Overview
Land Rover's 5.0L supercharged V8 demands precise coolant flow and temperature control. Over time, the factory heater manifold tube degrades, cracks, or loses its temperature sensor calibration—causing rough idle, reduced cabin heat, and inconsistent cooling. This direct-fit replacement restores the original cooling circuit integrity without modifications.
Engineered as an OEM equivalent, this heater manifold tube carries Partsmost's quality validation and fits Discovery LR4, Range Rover (2010–2020), and Range Rover Sport (2010–2020) models equipped with AJ133 V8 engines. The integrated temperature sensor maintains accurate engine management system feedback, critical for fuel economy and emissions control.
Installation is straightforward for experienced DIY enthusiasts or professional technicians. A 12-month warranty backs every part, and our UK phone support team can advise on fitment before purchase.

Installation Notes
Difficulty: Intermediate | Time: 1.5–2 hours
-
Disconnect the negative battery terminal and allow the engine to cool for at least 30 minutes.
-
Drain the coolant system into a clean container. Refill specification: PAOG2 approved coolant or equivalent.
-
Remove the upper intake manifold cover and disconnect any electrical connectors from the old sensor.
-
Unbolt the old heater manifold tube (typically 3–4 bolts) and disconnect coolant hoses at both ends.
-
Install the new tube in reverse order, ensuring hose clamps are secure but not over-tightened.
-
Connect the temperature sensor plug firmly until it clicks.
-
Refill the cooling system and bleed air pockets by running the engine at idle with the heater on until temperature stabilizes.
-
Check for leaks around all hose connections and sensor interface before returning to normal operation.
⚠️ Important: This job involves hot coolant and engine components. Wear protective gloves and eye protection. If your engine overheats or you encounter weld cracks in the old tube, discontinue use immediately and have the cooling system inspected by a qualified technician. Improper installation can lead to coolant leaks or engine overheating.
