Product Description:

Auto coolant overflow hose
OE number: LR091813 T4A1783 T2H1438
Applicable vehicle type: For Land Rover

The automotive coolant reservoir hose is a specialized hose that connects the coolant expansion tank (reservoir) to the main circulation circuit of the engine cooling system (typically the interface of the radiator or overflow pipe). It is usually made of rubber or plastic and is an indispensable component of the engine cooling system circulation loop.

Product Advantages:

• Simple structure and low cost: As a functional component, its design is not complex, and the manufacturing cost is low.
• Key guarantee: Though unobtrusive, it is crucial for maintaining the normal pressure and liquid level of the cooling system, serving as the "unsung hero" in preventing engine overheating.
• Flexible connection: Made of soft material, it can effectively absorb relative motion and vibration between the engine and the body to prevent leakage.

Repair and Replacement Recommendations:

1. Replacement Instead of Repair: Once any of the aforementioned fault symptoms appear in the coolant reservoir hose, it must be replaced as a whole. Rubber components cannot be reliably repaired.

2. Selection Guide:

• Precise Matching: It is essential to select the corresponding parts based on vehicle model, year, and engine type. The length, diameter, and fitting shape of hoses vary greatly among different vehicle models.
• Accompanying Clamp Replacement: When replacing the hose, it is strongly recommended to replace the fixing clamps simultaneously (stainless steel worm clamps are recommended) to ensure reliable sealing.

3. Professional Operation:

• Cold Engine Operation: It must be performed after the engine has cooled down completely to prevent scalding from hot coolant and steam.
• Standard Bleeding: After replacement, the cooling system must be properly bled and refilled to ensure correct liquid level and no air in the system.

Repair and Maintenance Methods:

1. Routine Inspection

• Every 10,000 km or during maintenance, visually inspect: cracks, bulges, and powder marks on the root of the joint and the middle section of the hose.
• Under cold engine conditions, squeeze the hose; it should quickly rebound. If it is hard or brittle, replacement is required.

2. Emergency Handling

• For small cracks: wrap with 3 layers of self-fusing silicone tape and secure with a stainless steel clamp, then drive at low speed to the repair shop.

3. Official Replacement (General Steps)

• Cold engine → Depressurize → Recover coolant.
• Use a flathead screwdriver to loosen the quick-connect lock tab, remove the old hose.
• Compare the new hose length and bends; use accompanying clamps if necessary.
• Moisten the seal ring, insert the connector until it reaches the limit, then press down the lock tab.
• Vacuum fill with coolant → Bleed air → Road test → Recheck coolant level and temperature.
