Parts for your 2015 Nissan Navara-Exhaust gasket

2015 Nissan Navara exhaust gasket — what it is, and when to sort it

Yes, the 2015 Nissan Navara uses exhaust gaskets. Nissan’s factory documentation lists multiple gaskets in the exhaust path, including the exhaust manifold-to-cylinder head gasket, turbo/manifold and turbo/front pipe sealing rings, and front pipe/DPF flange gaskets. See the Nissan Navara D23 (2015) Service Manual: EM – Engine Mechanical and EX – Exhaust System sections, and the Nissan Electronic Parts Catalogue (FAST/EPC) for D23/NP300, which both catalogue these sealing parts. For late-run 2015 D40 variants, the Nissan D40 Service Manual likewise specifies exhaust manifold and pipe gaskets. Major aftermarket catalogues for the Navara (e.g., Walker/Bosal) also list manifold and front pipe gaskets for 2015-on models. So, exhaust gaskets are absolutely relevant and fitted on the 2015 Navara range.

On a 2015 Navara, the exhaust gasket’s job is simple but critical: keep hot gases sealed as they leave the engine and head through the turbo, DPF and piping. A healthy seal stops that tell‑tale ticking on cold start, prevents soot marks at the joints, keeps fumes out from under the ute, and helps the turbo spool and emissions kit (O2 sensors and DPF) do their thing properly.

As part of regular servicing, it’s smart to inspect the exhaust joints for leaks every 40,000–60,000 kilometres or if any new noises or whiffs of exhaust pop up. Common clues of a crook gasket include a chirp or tick that quietens when warm, visible soot around a flange, a diesel smell in the cabin at idle, or a slight drop in boost response on the twin‑turbo 2.3 diesel. If a section of the system is removed (manifold, turbo, front pipe, DPF), plan to replace the associated gaskets as a matter of course — they’re designed to crush once and seal.

When fitting, use the correct style for the joint: multi‑layer steel for the manifold, a fire ring or V‑band style ring at turbo interfaces, and the specified flat or donut gasket at the front pipe. Follow the Nissan torque specs and tightening order from the D23 Service Manual, replace any single‑use fasteners or spring bolts, and support the system so there’s no strain on freshly sealed joints. Check mating surfaces for flatness and clean them without gouging. Avoid generic sealants unless the manual calls for them — most modern Navara gaskets are dry‑fit. After a few heat cycles, a quick recheck for any weeps or fresh soot is worthwhile, especially around the DPF and turbo connections that see the most heat.

• Inspect for leaks every 40,000–60,000 km, or sooner if noise/smell changes
• Always renew disturbed gaskets and follow factory torque procedures
• Use OEM‑equivalent parts suited to high heat and turbo/DPF duty

Popular questions about 2015 Nissan Navara exhaust gaskets

Where are the exhaust gaskets on a 2015 Navara?

They’re found at the exhaust manifold-to-cylinder head, between the turbo and manifold, at the turbo outlet/front pipe (often a V‑band ring), and at front pipe/DPF and other flange joints further down the system. Exact positions and types are shown in the D23 Service Manual’s EX diagrams and the Nissan FAST/EPC listings.

How can someone spot a blown exhaust gasket on a Navara?

Listen for a ticking or puffing noise on cold start that fades as it warms up, look for black soot marks at a flange, and watch for a diesel smell around the engine bay or under the cab. On turbo models, a leak pre‑turbo can soften boost response and slightly bump fuel use.

Should sealant be used with Navara exhaust gaskets?

Generally no. The factory gaskets are designed to seal dry when torqued correctly. Unless a Nissan procedure explicitly calls for a specific compound, stick to clean mating faces, the correct gasket type, fresh hardware where required, and the specified torque/sequence.
