Timing chain (timing chain) in Nissan Qashqai J10 with motor MR20DE 2.0 l - a critical element, the condition of which determines the performance of the engine. Unlike a timing belt, a chain is considered more reliable, but it also has a limited resource. Missing the timing of replacement may result in chain jump, collision of pistons with valves and engine overhaul costing from 200,000 rubles.
Owners Kashkaya J10 questions are often asked: when exactly is replacement required, is it possible to determine wear by symptoms, and is it worth trusting “silent” chains from third-party manufacturers? This guide contains an analysis of all the nuances: from regulatory deadlines to step-by-step instructions with photos and videos, as well as an analysis of common mistakes when replacing yourself.
Regulations for replacing the timing chain: official deadlines and actual service life
Manufacturer Nissan in the manual for Qashqai J10 (2007–2013) indicates that the timing chain does not require replacement during the entire service life of the vehicle. However, this thesis is valid only for ideal operating conditions: moderate climate, high-quality oil and a gentle driving style. In Russian realities, the life of the chain is reduced by 1.5–2 times.
Experts and service station foremen recommend focusing on the following indicators:
- 📅 Mileage: 150–180 thousand km - scheduled replacement, even if there are no signs of wear.
- ⏳ Time: 8–10 years - the chain “ages” due to the loss of elasticity of the plastic tensioners and dampers.
- 🛢️ Oil: if low-quality mineral or semi-synthetic oil was used, the chain can stretch to 100 thousand km.
It is important to consider that the engine MR20DE equipped two timing chains: main (camshaft drive) and auxiliary (oil pump drive). The second one fails less often, but its condition also needs to be monitored. When replacing the main circuit, it is recommended to update the auxiliary one, despite the higher cost of the kit.

Signs of timing chain wear: how to recognize the problem in time
A stretched or worn chain makes itself felt long before it becomes critical. The main thing is not to confuse these symptoms with malfunctions of other components (for example, the generator belt tensioner or engine mounts). Pay attention to the following “bells”:
- 🔊 Knocking or clanging in the front part of the engine when cold (especially noticeable in the first 10–15 seconds after starting). The sound may disappear after warming up, but this does not mean that the problem has disappeared.
- 📉 Floating speed at idle speed - a sign of poor valve timing.
- ⚡ Check Engine with errors
P0011,P0014,P0340orP0345- indicate a discrepancy between the timing marks. - 🚗 Jerks during acceleration or loss of power - the chain may slip by 1-2 teeth.
For an accurate diagnosis, use endoscope (through the oil filler neck) or remove the valve cover. Critical wear is determined by:
- 📏 Chain stretching by more than 5–7 mm (measured with a ruler between the stretched sections).
- 🔧 Backlash of dampers and tensioners (more than 1–2 mm).
- 💥 Cracks or chips on the plastic parts of the mechanism.
⚠️ Attention: if the chain has slipped by 3 teeth or more, the engine MR20DE is guaranteed to suffer damage to the valves. In this case, it will be necessary to disassemble the cylinder head and replace the guide bushings, and sometimes the valves themselves.
Replacement kit: what to buy and which brands to choose
When replacing the timing chain with Nissan Qashqai J10 2.0 It is not enough to buy just the chain itself. You will need a complete kit including:
| Component | Original art. | Analogs (brand) | Note |
|---|---|---|---|
| Main timing chain | 13028-4M51A |
Febi (22626), SKF (VKT 10032) | Length 124 links |
| Auxiliary chain (oil pump) | 13085-4M500 |
Gates (T43188), Contitech (CT1188K1) | Length 80 links |
| Chain tensioner (hydraulic) | 13070-4M500 |
Ajusa (21425000), Nipparts (J1412050) | Updated version with metal body |
| Chain guide (upper) | 13088-4M500 |
Corteco (25016709), Elring (547.520) | Often breaks during dismantling |
| Camshaft sprockets | 13025-4M51A (intake), 13026-4M51A (issue) |
GMB (130-1020/130-1030) | It is recommended to replace if the chain is severely worn |
The cost of the original set is from Nissan - about 25,000–30,000 rubles. Analogs will cost less (RUB 15,000–20,000), but it is important to avoid fakes. For example, chains Febi or SKF often counterfeited - buy only from official dealers or trusted suppliers (exist.ru, emex.ru).
⚠️ Attention: If you buy a set from a third-party brand, be sure to check the chain length (number of links) with the original. Some "universal" chains may be 1-2 links too short, which will result in incorrect installation.
Before purchasing a kit, check it for compatibility with your VIN code through the service Partsouq or Nissan TechInfo. This will help avoid mistakes with the year of manufacture or engine modification.
Step-by-step instructions for replacing the timing chain
Replacing the chain with Qashqai J10 - a labor-intensive process that requires special tools and skills. If you are not confident in your abilities, it is better to entrust the work to professionals. Below is a step-by-step guide for experienced car owners.
Necessary tools and conditions
- 🔧 Set of sockets and keys (10, 12, 14, 17 mm).
- 🔩 Torque wrench (tightening torque 20–25 Nm).
- 🛠️ Crankshaft pulley puller (
Nissan SST: KV10112100). - 🔗 Chain wrench for holding the pulley.
- 📐 Vernier calipers for checking chain stretch.
- 🚗 Lift or inspection hole.
Stages of work
- Removing the front bumper and protection. Disconnect the battery, drain the antifreeze and oil. Remove the radiator and fan.
- Fixation of timing marks. Set the piston of cylinder 1 to TDC (top dead center). The marks on the camshaft and crankshaft sprockets must match the marks on the block.
- Removing the old chain. Loosen the tensioner, remove the dampers and sprockets. Be careful - plastic parts are fragile!
- Installing a new chain. Place the chain on the sprockets, following the marks. Check the tension (deflection no more than 5 mm).
- Assembly and testing. Reinstall all parts, fill with fresh oil and antifreeze. Start the engine and check for any abnormal noise.
☑️ Checklist before assembly
Pay special attention timing marks. On MR20DE they are located:
- 🔄 On the crankshaft - the point on the pulley should look up (12 o'clock).
- 🔄 On camshafts, the marks on the sprockets should be at the level of the upper plane of the cylinder head.
What to do if the marks are lost?
If the marks do not match after installing the chain, you must turn the crankshaft 2 turns (720°) and recheck their position. If the problem persists, the chain is not installed correctly or is stretched.
Common mistakes and how to avoid them
Even experienced craftsmen sometimes make mistakes when replacing a timing chain with Qashqai J10. Here are the most critical of them:
- Ignoring the auxiliary circuit. Many people change only the main chain, forgetting about the oil pump chain. This leads to its break after 30–50 thousand km.
- Retightening sprocket bolts. Tightening torque - 20 Nm. Exceeding will lead to deformation of the threads in the cylinder head.
- Using an old tensioner. The plastic parts of the tensioner wear out and do not provide the required force.
- Incorrect installation of dampers. If the guide is skewed, the chain will rub against the metal, accelerating wear.
Another typical problem is underfilling the oil after replacement. Engine MR20DE requires 4.3 liters oil (including filter). Use only approved synthetics API SN or ILSAC GF-5 (For example, Nissan 5W-40 or Mobil 1 ESP 5W-30).
⚠️ Attention: After replacing the chain, avoid high speeds (more than 3000 rpm) for the first 500 km. This is necessary to break in new parts and distribute the oil evenly.
Replacement cost: service station vs self-repair
Timing chain replacement price Nissan Qashqai J10 varies depending on region and service level:
| Type of work | Cost (RUB) | Time (hours) |
|---|---|---|
| Chain replacement (without spare parts) | 12 000–18 000 | 6–8 |
| Replacement chain + auxiliary chain | 18 000–25 000 | 8–10 |
| Complete set (chains, sprockets, tensioners) | 35 000–50 000 | 10–12 |
| Self-replacement (spare parts only) | 15 000–25 000 | 12–16 |
Saving on spare parts can result in costly repairs. For example, installing a cheap tensioner from no-name- brand often leads to it jamming after 20–30 thousand km, which will require repeated disassembly of the engine.
The best option is to purchase an original kit and replace it at a trusted service station with a guarantee. This is cheaper than repairing the engine after a broken circuit.
Owner reviews and expert opinion
On forums (for example, Qashqai Club Russia or Drive2) owners J10 share their experience of replacing the chain. Here are the most common observations:
- ✅ Positive: after replacement, vibration at idle disappears, acceleration dynamics improve, and the “check” disappears.
- ❌ Negative: Some people experience a knocking sound after replacement - usually a poor-quality tensioner or incorrect installation of dampers is to blame.
Experts recommend:
- 🔧 When replacing a chain, be sure to check the condition phase shifters (they are often clogged with sediment).
- 🛢️ Use engine flushing before changing the oil - this will remove carbon deposits and extend the life of the new chain.
- 📅 News service log, where to record the mileage and date of replacement of the chain, oil, filters.
FAQ: Frequently asked questions about replacing the timing chain
Is it possible to drive if the chain starts knocking?
For a short time (up to 500–1000 km) it is possible, but only if the knocking appears when it is cold and disappears after warming up. If the noise is constant or accompanied by errors P0011/P0014, operate a car it's impossible — there is a high risk of chain jumping.
How long does the timing chain last on a Qashqai J10 after replacement?
If you use original spare parts and high-quality oil, the new chain will last 150–200 thousand km. If you install an analogue (for example, Febi or Gates), the resource may be reduced to 120–150 thousand km.
Do I need to change the oil pump when replacing the chain?
Mandatory if the auxiliary chain (pump drive) is worn or stretched. The pump itself is changed only when the oil pressure decreases (checked with a pressure gauge). In most cases, it is enough to replace the chain and pump sprocket.
Is it possible to replace the timing chain without removing the engine?
Yes, on Qashqai J10 This is possible, but you will need to remove the front bumper, radiator and engine mount. In some cases, you have to jack up the engine to access the bottom.
What oil should I fill in after replacing the chain?
A synthetic oil with a viscosity of 5W-30 or 5W-40 and tolerances API SN/ILSAC GF-5. Optimal options: Nissan Strong Save X 5W-30, Mobil 1 ESP 5W-30, Liqui Moly Top Tec 4200 5W-30.
