In this article we will analyze in detail the architecture of the engine compartment, consider the features of access to technical fluids and study the typical problems that users of this model encounter. You will learn what elements you need to pay attention to first when doing your own inspection.
General architecture of the engine compartment
When looking at Nissan Almera G15 with the hood open, the symmetrical layout typical of the B0 platform on which this model is built is striking. The engine, depending on the modification, can be equipped with an injection system multi-point injection or more modern solutions, but the general layout of the nodes remains unchanged. To the right of the driver (when looking at the engine) the fuse and relay box is traditionally located, which makes it easier to access the electrics if it is necessary to replace a fuse.
The central part is occupied by the power unit, covered with a plastic decorative shield, which not only performs an aesthetic function, but also protects the components from splashes and dust. On the left is the battery, which is often difficult to access due to the presence of protective covers or mounts that require careful removal. It's important to note that, unlike some competitors, Nissan Almera The battery is not always easily accessible without first removing the plastic covers.
Particular attention should be paid to the cooling system, the radiator of which has fairly large dimensions for effective heat removal in urban mode. The air intake is positioned to minimize the entry of dust and moisture into sensitive electronic components. The correct organization of air flows in the engine compartment of the G15 ensures stable operation of the air conditioner even in the summer heat.
Engine and main systems
With my heart Nissan Almera G15 The most common engine is a 1.6-liter gasoline engine (HR16DE series), which is highly maintainable and economical. This unit is equipped with a timing chain drive, which theoretically should eliminate the need for regular belt replacement, however, the condition of the tensioner and the chain itself requires periodic monitoring. Engine power varies between 102–106 hp, which provides decent dynamics for city traffic.
The lubrication system includes an oil filter, access to which may be somewhat limited due to the proximity of the subframe and other chassis components. When changing the oil, it is necessary to use specialized tools to unscrew the filter, since standard wrenches may not fit due to the tight arrangement. It is also important to monitor the oil level using the dipstick, which is located in a convenient location but requires cleanliness for an accurate reading.
The intake system is equipped with an electronically controlled throttle valve, which over time can become contaminated with carbon deposits, resulting in unstable idle speed. Regular cleaning of this part is mandatory to maintain engine performance. The exhaust system begins with a manifold, which is rigidly attached to the cylinder block, and extends down under the car, avoiding complex bends.
⚠️ Warning: Extreme caution should be used when working on a hot engine as exhaust system components and turbochargers (if installed) can reach temperatures that can cause serious burns even through protective shields.
Cooling system and electrical equipment
Cooling system Nissan Almera G15 built according to the classical scheme using a liquid radiator and an electric fan, which operates automatically when a certain temperature is reached. The expansion tank is made of translucent plastic, which allows you to visually monitor the coolant level without having to open the cap. The radiator cap is equipped with a pressure relief valve, which is critical to preventing the system from boiling over.
The electrical equipment is represented by a massive fuse box located on the right side of the engine compartment, and an additional unit under the hood responsible for power circuits. Wiring is made using waterproof connectors, however, over time, oxidation of the contacts can lead to problems with starting or operating the sensors. The battery is mounted on a special platform, which is often subject to corrosion due to exposure to reagents and moisture.
Diagnosing electrical problems often requires access to controller connectors, which may be hidden under plastic panels. The generator is located at the bottom of the engine and is driven by a V-belt.
- ✅ Check the antifreeze level in the expansion tank regularly, especially before the start of the heating season.
- ✅ Inspect the condition of the generator belt for cracks and tension, as its breakage will stop charging.
- ✅ Clean the battery contacts from oxides using a special lubricant to prevent corrosion.

Maintenance and diagnostics
Scheduled maintenance of the engine compartment Nissan Almera G15 requires a number of procedures that are best carried out in accordance with the manufacturer’s regulations. Oil and filters should be changed every 10-15 thousand kilometers, depending on operating conditions and the quality of the fuel used. It is important to use oils that meet the specifications API SN or higher to ensure maximum protection of engine parts.
Diagnostics of car systems can be carried out either using a professional scanner or visually. Many owners forget about the need to check the condition of the cooling system pipes, which over time can become hard and begin to leak. It is also worth paying attention to the fastening of all elements, since engine vibration can lead to loosening of bolted connections.
To independently check the functionality of the ignition system, you can use a multimeter to measure the resistance of the spark plugs or coils. If the engine is running rough, you should check the condition of the air filter, which may be clogged with dust and impede the normal flow of air. If you detect any extraneous noise or knocking in the engine compartment, it is recommended to immediately contact a service center.
