Engine starting system in a car Nissan Almera generation G15 is a classic layout, where starter occupies a place in the tightest corner of the engine compartment. For many owners, replacing this unit becomes a real challenge, since the manufacturer has designed access to the unit to be extremely limited. The main difficulty is that the starter is located under the intake manifold, in close proximity to the exhaust manifold and suspension elements.
If you are faced with the fact that the car has stopped starting, and the diagnostics indicate a faulty starting device, do not rush to call a tow truck for service. In most cases, with the necessary tools and patience, you can remove the starter on one's own. However, it is important to understand that the procedure requires attention to detail, since incorrectly disconnecting contacts or dismantling attachments can lead to damage to neighboring units.
Preparation of the workplace and necessary tools
Before you begin any manipulations under the hood, it is necessary to ensure safe working conditions. Nissan Almera The G15 has a fairly cramped engine compartment, so access to the starter is often blocked by other elements. You will need a pit or lift, as some operations are easier to do from below, as well as a clean, well-lit space for working with bolted joints.
The list of tools should be as complete as possible so as not to interrupt the process of finding the right key at the most crucial moment. Pay special attention to the set of sockets and ratchets with extensions, since the starter mounting bolts are often located in hard-to-reach places. Not having the right extension can make removing a single nut a painful process.
- 🔧 Set of socket heads (from 8 to 19 mm) and ratchet wrench
- 🔧 Cardan extension and extender extensions (10-15 cm)
- 🔧 Phillips and flat blade screwdrivers (for removing clamps and clamps)
- 🔧 A prybar or a powerful lever for detaching stuck knots
- 🔧 Rags and oil remover (WD-40 or equivalent)
Don't forget about personal protective equipment. When working in the engine compartment, especially in the lower part of the engine, you will inevitably come into contact with dirt, oil and antifreeze residues. Gloves will protect your hands, and glasses will protect your eyes from getting chips or rust when unscrewing old bolts.
Dismantling of obstructing components and assemblies
The first step is always to de-energize the system. Disconnect the negative terminal of the battery to eliminate the risk of a short circuit when working with the electrical contacts of the starter. This is a critically important stage, since even accidentally touching the body with the key while unscrewing the positive terminal can lead to a serious accident.
To access the starter on Nissan Almera G15 most often you have to remove the intake pipe and part of the air filter. This must be done carefully so as not to damage the plastic clips and the mass air flow sensor (MAF). After removing the pipe, you will be able to see the top of the starter and its mounting bolts.
If you plan to remove the entire starter, you may need to unscrew and remove the intake manifold itself, but this is a last resort. Usually it is enough to unscrew the connection pipe and move it to the side, securing it with wire or rope so that it does not interfere with work. It is also often necessary to loosen the fuel rail if it blocks access.
⚠️ Attention: When disconnecting hoses and pipes, be sure to mark their location or take a photo so that during assembly you do not confuse the connection locations, which can lead to incorrect engine operation.
Sometimes access is blocked not only by pipes, but also by elements of the cooling system. If the radiator or expansion tank is in the way, they also need to be carefully moved to the side, after draining some of the coolant, if necessary. The main thing is to prevent the hoses from chafing or deforming.

Disabling electrical circuits and fastenings
Once access to the starter housing is open, you can begin to disconnect the electrical wires. On Nissan Almera The G15 starter has two main connections: a power cable from the battery and a control cable from the ignition switch. The power wire is usually secured with a 13 mm nut, and the control wire with a smaller nut or connector.
Loosening the power terminal requires caution. If the nut is stuck, do not use excessive force to avoid stripping the threads on the stud. It is best to pre-treat the joint with penetrating lubricant and wait 10-15 minutes. After disconnecting the wires, they must be taken to the side and secured so that they do not dangle and interfere with the removal of the unit itself.
- ⚡ Disconnect the negative terminal of the battery before starting work
- ⚡ Loosen the nut of the power wire (usually 13mm) and remove it
- ⚡ Disconnect the control wire connector or terminal (pin 50)
- ⚡ Put the wires in a safe place so as not to damage the insulation
Next we move on to mechanical fastenings. The starter is usually held in place by two or three bolts. One of them is often located on top and is accessible through the openings of the intake manifold, and the second can be located below, on the side of the subframe. Accessing the bottom bolt may require working from underneath the vehicle, making a pit or lift a must.
⚠️ Attention: Starter bolts are often over-torqued and may be coated with dirt and rust. Use a high-quality wrench and reliable extensions to avoid stripping the bolt head.
☑️ Checking readiness for unscrewing
The process of removing the starter from the engine compartment
Once all the bolts are unscrewed and the wires are disconnected, you can begin to remove the starter. This is the most difficult stage, since space is extremely limited. Remove the starter the whole thing is often impossible due to interference with the exhaust manifold or suspension elements. You have to use cunning, slightly rocking the unit and changing its angle of inclination.
Sometimes it is necessary to remove an additional bracket or unscrew part of the engine mount to make room for maneuver. This should not be scary, since these manipulations are standard for repairing such units. The main thing is to act slowly and feel where exactly the unit clings to neighboring parts.
If the starter does not move, check whether you forgot to unscrew a bolt or whether the hose is in the way. Using a pry bar to lightly pry the unit can help, but do so with extreme caution to avoid damaging the starter housing or fragile engine components. In some cases it is easier to remove the starter from the top if there is enough space, but most often you have to pull it down and to the side.
What to do if the starter is stuck?
If the starter cannot be removed due to sticking, try gently tapping the housing with a hammer through a wooden spacer. This will help break down the corrosion layer and make removal easier. Do not hit electrical connectors!
When removing the unit, be careful not to drop the bolts inside the engine or under the car. Use a magnetic holder or grid to avoid losing small parts. Place the removed starter in a safe place for further inspection or replacement.
Table of technical characteristics and tightening torques
When installing a new or remanufactured starter, it is extremely important to follow the recommended bolt torques. Excessive force can lead to stripping of the threads in the cylinder head, and insufficient force can lead to vibrations and subsequent loosening of the fastener while the engine is running. Below are approximate values for the model Nissan Almera G15.
| Fastening element | Bolt size | Recommended torque (Nm) | Features |
|---|---|---|---|
| Starter mounting bolt (upper) | M10 | 35-40 | Access via intake manifold |
| Starter mounting bolt (lower) | M10 | 35-40 | Requires bottom access |
| Power wire nut | M8 | 10-12 | Do not overtighten to avoid breaking the pin. |
| Control wire nut | M6 | 5-7 | Plastic insert, requires care |
Compliance with these parameters guarantees reliable fixation of the node. Use a torque wrench if you have one. If not, tighten the bolts until you feel sure they stop, but without fanaticism. Remember that aluminum engine threads are very delicate.
Before installing a new starter, be sure to clean the seat on the cylinder block from dirt and rust. This will ensure a tight flange fit and prevent vibration during startup.
Installing a new node and checking its functionality
The process of installing a new starter is almost a mirror image of the removal process, but in reverse order. Place the unit in place, carefully inserting it into the seat. First, tighten all of the mounting bolts by hand to make sure they go in freely and the threads are not damaged.
Once all bolts are seated, tighten them to the recommended torque. Then connect the electrical wires: first the control, then the power. Don't forget to put the rubber protection on the power terminal if it has been removed. Make sure that the wires do not touch hot parts of the engine and are not strained.
Replace all removed components: intake manifold, air filter, brackets and fuel rail. Check that all hoses and clamps are securely attached. Connect the battery and check the starter operation. The engine should start the first time, without any extraneous sounds or vibrations.
- 🔩 Tighten the mounting bolts to the recommended torque
- 🔌 Connect the power and control wires
- 🔄 Reinstall the inlet pipe and filters
- 🔋 Connect the battery and check starting
⚠️ Attention: After installing the starter, be sure to check if there are any tools or unnecessary parts left in the engine compartment. A key or bolt left behind could become caught in the fan or drive belts, causing serious damage.
Correct installation of the starter and compliance with the bolt tightening torques are the key to long-term operation of the unit and absence of vibrations when starting the engine.
Common errors and maintenance tips
When replacing the starter themselves, owners Nissan Almera G15s often make common mistakes. One of the most common is an attempt to remove the starter without dismantling the intake manifold or pipe, which leads to damage to sensors or fragile plastic parts. Another mistake is using the wrong tools, which results in stripped threads or a broken bolt head.
It is also worth paying attention to the condition of the electrical contacts. If you are replacing only the starter, be sure to clean the battery terminals and power wires. Oxidation of the contacts can cause the new starter to work unstably or not work at all. Check the integrity of the wire insulation, especially at bends.
If you are not confident in your abilities or do not have the necessary equipment, it is better to entrust the work to professionals. However, if you decide to do everything yourself, remember that patience and accuracy are your main helpers. Removing the starter on a Nissan Almera G15 takes from 2 to 4 hours, depending on the experience of the technician and the condition of the car.
Regularly checking the condition of the starter and its fastenings will help avoid sudden breakdowns. Pay attention to unusual noises during startup and engine rotation time. Any deviations from the norm may indicate an incipient malfunction.
How long does it take to replace a starter on a Nissan Almera G15?
For an experienced technician, replacing a starter takes about 1.5–2 hours. For a beginner without experience working with this car, this process can take from 3 to 5 hours, since it will take more time to dismantle obstructing components and find the necessary tools.
Do I need to remove the intake manifold to replace the starter?
Usually it is enough to remove only the inlet pipe and move it to the side. Complete removal of the intake manifold is only required if access to the upper starter mounting bolt is completely blocked or if the manifold is very dirty and interferes with maneuvering.
Is it possible to remove the starter from above without a pit?
This is theoretically possible, but extremely inconvenient and risky. The lower starter mount is located in a hard-to-reach place, and without lifting the car or using a pit/lift, it is almost impossible to unscrew it properly. It is recommended to use a pit or lift.
What to do if the starter mounting bolts are stuck?
Before unscrewing, treat the bolts with a penetrating lubricant (such as WD-40) and wait 15-20 minutes. You can gently tap the bolt head with a hammer to break up the rust layer. If the bolt does not budge, use heat (propane torch) with caution, avoiding heating plastic parts and wiring.
