Diagnosing malfunctions in the engine starting system often leads to the need to dismantle the starter. By car Nissan Almera new generation (G15), this process has its own characteristics, determined by the layout of the power unit and access to the components. Many owners are faced with the fact that the unit is located in a hard-to-reach place, which requires careful preparation and the availability of specific tools.
Correct dismantling The starter allows you not only to replace it, but also to inspect the electrical connections, check the condition of the flywheel and ensure the integrity of the drive belts. Ignoring safety recommendations may result in injury or damage to fragile plastic components in the engine compartment. In this article, we will analyze each stage of the work so that you can complete the task efficiently and without extra costs for service station services.
Preparing the workplace and necessary tools
Safe conditions must be ensured before starting work. The vehicle must be parked on a level surface and the engine must be completely cool. To access the starter on the model Nissan Almera G15 Often it is necessary to remove some protection elements and the battery.
You will need a tool kit including 10, 12, 14 and 17mm sockets, as well as extensions and universal joints. Don't forget to use a torque wrench to properly tighten the mounting bolts. The absence of the necessary tool can delay the process or lead to thread failure on fasteners.

- 🔩 Torque wrench for final assembly
- 🔋 Set of keys for removing battery terminals
- 🔦 Powerful flashlight for illuminating hard-to-reach places
Pay special attention to lighting. In the engine compartment Nissan Almera There are many shadow areas where you can accidentally damage wiring or break a bolt. Make sure the light shines exactly on the starter mounting location.
Removing the battery and protective elements
The first step is always to de-energize the vehicle. Remove the negative terminal from the battery to eliminate the risk of a short circuit when working with the starter power wires. On Nissan Almera G15 The battery is located in a niche, access to which may be limited by body elements.
After turning off the power, it is necessary to dismantle the plastic protection of the engine compartment. It is attached with plastic clips and several bolts. Carefully pry up the clips so as not to break them, otherwise during assembly there will be problems with the tightness of the protection.
⚠️ Attention: Do not disconnect the positive terminal first! Remove the “minus” first, so as not to accidentally short the tool to the body when unscrewing the “plus”.
Some modifications may require removal of the air filter and throttle body to improve access. It depends on the year of manufacture and the specific configuration of the car.
Disconnecting electrical connectors and power cables
Access to the starter's electrical contacts is gained after removing the protective covers. Be extremely careful with the solenoid relay control connector. It has a latch that must be carefully pressed before removing the plug.
The power cable that goes directly from the battery to the starter has thick insulation and is secured with a nut. Use the correct size socket to avoid stripping the edges of the bolt. Loosen the nut, remove the cable and move it to the side, securing it so that it does not interfere with further manipulations.
- 💡 Disconnect the solenoid relay control connector
- ⚡ Remove the power cable from the starter terminal
- 🔌 Check the condition of the wire insulation before disconnecting
It is important to remember or photograph the location of all the wires so as not to confuse them when reassembling. On older vehicles, the markings may be worn off, making the process more difficult.
The process of unscrewing the mounting bolts
Starter on Nissan Almera G15 It is usually attached with two or three bolts to the gearbox housing. The top bolt is often hidden behind other components and requires the use of an extension. The lower bolt may only be accessible from below if you are lifting the car on a lift or inspection pit.
Use a universal joint to access angled bolts. If the bolts are very stuck, do not try to rip them out of place with a sharp jerk - use a penetrating lubricant and give it time to work. Broken threads on the engine block or gearbox will lead to costly repairs.
☑️ Tools for dismantling
Removing the assembly from the engine compartment
After unscrewing all the fasteners, the starter can be removed. Do this carefully to avoid damaging adjacent parts and wiring. The unit is heavy, so support it with your other hand when removing it.
You may have to turn the starter a little on its axis to get it out of the tight space. Estimate the trajectory of movement in advance. In some cases, it may be necessary to temporarily remove the engine mount, but Nissan Almera this is usually not necessary.
⚠️ Attention: When removing the starter, watch the bendix teeth so that they do not damage the flywheel or clutch basket.
What to do if the starter doesn't work?
If the starter is stuck, check to see if it is stuck against the exhaust manifold or hoses. Sometimes it is enough to slightly loosen the engine mounts to move the block slightly.
Checking and diagnosing the removed starter
Before installing a new or remanufactured starter, it is recommended that you perform a visual inspection of the removed assembly. Check the condition of the solenoid relay, the integrity of the windings and wear of the brushes. Often the problem lies not in the starter itself, but in poor contact or oxidation of the terminals.
Inspect the Bendix teeth - they should not be chipped or heavily worn. If the teeth are ground down, then even a new starter may not start the engine due to slipping. Also check the condition of the armature shaft for play and scoring.
- Brush wear
- Solenoid relay malfunction
- Bendix jamming
- Wiring problems
New starter installation and assembly
Installation is carried out in the reverse order of dismantling. First, carefully insert the starter into the seat and tighten the mounting bolts. Tighten them evenly to prevent the body from becoming distorted. Use a torque wrench to maintain the tightening torque.
Connect the power cable and control connector. Make sure that the contacts are tightly secured and have no play. After assembling all the elements, check the starter at idle speed. The engine should start quickly and without any extraneous sounds.
- ✅ Check the tightening torque of the mounting bolts
- ⚡ Make sure the power terminals are in good contact
- 🔋 Connect the battery and check the operation
Proper tightening of the starter mounting bolts is critical to prevent vibration and subsequent thread failure in the transmission housing.
Frequent errors and operating nuances
Many owners Nissan Almera They make the mistake of trying to start the engine by rotating the starter for a long time. This leads to overheating of the solenoid relay and its failure. The maximum operating time of the starter should not exceed 5-7 seconds, then a break is necessary.
It is also worth paying attention to the condition of the battery. A weak battery puts increased stress on the starter, which accelerates its wear. Regularly check the electrolyte density and voltage at the terminals.
⚠️ Attention: If after installing a new starter the engine does not start, check the presence of ground on the engine and the integrity of the fuses in the mounting block.
Before installing the new starter, apply a thin layer of graphite grease to the Bendix shaft splines for easy engagement and protection against corrosion.
