb heat generated during operation, then dissipates that heat through the radiator core before the coolant loops back. On heavy-duty hydrostatic machines like the STXD6i and STX55Y6, which run demanding diesel engines under sustained load, a worn or leaking radiator can lead to rapid overheating, forcing a costly shutdown mid-pour or risking serious engine damage. Replacing a failing unit promptly with the correct OEM part keeps the cooling system performing as intended.
