Performance Water Pump & Thermostat Kit for Land Rover Range Rover Sport (2014-2020) 3.0L

Heavy-Duty Aluminum Water Pump & Thermostat Kit for 2014-2020 Land Rover Range Rover Sport (L494)

What it Does: The Performance Water Pump & Thermostat Kit replaces failure-prone factory cooling components on the 2014-2020 Land Rover Range Rover Sport to eliminate catastrophic coolant loss and regulate engine operating temperatures under sustained thermal load.

The Stock Land Rover Range Rover Sport Brittle Plastic Failure

The factory cooling circuit on the L494 Range Rover Sport relies extensively on composite plastic coolant pipes, a weak factory thermostat housing, and a failure-prone mechanical water pump. Under the intense thermal cycles generated by the supercharged AJ126 3.0L V6 and AJ133 5.0L V8, these molded seam lines become brittle, micro-fracture, and fail suddenly. The notorious front and rear plastic crossover pipes are prone to splitting without warning, causing rapid coolant evacuation, severe heat soak, and catastrophic engine overheating that warps cylinder heads and blows head gaskets.

The Engineering Solution

This upgraded service kit resolves inherent OEM weaknesses by replacing fragile molded plastic coolant crossover tubes with high-grade, corrosion-resistant cast aluminum pipes. Featuring an upgraded high-flow mechanical water pump, a pre-assembled thermostat housing with an integrated temperature sensor, and durable copper bleeder fittings, this system eliminates typical seam-rupture failure points. The aluminum infrastructure maintains dimensional stability through hundreds of thermal heat cycles, ensuring leak-free performance and consistent cooling pressure throughout the engine block.

What's Included

• 1 Thermostat with a Sensor

Frequently Asked Questions & Fitment Warnings

Does this fit the L494 Range Rover Sport?

Yes, this is a direct fit for the 2014-2020 Land Rover Range Rover Sport equipped with the AJ126 3.0L supercharged engine; it does not fit naturally aspirated engines.

Do I need to vacuum bleed the cooling system after installing this kit?

Yes, proper evacuation and vacuum bleeding are critical on supercharged Jaguar Land Rover engines to prevent trapped air pockets that trigger localized overheating.
