Radiator outlet water pump pipe Cooler tube hose OE LR033994 Radiator outlet hose for Land Rover

Product Description:

Radiator Water Overflow Hose

OE NO.: LR033994

Applicable vehicle type: For Land Rover

The Radiator Water Outlet Hose is a critical component within the engine cooling system, connecting the radiator outlet to the engine or water pump inlet. It is responsible for returning cooled coolant to the engine, thereby maintaining stable system circulation.

Maintenance Recommendations:
1. Replace radiator hoses at specified intervals

• Even without visible defects, hoses should be replaced periodically as per the vehicle manual (typically every 40,000–60,000 kilometres or 3–5 years). Vehicles operating in high-temperature, humid, or dusty environments require shorter replacement cycles.
• Prioritise genuine OEM or premium-brand hoses (e.g., EPDM rubber with reinforcement layers), avoiding substandard hoses to minimise premature ageing risks.

2. Regular coolant replacement + system flush

• Coolant degrades over time, producing corrosive substances that accelerate inner hose corrosion. Replace coolant every 2-3 years or 40,000-60,000 kilometres, ensuring complete drainage of old fluid to prevent effectiveness loss from mixing.
• If significant impurities exist in the cooling system, employ specialised coolant flush agents to remove scale and rust from hoses and radiators, reducing blockage and corrosion risks.

3. Prevent contact between hoses and high-temperature components

• During engine operation, components such as the exhaust manifold and turbocharger reach extremely high temperatures. If hoses come into contact with or are positioned too close to these components, it will accelerate hose deterioration.
• Should inspection reveal interference between hoses and high-temperature components, install heat shields or re-route the hoses to avoid direct exposure to intense heat.

4. Avoid excessive bending or stretching during installation

• When replacing hoses, adhere to the original factory layout. Prevent excessive bending, twisting, or stretching to avoid long-term stress causing seal failure at connections or wall cracking.
• When securing hoses, ensure clamps are correctly positioned with moderate tension (over-tightening may damage hose interfaces, while insufficient tightening compromises sealing).
