Applicable vehicle type: For Land Rover

Automotive coolant hoses are core connecting and conveying components of the engine cooling system, typically made of rubber or plastic. As a flexible pipe network, they connect key components such as the engine, radiator, water pump, and heater core, forming a closed circulation loop specifically for conveying engine coolant.

Repair and Replacement Methods

1. Repair Principles:

• Replacement of Assemblies: Once coolant hoses are damaged, they must be replaced as a whole and cannot be repaired. This is the only safe and reliable repair method.
• Preventive Replacement: It is recommended to perform preventive inspection and replacement of critical hoses (such as upper and lower radiator hoses) when the vehicle has been driven 80,000 to 100,000 kilometers or 5 to 6 years, even if no obvious cracks are visible.

2. Professional Replacement Steps:

• Safety First: Ensure the engine is completely cooled before operation to prevent scalding.
• Pressure Release and Drainage: Open the cooling system pressure cap and drain part of the coolant (which can be collected in a clean container).
• Removal of Old Hose: Loosen the clamps at both ends, carefully twist and pull out the old hose.
• Cleaning of Interfaces: Clean the metal interfaces on the engine and radiator to ensure there are no residual dirt or rust.
• Installation of New Hose: Install the new hose in place, ensuring sufficient insertion depth.
• Replacement of Clamps: New stainless steel clamps must be used, and they must be tightened to the specified position.
• Refilling and Bleeding: Re-add coolant to the specified level, start the engine and run it until the fan starts to perform system bleeding, and finally check the liquid level and for any leaks again.
