The Genie 1266745GT is a genuine OEM Upper Radiator Hose for the Kohler KDW1003 engine, built for the RL4 light tower. Sourced directly from Genie, this hose meets the original equipment specification for the cooling circuit it serves. Confirm part number 1266745GT against your RL4 parts manual to ensure it is the correct hose for your unit before ordering.
Key Features
- Genuine OEM Construction — manufactured to Genie's original material and dimensional spec, ensuring the hose seats and seals correctly on the Kohler KDW1003 engine.
- Exact Upper Radiator Position Fit — engineered to the correct length, bore, and end profile for the upper radiator connection, so it drops in without modification.
- Built for the RL4 Light Tower — confirmed fitment for the RL4, keeping the right part matched to the right machine.
- Cooling System Integrity — a sound radiator hose maintains proper coolant flow between the engine and radiator; a cracked or collapsing hose causes overheating and unplanned downtime on the jobsite.
- Safety-Relevant Component — engine overheating due to a failed coolant hose can damage the Kohler KDW1003 and force an unscheduled shutdown; replacing a worn hose promptly keeps the light tower running safely through long-duration tasks.
The upper radiator hose carries coolant from the engine to the radiator, where heat is expelled before the cooled fluid cycles back through the engine. On a light tower like the RL4, the engine runs for extended periods — often overnight — so the cooling circuit must perform without interruption. A hose that is cracked, soft, or leaking at its connections will allow coolant loss, leading to rising engine temperatures and potential engine damage. Replacing a worn hose with the correct OEM part, part number 1266745GT, restores the integrity of the cooling circuit and protects the Kohler KDW1003 from heat-related wear.
