Maintain a secure, leak-free exhaust manifold seal with this Genuine Nissan Exhaust Manifold Washer, designed specifically for Nissan Patrol GQ Y60 and GU Y61 models fitted with TB42, TB45, and TB48 petrol engines. This OEM washer is used between the exhaust manifold and cylinder head, helping maintain correct clamping force and sealing integrity under extreme exhaust heat and vibration.

Over time, exhaust manifold washers can become flattened, corroded, or heat fatigued due to constant thermal cycling. When reused or worn, they can no longer provide proper load distribution, leading to exhaust leaks, ticking noises on cold start, reduced performance, and increased fuel consumption. Left unresolved, manifold leaks can also contribute to gasket failure and further damage to surrounding components.

Manufactured to genuine Nissan specifications, this direct-fit replacement washer ensures correct sealing performance and helps maintain long-term reliability of your Patrol’s exhaust system.
