Key Features
- Genuine OEM Cooling Spec — Built to the original Kubota D905 & D1105 engine cooling specification, ensuring the correct core size, tank volume, and connection geometry for this application.
- Direct-Fit Replacement — Engineered to match the original mounting points and inlet/outlet positions for a straightforward swap with no fabrication or adaptation.
- Broad AL and RL Series Fitment — Confirmed for the AL4000, AL5000, AL4, AL4L, AL5, AL5L, AL5HT, AL5 with Vertical Mast, RL4, and RL4 Vertical Mast light towers.
- Engine Cooling Integrity — A properly functioning radiator keeps the Kubota engine within its operating temperature range, supporting consistent output and preventing heat-related shutdowns during extended lighting runs.
- Genuine Genie Part — Supplied as a genuine OEM component under Genie part number 866110GT, backed by the quality standards expected for light tower engine service parts.
A radiator transfers heat away from the engine coolant by passing it through a network of tubes and fins where airflow carries the heat away. On Kubota D905 and D1105 powered light towers, the radiator is a critical part of keeping the engine at a stable operating temperature across long overnight or continuous-duty runs. A radiator that is cracked, clogged, or leaking will cause coolant loss, rising engine temperatures, and eventual shutdown — interrupting lighting at the worksite and risking engine damage if left unaddressed. Replacing a failed radiator with the correct OEM part restores proper cooling capacity and protects the engine.
