Parts for your 2012 Nissan Tiida-Exhaust mount

2012 Nissan Tiida exhaust-mounts (hangers) — purpose, service tips and when to replace

Exhaust-mounts (often called exhaust hangers or insulators) are absolutely fitted to the 2012 Nissan Tiida (C11). This is documented in Nissan’s factory Service Manual for the Tiida (section EX – Exhaust System), which specifies rubber mounting insulators and associated brackets for the front pipe, centre section and rear muffler. The Nissan electronic parts catalogue (FAST) and dealer parts listings also show multiple “Insulator–Exhaust” rubber mounts for the 2012 Tiida, confirming their use on this model.

On the Tiida, these rubber mounts suspend the exhaust under the car, letting it move slightly as the engine twists and the system heats and cools. That flex prevents droning in the cabin, stops metal-on-metal knocks over bumps, and helps keep the tailpipe sitting neatly under the bumper. When one or more mounts perish, stretch or tear, the system can sag, rattle, or tap against the body, crossmember or rear beam.

As part of routine servicing, it’s smart to inspect the mounts—especially on cars doing coastal kilometres in Aus or NZ where salt and moisture speed up rubber ageing. Look for cracks, splits, hardening, elongation of the holes, or metal brackets going rusty.

• Common signs a mount’s on the way out:
  • Rattles or thumps from the rear over bumps or at idle
  • Exhaust sitting low, skewed, or touching a heat shield
  • More vibration in the cabin or a rubbery squeak

They’re inexpensive parts and usually there are three to four along the Tiida’s system. Replacement is straightforward, but do it safely:

1. Let the exhaust go fully cold, raise and support the car properly, and support the exhaust with a jack or stand.
2. Spray silicone lube on the old rubber to slide it off the pegs, avoid levering against thin heat shields.
3. Fit new OE-quality rubber insulators, check adjacent brackets and hardware, replacing any rusty bits.
4. Settle the system naturally, then tighten bracket fasteners to workshop spec and confirm clearances all round.

If a mount fails a WOF or RWC due to an insecure exhaust, replacing them as a set is often the best value. Polyurethane hangers can firm things up, but most owners stick with OEM-style rubber for the right NVH balance. After replacement, a quick road test over a few bumps will confirm the knocks and buzz have gone.

How often should exhaust-mounts be replaced on a 2012 Nissan Tiida?

There’s no strict interval, but checking them at every service (10,000–15,000 km) is sensible. In Aussie and Kiwi conditions, many last 5–10 years, replace as soon as cracks, elongation or sag appear, or if there’s any rattle or contact with the body.

What are the symptoms of a failing exhaust-mount on a Tiida?

Tell-tales include a droopy tailpipe, knocks over speed humps, a rattle at idle, or the exhaust touching heat shields or the rear beam. You might also feel extra vibration in the cabin. Visible splits or stretched rubber in the insulator are the clincher.

Can a handy owner replace the mounts at home?

Yes—if they have safe lifting gear and basic tools. Use stands, let the exhaust cool, support it, and lubricate the old rubber to remove it. Fit like-for-like mounts and double-check clearances. If brackets are rusty or seized, a workshop is the better bet.
