Genuine Nissan Exhaust Manifold Gasket YD25 - Nissan Navara D22, D40 & Pathfinder R51

This is a Genuine Nissan exhaust manifold gasket designed to suit Nissan Navara D22, D40, and Pathfinder R51 models equipped with the YD25 common rail diesel engine. The gasket fits between the exhaust manifold and the cylinder head, creating a critical seal to prevent high-pressure exhaust gases from leaking. It is manufactured from Multi-Layer Steel (MLS) to withstand the extreme heat and vibration generated by the turbocharged engine.

Over time, the original gasket can degrade from constant heat cycles, leading to failure. Symptoms of a failed gasket often include a distinct high-pitched squeal or ticking noise from the engine bay, noticeable loss of engine performance, and an increase in fuel consumption. Replacing a failed gasket with a Genuine Nissan part is essential to restore performance and prevent potential damage to surrounding components from hot exhaust gases.

Product Features

• Genuine Nissan Part: Manufactured to Nissan's exact OEM specifications for a perfect fit, reliable performance, and maximum service life.
• Multi-Layer Steel (MLS) Construction: Engineered to endure the extreme temperatures and pressures of a turbocharged diesel system, providing a superior, long-lasting seal.
• Direct-Fit Replacement: Designed as a direct replacement for the original gasket, ensuring a straightforward installation with no modifications required.
• Restores Performance: Creates a reliable seal that eliminates exhaust leaks, silencing unwanted engine noise and restoring lost power and fuel efficiency.

Installation Notes

Installation of this gasket is considered a moderate to difficult workshop job. Access to the manifold can be challenging, and the original manifold studs and nuts are often seized from heat cycling, which may require specialised tools for safe removal. It is strongly recommended to replace the exhaust manifold studs and nuts at the same time to ensure a proper, leak-free seal on reassembly.
