FAQs

Does this tank come with the cap?

Is the sensor included?

Yes, the coolant level sensor is pre-installed in this unit.

What OEM part numbers does this replace?

Will this fit my Range Rover Sport?

Do I need special tools to install this?

Standard hand tools such as screwdrivers and pliers for hose clamps are generally sufficient for the installation.

Why is it important to replace the expansion tank?

Over time, plastic tanks become brittle and develop cracks, leading to coolant leaks and a loss of system pressure which can cause engine overheating.

Troubleshooting

Coolant warning light remains on after installation

Ensure the sensor plug is fully seated and the electrical pins are clean and free of corrosion.

System not holding pressure

Verify the cap is tightened correctly and check that all hose connections are fully seated with functional clamps.

Setup Instructions

Ensure the engine is completely cool before attempting any work on the cooling system.
Place a drain pan under the vehicle to catch leaking coolant.
Disconnect the sensor electrical plug.
Remove the old reservoir by unscrewing the mounting fasteners.
Carefully transfer existing hoses to the new NRF tank.
Mount the new tank, reconnect the sensor, and fill with the manufacturer-recommended coolant.
