BSNOVT Reservoir Water Hose for Range Rover & Discovery 2013–2020 — OE LR035630/LR146301 Direct-Fit, Pre-Molded Rubber

BSNOVT Reservoir Water Hose is a direct-fit replacement coolant reservoir tube engineered to match OE LR035630 and LR146301 for Range Rover and Discovery models, restoring proper coolant flow and durability.

If your Land Rover’s coolant reservoir connection shows cracks, leaks, or stiffness from age, this pre-molded replacement restores secure coolant routing between the radiator and overflow tank. Designed to align with factory mounts and sealing surfaces, the hose reduces installation time and helps maintain stable engine temperatures by keeping the coolant pathway intact. It’s sized and shaped specifically for Range Rover 2013–2020, Range Rover Sport 2014–2015, 2017–2019, and Discovery 2017–2020 vehicles to ensure a straightforward swap for mechanics and DIYers alike.

Will this hose fit my specific Land Rover model and year?

Yes — the BSNOVT hose is manufactured to replace OE part numbers LR035630 and LR146301 and fits the listed model years without modification. Verify compatibility by comparing your old hose’s routing and part number or consult your vehicle’s service manual for confirmation.

• Compatible models: Range Rover 2013–2020, Range Rover Sport 2014–2015, 2017–2019, Discovery 2017–2020.
• Direct-replacement for OE LR035630 and LR146301.
• Pre-shaped to match factory routing and mounting points.

How durable is this replacement coolant reservoir tube?

The hose is built from premium-grade automotive rubber chosen for flexibility, heat resistance, and chemical tolerance found in engine coolant systems. That durability reduces the chance of swelling, cracking, or softening under repeated heating cycles and exposure to coolant additives.

• High-quality rubber construction for long service life.
• Resists heat, oil, and coolant-related deterioration.
• Pre-molded shape lowers stress at connection points.

How easy is installation — can I fit it myself?

Installation is intended to be plug-and-play: the hose arrives pre-molded and ready to install using the factory clamps and mounting points. Basic hand tools and standard repair knowledge are usually sufficient, but follow vehicle safety procedures and replace clamps if they show corrosion.

• Included: 1 × engine radiator coolant hose, pre-shaped.
• Requires: basic tools and access to the reservoir and radiator connections.
• Tip: Inspect or replace clamps and clean mating surfaces for a reliable seal.

What function does this hose serve in the cooling system?

This tube channels coolant between the radiator or engine and the overflow/reservoir tank, enabling pressure-compensated expansion and recovery of coolant as temperature changes. A secure, leak-free hose helps the cooling system maintain the correct fluid level and avoid overheating scenarios caused by coolant loss.

• Transfers coolant to and from the expansion reservoir.
• Supports proper coolant recovery during thermal cycling.
• Prevents leaks that can lead to low coolant and engine heat issues.

Who is this for: Owners and technicians working on Range Rover or Discovery vehicles within the specified years who need a reliable, OEM-compatible coolant reservoir hose to replace a cracked, hardened, or leaking tube. It’s ideal for those seeking a cost-effective, direct-fit component that reduces installation time and restores normal coolant circulation without routing or fabrication work.
