Rad Hose Lower 21501-FJ100

🛠️ Description & Function

This is a lower radiator hose—a thick, molded rubber hose that connects the bottom outlet of the radiator to the engine’s water pump. It plays a key role in returning coolant to the engine after it’s cooled, maintaining the proper temperature under heavy load. Designed to resist high heat, pressure, vibration, and contact with oils/industrial fluids.

🔧 Compatibility

✅ OEM-style part often used on Toyota and Nissan industrial vehicles (forklifts, etc.).
✅ Likely replaces Toyota lower hose applications with part number prefix 21501 and suffix ‑FJ100.
✅ Cross-usage with similar numbers like 21503‑FJ100 on some brands—check exact fit.
