Overview
The water outlet tube—also called the thermostat bypass hose—is a critical component in Land Rover's cooling circuit. It channels coolant directly from the thermostat housing to the water pump, maintaining optimal engine temperature during cold start and under load. For Discovery 4, Range Rover Sport (2010–2013), Range Rover (2010–2012), and the modern Velar platform, this hose endures thermal cycling, pressure spikes, and age-related degradation.
Our Partsmost OEM-quality replacement matches the original equipment specifications exactly. Designed for both 3.0L TDV6 and 5.0L V8 petrol engines, it restores coolant flow integrity without compromise. Installation is straightforward—no special tools required—and the part arrives complete, ready to fit.
If your engine is running hot, you're seeing coolant trace or weeping at the thermostat housing, or your vehicle throws a temperature warning, this hose is the first point to inspect. A failed outlet tube can lead to localized overheating and sensor faults. Replace it before it creates secondary damage.

Installation Notes
DIY Difficulty: Intermediate | Time: 45–60 minutes
-
Cool the engine. Allow at least 30 minutes after shutdown. The cooling system is under pressure when hot.
-
Locate the thermostat housing. On V6 and V8 engines, it sits on the front-right or front-center of the engine block, near the top.
-
Relieve coolant pressure. Use a coolant catch container. Some systems have a bleed screw on the housing; open it first.
-
Disconnect hose clamps. Use a screwdriver or hose clamp pliers. Mark clamp positions if reusing; note hose orientation.
-
Remove the old hose. Gently twist and pull to break any adhesion. Some coolant will spill; place the catch container underneath.
-
Clean the fittings. Wipe the thermostat outlet and water pump inlet with a lint-free cloth. Check O-rings; replace if hardened.
-
Install the new hose. Slide it over both fittings firmly. It should sit flush with no gaps. Reposition clamps to their original locations and tighten snugly—not over-tight.
-
Top up the coolant. Use Land Rover-spec coolant (usually pink or green, depending on your model). Fill to the cold-line on the overflow tank.
-
Bleed air. Run the engine at idle for 5 minutes with the expansion tank cap loose. You may see air bubbles; this is normal. Add coolant as needed.
-
Test. Check for leaks at both ends of the hose. The engine should reach normal operating temperature (around 90°C on the dash gauge) within 10 minutes.
⚠️ Warning: Never open the coolant system while the engine is hot. Pressurized coolant can cause severe burns. Allow minimum 30 minutes cool-down. If you lack confidence, have a Land Rover specialist perform the swap.
