Removing the starter on a Nissan Sunny: detailed instructions for self-repair

Starter in Nissan Sunny - a unit that sooner or later requires attention: either the brushes will wear out, or the solenoid relay will begin to “be capricious,” or the bendix will jam. A car service center will charge from 3 to 8 thousand rubles for a replacement (depending on the model and region), but if you have the tools and patience, you can perform the procedure yourself. The main thing is to know exact sequence of actions and take into account the design features of a specific modification Sunny (B13, B14 or B15).

In this article you will find not only step-by-step instructions with photographs of key stages, but also list of required tools, a table of compatibility of starters for different engines, as well as an analysis of typical errors that lead to the breakdown of a new unit within a month after installation. If your Sunny “refuses” to start with a clicking sound or is completely silent when you turn the key - this instruction will help save time and money.

Preparing for dismantling: tools and safety precautions

Before you start removing the starter, make sure that this is the problem. Symptoms of malfunction: single click without cranking the engine (defective solenoid relay), metallic grinding (problems with bendix) or complete lack of reaction to turn the key. If the starter turns, but the engine does not start, look for the reason in the ignition system or fuel supply.

To work you will need:

• 🔧 Set of heads (required) 10 mm, 12 mm, 14 mm) and extension cord
• 🔧 Ratchet socket wrench (to access the bottom bolt)
• 🔧 Flat blade screwdriver (for disconnecting terminals)
• 🔧 Jack and stops (if you need to partially lift the car)
• 🔧 Multimeter (to check the voltage at the terminals)
• 🔧 WD-40 or similar composition (for treating acidified compounds)

⚠️ Attention: Before starting work, be sure to disconnect the negative terminal of the battery. B Nissan Sunny The positive wire of the starter comes directly from the battery - an accidental short circuit can lead to a fire in the wiring or failure of the computer.

If the vehicle has recently been driven, allow the engine to cool - the temperature of the exhaust manifold (near where the starter is located) may exceed 100°C. Also prepare marker or tape for marking wires and terminals - this will simplify reassembly.

Starter localization: where to look for the unit in Nissan Sunny

In most modifications Nissan Sunny (including the popular B14 and B15) starter is located at the bottom of the engine, gearbox side, next to the flywheel. The exact position depends on the motor type:

• 🔍 On motors GA14DE/GA15DE/GA16DE (1.4–1.6 l) starter attached two bolts to the clutch housing and is partially covered by a heat shield.
• 🔍 On SR16VE/SR20DE (1.6–2.0 l) access is complicated due to the close location of the exhaust manifold - removal of the protection may be required.
• 🔍 In diesel versions (for example, CD20) the starter is moved closer to the front of the engine.

To accurately identify a node, refer to thick positive wire (usually red) coming from the battery, and thin control wire (from the ignition switch). The photo below shows a typical location for Sunny B14:

(Note: For clarity, the crankcase protection has been removed in the photo.)

⚠️ Attention: On cars with automatic transmission, access to the starter may be blocked by the torque converter. In this case you will need partially lower the box tray or use a lighted mirror to work blindly.

Step-by-step instructions for removing the starter

The dismantling process takes from 30 minutes to 2 hours, depending on the degree of corrosion of the fasteners and the experience of the technician. Follow the algorithm:

1. Turn off the power: Remove the negative terminal from the battery. If the battery is located in the trunk (as in some versions Sunny N16), use a key extension.
2. Provide access:
   • On front-wheel drive models, simply remove crankcase protection (4 bolts).
   • On all-wheel drive (Sunny 4WD) may require dismantling drive shaft.
3. Disconnect the wires:
   • First remove thin control wire (usually secured with a nut 10 mm).
   • Then unscrew the nut positive wire (key 12 mm) and take it to the side, insulating it with electrical tape.
4. Remove the fastenings:
   • The upper starter bolt is unscrewed with a head 14 mm.
   • The bottom bolt (the most problematic) requires extension and universal joint — it is hidden behind a heat shield.

Remove the starter: Carefully pull the assembly down, turning it counterclockwise to disengage from the flywheel.

When disconnecting the wires, be careful: positive contact often “sticks” to the starter terminal. Don't try to pull it - it's better to process it WD-40 and wait 5-10 minutes. If the terminal still does not move, use pliers with insulated handles, but do not apply excessive force - you may damage the contact pad.

💡

If the lower starter bolt does not come off due to corrosion, try the “heat-cool” method: heat the bolt with a hair dryer (or a blowtorch at a distance), then immediately spray WD-40 and try to unscrew it. This method works in 80% of cases.

Checking the starter after removal: fault diagnosis

Before installing a new starter or repairing an old one, you must check its functionality. To do this, you will need a multimeter and a charged battery (or a 12V power supply). Basic tests:

Type of check	Normal value	Reason for rejection
Solenoid relay coil resistance	0.5–1.0 Ohm	Open circuit or interturn short circuit
Voltage at the control contact (when 12V is supplied)	12V (you should hear a click)	Relay malfunction or open circuit
Current consumption when scrolling (no load)	30–50 A	Worn brushes or bearings
Bendix condition (gear teeth)	No chips or wear	Worn flywheel or bendix

To check the solenoid relay, connect plus from the battery to the relay contact, and minus - to the starter housing. A working relay will emit loud click, and the Bendix gear will move forward. If there is no click, the relay must be replaced. If there is a click, but the gear does not move out, the problem is Bendix drive.

To test the armature, apply voltage directly to the starter (plus to the lower contact of the relay, minus to the housing). A serviceable node will be rotate evenly without extraneous noise. Grinding or jerking sounds indicate:

• 🔧 Wear of bushings (shaft play)
• 🔧 Damage to armature winding
• 🔧 Collector contamination (sparking)

💡

If the starter does not respond to voltage supply, but the solenoid relay works, in 90% of cases the fault is brush assembly or breakage of the armature winding. Repair is possible, but it is often cheaper to buy a new starter (especially for geared models).

Typical mistakes when removing and installing a starter

Even experienced car owners make mistakes that lead to re-dismantling or failure of the new starter. Here are the most common:

1. Ignoring flywheel condition: If the flywheel teeth are worn out, a new Bendix will last a month at most. Check the flywheel for nicks or "bald spots" - Replace it if necessary.
2. Incorrect tightening of fasteners:
   • Weak tightening → vibration and destruction of the starter housing.
   • Over-tightening → stripping threads in the crankcase (especially important for aluminum blocks GA16DE).

Mixed up wires: Connecting a thin control wire to the positive terminal results in short circuit and fuse blown (usually F10 or F15 in the block under the hood).

Lack of lubrication: Bendix and starter shaft must be clean and lubricated (use Litol-24 or Molykote). Without lubrication, the unit will run dry and quickly fail.

Critical error: installing the starter without checking the clearance between the Bendix gear and the flywheel. The optimal gap is 0.5–1.5 mm. If it is less, the starter will “wedge”; if it is more, the bendix will not be able to engage properly.

One more nuance: after installing a new starter be sure to check the voltage at the terminals when starting the engine. If it falls below 9V, the problem may be low battery or oxidized terminals, and not in the starter.

Choosing a new starter: original vs analogues

When purchasing a replacement, pay attention to article number of the original starter and compatibility with your modification Sunny. Below is a correspondence table for popular engines:

Engine model	Original article	Recommended analogues	Average price, rub.
GA14DE (1.4 l)	23300-4M000	Bosch 0001108150, Denso DSR2015	4 500–7 000
GA15DE (1.5 l)	23300-65F00	Valeo 438086, Delphi SS10103	5 000–8 500
GA16DE (1.6 l)	23300-4M010	Mitsubishi SR4501, Hitachi S125-010	6 000–9 500
SR20DE (2.0 L)	23300-40X00	Bosch 0001108155, Denso DSR2020	7 500–12 000

When choosing an analogue, pay attention to:

• 🔧 Starter type: geared or gearless. For Sunny Gearboxes are more often used - they are more compact and more reliable at low temperatures.
• 🔧 Power: for diesel engines (CD20) requires a starter with current 1.4–1.7 kW, for gasoline (GA16DE) enough 0.8–1.2 kW.
• 🔧 Complete set: in some sets (for example, Denso) new mounting bolts and replacement brushes are included.

Avoid cheap, unbranded Chinese starters - they often have weak solenoid relay and quickly fail in cold weather. Optimal price/quality ratio Bosch, Denso And Valeo.

Installation and performance check

Installation of the starter is carried out in reverse order, but there are several key points:

1. Clean before installation seat on the clutch housing from dirt and oil.
2. Tighten the fastening bolts criss-crossto avoid body distortion.
3. Connect first thin control wire, then positive. This will prevent accidental shorting.
4. After connecting the battery, check starter voltage with a multimeter when turning the key - it should be at least 11.5V.

The first start of the engine after replacing the starter must be short (2–3 seconds). If the starter works normally, but the engine does not catch, check:

• 🔧 Fuel pump (should buzz when the ignition is turned on).
• 🔧 Spark plugs (may be filled with gasoline).
• 🔧 Crankshaft position sensor (if there is no spark).

⚠️ Attention: If after installing a new starter you hear metallic clang when starting, stop the engine immediately! This is a sign that the bendix is ​​not disengaging from the flywheel. Causes: faulty retractor relay or incorrect gear travel adjustment.

FAQ: Frequently asked questions about Nissan Sunny starters

Can I repair the starter myself or is it better to buy a new one?

Repair is possible if the problem is brush assembly, solenoid relay or bearings. However, this requires spare parts (for example, a brush repair kit for Sunny costs ~1,500 rubles) and experience working with power tools. If faulty anchor or stator winding - It's cheaper to buy a new starter.

The starter turns, but the engine does not start. What is the reason?

In this case the problem not in the starter. Check:

• 🔋 Battery charge (voltage should be ≥ 12.4V).
• 🔥 Spark on the candles (you can unscrew one spark plug and crank the engine, keeping it grounded).
• ⛽ Fuel pressure (when you turn the key you should hear the sound of the fuel pump running).
• 📊 ECU errors (for example, P0340 — malfunction of the camshaft position sensor).

How often do you need to replace the starter on a Nissan Sunny?

Average starter life - 150–200 thousand km, but it depends on the operating conditions:

• 🚗 In the city (frequent starts) - replacement may be required after 100 thousand km.
• 🏔 In a frosty climate, wear accelerates due to increased load on the battery and starter.
• 🔧 If the generator is faulty (battery is undercharged), the starter works with overload.

Signs of imminent breakdown: slow rotation of the crankshaft, extraneous noise, the need for several attempts to start.

Is it possible to jump-start a Nissan Sunny with a faulty starter?

Yes, but with reservations:

• ✅ On manual transmission - you can if you turn it on 2nd gear and accelerate the car to 10–15 km/h.
• ❌ On automatic transmission - strictly prohibited! This will cause the box to break.
• ⚠️ On Sunny with SR20DE (due to the high compression ratio) push start may damage the catalyst.

Alternative: close the starter directly, supplying 12V to the control contact of the solenoid relay (but this is a temporary solution!).

What oil should I use to lubricate the starter?

Suitable for processing shaft and bendix:

• 🛢 Litol-24 - universal option, can withstand temperatures from -40°C to +120°C.
• 🛢 Molykote BR2 Plus — specialized lubricant for electric motors, reduces brush wear.
• 🛢 Grease for CV joints (For example, Castrol LMX) - if you need to protect the unit from moisture.

Do not use graphite lubricant or WD-40 — they are not intended for high loads and “dry out” over time.
