Replacing the timing chain on a <em>Nissan Murano Z50</em>: timing, signs of wear and step-by-step analysis

Nissan Murano Z50 (2008–2014) with motor VQ35DE — a reliable crossover, but even its gas distribution mechanism does not last forever. The timing chain here is considered “eternal” only by marketing standards: in practice, it stretches, the dampers and tensioners wear out, which threatens jumping of links onto sprocket teeth and meeting of valves with pistons. The consequences of such an “acquaintance” are a major overhaul of the engine with a budget of 300,000 rubles.

Owners Murano Z50 People often ask questions: when to change a chain, how to check its condition without disassembling it, and is it possible to save money on original spare parts? This article contains detailed answers with an emphasis on real replacement times (and not those indicated in the manual), symptoms of critical wear And step by step instructions for those who decide to work with their own hands. We will also look at the myths about “indestructible” chains Nissan and provide data on the cost of work in services in Moscow and the regions.

Timing for replacing the timing chain Nissan Murano Z50: official and real

In the manual Nissan for Murano Z50 with engine VQ35DE (3.5 l) the timing chain resource is indicated - 150,000 km. However, this indicator is relevant for “ideal” conditions: regular maintenance, high-quality oil and no overheating. In Russian reality, the chain begins to “make noise” after 100,000–120,000 km, and to 160,000–180,000 km requires mandatory replacement.

Factors that shorten the life of the chain:

• 🛢️ Irregular oil changes or the use of cheap semi-synthetic compounds. The chain is lubricated with oil, and its low quality accelerates the wear of the links.
• 🔥 Engine overheating. At temperatures above 105°C, the metal of the chain loses strength, stretches and “sags”.
• 🚗 Aggressive riding with frequent jerks and high speeds. Shock loads destroy dampers and tensioners.
• ❄️ Operation in cold weather without preheating. Cold oil lubricates the chain less well, increasing friction.

As practice shows, in 70% of cases the chain is Murano Z50 requires replacement 140,000–160,000 km. But there are exceptions: with careful use and oil 5W-30/40 from Mobil 1 or Liqui Moly the chain “runs” up to 200,000 km. However, it’s not worth the risk: a broken chain while running is several times more expensive than a preventative replacement.

Signs of timing chain wear: how to recognize the problem

The timing chain wears out gradually, and Murano Z50 “signals” about the problem in advance. The main thing is not to ignore these symptoms:

1. Noise from under the hood on a cold engine

• 🔊 Metal clang at startup, which disappears after warming up. This chain “hits” the damper due to low tension.
• 🔊 Extraneous rustling at idle speed - a sign of a stretched chain or worn sprockets.

2. Problems with starting and running the engine

• ⚡ Engine troubles or “tweaks” at idle. A possible reason is a shift in valve timing due to a stretched chain.
• ⚡ Power dips during acceleration. The chain can jump 1-2 teeth, disrupting the timing of the valves and pistons.

3. Visual and diagnostic signs

• 🔧 Chain play during manual check (if you remove the timing cover). Allowable play is up to 5 mm; if more, replacement is required.
• 📊 Sensor errors: P0011 (camshaft timing offset) or P0340 (camshaft position sensor malfunction).

⚠️ Attention: If on Murano Z50 appeared constant metallic knocking (not only when cold), the chain is already critically worn. Operating a car in this condition is dangerous - the risk of a break increases 5 times.

What happens if you ignore the circuit noise?

If the timing chain breaks on Nissan Murano Z50 with motor VQ35DE the valve bends in 90% of cases. This occurs due to the “meeting” of the pistons with the open valves at high speeds. Consequences:

- Bending of intake/exhaust valves (from 4 to 16 pieces).

- Damage to the pistons and cylinder head.

- Overhaul of the engine with replacement of the cylinder head (from 250,000 ₽).

In rare cases (if the break occurred at idle), you can get away with replacing the chain and tensioners, but this is rather an exception.

What parts to change along with the timing chain: complete set

Replacing only the chain without accompanying elements is a half-measure. On Murano Z50 it is critical to change entire timing belt kit, since the wear of one component accelerates the destruction of the others. The minimum set includes:

Detail	Original article	Analogs (brand)	Cost, ₽
Timing chain	13028-4M01A	Febi, SKF, Contitech	8 000–12 000
Chain tensioner	13070-4M000	Aisin, Gates	4 500–7 000
Chain guide (upper)	13085-4M000	Nipparts, Blue Print	2 500–3 500
Chain guide (lower)	13086-4M000	Febi, Meyle	3 000–4 000
Camshaft sprocket	13025-4M000	GMB, Koyo	5 000–8 000

It is also recommended to replace:

• 🔧 Timing cover gasket (13035-4M000) - costs 1,500–2,000 ₽, but may leak when used repeatedly.
• 🔧 Oil pump (if there is play or noise) - its resource often coincides with the life of the chain.
• 🔧 Cooling pump (21010-4M005). Its jamming leads to a break in the generator belt and overheating.

⚠️ Attention: Saving on tensioners or dampers is expensive. For example, a worn damper may wipe the chain through beyond 5,000 km, which will lead to its breakage. Services often offer a “budget” set without sprockets - this is risky, since worn sprockets speed up the stretching of the new chain.

The cost of replacing a timing chain: prices in services and self-repair

Timing chain replacement price Nissan Murano Z50 depends on the region, service level and selected spare parts. Average prices in Russia (for 2026):

Service type	Cost of work, ₽	Cost of spare parts (original), ₽	Total, ₽

Self-replacement	0 (tool required)	25 000–40 000	25 000–40 000

Replacing the timing chain yourself Murano Z50 possible, but requires:

• 🔧 Special tool: camshaft clamps (Nissan SST KV10112100), crankshaft pulley puller, torque wrench.
• 📐 Accurate adherence to marks. An error of 1 tooth will lead to a phase shift and tripping of the motor.
• ⏳ 10–12 hours time (for beginners - up to 2 days). Disassembly requires removal of the pan, oil pump and front cover.

If you decide to change the chain yourself, take photographs of the position of all marks and bolts before analysis. This will help avoid assembly errors. It is also recommended to use new sprocket mounting bolts (13005-4M000), since the old ones may become loose after tightening.

Step-by-step instructions for replacing the timing chain with Nissan Murano Z50

To replace the timing chain you will need:

• 🔧 Set of sockets and keys (including 10 mm, 12 mm, 14 mm).
• 🔧 Torque wrench (bolt tightening torque - 20–25 Nm).
• 🔧 Sealant Loctite 574 for gaskets.
• 🔧 Camshaft clamps (Nissan SST KV10112100 or analogues).

Step 1. Preparing and removing the timing cover

• ⚡ Disconnect the battery (minus first).
• ⚡ Drain the oil and antifreeze.
• ⚡ Remove the alternator belt, crankshaft pulley and front timing cover (12 bolts).

Step 2. Fixing the marks and removing the old chain

• ⚡ Rotate the crankshaft until the marks on the camshaft sprockets and the cylinder block align.
• ⚡ Secure the camshafts with a special device.
• ⚡ Loosen the chain tensioner and remove it along with the dampers.

Step 3: New chain installation and assembly

• ⚡ Install new sprockets, dampers and tensioner.
• ⚡ Put on the chain, aligning the marks (the white links on the chain should match the marks on the sprockets).
• ⚡ Tighten the bolts firmly 20–25 Nm (use a torque wrench!).

Common mistakes when replacing a timing chain and how to avoid them

Even experienced craftsmen make mistakes when working with timing belts. Nissan Murano Z50. Here are the most common:

1. Using an old water pump or oil pump

Many people save on these parts, but their wear can undo all the work. For example, a jammed pump leads to overheating, and a worn oil pump leads to oil starvation of the chain.

2. Incorrect bolt tightening

The camshaft sprocket bolts must be tightened to a torque 20–25 Nm. Overtightening threatens to break the thread, and weak tightening can cause the sprocket to turn and phases to shift.

3. Ignoring tags

On Murano Z50 marks are applied to the sprockets, cylinder block and the chain itself (white links). If you don't combine them, the engine will run unstably or won't start at all.

4. Saving on sealant

The timing cover gasket must be installed with sealant Loctite 574 or similar. Without it, oil leaks are possible, which will lead to chain contamination and accelerated wear.

⚠️ Attention: If after replacing the chain with Murano Z50 appeared knocking when cold, check the tensioner. It may not create enough pressure due to an air lock in the oil system. The solution is to warm up the engine to operating temperature and recheck the tension.

FAQ: Answers to frequently asked questions about the timing chain Nissan Murano Z50

Is it possible to drive with a stretched chain if it does not make noise?

No. Even if the chain does not make sounds, its stretching leads to valve timing shift, which reduces engine power and increases fuel consumption. With critical stretch (more than 10 mm), the chain can jump on the sprockets, which will cause the valves to hit the pistons.

What oil should I use after replacing the chain?

For Murano Z50 with motor VQ35DE oil recommended 5W-30 or 5W-40 with permission API SN or ILSAC GF-5. Optimal brands: Mobil 1 ESP 5W-30, Liqui Moly Special Tec AA 5W-30, Idemitsu Zepro Touring 5W-30. Oil needs to be changed every 7,000–10,000 km.

How long does a timing chain last after replacement?

If installed correctly and using high-quality oil, the new chain will last 150,000–200,000 km. However, the service life depends on operating conditions: in city mode with frequent traffic jams, the chain wears out faster than on the highway. It is recommended to check its condition every 50,000 km after replacement.

Is it possible to replace the timing chain without removing the engine?

Yes, on Murano Z50 The chain can be changed without dismantling the engine, but the front timing cover, pan and oil pump must be removed. This is a labor-intensive process that takes 8–12 hours. Services often offer a “simplified” option without replacing sprockets - this is risky, since worn sprockets accelerate the stretching of the new chain.

What should I do if the Check Engine light comes on after replacing the circuit?

Error Check Engine after replacing the chain it is usually associated with incorrect alignment of marks or a malfunction of the camshaft position sensor (P0340). Solution:

1. Check the alignment of the marks on the sprockets and the cylinder block.
2. Clear errors with the scanner (for example, ELM327).
3. If the error remains, check the camshaft sensor (23731-AL50A) and its connector.
