Parts for your 2013 Nissan Pathfinder-Manifold gasket

2013 Nissan Pathfinder manifold gasket — purpose and service tips

Based on Nissan technical sources, a manifold gasket is definitely used on the 2013 Nissan Pathfinder (R52). The Factory Service Manual for the R52 Pathfinder (Engine Mechanical and Exhaust sections) specifies intake manifold gaskets and exhaust manifold gaskets for the VQ35DE 3.5‑litre V6, and the Nissan parts catalogue lists genuine replacement gaskets for both locations. So, the manifold-gasket is relevant to this model and is a normal wear-and-seal component whenever the intake or exhaust manifolds are removed or when leaks are diagnosed.

On this Pathfinder, the intake manifold gasket seals the junction between the intake manifold and the cylinder heads, keeping unmetered air out so the engine management can control fuel trims properly. A tight seal helps cold starts, smooth idle, decent fuel economy and keeps the check-engine light at bay. The exhaust manifold gasket, on the other hand, keeps hot exhaust gases from escaping before they reach the catalytic converters and oxygen sensors. That protects nearby components, reduces noise, avoids exhaust odours under the bonnet or in the cabin, and keeps O2 readings accurate for correct fueling.

There’s no fixed kilometre-based replacement interval for these gaskets
