Overview
This is an OE-specification replacement thermostat and housing assembly engineered for Land Rover Freelander LR2, Range Rover Evoque, Discovery Sport, and Jaguar XF diesel models equipped with 2.2L single-turbo diesel engines. Engine temperature management is fundamental to fuel efficiency, emissions control, and longevity—a failing thermostat can trigger check-engine lights, poor idle quality, and radiator strain.
Built to original equipment specifications and manufactured to ISO quality standards, this assembly opens at 83°C (182°F)—the optimal threshold for your diesel powerplant's thermal management. The polypropylene housing resists corrosion and coolant degradation, and the precise bimetallic thermostat element maintains consistent flow without hysteresis or drift.
Fits as a direct replacement for part numbers LR001312, C2S44028, 9657182080, and 1427919. Installation is straightforward—typically 30–45 minutes with basic hand tools and no special diagnostic equipment required.

Installation Notes
Difficulty: Intermediate | Time: 30–45 Minutes
-
Cool the engine: Allow the vehicle to sit for at least 30 minutes after shutdown. Coolant system pressure can reach 20+ psi when warm—high-temperature scalding risk.
-
Remove coolant hose(s): Locate the thermostat housing on the engine block near the water pump or upper radiator hose junction. Disconnect hoses or unbolt the housing cap, depending on model year.
-
Drain excess coolant: A small amount will escape; position a drain pan underneath to avoid spillage on engine bay components.
-
Remove old thermostat: Carefully lift out the old thermostat element and discard. Clean the housing bore of any debris, mineral buildup, or old gasket material using a soft brass brush or cloth.
-
Install new thermostat: Insert the new thermostat element with the spring side facing the engine block. The element should sit flush in the bore without forcing.
-
Reinstall housing: Position the housing cover or hose fitting and secure with the original bolts. Torque to 20–25 Nm (15–18 ft-lbs); do not over-tighten, as polypropylene can crack under excessive load.
-
Reconnect hoses: Reattach coolant hoses and tighten hose clamps to firm hand-tight plus 1/4 turn.
-
Refill coolant: Top up the expansion tank with coolant matching your vehicle's spec (typically Jaguar coolant or equivalent blue G12+ fluid for these engines). Fill to the "max" line with the engine cold.
-
Bleed air: Start the engine and allow it to idle for 2–3 minutes. You may hear burbling as air is expelled. Do not rev the engine immediately.
-
Monitor temperature gauge: Confirm the needle rises smoothly and stabilizes at mid-scale (around 90°C). The fan should cycle on briefly once the engine reaches operating temperature.
-
Check for leaks: After 5 minutes of idle, inspect the thermostat housing and hose connections for seepage. If a slow drip is present, stop the engine, allow cooling, and gently snug the clamp or bolt—do not force.
-
Test drive: Take a short drive and confirm the gauge remains stable; check for any coolant odor or steam. Let the engine cool completely before stopping to verify no thermal stress has occurred.
Important: Always dispose of old coolant responsibly—never pour into drains or soil. Ethylene glycol is toxic to aquatic life. Use a recycling facility or bring it to your local hazardous waste depot. Also, if your vehicle has been sitting unused, the cooling system may have corrosion or sediment; consider flushing the entire system before installation for optimal performance.
Why Choose This Thermostat?
Engine thermostats fail silently—cold engines consume more fuel, emit excess hydrocarbons, and strain the radiator. Hot engines overheat without warning, risking head gasket failure and catastrophic engine damage. This assembly restores precise thermal management, ensures stable idle quality, and maintains your diesel engine's efficiency and lifespan. With a 12-month warranty and OE-matched performance, it's the definitive fix for overheating or cold-running diesel Land Rovers and Jaguars.
