Product Overview
The Heater Manifold Pipe LR109402 is a genuine OE-grade cooling system component engineered for 5.0L V8 petrol engines (AJ133) in select for Land Rover and for Jaguar vehicles. Also known as a rear coolant water heater pipe or coolant outlet flange, this component routes coolant from the engine block to the heater inlet, playing a critical role in cabin heating and engine temperature regulation. LR122709 is the current replacement part, with a supersession path of LR087559 → LR109402 → LR122709.
⚠️ Important: This pipe is specifically for the 5.0L V8 petrol engine — both naturally aspirated and supercharged variants. It is not compatible with diesel or V6 engines.

Signs of Failure
Coolant leaks – visible drips from the heater pipe area, often onto the transmission bell housing
Low coolant warning – recurring need to top up the reservoir
Loss of cabin heat – heater blows cold air
Engine overheating – coolant loss causing temperature issues
Visible cracks or brittleness – plastic pipe degradation from heat cycling
💡 The factory plastic heater pipe is a known failure point on 5.0L V8 engines — it becomes brittle with age and heat cycling, leading to coolant loss. Upgraded aluminium versions are available as a permanent fix.
Critical – Verify Your VIN Before Ordering
Coolant pipes 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. When replacing the heater pipe, inspect all cooling system hoses and connections for wear. Replace coolant with OEM-specified fluid at the correct mixture ratio after installation. Consider upgrading to the aluminium version for enhanced durability.
