Jaguar Applications

Land Rover Applications (Cross-Reference)

⚠️ Important: This component is specifically for the 3.0L V6 supercharged petrol engine (AJ126) – not for naturally aspirated, diesel, 2.0L, or V8 engines. Some applications may have VIN-specific fitment .

Signs of Failure

• Coolant leaks – visible drips from the heater pipe / manifold area 

• Loss of cabin heat – heater blows cold air

• Engine overheating – coolant loss causing temperature issues

• Sweet coolant smell – from the engine bay

• Low coolant warning – recurring need to top up

💡 This pipe is a common failure point on AJ126 engines . The factory plastic components can become brittle and crack over time – upgraded metal alternatives offer improved durability. If replacing one heater pipe, consider replacing related coolant pipes and the water pump concurrently.

Critical – Verify Your VIN Before Ordering

Coolant pipes are VIN‑, engine‑, and model‑year‑specific. Variations in engine type (3.0L supercharged vs. other variants), production date, and VIN range affect fitment. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. When replacing the heater pipe, the cooling system must be drained and refilled with OEM-specified coolant. Check all sealing surfaces and O-rings during replacement. Upgraded metal pipes are available for enhanced durability .
