Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Coolant Expansion Tank Cap rated at 1.4 bar, fitted to the expansion (header) tank of the engine cooling system.

The cap seals the expansion tank and regulates system pressure. It holds the coolant under pressure to raise its boiling point, while a relief valve vents excess pressure once it exceeds the 1.4 bar rating, protecting the tank and hoses. An integral vacuum valve draws coolant back from the overflow as the system cools and contracts.

Frequently asked questions

What is the PCD000070LR expansion tank cap?
The PCD000070LR is a genuine Land Rover 1.4 bar coolant expansion tank cap for the Discovery 2, Range Rover P38 and Range Rover L322. It seals the header tank and keeps the coolant pressurised to raise its boiling point.
What does the 1.4 bar pressure rating do?
The 1.4 bar rating sets the pressure at which the cap vents through its relief valve, protecting the tank and hoses, while its vacuum valve draws coolant back as the engine cools. A cap that can't hold 1.4 bar lets the system run hot.
Which Land Rovers take the PCD000070LR cap?
It fits the Discovery 2 (Td5 and V8), Range Rover P38 and Range Rover L322 (4.4 V8 petrol and 3.0 diesel). This is the genuine Land Rover version, so it matches the original cap fitted to the header tank on those models.
When should the cap be replaced?
Replace the cap when the seal hardens or the pressure valve weakens, as it then loses system pressure and the engine can overheat or boil over. A failed 1.4 bar cap is a common and cheap cause of coolant loss to rule out first.
