Overview
The heater manifold tube is a critical coolant pathway in your Land Rover Discovery LR4 or Range Rover. Over time, plastic components degrade under thermal cycling, leading to weeping seals, coolant leaks, and potential overheating. This OEM-specification replacement restores full cooling system integrity without modification.
This genuine-specification heater manifold tube is engineered for the 3.0L AJ126 supercharged V6 petrol engines found across Land Rover and Jaguar platforms. It includes the integral temperature sensor that feeds real-time coolant data to your engine control unit—essential for proper fuel metering and fan management.
Every unit is pressure-tested and quality-verified before dispatch. Installation requires no special tools, and your vehicle's diagnostic systems will recognize it immediately. Backed by our 30-day money-back guarantee and 12-month warranty.

Installation & Difficulty
DIY Installation – Intermediate (2–3 hours)
- Allow engine to cool for minimum 30 minutes after running. Do not open cooling system while hot.
- Locate heater manifold tube on driver's side of engine bay, behind intake manifold.
- Disconnect wiring harness from integrated sensor (single connector).
- Remove hose clamps securing coolant inlet and outlet lines.
- Carefully withdraw old tube and sensor assembly.
- Install new heater manifold tube with sensor, ensuring all clamps are tight and sensor connector is fully seated.
- Refill cooling system with OEM-spec coolant (typically 50/50 antifreeze) to marked level.
- Run engine for 5 minutes to purge air pockets and verify no leaks.
- Check coolant level again after cooling cycle.
- Clear any diagnostic codes using OBD2 scanner if required (typically clears automatically).
⚠ Warning: Coolant system is pressurised. Do not work on this component while engine is hot. Use only OEM-equivalent coolant—mixing brands can compromise protection. If you see steam, odour, or active leaking, stop work and consult a specialist.
