2013 Nissan Serena Exhaust Mounts — What They Do and When to Replace Them

Exhaust mounts (also called exhaust hangers or insulators) are absolutely used on the 2013 Nissan Serena (C26). Nissan’s Electronic Service Manual for the C26 series (EX – Exhaust System) specifies multiple rubber mounting insulators and brackets supporting the front pipe, centre pipe and rear muffler. The Nissan parts catalogue for the C26 likewise lists “Insulator – Exhaust” components for this model, and common aftermarket catalogues include replacement hanger rubbers for the Serena C26. Those technical references make it clear this vehicle relies on exhaust mounts to suspend and isolate the exhaust system.

On the 2013 Serena, the exhaust mounts are small but crucial bits of rubber that suspend the exhaust system from the body. Their job is to keep the pipework and muffler where they should be, while soaking up vibration so the cabin stays quiet and free of droning. The C26’s long wheelbase and people-mover layout put a lot of length in the exhaust, so stable support from these mounts helps prevent metal fatigue, cracking at welds, and contact with heat shields or underbody parts.

Over time, the rubber insulators harden, crack or stretch from heat, road grime and age. When they’re tired, the exhaust can sag or shift, causing knocks over bumps, rattles at idle, or a boom that wasn’t there before. For owners of a 2013 Serena, a sensible service routine is to have the exhaust mounts visually checked at each service interval or at least every 10,000–15,000 km. In coastal Australia and New Zealand, corrosion around brackets can speed up wear, so inspections matter even more.

Replacement is straightforward for a technician: support the exhaust, remove the stretched or cracked insulators, and press on new OE-spec rubbers. A dab of silicone spray helps them slide on without damage. It’s smart practice to renew mounts in sets along a section of pipe rather than just a single perished one, keeping the system evenly supported. While polyurethane options exist, OE-style rubber typically gives the best isolation for family MPVs like the Serena. Any loose or rusted brackets should be repaired at the same time, and fasteners tightened to the workshop manual specs.

If the exhaust looks off-centre in the bumper cut-out, the tailpipe clinks against a heat shield, or there’s a fresh vibration under load, odds are the mounts need attention. Keeping them healthy protects the exhaust, preserves cabin comfort and helps the C26 sail through a Warrant of Fitness or roadworthy check without dramas.

• Typical signs of wear: sagging tailpipe, knocks over bumps, new rattles, visible cracks in the rubber, or misaligned muffler.
• Service tip: inspect every service, replace aged or oil-soaked rubbers and any corroded brackets together.
• Parts guidance: choose OE or OE-equivalent insulators for best noise and vibration control.

Popular questions about 2013 Nissan Serena exhaust mounts

Do all 2013 Serena models have exhaust mounts?
Yes. Every 2013 Nissan Serena (C26) uses multiple rubber exhaust mounting insulators to suspend the pipes and muffler. This layout is documented in Nissan’s C26 Electronic Service Manual and reflected in the Nissan parts catalogue for the model series. Without these mounts, the exhaust would transmit noise and vibration directly into the body and be more prone to damage.

How often should exhaust mounts be replaced on a Serena C26?
There’s no fixed kilometre limit, as life depends on heat, age and local conditions. Many last 5–10 years, but they should be inspected at each service. If the rubber shows cracks, is oil-soaked, or the exhaust is sagging or knocking, replacement is due. In coastal AU/NZ regions, check more often due to corrosion around brackets.

What are the symptoms of worn exhaust mounts on the Serena?
Common clues include a new rattle at idle, thumps over bumps, a droning tone on the motorway, or a tailpipe that sits off-centre. A visual check may reveal stretched or split rubbers or the muffler touching a heat shield. Addressing mounts early prevents stress on welds and joints.
