Exhaust system resonator Nissan Terrano 2014 - a critical element responsible for reducing noise and optimizing exhaust gas flow. Its malfunction is manifested by a characteristic hum, vibration, or even loss of engine power. Owners of this crossover often have to deal with corrosion or mechanical damage to the resonator, especially when operating in aggressive conditions (salty roads, off-road). In this article we will look at how to choose the right part according to article number, which analogues are compatible with the original, and what to consider when replacing.

Feature Terrano 2014 model year - unification of many components with Renault Duster And Nissan Almera, which expands the selection of spare parts. However, not all analogues fit perfectly: fastenings, pipe diameters, or even the shape of the body may differ. We analyzed manufacturers' catalogs and reviews from car owners to compile an up-to-date list of part numbers and give practical recommendations for installation.

Original resonator articles for Nissan Terrano 2014

Official resonator from Nissan Available under several articles depending on the configuration and market. For European version Terrano 2014 (with engines H4M 1.6 l or K9K 1.5 dCi) the following numbers are relevant:

  • 🔧 205C0-JM00A — basic version for petrol modifications (1.6 l, 114 hp). Fits most trim levels including Comfort And Tekna.
  • 🔧 205C0-JM00B — modification for diesel engines K9K (1.5 dCi, 110 hp). It features reinforced fastenings and a heat-resistant coating.
  • 🔧 205C0-4M500 — option for the markets of Asia and the Middle East. Compatible with Terrano 2014–2016, but may require modification of fasteners.

Original parts are produced by the company Yutaka Giken (Japan) and supplied in original packaging Nissan with a hologram. The cost of a new resonator in official dealership centers ranges from 8,500 to 12,000 rubles (for 2026). When ordering through online stores (for example, Exist.ru or Autodoc) the price may be 15–20% lower, but the risk of running into a fake is higher.

⚠️ Attention: When purchasing an original resonator, check for the presence of an engraving with the article number on the body. Counterfeits often come unmarked or with blurred symbols.

Resonator analogues: what to choose instead of the original

If the budget is limited or the original part is not available, you can consider analogues from trusted manufacturers. The main thing is to ensure compatibility in the following parameters:

  • 📏 Pipe diameter (standard for Terrano - 50 mm at the inlet/outlet).
  • 🔗 Mounting type (flange or clamp). The original uses flanges with 4 holes for M8 bolts.
  • 🔥 Heat resistance (for diesel versions minimum 650°C).

The table below shows the best analogues, indicating their article numbers and average prices:

Manufacturer Article Compatibility Price, rub. Features
Bosal 254-508 Gasoline 1.6 l 4 200–5 500 Aluminized coating, 2 year warranty
Walker 20595 Diesel 1.5 dCi 5 800–7 200 Reinforced welding, comes with new gaskets
Eberspächer 93553600100 All modifications 6 500–8 000 Stainless steel, resource up to 100,000 km
Magneti Marelli 110556000120 Gasoline/diesel 5 000–6 300 Optimized for European standards Euro 5

When choosing an analogue, pay attention to certification. Parts without markings ECE R10 or ISO 9001 often have thin-walled pipes that burn out in 1–2 years. It is also worth checking the package: the box should contain new gaskets, clamps and bolts (if they do not come in a separate set).

💡

Before purchasing an analogue, compare the photographs of the mounts on the seller’s website with your old resonator. Even if the article number is the same, the bending angles of the pipes may differ.

Signs of a resonator malfunction: when is it time to change it

Resonator Nissan Terrano rarely fails suddenly - problems usually accumulate gradually. Here are the key symptoms indicating the need for replacement:

  • 🔊 Increased noise from under the bottom, especially at idle or during acceleration. The sound may resemble a "booming" or metallic clanging sound.
  • 💨 Extraneous vibrations, transmitted to the body or steering wheel. Often accompanied by rattling in the rear suspension area.
  • 🚗 Decreased dynamics: the car accelerates worse, “dips” appear when accelerating.
  • 🌫️ Visible damage: Corrosion, cracks or holes in the resonator body (can be detected by inspection on a lift).

A critical sign is the appearance of condensation or oily streaks on the resonator body. This indicates the destruction of the internal partitions and requires immediate replacement, since further operation may damage the catalyst.

To diagnose, just start the car and listen to the sound of the exhaust. If the noise becomes louder than usual, or a metallic tint appears, the resonator needs to be checked. It is also worth inspecting the junction of the resonator with the muffler: rust often accumulates there or traces of burnout are visible.

⚠️ Attention: If you ignore the resonator malfunction, increased exhaust gas resistance can lead to engine overheating and failure of the lambda probe (oxygen sensor). The cost of replacing the sensor is from 3,000 rubles, plus error diagnostics P0420 or P0430.

Step-by-step instructions for replacing the resonator

Replacing the resonator with Nissan Terrano 2014 does not require special equipment and can be done independently if you have an inspection hole or a lift. On average, the procedure takes 1.5–2 hours. Here's what you'll need:

  • 🔧 Set of sockets (10, 12, 14 mm) and extension.
  • 🔧 WD-40 or similar penetrating lubricant (for rusty bolts).
  • 🔧 New gaskets (item no. 205C0-4M510 for petrol versions).
  • 🔧 Jack and stops (if there is no hole).

Sequence of actions:

  1. Preparation. Stop the engine and allow the system to cool (at least 30 minutes). Jack up the rear of the car and secure it with jack stands.
  2. Removing protection. Remove the plastic engine protection (4 x 10 mm bolts) and the heat shield (if equipped).
  3. Detaching fasteners. Treat the flange connection bolts with WD-40 and unscrew them with a 14 mm socket. If the bolts are stuck, use an impact wrench.
  4. Removing the old resonator. Carefully remove the resonator from the rubber hangers, supporting it from below (weight ~5 kg). Do not pull on the pipes - you can damage the corrugation.
  5. Installing a new one. Check the integrity of the gaskets and install the resonator in reverse order. Tighten the bolts crosswise with a force of 25–30 Nm.

Check the completeness (gaskets, clamps)

Clean flanges from rust and dirt

Apply graphite lubricant to bolt threads

Make sure the rubber hangers are not torn-->

After replacement, start the engine and check the tightness of the connections. If installed correctly, there should be no gas leaks (determined by hearing or smell). It is also recommended to reset ECU errors using a diagnostic scanner (for example, ELM327), if they appeared earlier.

What to do if the flange bolts break off?

If the resonator mounting bolts have broken off, they can be drilled out with a metal drill (Ø6–8 mm), then a new thread can be cut using an M8 tap. An alternative is to use bolts with nuts and locknuts if space allows.

Common replacement mistakes and how to avoid them

Even experienced car owners make mistakes when replacing the resonator, which lead to repeated breakdowns or leaks. Here are the most common mistakes:

  • 🛠️ Using old gaskets. Rubber or metal gaskets lose their elasticity after dismantling. Their repeated use leads to air leaks and errors. P0420.
  • 🛠️ Insufficient tightening of bolts. Over time, loose fasteners begin to rattle, which accelerates the wear of rubber hangers.
  • 🛠️ Ignoring the corrugation. If the exhaust system corrugation is damaged, the new resonator will not last long due to increased vibrations.

Another typical mistake is purchasing a resonator without taking into account engine modifications. For example, diesel K9K requires parts with reinforced partitions, since the temperature of the exhaust gases is higher than that of gasoline H4M. Installing a “gasoline” resonator on a diesel engine will lead to its rapid burnout.

⚠️ Attention: After replacing the resonator, be sure to check the operation of the lambda probes. If the sensors worked for a long time with a faulty resonator, their readings could be distorted. If necessary, adapt the sensors using diagnostic equipment.
💡

When replacing the resonator, always inspect the adjacent elements of the exhaust system: corrugation, catalyst and muffler. Their wear can shorten the life of the new part.

FAQ: answers to frequently asked questions

Is it possible to drive without a resonator?

Technically yes, but this will lead to:

  • Increased noise (up to 100 dB), which is contrary to traffic regulations (maximum 96 dB for passenger cars).
  • Increased load on the catalyst and muffler (they will fail faster).
  • Risk of damage to lambda probes due to gas turbulence.

A temporary solution is to install a “direct flow” (pipe without internal partitions), but this will worsen acoustic comfort.

Which resonator is better: original or analogue?

The original will last longer (lifespan ~150,000 km), but costs 2 times more than its analogues. Optimal choice:

  • For urban use - Bosal or Walker (price/quality balance).
  • Off-road - Eberspächer (stainless steel).
  • To save money - Magneti Marelli (good price-resource ratio).
Do I need to cut off the catalyst when replacing the resonator?

No, the resonator and catalyst are separate units. However, if the catalyst is clogged (error P0420), it may need to be replaced or removed in the near future. In this case, it is advisable to install a “spider” (a manifold without a catalyst) and modify the ECU firmware.

How often should the resonator be replaced? Terrano?

Service life depends on operating conditions:

  • City: 80,000–120,000 km.
  • Off-road/salty roads: 50,000–80,000 km.
  • Aggressive driving style: 40,000–60,000 km.

Regular washing of the bottom in winter extends the life of the resonator by 20–30%.

Is it possible to repair the resonator by welding?

Temporary repairs are possible if:

  • The crack is small (up to 2 cm) and is not located on the flange.
  • The body did not burn through.
  • Argon welding or cold welding with heat resistance ≥600°C is used.

However, such repairs rarely last longer than 6–12 months. For diesel versions, welding is not recommended due to high gas temperatures.
