If you own a Land Rover Discovery LR4, Range Rover (2013+), or Range Rover Sport (2014+), you know that the cooling system is critical to engine longevity.

This is a direct-fit replacement for Partsmost's premium cooling line, engineered to OEM specifications and compatible with the AJ126 3.0L supercharged V6 found across Land Rover and Jaguar platforms. It arrives as a complete assembly with integrated temperature sensor and modern plastic construction designed for reliability and longevity in both city and off-road conditions.

Installation Notes
Difficulty Level: Intermediate | Time: 45–90 minutes
-
Prepare: Allow engine to cool fully. Disconnect the negative battery terminal to prevent electrical shorts during sensor manipulation.
-
Drain (Optional): If coolant spillage concerns you, drain the system into a clean container. Otherwise, cap hoses with shop towels to minimize losses.
-
Remove Old Tube: Unbolt the existing manifold tube from its front-mounted position using a socket set. Disconnect the integrated temperature sensor plug carefully.
-
Transfer Sensor (if required): If your replacement does not include a pre-wired sensor, carefully remove the old one and install into the new tube.
-
Install New Assembly: Position the replacement tube, secure all bolts to OEM torque specification (typically 20–25 Nm), and reconnect the sensor harness with a firm click.
-
Pressure Test: Refill coolant to spec, run the engine for 5 minutes, and monitor for leaks around all connection points.
-
Bleed Air: If your system requires air bleeding, follow your vehicle's service manual protocol or contact our support team.
⚠️ Important: Never work on the cooling system while the engine is hot. Pressurized coolant can cause severe burns. Always allow a minimum of 30 minutes cool-down time before disconnecting hoses.
