Nissan Note: detailed review of the bottom design and photo from below

Introduction to Underbody Construction

Many owners of class B crossovers and hatchbacks often wonder what exactly the car looks like Nissan Note below, especially before purchasing a used copy or when choosing a protection package. Studying photographs of the bottom allows you to assess the condition of the anti-corrosion coating, the integrity of the fuel lines and the condition of the suspension elements that are hidden from view during normal viewing.

For owners Nissan Note For second and third generations, it is critical to understand the differences in exhaust system layout and fuel tank location, as this directly affects the choice of accessories. Errors in self-diagnosis can lead to missing hidden defects, which over time will cause costly repairs.

When inspecting from below, special attention should be paid to the fastening of the fuel tank and the condition of the exhaust system corrugations, since these elements are most susceptible to corrosion in an aggressive urban environment.

Suspension and steering design

At the bottom Nissan Note The most noticeable element is the independent suspension, which provides a comfortable ride on rough roads. The front McPherson strut is equipped with an anti-roll bar, which is attached to the arms through special bushings, which often require replacement when the mileage exceeds 100,000 km.

The rear suspension, depending on the modification, can be either a semi-independent beam or a multi-link system, which significantly changes the appearance of the car from below. The beam looks like a solid structure, while the multi-link system consists of many separate elements that are easier to replace individually when the silent blocks wear out.

• 🔧 Silent blocks front control arms require regular checking for cracks and delamination of rubber.
• 🔧 Stabilizers lateral stability bars often break at the junction with the struts when driving through deep holes.
• 🔧 Ball joints are a critical element, the failure of which can lead to loss of controllability.

Steering rack Nissan Note located in a protected space, but its anthers are often damaged by stones or road debris. When inspecting from below, you must make sure that there are no oil leaks from the steering mechanism, as this is a sign of wear on the seals or damage to the housing.

It is important to note that the suspension geometry in the lower part of the body Nissan Note designed to minimize the risk of dirt getting on the brake discs. However, when installing non-standard wheel rims, this gap may decrease, which will lead to accelerated contamination of the brake system.

Exhaust system and thermal protection elements

Exhaust system Nissan Note runs along the central part of the bottom and is attached to the body through rubber hangers. The photo below clearly shows how the manifold goes into the exhaust pipe, and then into the muffler, located closer to the rear bumper.

The exhaust system insulation is made of thin aluminum sheet, which can peel off or become deformed over time when exposed to high temperatures. This is especially true for models with turbocharged engines, where the exhaust gas temperature is much higher.

• 🚫 Catalyst in the standard system it is located close to the engine, which requires careful inspection for burnouts.
• 🚫 Corrugation between the manifold and the pipe often breaks due to vibrations, causing extraneous sounds when the engine is running.
• 🚫 Rear muffler has thick walls, but can be subject to corrosion from the inside due to condensation.

When inspecting from below, you need to pay attention to the condition of the clamps and fastenings of the exhaust system. Loose fastenings can cause the muffler to bang against the body, causing an unpleasant rumble and possible damage to the heat shields.

Some owners Nissan Note install additional heat shields to protect the plastic elements of the bottom from overheating. This is especially important in winter, when snow accumulates under the bottom, which can melt from the heat of the exhaust system and cause corrosion.

⚠️ Attention: When replacing the exhaust system with a non-standard one, be sure to check the gap to the heat shields and plastic body elements to avoid fire.

Fuel system and tank placement

Fuel tank Nissan Note has a complex shape adapted to the geometry of the body and the location of other components. It is located under the rear seat and is protected by a metal shield, which also serves as heat protection from the exhaust system.

The photo below shows that the fuel tank has a plastic construction, which reduces its weight and increases corrosion resistance. However, plastic is more sensitive to mechanical shock, so installing crankcase protection is a mandatory recommendation for owners operating the car off-road.

• 🛢️ Fuel pump located at the top of the tank and has an electrical connector that must be sealed.
• 🛢️ Fuel lines run along the bottom and are protected from damage by metal corrugations.
• 🛢️ Filler neck has a back pressure valve that prevents the tank from overfilling.

The fuel tank is secured using metal straps, which can rust and lose strength over time. When inspecting from below, it is necessary to check the integrity of these fasteners, since unscrewing the tank can lead to rupture of the fuel hoses and a fire.

Hybrid models may have a smaller fuel tank and a different location to make room for the high-voltage battery. This requires special attention when choosing underbody protection, since standard solutions may not be suitable.

Features of hybrid models

In hybrid versions of the Nissan Note, elements of the battery cooling system and power electronics are also located under the bottom, which require additional protection from moisture and shock.

Brake system and drive elements

Brake system Nissan Note photographed from below, shows the classic layout: front disc brakes and rear disc or drum brakes, depending on the year and configuration. The brake lines pass through protective channels on the body.

The front calipers are attached to the steering knuckles and have guides that require regular lubrication. Rear brakes on drum versions are hidden under a housing, making it difficult to visually inspect pad wear without removing the wheel.

The drive shafts (axle shafts) are visible from below as metal rods connecting the transmission to the front wheels. At their ends, constant velocity joints (CV joints) are installed, protected by rubber covers.

• 🔩 Brake discs should have even wear and no deep grooves.
• 🔩 Brake hoses must not have cracks, swelling or signs of brake fluid leakage.
• 🔩 CV joint covers must be intact, since dirt getting inside the hinge leads to its rapid destruction.

The presence of an anti-lock braking system (ABS) is visible through the wiring and sensors installed on the wheel hubs. These sensors often become contaminated with metal shavings and dirt, which can lead to system errors.

⚠️ Attention: When replacing the front brake pads, be sure to check the condition of the caliper guides, as their jamming leads to uneven wear of the discs.

Comparative analysis of generations from below

First generation Nissan Note (E11) has a simpler underbody design with a simplified exhaust system and less developed element protection. The second generation (E12) received improved aerodynamics, which was reflected in the shape of the plastic fender liners and protective screens.

The third generation (E13) with the CMF-B platform demonstrates an even higher degree of protection and the use of composite materials. The difference in the design of the suspension and the location of the units makes it impossible to use parts from old models on new ones.

Generation	Rear suspension type	Tank material	Protection Features
E11 (2005-2013)	Semi-independent beam	Plastic	Minimal protection, exposed elements
E12 (2013-2020)	Semi-independent beam	Plastic	Improved screens, exhaust protection
E13 (2020-present)	Multi-link	Plastic	Comprehensive protection, aerodynamic elements
Hybrid (e-POWER)	Semi-independent/multi-link	Plastic (reduced)	Electronics and battery protection

When buying a used car, it is important to take into account that restyled versions may have slight changes in the design of the underbody, for example, the relocation of sensors or a change in the shape of the exhaust pipe. This affects the compatibility of accessories and spare parts.

Owners Nissan Note It is often noted that on the secondary market there are specimens with low-quality anticorrosive, which was not applied in a factory manner. Photos from below of such cars show uneven coating and traces of rust in hard-to-reach places.

Recommendations for protection and maintenance

Installing metal or composite crankcase protection is one of the most effective ways to extend the life of components Nissan Note. Metal sheets with a thickness of 3 mm or more provide maximum protection against rocks and ice, but can create extra noise and weight.

Composite protection is lighter and does not transmit vibration to the body, but requires careful installation, since the plastic can crack under a strong impact. It is important to choose the right protection model for a specific engine and gearbox so as not to block access to the drain plugs.

Regular washing of the bottom in winter helps remove reagents and salt, which accelerate metal corrosion. Particular attention should be paid to the internal cavities of the thresholds and arches, where dirt and moisture accumulate.

• 🧹 High pressure washer must be carried out with care to avoid damaging the insulation and electrical connectors.
• 🧹 Anti-corrosion treatment It is recommended to carry out inspection of hidden cavities every 2-3 years.
• 🧹 Visual inspection After off-road driving, it allows you to notice dents and damage in time.

When choosing protection, it is important to consider the vehicle's ground clearance. Nissan Note has sufficient ground clearance, but installing thick protection can reduce it, which will lead to hitting obstacles.

⚠️ Attention: Incorrectly installed crankcase protection can block access to the oil drain or damage the radiator in the event of a strong impact, so trust installation only to professionals.

In some cases, owners choose protection made from carbon or Kevlar, which combine the strength of metal with the lightness of plastic. Such solutions are more expensive, but provide a better level of protection and aesthetics.

Do not forget to check the condition of the protection fasteners after each trip on bad roads. Loose bolts can cause the guard to fall off and get stuck between the wheel and the body, which is dangerous for other road users.
