Land Rover Part Number: PCD000070 - Expansion Tank Pressure Cap
PCD000070 is an Expansion Tank Pressure Cap. It seals the radiator/coolant overflow container and controls pressure within the engine cooling system for the specified engines. As the coolant warms and pressure rises it permits excess fluid to flow to the overflow and, as the system cools, allows coolant to be drawn back into the circuit. The cap also helps prevent air entering the cooling system and supports heat-transfer performance by allowing the system to operate at a higher boiling point. Common fitments for this cap include Discovery 2 and Range Rover P38 and L322 applications specified for 2.5D, Td6 and 4.4 V8 engines.
