Frequently asked questions

What does the cylinder block core plug seal do?
The cylinder block core plug seal seals a casting core plug aperture in the cylinder block, preventing coolant leaking from the water jacket. It's used across several Land Rover petrol engines, including AJ133 5.0 V8 and 3.0 SC V6 applications.
Where is the core plug seal located?
The core plug seal sits at a core plug opening in the cylinder block, sealing the coolant water jacket. It fits a wide range of models including the Defender, Discovery 3 to 5, Range Rover L322 and L405, Range Rover Sport and Velar petrol engines.
Why does a core plug seal need replacing?
A core plug seal is renewed when it perishes and lets coolant seep from the block water jacket. Given the broad engine range this seal covers, use your VIN and engine to confirm the correct part before ordering.
