Without proper preparation and knowledge of the nuances, you may encounter broken plastic clips, damaged wiring, or problems during reassembly.
In this article we will look at the disassembly process step by step - from removing bumpers and doors to dismantling the instrument panel and suspension elements. You will find out what tools are requiredwhere hidden fasteners are located, and how to avoid common mistakes. The material will be useful to both beginners and experienced car owners planning independent repairs or modernization Micra K12.
Preparing for Disassembly: Tools and Safety Precautions
Before starting work, you must collect a complete set of tools. The absence of even one key or screwdriver can stall the process for several hours. Here minimum setwhich will be required:
- 🔧 Set of sockets and ratchet wrenches (sizes 8–19 mm)
- 🔨 Screwdrivers: Phillips (PH2), flat, Torx (T20, T25, T30)
- 🗝️ Plastic clip remover (required!)
- 🔩 Torque wrench (for critical threaded connections)
- 🧲 Magnet on the telescopic handle (for finding fallen bolts)
- 📸 Camera or smartphone (to record the location of parts)
Pay special attention plastic clips - in Micra K12 they often break when dismantled carelessly. Purchase spare parts in advance (items: 90510-4M000 for large clips, 90513-4M000 for small ones). Also prepare WD-40 or an analogue for processing rusted bolts - especially important for cars with a mileage of more than 150 thousand km.
⚠️ Attention: Do not proceed with disassembly if the car has been standing in the rain for less than 12 hours. Moisture in the interior and under the hood can cause a short circuit when the battery is disconnected. Dry the car or use a heat gun.
Before starting work, be sure to:
- Disable negative battery terminal (10 mm wrench).
- Drain the fuel to below ¼ tank level (if you plan to remove the gas tank).
- Secure the vehicle on level ground using wheel chocks.
- Interior (dashboard, seats)
- Body (bumpers, doors)
- Suspension and chassis
- Engine and transmission
- Electrical and wiring
Removing the front and rear bumpers: hidden fasteners and life hacks
Bumpers Nissan Micra K12 secured with a combination of bolts and plastic clips. The main difficulty is hidden fastenings under the headlights and in the wheel arches. Let's start with the front bumper:
- Dismantle radiator grille (4 clips on top, 2 bolts on bottom under license plate).
- Unscrew the bolts securing the bumper to the subframe (2 pcs., 10 mm head).
- Find 2 plastic clips in the wheel arches (use a puller!).
- Carefully pull the bumper towards you, starting from the corners - it is held in place by 4 latches in the center.
The rear bumper is easier to remove, but there is a nuance here: under the lights there are additional bolts (8 mm head), which are often forgotten to unscrew. If the bumper doesn't budge, check them!
| Detail | Number of fasteners | Fastener type | Tool |
|---|---|---|---|
| Front bumper | 12 (6 bolts + 6 clips) | Bolt M6, clip 90510-4M000 | 10 mm socket, clip remover |
| Rear bumper | 8 (4 bolts + 4 clips) | Bolt M5, clip 90513-4M000 | 8 mm socket, PH2 screwdriver |
| Side moldings | 5 clips per side | Clip 90512-4M000 | Plastic puller |
After removing the bumpers, we recommend cleaning the drainage holes in the wheel arches - in Micra K12 they often become clogged with dirt, which leads to corrosion of the thresholds. Use wire with a diameter of 3–4 mm.
Before installing the bumper back, apply silicone grease to the plastic latches - this will make future disassembly easier and prevent squeaks.
Removing doors: how not to damage window lifters and wiring
Removing doors in Nissan Micra K12 Requires caution due to fragile window and speaker wiring. Let's start with preparation:
- 🔧 Open the door and unscrew the hinge bolt from below (12 mm head).
- 🔨 Remove the plastic door trim (3 clips + 1 bolt under the handle).
- 🔌 Disconnect the wiring connectors (marking:
B12for window lifter,B14for speaker). - 🚪 Holding the door, unscrew the top hinge bolt (12 mm head).
Important point: don't pull the door towards you — first lift it up 2–3 cm to disengage it from the loops. Otherwise, the window lifter guides may be bent.
If you plan to completely disassemble the door (for example, to replace glass or mechanism), follow the checklist:
☑️ Nissan Micra K12 door disassembly
⚠️ Attention: At the door Micra K12 With the electrical package, the wiring goes through the corrugation in the rack. When reassembling, make sure that the corrugation is not twisted - this will lead to a break in the wires when the door is closed.
For clarity, here is a diagram of the location of the door trim clips (relevant for models 2005–2010):

Interior disassembly: instrument panel, seats and electronics
Salon Nissan Micra K12 It can be disassembled on a modular basis, but there are several pitfalls. Let's start with front instrument panel:
- Remove the steering wheel (unscrew the 19 mm nut, having first installed the wheels straight).
- Remove the trim around the radio (2 clips from below, PH2 screwdriver).
- Unscrew the panel mounting bolts (4 pieces under the dashboard, 10 mm head).
- Disconnect the connectors
E24(backlight),E26(wiring buttons).
Pay special attention climate control unit — its fastenings often break during careless dismantling. Use a plastic puller to release the clamps.
When disassembling the seats, remember:
- 🪑 The front seat is attached with 4 bolts (14 mm head) + heating connector (if any).
- 🛋️ The rear seat is held on by 2 latches at the front - pull up with a force of ~15 kg.
- 🔌 Seat belt sensor connectors are located under the seats (
S12AndS13).
How to remove the glove compartment without breaking it?
In the glove compartment Micra K12 on the right there is a hidden bolt under a plastic plug (screwdriver PH1). After unscrewing it, the glove compartment moves forward and is disconnected from the guides. Do not pull it down - this will break the plastic clips!
When working with electronics, be sure to:
⚠️ Attention: Do not disconnect the connectors of the engine control unit (ECU) with the ignition on - this may lead to reset of adaptations and an error P1614 (reset via Consult-III).
Removing suspension elements: struts, arms and hubs
Disassembling the chassis Nissan Micra K12 Requires a torque wrench and knowledge of tightening torques. Let's start with front pillars:
- Loosen the shock absorber rod nut (17 mm head) with the suspension loaded.
- Unscrew the 2 bolts securing the strut to the steering knuckle (14 mm head).
- Remove the 3 support bearing bolts (12mm socket).
- Remove the strut assembly with the spring (weight ~8 kg).
Tightening torques for front suspension:
| Detail | Tightening torque (Nm) | Note |
|---|---|---|
| Shock absorber rod nut | 40–50 | Tighten with loaded suspension |
| Bolts securing the strut to the knuckle | 80–90 | Replace whenever dismantled |
| Support Bearing Bolts | 20–25 | Use new bolts |
When disassembling rear suspension please note:
- 🔧 The lever mounting bolts (17 mm head) often stick - use penetrating lubricant 12 hours before work.
- 🔩 The hub nuts (30 mm head) have a left-hand thread on the right side and a right-hand thread on the left.
- 🛠️ Wheel bearings in Micra K12 non-separable - when worn, replace as an assembly (article:
40520-BM400).
When replacing silent blocks of the rear levers, be sure to check the play of the stabilizer bushings - their wear accelerates the destruction of new silent blocks by 2-3 times.
Disassembling the engine and gearbox: what can be done without a lift
For engine overhaul HR15DE (1.5 l) or CR14DE (1.4 l) will require a lift, but some operations can be performed in a garage. For example, timing belt replacement:
- Remove the right front wheel and plastic shield.
- Secure the crankshaft with a bolt (19 mm head) through the hole in the block.
- Loosen the tension roller (14 mm wrench) and remove the belt.
- Check the condition of the pump - if the play is more than 0.5 mm, replace it.
For manual transmission (RS5F91V) available without lift:
- 🔧 Replacing the clutch (removing the box will be required, weight ~45 kg).
- 🔩 Adjusting the gearshift cable (10 mm nut under the hood).
- 🛠️ Replacing drive seals (article:
38345-3M000).
When working on the engine, remember:
⚠️ Attention: B Micra K12 with HR15DE When removing the cylinder head, you cannot use standard bolts for fixation - they are 5 mm shorter than the bolts CR14DE. Using unsuitable bolts will damage the threads.
For clarity, the tightening torques of critical connections:
ГБЦ: 25 Н·м (1-й этап) → 60 Н·м (2-й этап)
Маховик: 80–90 Н·м
Крышка подшипников: 45–50 Н·м (последовательно от центра)
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes when disassembling Nissan Micra K12. Here are the most common:
- Damage to wiring when removing doors - always disconnect the connectors to dismantling, not after.
- Lost subframe bolts - in Micra K12 they have different lengths (front: 80 mm, rear: 100 mm).
- Incorrect installation of strut springs — the upper turn should rest against the protrusion of the support bearing.
- Ignoring timing marks - on HR15DE the mark on the crankshaft pulley must coincide with the mark on
9 o'clock(when viewed from the front).
To avoid problems, follow the rule "three checks":
- 🔍 Check it out to dismantling (photos, marks, location of parts).
- 🔧 Check it out during (condition of threads, integrity of seals).
- 🔩 Check it out after assemblies (plays, system performance).
If after assembly there are extraneous sounds, use the diagnostic table:
| Symptom | Probable Cause | Solution |
|---|---|---|
| Creaking sound when turning the steering wheel | Support bearing wear | Replacing the bearing (part number: 40510-3M000) |
| Knock in the front suspension | Play in silent blocks of levers | Replacing silent blocks (article: 54503-3M000) |
| Vibration at speeds of 80–100 km/h | Wheel imbalance or worn CV joints | Balancing or replacing the CV joint (article: 39310-3M000) |
