The Husqvarna 505135901 Radiator FS8400 1-Pass is a genuine OEM cooling component designed specifically for the FS8400 floor saw.

DHS Equipment supplies this part to help keep your floor saw performing at full capacity on the job.
Key Features
- OEM Cooling Capacity — Engineered to Husqvarna's exact thermal transfer specifications for the FS8400, maintaining the correct coolant flow rate and heat dissipation your engine depends on.
- Direct OEM Replacement — Matches the original mounting points, inlet and outlet connections, and core dimensions of the FS8400, allowing straightforward installation without modification.
- FS8400 Floor Saw Fitment — Sourced and verified for the FS8400 floor saw, so you can cross-reference part number 505135901 against your parts diagram with confidence.
- Protects Engine Longevity — A properly functioning radiator keeps coolant temperatures stable during extended cutting runs, protecting the engine from heat-related wear and unplanned shutdowns.
- Genuine Husqvarna Quality — Manufactured as a genuine OEM component, this radiator meets the same material and construction standards as the unit installed at the factory.
The radiator is the heart of the engine cooling system, circulating coolant through the engine block to absorb heat and then dissipating that heat through the core before returning cooled fluid back to the engine. On a high-demand machine like the FS8400 floor saw — which operates under sustained load during concrete cutting — a fully functional radiator is critical to maintaining safe operating temperatures. When a radiator becomes damaged, corroded, or develops a leak, coolant loss and overheating can follow quickly, risking costly engine damage and unplanned downtime on the cut.
