Introduction: Why Drive Belt Diagram Qashqai so important?
Drive belt in Nissan Qashqai - this is not just a consumable, but a critical element on which the operation of the generator, power steering, air conditioning and pump (on some modifications) depends. An error when installing it or choosing the wrong article may lead to belt slippage, engine overheating or even a breakdown along the way. This topic is especially relevant for owners Qashqai J10 (2007–2013) and J11 (2014–2021), where attachment patterns differ depending on engine type (HR16DE, MR20DE, M9R).
In this article you will find not only detailed diagrams with the designation of rollers and pulleys, but also step-by-step instructions for replacement, including unique nuances for diesel versions Qashqai with engine M9Rwhere the injection pump drive belt requires special attention. We will also look at how to check belt wear without removing it and what tools are really needed for the job (spoiler: a set of sockets with an extension is not a luxury, but a necessity).
Drive belt diagrams for different engines Nissan Qashqai
Attachment patterns vary depending on the engine model and year of manufacture. Below are current diagrams for the most common modifications:
1. Gasoline engines HR16DE (1.6 l) and MR20DE (2.0 l)
On these engines, the drive belt serves the generator, air conditioning compressor and power steering pump. On Qashqai J11 with MR20DE (after 2017) a deflection roller was added to reduce the load.
Schematic for HR16DE (2007–2021)
- 🔄 1 — Crankshaft pulley
- ⚡ 2 — Generator
- ❄️ 3 — Air conditioning compressor
- 🔧 4 — Tension roller (automatic)
- 💦 5 — Power steering pump
For MR20DE the scheme is similar, but added deflection roller between the crankshaft pulley and the generator. This is due to the increased belt length (see table below).
2. Diesel engines M9R (1.5/1.6/2.0 l)
Everything is more complicated here: in addition to the standard drive belt, on diesel Qashqai there is a separate drive belt injection pump (high pressure fuel pump). Its break leads to immediate engine shutdown. The scheme includes:
- 🔄 Crankshaft pulley (drive)
- ⚡ Generator
- ❄️ Air conditioning compressor
- 🛢️ injection pump (diesel only)
- 🔧 Tension and deflection rollers
⚠️ Attention: On diesel Qashqai after 2015, a belt was installed with reinforced cord (article11920-4M51A). Using the old article (11920-4M50A) will lead to premature wear!
Table: articles and sizes of belts for Nissan Qashqai
| Engine | Belt number | Length (mm) | Number of ribs | Notes |
|---|---|---|---|---|
HR16DE (1.6 l, petrol) |
11920-ED00A |
1770 | 6 | For models up to 2013 |
MR20DE (2.0 l, petrol) |
11920-4M50A |
1985 | 6 | With deflection roller (after 2017) |
M9R (1.5/1.6/2.0 l, diesel) |
11920-4M51A |
2135 | 8 | Reinforced cord, only for injection pump |
H5FT (1.3 l, turbo, from 2021) |
11920-4M60A |
1890 | 6 | New engine for Qashqai J12 |
When purchasing a belt, pay attention to number of ribs - it must match the original. For example, on diesel Qashqai an 8-groove belt is installed, whereas on gasoline engines there is a 6-groove belt. Using the wrong size will result in slippage and accelerated wear of rollers.

When to change the drive belt: signs of wear and regulations
The manufacturer recommends replacing the drive belt every 90,000 km or once every 4–5 years (whichever comes first). However, in practice, the resource may be reduced to 60,000 km when operating in conditions:
- 🌡️ Extreme temperatures (frost below -30°C or heat above +40°C)
- 💦 High humidity or frequent trips through puddles
- 🏗️ Dusty area (for example, dirt roads)
- 🚗 Aggressive driving style with abrupt starts
How to determine wear without removing the belt?
- Visual inspection: cracks, delaminations or shiny areas (indicate cord wear).
- Extraneous sounds: Whistle when starting the engine or when turning on the air conditioner.
- Unstable operation of the attachment: dim headlights (problems with the generator) or heavy steering wheel (power steering malfunction).
⚠️ Attention: On diesel Qashqai Wear of the injection pump drive belt is often disguised as problems with the fuel system. If the engine stalls while driving, first check belt tension!
To extend the life of the belt, avoid idling the engine for long periods of time with the air conditioning turned on - this creates maximum load on the drive.
Step-by-step instructions for replacing the drive belt
To replace the belt you will need:
- 🔧 Set of sockets (10, 12, 14 mm) with extension
- 🔩 Socket wrench for tension roller
- 📏 Ruler or caliper (to check deflection)
- 🛠️ New belt and rollers (if replacement is required)
Important: On Qashqai J11 with engine MR20DE To access the tensioner you will have to remove it right headlight and fender liner. On diesel versions additional dismantling is required air filter.
☑️ Preparing to replace the belt
How to fix the crankshaft pulley?
Use a 19mm socket and extension against the side member or subframe. An alternative is an assistant who will engage 5th gear and apply the brake.
Replacement algorithm:
- Loosen the tension roller (at HR16DE - with a 14 mm wrench, on MR20DE - special socket wrench
Nissan 07908-4N100). - Remove the old belt, remembering its route (it's better to take a photo).
- Check the condition of the rollers: play or noise during rotation is a reason for replacement.
- Install the new belt, starting at the crankshaft pulley, then clockwise.
- Tension the belt by turning the tension roller counterclockwise (tension torque: 80–100 Nm for gasoline engines, 120 Nm - for diesel engines).
- Check the tension: the belt deflection between the generator and crankshaft pulleys should be 8–10 mm when pressed with a force of 10 kg.
After installation, start the engine and check:
- No whistling or vibration.
- Generator operation (the voltage at the battery terminals should be 13.8–14.4 V).
- Belt tension (it is recommended to tighten it after 500 km).
On diesel Qashqai After replacing the injection pump belt, be sure to bleed the fuel system, otherwise the engine will not start!
Typical replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to premature belt wear or breakdown of attachments. Here are the most common:
- Incorrect tension:
- 🔴 Weak: the belt slips, whistles, the battery is not charged.
- 🔴 Strong: accelerated wear of generator bearings and rollers.
Solution: Use a torque wrench and check the belt deflection.
Leads to cord delamination already after 10,000 km. Always follow the direction of rotation marks (arrows on the belt).
If the rollers are worn out, the new belt will last 2-3 times less. On Qashqai with a mileage of >100,000 km, the rollers are changed necessarily.
For example, on MR20DE the belt must go around the idler roller from the outside. An error will lead to the belt coming off.
⚠️ Attention: On Qashqai J10 With an air conditioner, when replacing the belt, you cannot remove the compressor pulley - this will lead to freon leakage! Use a special puller to fix the pulley.
How to choose a quality belt: original vs analogues
Original belts Nissan (see table above for article numbers) last longer, but cost 2–3 times more than analogues. Is it worth overpaying? Let's compare:
| Brand | Service life | Price (RUB) | Features |
|---|---|---|---|
| Nissan (original) | 80–100 thousand km | 3 500–5 000 | Reinforced cord, minimal play |
| Gates (6PK1770) | 70–90 thousand km | 1 800–2 500 | Good price/quality ratio |
| Contitech (6PK1985) | 60–80 thousand km | 2 000–3 000 | Soft material, but stretches faster |
| Dayco (6PK2135) | 50–70 thousand km | 1 500–2 200 | Budget option, suitable for temporary replacement |
Our advice: for Qashqai with mileage up to 150,000 km is optimal Gates or Contitech. For diesel versions or cars with mileage >200,000 km, it is better to take original — savings on the belt will result in repair of the generator or fuel injection pump.
Professional life hack: When purchasing an analogue, check country of origin. Belts Gatesmade in Belgium last longer than the same ones Gates, but produced in China or Turkey.
FAQ: Frequently asked questions about the drive belt Nissan Qashqai
Is it possible to drive with a squealing belt?
Short-term - yes, but this is a signal about slippagewhich leads to:
- Undercharged battery (risk of being left without electronics).
- Engine overheating (if the belt turns the pump).
- Accelerated wear of the belt and rollers.
Whistle when starting cold is a sign thickened grease in roller bearings. In this case, they need to be replaced.
Which belt to put on Qashqai J12 (from 2021) with engine H5FT?
For a new turbo engine H5FT (1.3 L) fits belt 11920-4M60A length 1890 mm. Features:
- Reinforced design for turbine operation.
- Requires special tensioner (
Nissan 21060-4M60A). - Replace every 75,000 km (the regulations are stricter due to increased loads).
What happens if the belt breaks on a diesel engine? Qashqai?
On diesel engines M9R A break in the fuel injection pump drive belt leads to:
- Immediately stop the engine (without fuel).
- Possible valve damage (if the belt gets into the timing drive).
- Necessities pumping the fuel system after replacement.
⚠️ Important: On diesel Qashqai The injection pump belt is changed every 60,000 km - this is critical!
Do I need to change the rollers along with the belt?
Yes, if:
- Vehicle mileage >100,000 km.
- The rollers make noise or have play.
- You install the belt on Qashqai with a turbo engine or diesel.
Exception: if the rollers were replaced separately less than 30,000 km ago, they can be left.
Is it possible to install a belt from Renault on Nissan Qashqai?
Technically yes, since Qashqai And Renault Kadjar built on the same platform. However:
- Belt part numbers may differ (for example, for
HR16DEfitsRenault 8200840427, but the length is 5 mm shorter). - Quality of original belts Nissan higher than that Renault (based on service reviews).
If you decide on an analogue, check exact length and number of ribs!
