Drive belt in Nissan Murano - This is a critical element on which the operation of the generator, air conditioning, power steering and other auxiliary units depends. Despite the simplicity of the design, its breakage or slipping can immobilize the car at the most inopportune moment. Crossover owners Z50 (2003–2007), Z51 (2008–2014) and Z52 (2015–2021) often experience premature belt wear due to high loads on engines VQ35DE And VQ25DD, especially when operating in urban areas or extreme temperatures.
In this article we will look at how to determine belt wear by external signs, which original and similar spare parts are suitable for different generations Murano, and we will also give step-by-step instructions for replacement, taking into account the nuances of the design. We will pay special attention to typical mistakes that even experienced car owners make, and we will tell you why saving on the quality of the belt can result in repairs costing thousands of rubles.
Signs of a worn drive belt: when to sound the alarm
The first symptoms of a belt problem are often ignored until a break occurs. However, there are a number indirect and direct signs, which signal the need for verification:
- 🔊 Whistling or squeaking from under the hood when starting the engine or when suddenly pressing the gas. Particularly noticeable in damp weather or at low temperatures.
- 💡 Battery indicator blinks on the dashboard - a sign of belt slipping and undercharging of the generator.
- 🔧 Cracks, delaminations, or shiny areas on the inside of the belt (visible upon visual inspection).
- 🚗 Increased play when you press the belt with your hand (the norm is deflection no more than
10–15 mmunder load10 kg).
If you notice any of these symptoms, do not delay diagnosis. For example, belt whistling on a cold engine Nissan Murano Z51 with motor VQ35DE in 80% of cases it is associated with rubber wear or oil getting on the surface. You can check this with a flashlight - inspect the belt for greasy stains or burrs.
⚠️ Attention: If the belt begins to “dust” (leaves a black coating on the pulleys), this means that its service life is running out. In this case, replacement is required within 1–2 weeks, otherwise the risk of breakage increases 3 times.
Original articles and analogues: what to choose for Murano
For every generation Murano the manufacturer recommends its original belts, but there are high-quality analogues on the market that often exceed them in terms of service life. Below is the compatibility table for popular engines:
| Generation | Engine | Original article | Recommended analogues | Length (mm) |
|---|---|---|---|---|
| Z50 (2003–2007) | VQ35DE |
11720-9M000 |
Gates K060875, Contitech 6PK2135, Dayco 6PK2138 |
2135 |
| Z51 (2008–2014) | VQ35DE |
11720-9M00A |
Gates K060875HD, Bando 6PK2137, Mitsuboshi 6PK2135 |
2137 |
| Z52 (2015–2021) | VQ25DD (hybrid) |
11720-4M00A |
Gates K080870, Contitech 6PK2510, Optibelt 6PK2510 |
2510 |
When choosing an analogue, pay attention to:
- 🔹 Number of ribs - for Murano it's always
6PK(6 streams). - 🔹 Material - optimal EPDM (ethylene propylene rubber), which is resistant to high temperatures and oil.
- 🔹 Availability of amplifiers - belts with aramid fiber cord (for example, Gates Micro-V) last 30–40% longer.
⚠️ Attention: On Murano Z52 with hybrid installationVQ25DDa belt with an increased resource is used - its replacement is required less frequently (every120–150 thousand km), but the cost of the original is 40–50% higher. Saving on cheap analogues is unjustified here!

Step-by-step replacement instructions: nuances for Murano
Replacing the drive belt with Nissan Murano does not require a special tool, but there are several critical momentsthat distinguish this model from other crossovers Nissan:
- Removing the engine protection. On Z51 And Z52 To access the tensioner you will have to remove the lower plastic protection (4 bolts
10 mm). - Fixing the tensioner. Use the key on
14 mmto loosen the tension roller bolt (on Z50 - key to15 mm). - Correct installation. The belt must go along the pulleys in strict sequence: generator → air conditioning compressor → power steering pump → crankshaft.
For clarity, we present a diagram of the belt route for Murano Z51 with engine VQ35DE:

☑️ Preparing to replace the belt
After installing the new belt be sure to adjust the tension. To do this:
- Tension the belt by turning the tension roller counterclockwise.
- Tighten the roller bolt to torque
40–45 Nm. - Check the deflection: when pressed in the middle between the generator and crankshaft pulleys, it should be
8–10 mm.
If the belt continues to whistle after replacement, check the alignment of the pulleys. On Murano Z50 The bearing of the power steering pump often wears out - its jamming can lead to a broken belt.
Typical mistakes when replacing: how not to damage the car
Even experienced craftsmen sometimes make mistakes that shorten the service life of the belt or damage auxiliary units. Here are the most common:
- 🔧 Belt tightening. Excessive tension leads to premature wear of the generator and power steering pump bearings. On Murano This is manifested by a hum when the engine is running.
- 🛠️ Ignoring the state of the rollers. If the tension or idler roller has play, the new belt will not last longer.
10–15 thousand km. - 🔄 Incorrect installation sequence. For example, if the belt is twisted on the air conditioning compressor pulley, this will cause it to slip and lose refrigerant.
- 🧴 Oil or antifreeze ingress. Even a small amount of technical fluids on the belt reduces its adhesion to the pulleys by 2 times.
On Nissan Murano Z51 with mileage over 150 thousand km The crankshaft pulley often wears out - its beating leads to “eating” of the edges of the belt. Check the pulley for radial runout (tolerance - no more than 0.5 mm).
What happens if the belt breaks?
If the drive belt breaks while driving:
- The generator will turn off → the battery will be discharged (the car will stall in 10–30 minutes).
- The power steering will stop working → the steering wheel will become “stiff”.
- The air conditioning compressor will turn off (not critical, but unpleasant in the heat).
- On models with a hybrid installation (Z52) errors are possible in the energy recovery system.
Replacement timing: when to change the belt according to regulations and facts
The manufacturer recommends replacing the drive belt every 60–90 thousand km or once every 4–5 years, whichever comes first. However, the actual service life depends on operating conditions:
| Operating conditions | Belt service life (thousand km) | Notes |
|---|---|---|
| Urban cycle (frequent starts/stops) | 40–60 | High loads on generator and air conditioner |
| Off-road driving (dust, dirt) | 50–70 | Abrasive wear from sand ingress |
| Extreme temperatures (-30° to +40°) | 35–50 | Rubber loses elasticity |
| Quiet highway driving | 80–100 | Optimal conditions for the belt |
In practice, owners Murano change the belt more often - every 50–70 thousand km, especially if the car is operated in a large city. The fact is that frequent activation of the air conditioner and electric power steering (EPS on Z52) increase the load on the belt by 1.5–2 times.
On Nissan Murano with engine VQ35DE the belt wears out faster than VQ25DD, due to the greater torque and weight of the auxiliary units.
Cost of work: how much does it cost to replace it in the service and independently?
The cost of replacing a drive belt varies depending on the region and type of service:
- 🔧 Official dealer Nissan:
3 500–5 000 ₽(with original belt). - 🛠️ Independent service:
1 500–2 500 ₽(with your spare part). - 👨🔧 Self-replacement:
500–1 500 ₽(cost of belt + roller if necessary).
If you decide to change the belt yourself, please note: hidden costs:
- 🔹 Tension roller -
1 200–2 000 ₽(it is recommended to change along with the belt). - 🔹 Pulley cleaner -
300–500 ₽(if there are traces of oil or dirt). - 🔹 Torque wrench -
1 000–1 500 ₽(for precise tightening of bolts).
Saving on a video is a common mistake. For example, on Murano Z50 a worn tensioner bearing may jam through 5–10 thousand km after replacing the belt, which will lead to its breakage. In this case, repairs will cost 8 000–12 000 ₽ (belt + roller replacement + generator diagnostics).
Owner reviews: real operating experience
Analysis of reviews on forums (Drive2, MuranoClub) shows that most drive belt problems are Nissan Murano due to two factors:
- Quality of spare parts. Owners who installed cheap belts (
200–400 ₽), encounter cliffs already after10–20 thousand km. - Late replacement. Those who ignored the whistling and cracking subsequently spent up to
20 000 ₽for repair of a generator or power steering.
Case study:
📌 "On my own Murano Z51 2010, I ignored the whistling of the belt, I thought it would go away. A month later, the belt broke on the highway, and along with it the generator bearing failed. Result:
18 000 ₽for repairs instead1 500 ₽to replace the belt." — Alexey, Moscow.
Positive feedback regarding belts Gates And Contitech - they serve 80–100 thousand km even in difficult conditions. Owners Z52 note that the original belt 11720-4M00A albeit expensive (3 500–4 000 ₽), but it justifies itself with reliability.
FAQ: Frequently asked questions about the Nissan Murano drive belt
🔹 Is it possible to drive with a whistling belt?
Short term - yes, but no more 1–2 weeks. A whistle indicates slippage, which leads to undercharging of the battery and overheating of the belt. If you ignore the problem, the belt may break or burn the pulleys.
🔹 Which belt is better - original or Gates?
They are comparable in terms of reliability. Gates Micro-V often exceeds the original in terms of resource (up to 100 thousand km), but on Murano Z52 with a hybrid installation it is better to install the original - it is optimized for high load.
🔹 Do I need to change the rollers when replacing the belt?
Be sure to check their condition. If the tension roller is loose or noisy, it needs to be replaced. Cost of the video - 1 200–2 000 ₽, but jamming it will cost many times more.
🔹 Why does the belt wear out quickly on the Murano Z50?
On this generation the engine VQ35DE has a higher torque, and the pulleys are located at a greater angle. This increases the load on the belt. A worn power steering pump or alternator bearing may also be to blame.
🔹 Is it possible to install a belt from another Nissan?
Only if the articles match. For example, a belt from Nissan Pathfinder R51 with engine VQ35DE suitable for Murano Z51, but you need to check the length and number of edges. Using the belt from X-Trail or Qashqai unacceptable - it is shorter and narrower.
