Drive belt Nissan Almera Classic (also known as N16 in the B10 body) is a critical element on which the operation of the generator, power steering (if installed) and air conditioning depends. If it breaks or slips, it can lead to battery discharge, engine overheating, or loss of control while driving. Despite its apparent simplicity, replacing a belt requires knowledge of the nuances: from the correct selection of spare parts to precise tension adjustment.
In this article we will analyze not only the standard replacement procedure, but also common mistakes, which owners allow for self-repair. For example, why a new belt can whistle after only 100 km, how to avoid misalignment of the rollers, and what to do if play appears in the steering after replacement. You will also find current article numbers for belts and rollers for various modifications Almera Classic (including versions with air conditioning and power steering).
Signs of a worn drive belt: when is it time to change it?
The manufacturer recommends checking the condition of the belt every 15,000 km, and replacement should be carried out through 60,000–80,000 km (or every 4-5 years, even if the mileage is low). However, the actual service life depends on operating conditions: in hot climates or with frequent off-road trips, the belt wears out 1.5–2 times faster. Here are the key signs that it's time to act:
- 🔊 Whistle from under the hood when starting the engine or when the load increases (turning on the air conditioner, headlights). More often appears in damp weather.
- 🔧 Cracks or delamination on the surface of the belt (visible upon visual inspection). Even small transverse cracks are a reason for replacement.
- 🚗 Belt slippage, which causes the headlights to dim, the battery charge to drop, or the power steering to fail.
- 🔄 Uneven wear (one side of the belt wears out faster than the other) is a sign of misalignment of the pulleys or rollers.
Particular attention should be paid to the belt if there are noticeable traces of oil or coolant - this means a leak from the seals or pump. In this case, it is not enough to simply replace the belt: you need to eliminate the cause of the contamination, otherwise the new belt will not last more than a month.
⚠️ Attention: If the belt breaks on the way, do not try to drive to the service station “on the battery”. Without charging the generator electronics Almera Classic may display errors, and if the battery is low, may block the steering column (on versions with ESD).
Selection of spare parts: original vs analogues
For Nissan Almera Classic (N16) with engines QG15DE (1.5 l) and QG18DE (1.8 L) fits the following belt sizes:
| Modification | Belt length(mm) | Original article number | Popular analogues |
|---|---|---|---|
| Without air conditioning and power steering | 940 (6PK940) | 11720-4M000 |
Gates 6PK940, Contitech 6PK940, Dayco 6PK940 |
| With air conditioning (without power steering) | 1115 (6PK1115) | 11720-4M001 |
Gates 6PK1115, Bosch 1 987 949 664 |
| With power steering and air conditioning | 1225 (6PK1225) | 11720-4M005 |
Dayco 6PK1225, SKF VKM 30122 |
When choosing an analogue, pay attention to number of edges (6PK) And material. Belts Gates And Contitech are considered the most durable, but fakes are common. Check the packaging for the presence of a hologram and barcode. It is also recommended to replace tension roller (original article number - 11950-4M000), since its wear accelerates the destruction of the belt.

If you buy a belt in an online store, check with the seller if it is suitable for your modification Almera Classic. For example, belts for versions with QG18DE and air conditioning are often confused with belts for Nissan Primera P12, which are similar in appearance, but have a different geometry.
Tools and preparation for replacement
To work you will need:
- 🔧 A set of sockets and a “14” wrench (for the tension roller).
- 🔧 Key for “10” or “12” (for attaching the generator).
- 🔧 Puller for the crankshaft pulley (if replacement of rollers is required).
- 🔧 Torque wrench (for precise tightening).
- 📏 Ruler or special gauge for checking tension.
Before starting work:
Disconnect the battery (negative terminal first)|
Place the car on a level surface and secure the rear wheels|
Remove the right front wheel and fender liner (to access the crankshaft pulley)|
Prepare a flashlight - lighting under the hood Almera Classic leaves much to be desired|-->
If you are changing the belt for the first time, take a photo of its routing diagram on your phone. On Almera Classic With air conditioning, the belt goes around 4-5 pulleys, and it’s easy to get tangled when reassembling. Also check the condition of all rollers: if they play or make noise when rotating, they need to be replaced.
To avoid losing the crankshaft pulley key when removing, wrap it in advance with electrical tape or secure it with plasticine.
Step-by-step instructions for replacing the belt
The replacement process differs depending on the configuration. Below are instructions for the most common version - with air conditioning and power steering.
- Release the belt tension. To do this, use a “14” key to turn the tension roller counterclockwise (on some modifications you need to loosen the generator mounting bolt).
- Remove the old belt. Carefully pull it off the pulleys, remembering the trajectory. If the belt is stuck, do not pull by force - treat the pulleys with WD-40.
- Check pulleys and rollers. They should rotate without play or extraneous sounds. If any defects are found, replace them.
- Install a new belt. Start with the crankshaft pulley, then run the belt over the alternator, air conditioning, and power steering pulleys (if equipped). The last one should be the tension roller.
- Adjust the tension. For Almera Classic normal sagging of the belt between the generator and crankshaft pulleys - 8–10 mm when pressed with a force of 10 kg. Use a dynamometer or check by eye, comparing with a new belt.
After installation, start the engine and check the operation of all systems: battery charging (should be 13.8–14.4 V at idle), absence of whistling and uniform rotation of the pulleys. If the belt slips, increase the tension slightly.
⚠️ Attention: On versions with QG18DE and the air conditioner, the belt may touch the guard. This is normal, but if it rubs too much, add a piece of rubber or plastic.
Common mistakes and how to avoid them
Even experienced car owners make mistakes when replacing a belt. Almera Classic. Here are the most common of them:
- 🔧 Pulling the belt. This leads to premature wear of the generator bearings and rollers. The symptom is a hum when the engine is running.
- 🔄 Wrong trajectory. For example, if a belt is twisted 180°, it will wear 2-3 times faster.
- 🛑 Ignoring videos. A worn tension pulley can jam and tear the new belt.
- 🔥 Dirt ingress. Dust and sand on the pulleys act as an abrasive, shortening the life of the belt.
To avoid problems, after replacing, drive 5–10 km and check the tension again. On Almera Classic The belt may “settle” during the first hours of operation and will have to be tightened.
What to do if the belt whistles after replacement?
The whistling sound of a new belt is normal in the first 100–200 km, while it is “grinding in.” But if the sound does not pass through, check:
1. Tension (most often the reason is weak tension).
2. Condition of the pulleys (contamination or corrosion).
3. Belt quality (counterfeits often whistle due to low-quality rubber).
If the whistle only appears when the air conditioner is turned on, the problem may be a weak alternator or a faulty compressor.
Cost of service replacement vs self-repair
In official services Nissan for replacing the drive belt Almera Classic take from 1,500 to 3,000 rubles (excluding the cost of spare parts). In private car services the price is lower - 800–1,500 rubles. However, if rollers or pulleys need to be replaced, the amount may increase to 5,000–7,000 rubles.
If you replace it yourself, you will only spend money on spare parts:
- 💰 Belt - from 500 to 1,500 rubles (depending on the brand).
- 💰 Tension roller - from 800 to 2,000 rubles.
- 💰 Deflection roller (if required) - from 600 rubles.
The savings are obvious, but remember: if you make a mistake (for example, tightening a belt), the repair will cost more. If you are not confident in your abilities, it is better to entrust the work to professionals.
Replacing the drive belt yourself Almera Classic justified if you have experience working with cars and the necessary tools. Otherwise, the risk of error (and additional costs) outweighs the savings.
FAQ: Frequently asked questions about replacing the belt on a Nissan Almera Classic
Is it possible to drive with a squealing belt?
In the short term, yes, but it is fraught with consequences. The whistle means that the belt is slipping, which means that the alternator is not charging the battery, and the power steering and air conditioning are working intermittently. In the long term, this will lead to battery discharge, engine overheating (due to weak pump operation) and pulley wear.
Which belt is better - original or Gates?
Original belts Nissan manufactured by the same manufacturers (most often Mitsuboshi), which is Gates or Contitech, but are more expensive due to the logo. There is no difference in reliability, so you can safely take analogues. The main thing is to avoid fakes (check the hologram and barcode).
Do I need to change the belt if it looks intact, but the mileage is already 80,000 km?
Yes, it is necessary. The rubber of the belt loses its elasticity over time, even without visible cracks. Such a belt can break at any time, especially in cold weather or under high load (for example, when towing). For Almera Classic The age of the belt is critical: if it is more than 5 years old, replace it regardless of the mileage.
What happens if the belt breaks while driving?
The consequences depend on the configuration:
- On versions without power steering - the generator will fail, the battery will be discharged, the engine will stall.
- On versions with power steering — it will additionally become difficult to turn the steering wheel (especially dangerous at speed).
- On versions with air conditioning - the compressor may jam, which will lead to belt breakage and damage to the pulleys.
If the belt breaks, immediately pull over to the side of the road and turn off the engine. Driving on battery power is only allowed to the nearest service station (no more than 5–10 km).
Can I use a belt from another Nissan model?
Sometimes it is possible, but with reservations. For example, a belt from Nissan Primera P12 (1.8 l) suitable for Almera Classic with QG18DE, but only if it has the same equipment (with air conditioning and power steering). However, the length and number of ribs must match exactly. It’s better not to experiment and take a belt according to the article number for your modification.
