Frequently asked questions

What does the PER000010 coolant reservoir cap do?
The PER000010 coolant reservoir cap seals the expansion tank on the Range Rover L322 cooling system. Its built-in pressure-relief valve holds system pressure, raising the coolant's boiling point and venting only when pressure exceeds the set point. It fits the 4.4 V8 petrol and 3.0 diesel.
Why does a coolant cap need replacing?
A coolant cap fails when its pressure seal hardens or weakens, so the system no longer holds pressure. On the L322, that typically causes coolant loss, overheating, or boiling. A worn cap is a common, low-cost cause of cooling problems worth ruling out first.
Which Range Rover does this cap fit?
This cap fits the Range Rover L322 with the 4.4 V8 petrol (M62 B44) or 3.0 diesel (M57 D30). It seals the coolant overflow reservoir. Confirm your engine before ordering, as cap designs vary across cooling systems.
