Thermostat housing bypass tube hose OE LR083328 Coolant water hose for Land Rover Thermostat housing tube

Product Description:

Radiator Water Overflow Hose Pipe

OE NO.: LR083328 J9C1664

Applicable vehicle type: For Land Rover

The thermostat housing tube, also known as the thermostat housing pipe, is a vital component of the automotive cooling system.

Primarily serving to connect the thermostat to other components within the engine cooling system—such as the radiator and water pump—it channels the flow of coolant. Working in tandem with the thermostat, it regulates the coolant's circulation path: during cold engine starts, it directs the coolant into a small-loop circuit to rapidly raise engine temperature; once the engine reaches operating temperature, it switches to a large-loop circuit, allowing the coolant to flow through the radiator for heat dissipation. This ensures the engine consistently maintains an optimal operating temperature.

Performance advantage:

• Temperature Resistance: Capable of withstanding the high temperatures within the engine compartment and the rapid fluctuations in coolant temperature. Must not become brittle at low temperatures, nor deform or soften at high temperatures.
• Corrosion Resistance: As coolant contains chemical components such as ethylene glycol and corrosion inhibitors, which possess a degree of corrosiveness, the thermostat housing tube must resist erosion from these substances to ensure long-term operational stability.
• Sealing Performance: Must possess excellent sealing properties to prevent coolant leakage and ensure proper cooling system operation. Typically incorporates high-performance seals or gaskets to enhance sealing effectiveness.
• Strength and Toughness: Possesses sufficient strength and toughness to withstand coolant pressure and vibrations/shocks during vehicle operation, resisting fracture or damage.
