Radiator coolant hose for Land Rover Bottom radiator hose OE LR006993 Radiator hose pipe

Product Description:

Radiator water hose

OE NO.: LR006993

Applicable vehicle type: For Land Rover

The primary function of the radiator lower coolant hose is to serve as a conduit within the engine cooling system, responsible for transporting coolant from the radiator to the engine. This enables the coolant to circulate between the engine and radiator, facilitating effective heat dissipation. Consequently, it assists the engine in maintaining its optimum operating temperature, thereby preventing overheating.

Common faults with the radiator lower coolant hose primarily fall into three categories: ageing and cracking, connection failure, and blockage. These issues directly reduce cooling system efficiency and may even cause engine overheating.

Ageing and cracking typically result in:

• Hose cracking / crazing: Prolonged exposure to alternating high temperatures (engine operating temperature) and low temperatures (ambient temperature) causes the rubber material to gradually lose elasticity, developing fine surface cracks. In severe cases, this leads to direct rupture and coolant leakage.
• Hose bulging / expansion: Internal coolant pressure acts upon the hose. If material strength diminishes or localised weak points exist, pressure can cause bulging. Continued use may result in sudden rupture.
• Hardening / Brittleness: Aged rubber loses its inherent flexibility, becoming rigid and brittle. This impairs its ability to accommodate engine vibration and component movement, making it prone to fracture at joints or bends.
• Outer Layer Wear: Friction from other engine compartment components (such as belts or pipes) or abrasion from foreign objects (like mud, sand, or stones) can damage the hose's outer layer, accelerating internal deterioration.
