Tensioner roller in the accessory drive system Nissan Note - a small detail, but critically important. Not only the life of the alternator belt, but also the stable operation of the air conditioner, power steering (if equipped) and even the generator itself depends on its condition. Owners Note The first (E11) and second (E12) generations often experience premature roller wear due to the design features of the engines HR15DE And HR16DE, where the load on the drive is above average.
In this article we will look at how recognize a faulty tension roller by indirect evidence, without disassembling the engine, which articles and brands of spare parts choose a replacement, and how to do the work yourself - taking into account the pitfalls that are specific to Nissan Note. We will also provide data on service life rollers from different manufacturers and typical mistakes made when replacing.
Signs of a faulty tension roller Nissan Note
The first symptoms of roller wear are often attributed to problems with the generator belt or unit bearings. However, there are a number unique features, which directly point to the video:
- 🔊 Whistling or squeaking during a cold start of the engine, which disappears after warming up (due to a change in belt tension when heated).
- 🌀 Belt vibration at idle, noticeable when the hood is open - the belt “bounces” on the pulleys.
- 🔄 Uneven belt wear: one side wears faster than the other (indicates the roller is skewed).
- 🚨 Extraneous noise (hum, crackling) from the drive side, increasing when the air conditioner or power steering is turned on.
On Nissan Note with engines HR15DE/HR16DE there is a special feature: the roller is integrated with automatic tensioner. If upon visual inspection you notice that the tensioning mechanism has sagged and does not keep the belt tensioned even after manual adjustment, this is a sure sign to replace the entire assembly.
You can check the roller with a simple test: with the engine off, press the belt between the generator and crankshaft pulleys. If the deflection exceeds 10–15 mm, and after starting the engine a whistle is heard - the roller or its bearing is worn out.
- Once every 10,000 km
- Only when there is noise
- Never checked
- After every oil change
Which rollers are suitable for Nissan Note: articles and analogues
On Nissan Note Two types of tension rollers are installed depending on the year of manufacture and configuration:
| Engine model | Original article | Analogs (brand + article) | Notes |
|---|---|---|---|
HR15DE (2006–2013) |
11920-ED00A |
|
Suitable for models without air conditioning |
HR16DE (2013–2020) |
11920-4M00A |
|
For versions with air conditioning and power steering |
Important: on Note second generation (E12) with engine HR16DE was installed tensioner with damper (article 11950-4M00A). It cannot be replaced with a roller from HR15DE — the mounting geometry is different!
Among analogues, the best price/quality ratio is Gates And NTN. The latter, by the way, are the original supplier for Nissan. Budget options (for example, Febi or Blue Print) last 1.5–2 times less - they should be considered only as a temporary replacement.
⚠️ Attention: There are many fake brands on the market NTN And SKF. The original rollers have a laser engraved logo on the body and are supplied in branded packaging with a hologram.
When to change the tension roller: regulations and real life
According to the regulations Nissan The tension roller does not have a clear replacement period - it is checked every time the alternator belt is replaced (every 60,000–90,000 km). However, in real operating conditions (city traffic jams, frequent engine starts, high humidity), the roller life is reduced to 40,000–60,000 km.
Factors that accelerate wear:
- 🌡️ Engine overheating — leads to deformation of the plastic elements of the tensioner.
- 💦 Oil or antifreeze ingress on the belt and roller (destroys the rubber bearing seals).
- 🔧 Poor quality belt replacement — if the belt is overtightened or loosened, the roller operates with increased load.
- ❄️ Operation in winter — low temperatures increase the load on the bearing during cold starts.
In practice, most owners Nissan Note change the roller together with the generator belt - this allows you to save on work and avoid repeated dismantling. Average cost of a set (belt + roller) from Gates - about 3 500–4 500 ₽.
If, when replacing the alternator belt, you notice that the tension roller is loose or rotates with difficulty, be sure to change it, even if it looks normal on the outside. The bearing could have already begun to deteriorate, and after 5–10 thousand km a belt break awaits you.
Step-by-step instructions for replacing the tension roller
To replace the roller with Nissan Note you will need:
- 🔧 Set of sockets and ratchet wrench (head on
14 mmfor the roller bolt). - 🔨 Socket wrench on
10 mmfor fastening the tensioner. - 🔩 Torque wrench (optional, for precise tightening).
- 📏 A ruler or a special tool for checking belt tension.
Sequence of actions:
- Remove the alternator belt:
- Loosen the tension roller bolt (head on
14 mm). - Turn the tensioner counterclockwise (use the socket on
10 mmfor support) and remove the belt.
- Loosen the tension roller bolt (head on
- Remove the old roller:
- Unscrew the roller mounting bolt completely and remove it from the bracket.
- Clean the seat from dirt and old grease residues.
- Install a new video:
- Apply some lubricant (eg Litol-24) onto the roller axis.
- Tighten the fastening bolt to a torque
40–45 Nm(do not overtighten!).
- Put on the belt and adjust the tension:
- Turn the tensioner clockwise until the marks align (on the rocker arm and bracket).
- Check the tension: the belt deflection between the generator and crankshaft pulleys should be
8–10 mmwhen pressed with force10 kg.
- No play in the new video (shake it with your hand)
- Coincidence of marks on the tensioner
- No belt skew (it must lie flat on all pulleys)
- Generator operation (battery voltage should be 13.8–14.4 V at idle) -->
On Nissan Note with air conditioning, when replacing the roller, it is also recommended to check the condition deflection roller (article 11905-4M00A). It often wears out at the same time as the tension one.
⚠️ Attention: On engines HR16DE after 2016 release, the tensioner has plastic rocker, which may crack if excessive force is applied. Do not use a lever to turn the tensioner - only a head with a ratchet wrench!
Typical replacement mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes that lead to premature failure of the roller. Here are the most common:
- 🔧 Roller bolt tightening — leads to deformation of the seat and backlash. The tightening torque should not exceed
45 Nm. - 🌀 Incorrect belt tension:
- Weak tension → slipping and whistling.
- Excessive tension → accelerated wear of generator and roller bearings.
- 🛠️ Using non-original O-rings - leads to oil leakage onto the belt.
- 🔄 Replacing only the roller without checking the belt - if the belt is worn out, it will quickly kill the new roller.
Another typical problem is incompatibility of spare parts. For example, on Note E12 with engine HR16DE some craftsmen install a roller from Renault Logan (article 7701473708). It is similar in appearance, but has a different rocker arm angle, which leads to belt misalignment and accelerated wear.
What happens if you ignore the squealing of the belt?
If you ignore the whistle caused by wear on the tension roller, the consequences can be serious:
- Broken alternator belt → battery discharge, failure of power steering and air conditioning.
- Roller bearing jamming → belt breakage and possible damage to the crankshaft pulley.
- Overheating of the generator due to belt slippage → failure of the diode bridge.
Replacement cost: yourself vs service
Cost of replacing the tension roller Nissan Note varies depending on region and type of service:
| Service type | Cost of work (₽) | Cost of spare parts (₽) | Total (₽) |
|---|---|---|---|
| Official dealer Nissan | 2 500–3 500 | 4,000–6,000 (original) | 6 500–9 500 |
| Unofficial service | 1 200–2 000 | 2,500–4,000 (analog) | 3 700–6 000 |
| Self-replacement | 0 | 2 500–4 000 | 2 500–4 000 |
Replacing it yourself can save you up to 60% cost, but requires care. The main difficulty is access to tensioner: on Note with air conditioning you have to remove the right headlight or engine protection.
If you decide to contact a service center, choose one that uses a torque wrench to tighten the bolts. This ensures that the roller will not be over or under tightened.
Saving on the quality of the roller is more expensive: cheap analogues last 2–3 times less than the original, and their replacement requires the same labor costs. Optimal choice - NTN or Gates.
How to extend the life of a tension roller
The service life of the roller can be increased by following a few simple rules:
- 🔄 Check belt tension regularly - every
10,000 kmor before long trips. - 🚿 Avoid contact with water and dirt on the belt and pulleys. After washing the engine, blow out the drive with compressed air.
- 🛢️ Keep the engine compartment clean - oil stains on the belt reduce its service life by
30–40%. - ❄️ In winter Allow the engine to warm up before driving - this will reduce the load on the roller bearing.
It is also recommended to lubricate once a year roller axis (not the bearing!) high-temperature grease (for example, Molykote G-Rapid Plus). This will prevent corrosion and make the mechanism easier to rotate.
On Nissan Note with mileage over 150,000 km it is worth paying attention to the condition crankshaft pulley. Its wear (beating, chipping) accelerates the destruction of the belt and roller.
FAQ: Frequently asked questions about the tension roller Nissan Note
Is it possible to drive with a whistling roller?
Short term - yes, but no more 1–2 weeks. Whistling indicates belt slippage, which leads to accelerated wear and risk of belt breakage. In addition, if the roller whistles due to a worn bearing, it may jam, which will lead to a broken belt and loss of battery charge, as well as failure of the power steering and air conditioning.
Which video is better - the original or the analogue?
Original videos (NTN) last longer, but also cost 1.5–2 times more than analogues. The best option in terms of price/quality ratio - Gates or SKF. Budget brands (Febi, Blue Print) are suitable for temporary replacement only.
Do I need to change the alternator belt along with the pulley?
Yes, if the belt has been used for more than 60,000 km or has visible cracks or delaminations. A new roller with a worn belt will last 2–3 times less. An exception is if the belt has been replaced recently (less than 20,000 km back) and is in perfect condition.
What should I do if the belt whistles after replacing the roller?
The reasons may be the following:
- Insufficient belt tension - check the marks on the tensioner.
- If grease or dirt gets on the belt, clean it with alcohol.
- Poor quality roller - check for play and ease of rotation.
- Worn alternator pulley or crankshaft - inspect them for runout.
If the whistle does not go away, contact the service for diagnostics.
Is it possible to replace the pulley without removing the timing belt?
Yes, on Nissan Note with engines HR15DE/HR16DE The timing belt and alternator belt are not connected to each other. Replacing the tension roller of the auxiliary drive does not require intervention in the gas distribution mechanism.
