Starter on Nissan AD (also known as Nissan Cedric or Nissan Gloria depending on the market) is a critical component on which engine starting depends. Its failure is manifested by characteristic clicks without cranking, slow rotation or a complete lack of response to turning the key. However, before replacing or repairing, you need to know exactly where is the starter located on a specific modification AD (Y30, Y31 or Y32) as its position may differ depending on the engine and gearbox type.

In this article you will find not only starter layout diagrams with reference to popular motors (RB20E, RB25DE, TD27 etc.), but also practical advice on dismantling, including typical mistakes, which owners allow for self-repair. We'll also look at how to differentiate between a bad starter and a battery or wiring issue - saving you time and money.

Nissan AD models and their modifications: where to look for a starter

Nissan AD was produced in three generations (Y30, Y31, Y32), and the location of the starter depends on the type of power unit and drive. Below is a brief classification:

  • 🔧 Y30 (1987–1992): Starter on gasoline engines (RB20E, RB20ET) is usually found on the right in the direction of travel (battery side), under the intake manifold. On diesel LD28 - on the left, closer to the checkpoint.
  • 🔧 Y31 (1991–1995): On RB25DE And RB20DE starter is displaced down and forward, partially covered by crankcase protection. On all-wheel drive versions (Attesa E-TS) access is complicated by the transfer case.
  • 🔧 Y32 (1995–1999): Starter on VH41DE (V6) located behind the engine, next to the flywheel. Access requires removal of the heat shield.

It is important to consider that on vehicles with automatic transmission (For example, RE4R01A) the starter can be shifted 5–10 cm forward relative to the mechanical versions. This is due to the design of the torque converter.

Precise starter location on popular engines

To avoid wasting time searching, use the table below. It shows the location of the starter for the most common engines. Nissan AD:

Engine model Fuel type Starter location Access Features
RB20E Gasoline On the right (in the direction of travel), under the intake manifold Removal of air duct and partial protection required
RB25DE Gasoline On the right, closer to the checkpoint, under the generator The air conditioner pipe is in the way (on some versions)
TD27 Diesel On the left, at the base of the checkpoint Dismantling is complicated by the turbine (on turbo versions)
VH41DE Petrol (V6) Behind the engine, next to the flywheel Removal of heat shield and part of subframe required

On diesel versions (TD27, LD28), the starter is often confused with the generator due to its similar appearance, but it is always located lower and closer to the gearbox. If you are not sure, focus on the thick positive wire from the battery - it always goes to the starter.

Step-by-step instructions: how to find the starter on a Nissan AD

If you have never worked with Nissan AD, follow this algorithm. For clarity, let's look at the search using an example RB25DE (Y31):

  1. Open the hood and remove the negative terminal from the battery (key 10). This will prevent short circuit.
  2. Inspect the right side of the engine (in the direction of travel). The starter is located under the generator, next to the gearbox.
  3. Remove the air duct from the air filter to the throttle valve - it blocks the view.
  4. Look for a cylindrical body ~10 cm in diameter with a thick positive wire connected (usually red).
  5. Check the fastening: the starter is fixed with two bolts (14mm head) to the gearbox housing.

Disconnect the battery (negative terminal)

Remove the air duct and protection (if equipped)

Mark the location of the wires (take a photo)

Prepare the tool: 14mm socket, extension, ratchet handle

Clear the area of dirt (especially around the bolts) -->

On diesel AD (For example, TD27) the starter can be hidden under the turbine. In this case, you will need to remove the intercooler or loosen the turbine mount for access.

💡

If the starter “clicks” but does not turn, first check the voltage at its terminals with a multimeter. Often the problem lies in oxidized contacts or a discharged battery, and not in the device itself.

Typical mistakes when searching and dismantling the starter

Even experienced car owners make mistakes that lead to breakdowns or injuries. Here are the most common:

  • ⚡ Ignoring battery disconnection. When working with electricians, this can result in a short circuit or deployment of the airbags (on later versions of the Y32).
  • 🔧 Use of excessive force when unscrewing the bolts. On Nissan AD The starter mounts often stick and need to be pre-treated with WD-40.
  • 🔌 Confusion with wires. The starter has two contacts: a thick positive one (from the battery) and a thin control one (from the ignition switch). They cannot be mixed up when reassembling.
  • 🛠️ Incomplete dismantling. For example, on VH41DE they forget to remove the heat shield, which is why the starter cannot be removed.
⚠️ Attention: On all-wheel drive Nissan AD (with system Attesa E-TS) the starter may be partially covered by the transfer case. Trying to pull it out without removing the protection will damage the wiring!

How to distinguish a starter malfunction from other problems

Before removing the starter, make sure that this is the problem. Symptoms of malfunctions often overlap with other nodes:

Symptom Possible reason How to check
Clicking sound, but the engine does not turn over Faulty solenoid relay or dead battery Ring the relay, measure the voltage on the battery (should be ≥12.4 V)
Starter turns slowly Discharged battery, oxidized terminals or worn starter brushes Check voltage under load (at startup)
Starter does not respond to key Open control circuit, faulty ignition switch or fuse Ring the wire from the lock to the starter, check fuse F10 (10A)

If you hear when you turn the key single click, but the starter does not rotate, with a 90% probability the solenoid relay is to blame. It can be replaced separately without purchasing a complete starter. On Nissan AD The relay often fails due to corrosion of the contacts - just clean them with sandpaper.

How to check the starter without removing it?

Connect the positive battery cable directly to the starter control terminal (thin wire). If it works, the problem is in the control circuit (ignition switch, relay, fuse).

Starter Removal: Tools and Tips

To remove the starter Nissan AD you will need:

  • 🔧 Head 14 (long or with extension)
  • 🔧 Ratchet handle
  • 🔧 Flat blade screwdriver (for disconnecting terminals)
  • 🔧 WD-40 or similar rust remover
  • 🔧 Multimeter (to check voltage)

Dismantling algorithm:

  1. Disconnect negative terminal battery
  2. Remove protective cover (if any) and air duct.
  3. Unscrew positive wire nut (key for 10).
  4. Disconnect control wire (thin, usually with a connector).
  5. Unscrew two mounting bolts starter (head 14).
  6. Carefully pull out the starter down and forward (on Y31 you may need to turn counterclockwise).
⚠️ Attention: On diesel Nissan AD (TD27) the starter weighs more due to the reinforced gearbox. Do not drop it - this may damage the Bendix gear!
💡

Before installing a new starter, be sure to clean the seat on the gearbox from dirt and old lubricant residues. This will prevent misalignment and premature wear.

FAQ: Frequently asked questions about the Nissan AD starter

Can the starter be repaired or is it just a replacement?

Most starters Nissan AD subject to repair. Most often, replacement is required:

  • Brushes and bushings (wear out at 150–200 thousand km).
  • Solenoid relay (problems with contacts).
  • Bendix (wear of gear teeth).

The cost of repairs is 2–3 times lower than purchasing a new starter (the price of the original is from 15,000 ₽).

Which starter is suitable to replace the original?

For Nissan AD analogues are suitable:

  • Denso (article 28000-4M000 for RB-series).
  • Mitsuba (article M000T27301 for diesel engines).
  • Bosch (universal models with gearbox).

When choosing, pay attention to number of bendix teeth (there are 10 of them on Y32, 9 on Y30).

What to do if the starter turns, but the engine does not start?

The problem is not in the starter, but in:

  • Ignition system (check spark plugs, coils, distributor on Y30).
  • Fuel system (pump, filter, injectors).
  • Crankshaft position sensor (CKP).

On RB25DE a common cause is a malfunction camshaft sensor (CMP).

How long does it take to replace a starter?

Time depends on model:

  • Y30 (RB20E): 1–1.5 hours (easy access).
  • Y31 (RB25DE): 2–3 hours (generator and air conditioner interfere).
  • Y32 (VH41DE): 3–4 hours (subframe removal required).

The service station charges from 3,000 to 8,000 rubles for the work, depending on the complexity.
