Overview
If you're running a Discovery 4, Range Rover (2010–2023), Range Rover Sport, Range Rover Velar, or Defender with a 3.0L V6 or 5.0L V8 petrol engine, your thermostat and housing work overtime. They regulate coolant flow to keep engine temperature in the sweet spot—critical for reliability, efficiency, and longevity.
This OEM-specification thermostat housing assembly is engineered to match Land Rover and Range Rover factory standards. It's built from durable polypropylene (PP) with precision-machined sealing surfaces, ensuring zero coolant weep and consistent thermal control across all driving conditions.
Whether you're replacing a worn original or upgrading preventatively, this unit delivers the same performance you'd expect from a Land Rover dealer part—at a fraction of the cost.

Installation Notes
DIY or Professional?
Difficulty: Intermediate | Time: 1–2 hours | Coolant top-up required
-
Drain coolant from radiator petcock or lower hose. Catch in a drain pan. (Dispose of responsibly; antifreeze is recyclable.)
-
Remove upper radiator hose and coolant expansion tank if necessary to access thermostat housing.
-
Unbolt old housing (3–4 bolts, typically 10mm or 13mm). Lift clear and set aside.
-
Clean mating surfaces thoroughly with a rag and gasket scraper. No old sealant residue should remain.
-
Position new thermostat housing with integrated thermostat facing the engine block. Align bolt holes.
-
Install and torque bolts to Land Rover spec (~20–25 Nm). Do not over-tighten; cracking risk on plastic housing.
-
Reconnect hoses and tighten clips securely. Double-check all connections.
-
Refill coolant with a 50/50 antifreeze/distilled water mix (or OEM-approved equivalent). Bleed air from the system by running the engine on idle with the expansion tank cap off until coolant flow stabilises.
-
Top up expansion tank to the correct level once the engine cools.
-
Check for leaks around the new housing seams and hose connections. Run the engine to operating temperature and inspect again.
⚠ Important: Allow the engine to cool fully before beginning work. Pressurised coolant and hot metal surfaces cause severe burns. If you're unsure about any step, consult a Land Rover specialist or take the vehicle to a professional technician.
Why This Thermostat Matters
A worn or failed thermostat housing can cause overheating, coolant leaks, and sensor faults that trigger check-engine lights. Preventative replacement is much cheaper than dealing with engine damage. This OEM-spec assembly ensures your cooling system stays in peak condition and your engine runs reliably for years to come.

Keep your cooling system in top shape. This thermostat housing is engineered to Land Rover standards and ships worldwide within 48 hours.
