Performance Water Pump Kit for Land Rover Range Rover & Sport (2014-2017) 3.0L

Upgraded Aluminum Coolant Water Pump Pipe Kit for 2014-2017 Land Rover Range Rover & Range Rover Sport (L405 / L494)

What it Does: The Performance Water Pump Kit replaces failure-prone factory plastic coolant pipes with robust aluminum construction on the 2014-2017 Land Rover Range Rover and Range Rover Sport to prevent catastrophic coolant loss and engine overheating.

The Stock Land Rover Range Rover Coolant Pipe Vulnerability

The factory cooling assembly on the AJ126 3.0L supercharged V6 relies on bonded plastic crossover pipes and water pump connector necks. Over continuous heat-soak cycles, thermal expansion and engine vibration embrittle the synthetic seam welds. Under normal operating pressures of 15 to 20 PSI, these aging plastic components develop hairline fractures or separate completely without warning, dumping pressurized coolant and risking head gasket failure and warped cylinder heads.

The Engineering Solution

This upgraded cooling overhaul kit swaps brittle thermoplastic tubing for corrosion-resistant cast and mandrel-formed aluminum piping. Complete with a replacement water pump, heavy-duty copper fitting, reinforced rubber coolant hoses, and high-temp fluoroelastomer O-rings, this kit establishes a permanent, leak-free seal. By eliminating vulnerable sonic-welded plastic seams, it withstands elevated cooling pressures and high under-hood ambient temperatures typical of supercharged applications.
