Product Description:

Radiator water hose

OE NO.: LR135308

Applicable vehicle type: For Land Rover

Radiator outlet hose (also known as the lower radiator hose) is a flexible rubber or reinforced nylon tube connecting the lower reservoir chamber of the radiator to the inlet of the engine water pump. It is responsible for returning the cooled, low-temperature coolant from the radiator back to the engine, completing the ‘return leg’ of the cooling system's primary circulation.

Radiator lower water pipe functions

• Circulation Pathway: Ensures the continuous return of cooled coolant to the water pump, maintaining primary circulation flow.
• Vibration Compensation: Accommodates relative engine and radiator movement to prevent rigid pipe rupture.
• Sealing & Pressure Resistance: Withstands 0.2–0.5 MPa pulsating pressure, preventing leaks and air ingress.
• Service Accessibility: Quick-connect or spring-loaded clamp designs enable rapid fluid drainage and replacement at the outlet hose.
