Removing the starter Nissan Almera N16 - This is a task that even a novice car enthusiast can handle if he has the necessary tools at hand and a little patience. The location of the unit in the engine compartment is quite specific, which often raises questions among owners when trying to remove it.
Unlike many modern cars, where access to the starter is blocked by complex ergonomics, Almera N16 With a QG series engine, space allows you to work quite freely, but there are some nuances. You will need to disconnect the battery, remove the air intake, and possibly remove other attachments to gain easy access to the mounting bolts.
Preparation of the workplace and necessary tools
Before starting any work under the hood, you need to make sure the process is safe. First, disconnect the negative terminal from the battery to prevent a short circuit when working with the starter electrical connectors.
You will need a standard set of wrenches, but pay special attention to the 10, 12 and 14 mm sockets, since these are the ones that secure the assembly. For work in confined spaces, universal joint adapters and extensions are ideal, allowing you to reach the lower mounting bolts without removing the engine.
- 🔧 Set of socket heads (from 8 to 17 mm) with extension
- 🔧 Ratchet wrench and ratchet for quick unscrewing
- 🔧 Flat-head and Phillips-head screwdrivers for removing clamps
- 🔧 Rags and wire brush for cleaning contact pads
If you plan not just to remove, but also to replace traction relay or the entire assembly, be sure to prepare a place to store the removed bolts so as not to lose them in the depths of the engine compartment.
Access to the unit and dismantling of attachments
On Nissan Almera N16 The starter is located at the bottom of the engine, on the gearbox side, closer to the center of the car. To gain direct access to it, you need to remove the plastic air duct and filter, and also unscrew the throttle assembly if it interferes with free access to the fasteners.
Owners often encounter a problem when the hoses of the crankcase ventilation system block the view. In such cases, it is better to carefully disconnect them from the fasteners, without completely removing them, in order to be able to return them to their place after completion of the work.
- 🚗 Remove the plastic air filter housing
- 🚗 Disconnect the ventilation pipes and fuel hoses (if they are in the way)
- 🚗 If necessary, loosen the throttle mountings
After freeing up the space, you will see the body starter, secured with two bolts to the gearbox housing. One of the bolts is often located in a hard-to-reach place, so use a cardan for easy access to the wrench.
☑️ Checking readiness for dismantling
Disconnecting electrical connections
The electrical part of dismantling requires special care, since the starter consumes enormous current when starting. First, disconnect the main power cable that goes to the bolt on the back cover of the traction relay. To do this you will need a 10 or 12 key, depending on the year of manufacture Nissan Almera.
The second step is to disconnect the control wire (thin wire), which sends a signal to the solenoid relay. You can simply pull it out of the connector; sometimes you need to pry the latch with a screwdriver. Be careful not to damage the wire insulation when removing.
- ⚡ Unscrew the nut of the main positive cable
- ⚡ Disconnect the solenoid relay control chip
- ⚡ Inspect the wires for cracks or oxidation
If the wires are heavily oxidized or damaged, this may cause starting problems even after installing a new unit. In this case, it is recommended to clean the contacts or replace the connectors.
⚠️ Attention: Never try to unscrew the power bolt without first removing the negative terminal of the battery, even if you are sure there is no voltage. A short circuit may cause sparking and fire.
What are the dangers of oxidized contacts on the starter?
Oxidation increases the resistance in the circuit, which leads to a voltage drop and weak armature rotation, even if the battery is fully functional.
The process of unscrewing the mounting bolts
The most crucial moment is unscrewing the bolts securing the housing to the block. The top bolt is usually accessible from above, and the bottom one is located deep below, sometimes it has to be turned from under the car if access from above is too limited.
Use extensions and universal joints to ensure the correct direction of force. If the bolt is stuck, do not use excessive force right away, it is better to treat the joint with a penetrating lubricant, such as WD-40, and give it time to work.
- 🔩 Unscrew the top mounting bolt using an extension
- 🔩 Clean the bottom bolt from dirt before unscrewing
- 🔩 Gently support the starter with your other hand when unscrewing the last bolt
When the last bolt is removed, the starter will begin to move. Be prepared to pick it up as it weighs quite a bit and could fall onto other parts or onto the garage floor, causing damage to the case or your shoes.
- Every 100 thousand km
- Once every 5 years
- Only in case of breakdown
- I don't know when it will be replaced
Removing the assembly from the engine compartment
Extraction starter requires care to avoid damaging surrounding hoses and wiring. Move the assembly up and slightly towards you, trying to disengage it from the gearbox. On some modifications Nissan Almera N16 A slight rocking of the body may be required.
If you are working in a pit, make sure that the starter does not get caught on the suspension components when being pulled out.
⚠️ Attention: When removing, be careful not to damage the speed sensor wiring or other cables running in the immediate vicinity of the starter mounting location.
The main difficulty in dismantling is working with the bottom bolt and getting the unit out of the narrow space without damaging the wiring.
Checking and installing a new starter
Before installing a new or repaired unit, be sure to clean the contact points on the engine block and transmission with a wire brush. This will ensure reliable electrical contact and eliminate ground problems.
Installation occurs in the reverse order of removal. First, carefully slide the starter housing into place, then tighten both mounting bolts. They must be tightened sequentially, alternating, to ensure uniform pressure.
- 🛠️ Clean the contact pads with a brush
- 🛠️ Fit the mounting bolts and tighten them with a torque wrench
- 🛠️ Connect the power cable and control connector
After connecting all the wires, do not rush to start the engine immediately. Visually check that no wires are twisted or touching rotating parts.
| Parameter | Meaning/Recommendation |
|---|---|
| Mounting bolts | 10 mm or 12 mm (depending on modification) |
| Power cable | Plus directly from the battery |
| Control wire | Solenoid relay connector |
| Tightening torque | 40-50 Nm (recommended for reliability) |
Before final tightening the bolts, check that the starter is level and not distorted, otherwise the gear may not engage the flywheel.
Typical replacement errors and their consequences
A common mistake is not checking the condition of the flywheel. If the flywheel teeth are chipped or worn, the new starter will quickly fail, even if it is in good working order. Be sure to inspect the ring gear through the crankcase window.
Another problem is incorrect wire connections. If the polarity is reversed or the power bolt is poorly tightened, the contact will heat up, which can lead to melting of the terminal and failure of the starting system at the most inopportune moment.
⚠️ Attention: If after replacing the starter the engine does not start, first check the reliability of the contact at the negative terminal of the battery and the engine ground.
Also, do not forget about the correct fixation of the connectors. On Nissan Almera N16 connectors often have fragile latches that can easily break if handled roughly. If the latch is broken, use a zip tie or electrical tape to prevent it from unplugging.
FAQ: Frequently asked questions
Do I need to remove the transmission to replace the starter?
No, on Nissan Almera N16 The starter can be removed without dismantling the gearbox. It is enough to unscrew the two fastening bolts, access to which becomes available after removing the air filter and part of the attachment.
How to check the starter before installation?
The starter can be tested on a bench by applying power directly from the battery to the power terminals. If the armature rotates and the bendix extends, the assembly is working. Also check that there is no play in the shaft.
Is it possible to lubricate the starter Bendix?
The Bendix cannot be lubricated, as oil will flow onto the flywheel gear, causing it to slip. It is allowed to apply graphite lubricant only to the shaft where it exits the housing, but not to the gear.
Which starter is better to install on Almera N16?
It is recommended to use original spare parts or high-quality analogues from trusted brands (for example, Denso, Bosch). Cheap Chinese analogues often have low service life and unreliable retractor relays.
