Nissan Qashqai Renault Megane III 1.5 dCi Gas Exhaust Manifold 140042062R

Nissan Qashqai Renault Megane III 1.5 dCi Gas Exhaust Manifold is an original component from the Exhaust manifolds group, designed for diesel engines. Engineered specifically for 1.5 dCi units, it ensures proper exhaust gas discharge, stable turbocharger operating conditions, and predictable powertrain performance. This is a solution for users seeking a proven, factory-made component rather than universal replacements.

Purpose and compatibility with Diesel engines

The presented exhaust manifold has been developed for 1.5 dCi diesel engines. The geometry of the channels, cross-sections, and mounting points are adapted to the specifics of the diesel engine, which allows for maintaining correct exhaust pressure, appropriate operating temperature, and stable conditions for the turbocharger and exhaust gas recirculation system.

Thanks to its factory origin from the Renault group, the manifold works with the equipment used in Nissan Qashqai and Renault Megane III models, minimizing the risk of fitment issues, leaks, or incorrect alignment of the exhaust system relative to the engine block and accessories.

Technical and functional characteristics

The exhaust manifold is responsible for collecting exhaust gases from individual cylinders and directing them to the rest of the system, which is why its design has a direct impact on flow dynamics, thermal load, and the acoustics of the engine. This model uses solutions typical for dCi engines, ensuring:

• stable exhaust discharge under loads characteristic of diesel engines,
• proper alignment of ports and mating surfaces relative to the cylinder head,
• compatibility with the factory turbocharging system and the subsequent section of the exhaust,
• the ability to retain stock heat shields and mounts.

A component configured in this way helps maintain the correct operating characteristics of the exhaust system, which translates into engine refinement, noise levels, and conditions for the exhaust gas treatment system.

Used condition and benefits of choosing OEM parts

The offered exhaust manifold is a used item, which allows for combining reasonable purchase costs with the preservation of factory geometry and build quality. Unlike many replacements, the OEM part retains original mounting points, channel shapes, and fitment to accessories, which facilitates installation and reduces the risk of additional modifications.

For workshops and individual users, this means:

• easier planning of service work thanks to predictable fitment,
• lower risk of leaks at the interface with the cylinder head and the rest of the system,
• maintaining the stock operating parameters of the 1.5 dCi unit without experimenting with universal solutions.

Application in service practice

Replacing the exhaust manifold in a 1.5 dCi engine is often part of a wider scope of work – e.g., during turbocharger maintenance, fixing exhaust leaks, or upgrading the exhaust system. Using an original Renault exhaust manifold allows for restoring factory exhaust flow conditions and limiting the risk of secondary failures resulting from improper component fitment.

If you are planning a comprehensive repair or upgrade of the engine area in your Renault and need other elements from the same group, such as manifolds, connection sections, or mounting elements, check the available parts in the Renault exhaust manifolds category.
