Frequently asked questions

What does the coolant expansion tank cap do on a Land Rover?

The coolant expansion tank cap seals and pressurises the cooling system. A calibrated relief valve inside holds the coolant under pressure, which raises its boiling point and lets the system run hotter without boiling. It also relieves excess pressure and lets the circuit draw coolant back as it cools.

Where is the expansion tank cap fitted?

The expansion tank cap fits on top of the coolant expansion and overflow tank in the engine cooling system. It's the point you check coolant level and top up from, and it sets the operating pressure for the whole cooling circuit.

What are the signs the coolant cap needs replacing?

A worn coolant cap typically shows as coolant loss, overheating, or a system that won't hold pressure. The rubber seal and relief valve inside harden over time, so a cap that no longer seals can cause boil-over even when the rest of the cooling system is healthy.

Which Land Rover models does this cap fit?

This cap fits the New Defender 2020 on, Discovery 4 and Discovery 5, Range Rover L322 and L405, and Range Rover Sport L320 and L494. Check your engine variant against the listing to confirm the correct cooling system application.
