Womala Warm Air Pipes OE LR122710 for Land Rover Range Rover

Product Overview

The Water Outlet Connector LR122710 is an OE-grade cooling system component engineered for 3.0L V6 supercharged petrol engines (AJ126) in select for Land Rover and for Jaguar vehicles. Also known as a rear heater manifold pipe, water manifold for heater, or coolant outlet flange, this component routes coolant from the engine block to the heater core and regulates coolant flow through the rear cooling circuit.LR122710 is the current replacement part, superseding LR109401, LR087558, LR075991, LR041788, C2Z18624, and AJ813848.

⚠️ Important: This connector is specifically for the 3.0L V6 supercharged petrol engine (AJ126) — it is not compatible with diesel or 5.0L V8 variants. An upgraded aluminium version is available, replacing the failure-prone factory plastic design for enhanced durability.

Key Features

• Critical cooling junction – connects the engine block to the heater core, routing coolant through the rear cooling circuit

• Upgraded aluminium option available – replaces factory plastic with reinforced metal construction for superior durability and heat resistance

• Complete assembly – includes integrated temperature sensor and O-ring seals

• OE-grade quality – available as Genuine Land Rover, Wahler, URO Parts, Dorman, and Britpart alternatives

OE Cross-Reference

💡 Supersession Note: LR122710 is the current replacement part. All listed numbers refer to the same water outlet connector for 3.0L V6 supercharged petrol applications.

Technical Specifications

Vehicle Fitment

⚠️ Important: This water outlet connector is confirmed for the 3.0L V6 supercharged petrol engine (AJ126) in the models listed above. Confirm your engine type and VIN before ordering.

Signs of Failure

• Coolant leaks – visible drips from the connector or heater pipe area

• Low coolant warning – recurring need to top up the reservoir

• Engine overheating – coolant loss compromising temperature regulation

• Loss of cabin heat – heater blows cold air

• Sweet coolant smell – from the engine bay

• Visible cracks or brittleness – plastic connector degradation from heat cycling

💡 Known Failure Issue: The factory plastic water outlet connector on the AJ126 engine is a documented high-failure component. The sonic-welded plastic seams crack under thermal cycling, causing sudden coolant loss. If not addressed promptly, coolant loss can cause catastrophic engine damage including warped cylinder heads and blown head gaskets. Upgraded aluminium versions are strongly recommended for enhanced durability and to prevent repeat failure.

Critical – Verify Your VIN Before Ordering

Water outlet connectors are VIN-, engine-, and model-year-specific. 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. The connector is located at the rear of the engine, and access may require removal of the supercharger on some applications. When replacing, inspect all cooling system hoses and connections for wear. It is recommended to replace the thermostat and water pump at the same time for a complete cooling system service. Refill with OEM-specified coolant at the correct mixture ratio and bleed the cooling system thoroughly to remove air pockets. Consider upgrading to the aluminium version for enhanced durability and to prevent repeat failure.
