Starter on Nissan Terrano: where it is, how to get there and remove it

The starter is one of the key components in the engine starting system Nissan Terrano, and its failure can immobilize the car at the most inopportune moment. Owners of this model often encounter difficulties in finding parts: depending on the year of manufacture and modification (for example, Terrano R51 or Terrano II R20) starter location may vary. Moreover, access to it is complicated by mounted units and suspension elements, which requires knowledge of exact landmarks.

In this article we will analyze in detail where exactly the starter is installed on different versions Nissan Terrano, we will provide visual diagrams and photographs indicating fastenings, and also give practical advice on dismantling. We will pay special attention to nuances that are not described in standard manuals - for example, how to avoid damaging the wiring harness during removal or what tools are needed for working in cramped conditions.

Design and role of the starter in Nissan Terrano

Starter Nissan Terrano is an electromechanical device that converts the electrical energy of the battery into the mechanical force necessary to crank the engine crankshaft. Its design is based on four key elements:

• 🔋 DC motor - creates a torque.
• 🔄 Bendix (overrunning clutch) — engages with the flywheel and prevents kickback.
• 🧲 Solenoid relay — pushes out the bendix and closes the power circuit.
• 🔌 Brush unit — transmits current to the rotor.

On Terrano Two types of starters were installed: geared (more compact and reliable) and gearless (simpler in design, but less durable). The former are more common on models after 2010, the latter - on earlier versions. The type can be determined by its appearance: gearboxes have an additional plastic housing on the front.

It is important to understand that a starter malfunction can manifest itself in different ways: from a complete lack of response to turning the key to a characteristic click of the retractor relay without spinning the flywheel. In 60% of cases the problem lies in brush wear or burning of relay contacts, which requires diagnostics before replacing the entire assembly.

Where is the starter located on Nissan Terrano R51 (2005–2015)

On the most common version Nissan Terrano R51 (with diesel engines YD25DDTi and gasoline QR25DE) the starter is located at the bottom of the engine, on the side gearboxes. More precisely, under the intake manifold, closer to the oil filter. Access to it is complicated by the following elements:

• 🔧 Protective cover (not present on all modifications).
• 🔗 Air conditioning pipes (on models with climate control).
• ⚙️ Engine mount bracket (may require partial dismantling).

To accurately identify a location, focus on two key visual markers:

1. To the left of the starter (in the direction of travel) is oil filter (cylindrical black or blue body).
2. Right - gearbox housing with a characteristic ribbed aluminum coating.

The photos below show the starter on Terrano R51 with diesel engine YD25 (view from below the car):

The image shows the starter (highlighted in red circle), located between the oil filter and the gearbox. Two thick wires approach it: red (positive) and black (control from the ignition switch).

A critical nuance: on diesel versions, the starter is shifted 3–5 cm to the left relative to gasoline versions, which requires a different approach when dismantling.

Starter location on Nissan Terrano II R20 (1993–2006)

On earlier models Nissan Terrano II (R20) The starter is installed slightly differently. Here he is higher, closer to the top of the engine, and partially closed intake manifold. This makes access difficult, especially on engines TD27 (diesel) and KA24E (gasoline).

Main differences from R51:

Parameter	Terrano R51 (2005–2015)	Terrano II R20 (1993–2006)
Location	Lower part, 近 gearbox	Upper part, under the intake manifold
Access	From below (requires a lift or pit)	From above (removal possible without pit)
Fastening	2 M12 bolts	3 M10 bolts (on diesels)
Difficulty in dismantling	Medium (air conditioning pipes interfere)	High (manifold removal required)

On Terrano II with gasoline engine KA24E the starter can be found when viewed from the battery side: it is located under throttle cable and is partially covered with a heat shield. On diesel TD27 access is even more difficult - you have to remove it inlet pipe and move the fuel equipment wiring harness to the side.

⚠️ Attention: On Terrano II R20 with a diesel engine, when dismantling the starter, be sure to turn off high pressure fuel pump (HPF)to prevent air from entering the system. Otherwise, after assembly, the engine will not start without bleeding.

Step-by-step instructions: how to get to the starter

The process for accessing the starter depends on the model Terrano, but the general sequence of actions is as follows. To work you will need:

• 🔧 Set of sockets (10, 12, 14 mm) and extension.
• 🔨 Ratchet wrench or wrench.
• 🔌 Flat blade screwdriver (for disconnecting terminals).
• 📸 Phone or flashlight (for illuminating hard-to-reach places).

For Terrano R51 (bottom):

1. Remove crankcase protection (6 bolts around the perimeter).

2. Disconnect starter terminals: first the control wire (thin, usually black), then the power wire (thick red). Use a screwdriver to carefully release the latches.

3. Unscrew two mounting bolts (14 mm head). The top bolt can be hidden under the wiring harness - it is more convenient to unscrew it using an extension cord.

4. Carefully pull the starter down, turning it counterclockwise to avoid snagging the oil filter.

For Terrano II R20 (top):

1. Remove decorative engine cover (4 plastic clips).

2. Disconnect inlet pipe (on diesel engines) or throttle cable (on petrol models).

3. Unscrew heat shield (3 bolts per 10 mm).

4. Disconnect the terminals and unscrew the fastening bolts (there are three on diesel engines, two on gasoline engines).

⚠️ Attention: On Terrano II R20 with diesel engine TD27 When reassembling, be sure to check the gap between the starter and the flywheel. It should be 0.3–0.5 mm. If the gap is smaller, the bendix will jam, which will lead to rapid wear.

Typical mistakes when searching and removing the starter

Even experienced car owners make mistakes that can lead to damage to the starter or neighboring components. Here are the most common ones:

• ⚡ Ignoring battery disconnection. When working with electrical contacts, this may cause a short circuit or blown fuse F10 (responsible for the starter circuit).
• 🔧 Use of excessive force when unscrewing the bolts. On Terrano The starter mounts often stick, but using an impact tool can damage the threads in the cylinder block.
• 🔌 Terminal mix-up when connecting back. If the control and power wires are swapped, the starter will constantly rotate, which will lead to overheating.
• 🛠️ Bendix not checked before installing a new starter. In 20% of cases, the problem lies in the wear of the flywheel teeth, and not in the starter itself.

Another common mistake is trying to dismantle the starter without removing engine mount bracket (on R51). This may cause deformation of the starter housing or damage to the crankshaft position sensor wire. If you feel that the starter is “pinned”, do not pull it by force - check if the bracket is in the way.

On diesel Terrano people often forget about gasket between starter and cylinder block. Its absence will lead to air leaks and unstable engine operation. When purchasing a new starter, make sure that the kit includes a gasket, or purchase it separately (part number for R51: 24410-4M000).

How to check the starter without removing it from the car

Before dismantling the starter, you should make sure that it is the problem. Here are three ways to diagnose without removal:

1. Checking the solenoid relay:

   • Turn the key to the ignition position.
   • If you hear a clear click, but the starter does not rotate, the problem is retractor or brush assembly.
   • If there is no click, check fuse F10 (10A) and starter relay (located in the fuse box under the hood).

2. Power check:

   • Connect a voltmeter to the starter power terminal (thick red wire).
   • When you turn the key, the voltage should be not less than 11.5 V. If less, the problem is in the battery or power cable.

3. Bendix check:

   • Engage 4th gear and push the car forward.
   • If the starter rotates (a characteristic noise is heard), but the engine does not start, it is faulty bendix.

If the starter rotates, but the engine does not “catch”, the problem may lie in:

• 🔋 Discharged battery (voltage below 11 V).
• 🔧 Wear of flywheel teeth (checked visually through the inspection window in the bell box).
• 🔌 Oxidation of contacts on the battery or mass wire.

Tips for choosing a new starter

When purchasing a starter for Nissan Terrano pay attention to the following parameters:

Parameter	Terrano R51 (2005–2015)	Terrano II R20 (1993–2006)
Type	Gearbox (Mitsubishi SR42)	Gearless (Bosch 0001108150)
Rated voltage	12 V	12 V (on diesel engines 24 V for starting heating)
Power	1.4–1.7 kW	1.1–1.4 kW
Manufacturer OEM	Mitsubishi, Denso	Bosch, Valeo
Average price, rub.	8 000–12 000	6 000–9 000

When choosing, pay attention to:

• 🔍 VIN compatibility. Check with the seller, as starters for gasoline and diesel versions are different.
• 🔧 Complete set. The kit must contain mounting bolts and a gasket.
• 📄 Guarantee. The minimum period is 12 months.

From trusted manufacturers for Terrano we recommend:

• Denso - original quality, but high price.
• Bosch — optimal price/quality ratio.
• Valeo - a budget option for older models.

⚠️ Attention: There are often fake starters on the market under the brand Denso. The original part has a logo engraved on the case and a holographic sticker. Counterfeits are usually 200–300 grams lighter due to the use of low-quality materials.

Frequently Asked Questions

Is it possible to start a Nissan Terrano with a faulty starter?

Yes, but only if the problem is in the electrical part (for example, the solenoid relay burns out). To do this:

1. Engage 2nd gear.
2. Turn the key to the ignition position.
3. Push the vehicle (needs 1-2 people to help) or tow it.
4. After accelerating to 10–15 km/h, sharply release the clutch and the engine should start.

⚠️ This method does not work if the bendix is faulty or the flywheel teeth are worn out.

How long does it take to replace a starter on a Terrano?

On Terrano R51 with a lift or pit - 1.5–2 hours. On Terrano II R20 (especially diesel) - up to 3–4 hours due to the need to remove the intake manifold. Without experience, it will take 1.5–2 times more time.

What tools are needed to replace the starter?

Minimum set:

• Heads for 10, 12, 14 mm + extension.
• Ratchet wrench.
• Flat blade screwdriver.
• Torque wrench (for tightening bolts with a torque of 25–30 Nm).
• WD-40 or similar penetrating lubricant (for loosening stuck bolts).

What should I do if the engine does not start after replacing the starter?

Check:

1. The terminals are connected correctly (the control wire must be connected to the solenoid relay).
2. Battery voltage (at least 12.5 V).
3. Fuse status F10 (10A) in the block under the hood.
4. The gap between the bendix and the flywheel (should be 0.3–0.5 mm).

If the problem persists, the wiring harness may be damaged or the ignition switch may be faulty.

Can I repair the Terrano starter myself?

Yes, if the problem is:

• Worn brushes (replacement will cost 500–800 rubles).
• A burnt solenoid relay (the cost of a new one is 1,500–2,000 rubles).
• Contaminated contacts (clean with alcohol or a file).

The situation is more complicated when replacing a bendix or rotor - this requires a press and experience working with electric motors. In such cases, it is cheaper to buy a new starter.
