Land Rover Genuine Core Plug 602146

Description

The Land Rover Genuine Core Plug 602146 is a critical component designed to seal the core holes in your vehicle’s engine block or cylinder head. Also known as a freeze plug or expansion plug, this part ensures that coolant remains securely contained within the engine’s internal passages, preventing leaks and maintaining proper operating temperatures. Manufactured to Land Rover’s official OE specifications, this genuine part guarantees a flawless fit and factory-standard performance for compatible Land Rover models.

Crafted from high-strength, corrosion-resistant materials, the 602146 core plug is engineered to endure the extreme pressure and temperature cycles experienced by engine cooling systems. Its precise dimensions and finish make it an ideal replacement for aging or corroded core plugs, offering peace of mind for Land Rover owners who value original parts and long-lasting engine reliability.

Working

The Land Rover Genuine Core Plug 602146 operates by sealing the access holes left in engine blocks and cylinder heads during the manufacturing process. These holes are necessary for removing casting sand and machining the internal engine components. Once assembly is complete, they must be closed with precision plugs to contain the engine coolant.

Installed flush within the engine’s cooling jacket, this core plug prevents coolant leaks that could lead to engine overheating and severe mechanical damage. Its ability to expand slightly under heat ensures a tight, leak-proof seal, even as temperatures fluctuate. Over time, older core plugs may deteriorate due to rust or coolant corrosion — replacing them with this genuine part restores the original safety and reliability of your Land Rover’s cooling system.

Engineered to meet Land Rover’s rigorous quality standards, the Genuine Core Plug 602146 is built from durable, corrosion-resistant metal designed to withstand years of heat, pressure, and exposure to coolant chemicals. Its OE-grade manufacturing ensures a precise fit, maintaining proper engine operation and preventing coolant system failures. Trusted by professional technicians and 4×4 enthusiasts alike, this core plug is a vital maintenance item for anyone committed to preserving the long-term performance of their Land Rover vehicle.
