Nissan Almera G15 is a popular sedan that is valued for its reliability and unpretentiousness. However, even such machines have weak points, and one of them is drive belt (especially if the car is equipped with air conditioning). This element is responsible for transmitting torque from the crankshaft to attachments: generator, air conditioning compressor, power steering pump (if equipped) and pump. Belt wear leads to slipping, whistling, and in critical cases, to breakage and failure of vehicle systems.
Owners Almera G15 are often faced with the question: which belt to choose, how to replace it correctly and what to look for when buying? In this article we will look at articles of original and analog belts, we'll tell you about signs of wear, give step-by-step instructions for replacement, and share tips for extending service life. We will pay special attention to the nuances associated with the presence of an air conditioner - this is important, since the length and configuration of the belt in this configuration differ from the basic one.

If you are not sure about the choice, use online spare parts catalogs such as Exist.ru, Autodoc or Nissan Original Parts. Enter the VIN of your car, and the system will select the exact part number. You can also measure an old belt - to do this, use a sewing centimeter or a ruler, but remember that the length is indicated according to outer contour (not along the inner radius!).
Signs of drive belt wear: when is it time to change?
The drive belt is a consumable that requires regular inspection. The manufacturer recommends replacement every 60–80 thousand km, but in practice the service life depends on operating conditions. Here are the key signs that it's time to change the belt:
- 🔊 Whistling or squeaking when starting the engine or when the load increases (for example, when turning on the air conditioner). This indicates slippage due to insufficient tension or wear.
- 🔍 Cracks, delamination or abrasions on the surface of the belt. Inspect it with the engine off - if cord fibers are visible, replacement cannot be delayed.
- 🚗 Vibration or jerking attachments (generator, air conditioning compressor). This may be due to uneven belt wear.
- ⚡ Voltage drop in the on-board network (dim headlights, electronics failures). The reason is belt slippage and insufficient generator operation.
- ❄️ The air conditioner blows warm air or works intermittently. This may indicate that the belt is slipping on the compressor pulley.
⚠️ Attention: if traces of oil or coolant are visible on the belt, this is a signal about leakage in 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 quickly fail.
To check the condition of the belt yourself, open the hood and visually inspect it along its entire length. Please note:
- 🔎 Depth of cracks - if they penetrate to the cord, the belt must be replaced.
- 📏 Stretching - if the belt sags by more than 10 mm when pressed with a finger, it needs to be tightened or replaced.
- 🔄 Tooth wear (if the belt is toothed) - smoothed or missing teeth lead to slippage.
- Every 10 thousand km
- Every 20 thousand km
- Only when a whistle appears
- Never checked
Step-by-step instructions for replacing the drive belt with Nissan Almera G15
Replacing the drive belt with Almera G15 with air conditioning is a task of medium difficulty. If you have the tools and minimal experience, you can do it yourself. You will need:
- 🔧 A set of keys and sockets (especially for
10,12,14). - 🔩 Torque wrench (for proper tightening of bolts).
- 🔧 Special key for the tensioner (or a suitable lever).
- 📏 Ruler or caliper to check tension.
- 🔦 Flashlight for illuminating hard-to-reach places.
If you decide to change the belt yourself, follow these instructions:
- Preparation: Turn off the engine, disconnect the negative terminal of the battery and remove the right front wheel (this will make it easier to access the tensioner).
- Loosening the tensioner: using the key on
14Turn the tension pulley bolt counterclockwise to loosen the belt. Some modifications may require removal of the engine protection. - Removing the old belt: carefully remove the belt from the pulleys, remembering or photographing its location diagram. On Almera G15 with air conditioning, the belt goes around the pulleys in the following order: crankshaft → generator → air conditioning compressor → pump → tension roller.
- Installing a new belt: Place the belt on the pulleys according to the diagram, starting with the crankshaft. Make sure it lies flat and without distortion.
- Belt tension: use the tensioner to adjust the tension. The optimal deflection of the belt when pressed with a finger should be 8–10 mm. An overtightened belt will shorten the life of the bearings, and an undertightened belt will slip.
- Check: start the engine and check the operation of all systems (generator, air conditioning, power steering). When installed correctly there should be no whistling or vibration.

⚠️ Attention: If, when replacing the belt, you notice play in the tension roller or pulleys, they also need to be replaced. Worn rollers can cause the new belt to wear out prematurely.
If you are not confident in your abilities, it is better to contact the service. Belt replacement cost Almera G15 in a car service is 1500–2500 rubles (excluding the cost of spare parts). However, replacing it yourself will save money and give you confidence in the quality of the work done.
The nuances of replacing a belt with Almera G15 with air conditioning
On vehicles with air conditioning, the belt replacement process has several features:
- Additional compressor pulley: The belt wraps around the air conditioning compressor pulley, which increases its length compared to the basic version without air conditioning. This means that the belts from modifications without air conditioning won't fit!
- Tensioner: on some versions Almera G15 An automatic tensioner is used that does not require manual adjustment. However, it also needs to be checked for wear.
- Access: For ease of replacement, it may be necessary to remove the right fender liner or engine protection. It depends on the year of manufacture and configuration.
Another important point - condition of pulleys. If they are scored, rusted or unevenly worn, this will cause the new belt to wear out faster. If necessary, the pulleys can be cleaned with fine sandpaper or replaced.
What happens if you install a belt of the wrong length?
If the belt is shorter than required, it will not be able to be tensioned without risking damage to the rollers. If it is longer, it will slip, whistle and wear out quickly. In both cases, this will lead to failure of the generator, pump or air conditioning compressor.
How to extend the life of a drive belt?
The service life of the drive belt depends not only on the quality of the part itself, but also on operating conditions. Here are some tips to help increase its resource:
- 🔧 Regular tension check: Even a new belt can stretch over time. Check tension every 10–15 thousand km.
- 🚿 Cleanliness of the engine compartment: If oil, antifreeze or dirt gets on the belt, it will wear out faster. Make sure seals and hoses are tight.
- 🌡️ Avoid overheating: Long-term engine operation at high speeds (for example, in traffic jams in summer) increases the load on the belt. Try not to overload the air conditioner.
- 🔄 Check out the videos: Worn tension or idler rollers create additional resistance, which leads to premature belt wear.
It is also worth paying attention to quality of spare parts. Cheap belts from unknown manufacturers are often made of low-quality rubber, which cracks and crumbles after 20–30 thousand km. It is better to overpay for proven brands, such as Gates, Contitech or Bando.
If you often drive off-road or in high humidity conditions, treat the belt with a special silicone lubricant (for example, CRC Belt Dressing). This will protect it from cracking and extend its service life.
Common mistakes when replacing a belt and how to avoid them
Even experienced car owners sometimes make mistakes when replacing the drive belt. Here are the most common of them:
- ❌ Incorrect tension: too weak leads to slippage, too strong leads to bearing wear. Use a torque wrench or watch the belt deflection.
- ❌ Distortions during installation: If the belt lies crooked on the pulleys, it will wear unevenly. Always check its position after installation.
- ❌ Ignoring videos: Many people forget to check the condition of the tension and idler rollers. Worn rollers can jam and break the new belt.
- ❌ Dirt entry: If sand or oil marks get on the belt during installation, this will shorten its service life. Work in clean conditions.
To avoid these mistakes, follow the manufacturer's instructions and take your time. If you are not sure of your actions, it is better to contact a specialist. Please remember that an incorrectly installed belt can cause break on the move, which can lead to failure of the generator, pump, or even bending of the valves (in rare cases).
The most common cause of premature belt wear is a faulty tensioner. If after replacement the belt starts to whistle again after a short time, first check the tension pulley!
FAQ: Frequently asked questions about the drive belt Nissan Almera G15
Is it possible to drive with a squealing belt?
A short-term whistle during a cold start or high humidity is not critical, but if it is constant, it is a sign of wear or weak tension. Driving for a long time with a whistling belt leads to slipping, insufficient battery charging and engine overheating (due to weak pump operation). It is recommended to eliminate the cause as soon as possible.
Which belt is better - original or analogue?
Original belts Nissan (11720-4M005) are guaranteed to fit in size and quality, but are more expensive. Analogues from Gates or Contitech often not inferior in reliability, but cheaper. The main thing is to buy from trusted suppliers to avoid counterfeits. If your budget allows, it is better to take the original or a premium analogue.
Do I need to change the rollers along with the belt?
This is not required, but is highly recommended. The rollers wear out at about the same rate as the belt. If they have play, noise or signs of wear, it is better to replace them at the same time as the belt. The cost of the rollers is low (from 500 rubles per piece), and replacing them will save you time and money in the future.
What to do if the belt breaks on the road?
If the belt breaks, further movement is only possible to the nearest service center or spare parts store. Without a belt, the generator (the battery will quickly discharge), the pump (the engine will overheat) and the air conditioner will not work. If a gust occurs on the way:
- Stop and turn off the engine.
- Check if any of the pulleys (generator, pump, compressor) are jammed.
- If you have a spare belt and tools, replace it on site.
- If not, call a tow truck or drive with a tow/minimum load (turn off all electrical consumers).
Can I install a belt from another Nissan model?
Theoretically, it is possible if the length, profile and configuration of the pulleys match. For example, belts from Nissan Note or Nissan Micra sometimes they do, but it's risky. It is better to use a belt designed specifically for Almera G15 with air conditioning. Otherwise, problems with tension or slippage may occur.
