Thermostat tube hose Bottom coolant wate hose for Land Rover Thermostat hose OE LR042893

Product Description:

Thermostat Water Pipe

OE NO.: LR042893

Applicable vehicle type: For Land Rover

The thermostat hose is a vital component within the automotive cooling system, connecting the thermostat to other parts. It directs coolant into the thermostat to regulate the engine's operating temperature. During cold engine starts, the thermostat remains closed, directing coolant through the thermostat hose for a small-loop circulation that rapidly raises engine temperature. Once the engine reaches operating temperature, the thermostat opens, allowing coolant to enter the main circulation loop via the thermostat hose. This coolant then flows through the radiator for heat dissipation, ensuring the engine maintains an optimal operating temperature and preventing overheating or excessive cooling.

• Rapid warm-up: During cold starts, the thermostat remains closed, confining coolant to the internal engine circuit for swift temperature elevation.
• Circuit path switching: Upon reaching the set temperature (typically 82–95°C), the thermostat opens, directing coolant through the thermostat hose to the radiator for full-system circulation.
• Preventing Overheating/Overcooling: A deteriorated or ruptured thermostat hose causes coolant leakage or circulation disruption, leading to engine overheating (‘boiling over’) or increased fuel consumption.

Replacement Interval: Inspection recommended every 60,000 km, replacement at 100,000 km; replace immediately upon detecting leaks or swelling.

Installation Key Points:

- Operate with engine cold; drain coolant;

- Use elbow clamp pliers to ensure clamp is fully seated;

- After refilling, bleed air via the bleed screw to prevent air locks causing false high temperatures.
