This Genuine Engine Block Plug is designed for Nissan Patrol GU Y61 models fitted with the ZD30 engine when converting from a factory water-cooled turbo system to a later-style oil-only turbo setup. It seals off the factory coolant feed port in the engine block, ensuring the cooling system remains properly pressurised and leak-free after the turbo conversion.

When upgrading or replacing the original turbocharger, the factory water cooling circuit is no longer required. Without this plug, the open coolant passage would result in coolant loss and potential engine damage. This OEM Nissan component provides a clean, reliable, factory-style solution for blocking the port correctly.

Manufactured to Nissan specifications, this plug ensures perfect fitment, long-term sealing performance, and durability under high engine temperatures and pressure conditions.
