Engine 3.5 VQ35DE became a legend among powertrains Nissan - it was installed on Murano first and second generations (Z50/Z51) from 2003 to 2014. This engine combines Japanese reliability, impressive power and ease of operation, but even it has weaknesses, which owners often find out about too late. In this article we will analyze technical specifications, typical breakdowns, nuances service and options tuning - without embellishment and marketing slogans.

It’s worth clarifying right away: VQ35DE - this is not just a “3.5 liter engine”, but the result of decades of evolution of the series VQ, which debuted back in 1994. On Murano he gives out 234–265 hp depending on the year of manufacture and the sales market, but the key difference from analogues (for example, on Nissan 350Z) — adaptation for a heavy crossover. This means a modified cooling system, a modified transmission and... a number of compromises that affect the resource. If you are planning a purchase Murano If you have a used car or already own one, this article will help you avoid costly mistakes.

Technical specifications VQ35DE for Nissan Murano

Engine VQ35DE belongs to the family V6 with an aluminum cylinder block and two camshafts on each bank (DOHC). Its key features:

  • 🔧 Volume: 3498 cm³ (bore × stroke: 95.5 × 81.4 mm)
  • ⚡ Power: 234 hp (Z50, 2003–2007) / 265 hp (Z51, 2008–2014)
  • 📉 Torque: 328–336 Nm at 2800–4800 rpm
  • ⛽ Fuel: AI-95 (recommended), AI-92 with power loss is allowed
  • 🔄 Timing drive: chain (resource 150–200 thousand km, but requires monitoring)
  • 💧 Lubrication system: combined (spraying + under pressure)

Feature Murano — steam-air system NVCS (Nissan Valve Control System), which changes the lift of the intake valves to optimize fuel consumption. In practice, this means that the engine “breathes” differently at low and high speeds, but also complicates the diagnosis of malfunctions. For example, floating idle speed often associated with NVCS, and not with the throttle valve.

Paired with VQ35DE on Murano works variator Jatco JF011E (until 2010) or 6-speed automatic RE7R01A (after 2010). The variator is the weak point of the crossover, but it is unfair to blame only the transmission for its breakdowns: engine overheating accelerates the degradation of oil in the variator by 2–3 times. We'll talk about this in more detail in the section on maintenance.

Weaknesses and typical breakdowns of VQ35DE

Despite the reputation of a “millionaire”, VQ35DE on Murano has a number systemic problems, which appear after 150–180 thousand km. The main ones:

  • 🔥 Overheating and cracks in the cylinder block: This is due to a design defect - thin walls between the cylinders. If overheated (for example, due to a faulty thermostat), the unit may crack. Symptoms: white smoke from the exhaust, oil in antifreeze.
  • 🛢️ Maslozhor: after 200 thousand km, oil consumption of up to 1 liter per 1000 km is the norm for this engine. The reason is wear of the oil scraper rings and stuck piston rings. Is being decided decarbonization or capital.
  • 🔊 Knock of hydraulic compensators: characteristic “tractor” sound when cold. Most often to blame contaminated oil or its low quality. In advanced cases, wear and tear of the expansion joints themselves occurs.
  • ⚙️ Timing chain problems: stretching the chain after 150 thousand km leads to a jump of 1–2 teeth. Consequences: bent valves and major repairs.

Deserves special attention cooling system. On Murano often fails thermostat (stuck in closed position) and pump (leak through the seal). Signs of malfunction:

  • 🌡️ The temperature arrow jumps or shows overheating.
  • 💦 Antifreeze leakage under the car (especially after parking).
  • 🔥 Turn on the cooling fan on a cold engine.
⚠️ Attention: if the dashboard lights up Check Engine Light with code P0300 (lots of misfires), don't ignore it! On VQ35DE this often signals the beginning of the destruction of the catalyst, whose ceramic particles can get into the cylinders and cause scuffing.

Another "sore" - oil leak through valve cover. The problem lies in the deformation of the gasket due to overheating or poor quality material. Solved by replacing the gasket and mandatory check of the flatness of the cover (often it is driven by temperature).

What to do if the engine knocks when cold?

If the knocking of hydraulic compensators does not disappear after warming up, replace the oil with synthetic 5W-30 (for example, Mobil 1 ESP 5W-30) and filter. If the sound remains, the gaps need to be adjusted or the compensators replaced. In 20% of cases, knocking masks a more serious problem: wear of the main liners or piston group. Diagnose oil pressure with a pressure gauge!

Maintenance: how to extend engine life

Resource VQ35DE on Murano amounts to 300–400 thousand km with proper maintenance. Key points:

  1. Oil and filter: replace every 7–8 thousand km (regardless of the dealer's recommendations!). Use only approved synthetics API SN or ILSAC GF-5. Optimal brands: Mobil 1, Liqui Moly, Idemitsu.
  2. Antifreeze: complete replacement every 5 years or 100 thousand km. On Murano recommended Nissan Long Life Coolant (blue) or analogues (CoolStream A-110).
  3. Air filter: check every 15 thousand km, change if visible contamination. A clogged filter increases fuel consumption by 5–10%.
  4. Spark plugs: original NGK PLFR5A-11 or Denso FK16HR11 serve 60–80 thousand km. After 100 thousand km, check the gaps (should be 1.1 mm).

Critical keep an eye on crankcase ventilation system. On Murano it often gets clogged, which leads to an increase in oil pressure and squeezing out the seals. Signs:

  • 💨 Oil in the air duct (check the pipe from the valve cover to the throttle).
  • 🛢️ Rapid oil contamination (darkening 2–3 thousand km after replacement).

To clean the system, remove the valve PCV (located on the valve cover) and wash it in carburetor cleaner. If the valve does not click when blowing, replace it.

Troubleshooting: Symptoms and Error Codes

Engine VQ35DE “speaks” about problems through error codes And behavioral symptoms. Let's look at the most common ones:

Error code Reason What to do
P0300 Multiple misfires Check spark plugs, coils, compression. Valve wear may occur.
P0171/P0174 Lean mixture (air leak) Diagnose vacuum hoses, throttle valve, MAF sensor.
P0420 Low catalyst efficiency Replace lambda probes or catalyst. On Murano Bank 2 often fails.
P0505 Idle system malfunction Clean the throttle, check the throttle position sensor.

If the engine troit, first check:

  1. Spark plugs (carbon deposits, gap).
  2. Ignition coils (check with a tester, resistance should be 5–10 kOhm).
  3. Compression in the cylinders (norm: 12–14 bar, spread between cylinders no more than 1 bar).

Vibration at idle often associated with:

  • 🔧 Worn engine mounts (check visually for cracking).
  • ⚙️ Crankshaft imbalance (less common, but requires autopsy).
  • 🔥 Air suction through cracks in the intake manifold.
⚠️ Attention: If the engine starts to run louder after changing the oil, it is likely that the new oil is not compatible with the remaining oil or has the wrong viscosity. On VQ35DE It is strictly forbidden to mix mineral and synthetic oil - this leads to the formation of sludge and clogging of oil channels.
💡

When buying a used Murano, be sure to check the oil on the dipstick: if it is black and smells like burning, and the mileage is less than 100 thousand km, the engine has not been properly maintained. Refuse to buy or trade 30-50% below the market.

Tuning and modifications: is the game worth the candle?

Engine VQ35DE has potential for tuning, but Murano it's limited crossover weight And transmission strength. Let's consider the options:

  • 🔥 Chip tuning: ECU firmware (for example, UpRev or EcuTek) adds 15–20 hp, but increases the load on the variator. Risk: overheating and accelerated wear of the timing chain.
  • 💨 Cold intake: installing a zero resistance filter (for example, K&N) gives +3–5 hp, but requires frequent cleaning. On dusty roads, such a filter reduces engine life.
  • 🔧 Exhaust system: replacing catalysts with flame arresters (“spiders”) and installing a direct-flow muffler adds 10–15 hp, but makes the car louder (not legal for the EAEU).
  • ⚡ Turbo kit: theoretically possible (for example, based on Garrett GT35), but requires strengthening the block, replacing pistons and adjusting to high pressure. Budget: from 300 thousand rubles, the engine life is reduced by 2–3 times.

The most safe and effective tuning for Murano - this is:

  1. Installation high performance spark plugs (For example, NGK Iridium IX).
  2. Replacement thermostat at 82°C (instead of standard 88°C) for better cooling.
  3. Usage oils with molybdenum (For example, Liqui Moly Molygen 5W-30) to reduce friction.

Important: any tuning required ECU firmware updates. Without this, the engine will not operate optimally, which will lead to detonation and wear.

💡

On a Nissan Murano with a mileage of more than 150 thousand km, any tuning that increases power reduces engine life by 20–30%. Investments in maintenance (oil, cooling, timing) pay off better than boosting.

Comparison with other Nissan engines

How VQ35DE looks compared to other engines Nissan? Let's look at the key differences:

Characteristics VQ35DE (Murano) VQ25DD (Murano Z52) QR25DE (X-Trail) VK56VD (Patrol)
Volume, l 3.5 2.5 2.5 5.6
Power, hp 234–265 234 169 405
Resource, thousand km 300–400 250–300 250–350 350–500
Fuel consumption, l/100 km 11–14 9–11 9–12 16–20
Weaknesses Timing chain, oil supply Turbine, timing chain Timing belt, oil leaks Oil consumption, fuel injectors

Compared to VQ25DD (turbocharged 2.5-liter engine Murano Z52), VQ35DE wins in reliability And maintainability, but loses in efficiency. The naturally aspirated 3.5-liter engine is less sensitive to the quality of fuel and oil, while the turbocharged VQ25DD requires ideal operating conditions.

C QR25DE (installed on X-Trail) VQ35DE It’s difficult to compare - these are engines of different classes. QR25DE cheaper to maintain, but less powerful and dynamic. But VK56VD (5.6-liter V8 on Patrol) is a different level: more power, but also more problems with fuel consumption and the environment.

Choosing between a new and used engine: which is cheaper?

If your VQ35DE requires major repairs, the question arises: repair the old one or buy a contract one? Let's look at the pros and cons of each option:

  • 🔧 Major repairs:
    • ✅ Pros: you keep the “native” engine, you know its history.
    • ❌ Cons: cost 150–250 thousand rubles, risk of repeated problems (for example, if the cause of overheating is not eliminated).
  • 🔄 Contract engine (used):
    • ✅ Pros: price 100–180 thousand rubles, quick replacement (1–2 days).
    • ❌ Cons: risk of buying a “dead” motor, unknown mileage.
  • 🆕 New engine:
    • ✅ Pros: 1-2 year warranty, resource from scratch.
    • ❌ Cons: price 400–600 thousand rubles, long wait (if ordering from Japan).

When choosing contract engine pay attention to:

  1. Availability guarantees (minimum 6 months).
  2. Condition timing chains (must be replaced before sale).
  3. No traces block repair (welding, putty).
  4. Documents confirming mileage (preferably from a Japanese auction).

Average cost of engine replacement work Murano:

  • 🔧 Removal/installation: 30–50 thousand rubles.
  • 🛢️ Replacement of all fluids and filters: 15–20 thousand rubles.
  • 🔌 Diagnostics and tuning of the ECU: 10–15 thousand rubles.
⚠️ Attention: if you buy an engine from disassembly, be sure to check number on the block (must match the number in the PTS). Otherwise, problems may arise with registration with the traffic police.

FAQ: answers to frequently asked questions

Is it possible to drive on 92 gasoline?

Technically yes, but not recommended. Engine VQ35DE designed for AI-95, and the use of 92 gasoline leads to:

  • Reduce power by 5–7%.
  • Increased fuel consumption by 1–1.5 l/100 km.
  • Risk of detonation under high loads (e.g. when overtaking).

If there is no other choice, refuel at trusted gas stations and avoid aggressive driving.

How often should the timing chain be replaced?

Official regulations Nissan — 150 thousand km, but in practice the chain begins to stretch after 120 thousand km. Signs of wear:

  • Knock on cold start (disappears after warming up).
  • Floating idle speed.
  • Error P0011 or P0021 (displacement of valve timing).

Replacing the chain costs 40–60 thousand rubles. (with work), but if it breaks, repairs will cost 200+ thousand rubles. (bent valves).

What to do if the engine overheats?

Algorithm of actions:

  1. Stop and turn off the engine.
  2. Open the hood, but do not touch the expansion tank cap (risk of burns!).
  3. Check the antifreeze level after cooling (add only when the engine is cold!).
  4. If there is no leak, but the temperature is rising, drive a tow truck (don’t risk it!).

After overheating necessarily check:

  • Condition cylinder head gaskets (is there any oil in the antifreeze).
  • Compression in the cylinders (risk of block deformation).
What oil is best to fill in in winter?

For cold climates (below -20°C), an oil with a viscosity of 0W-30 or 0W-40 (synthetic). Recommended brands:

  • Mobil 1 0W-40 - a universal choice.
  • Idemitsu Zepro Eco Medalist 0W-20 — for new engines (mileage up to 100 thousand km).
  • Liqui Moly Top Tec 4200 5W-30 - if the winters are not too harsh.

Avoid oils with viscosity 10W-XX and higher - they thicken in the cold, which complicates cold starting.

How much does a major renovation cost?

The cost depends on the amount of work:

  • Easy repair (replacement of rings, oil seals, timing chain): 80–120 thousand rubles.
  • Medium renovation (grinding the crankshaft, replacing liners): 150–200 thousand rubles.
  • Full capital (block liner, replacement of pistons, boring): 250–350 thousand rubles.

You can save money if:

  • Buy spare parts yourself (for example, rings Nissan OEM cheaper from official dealers).
  • Look for a specialist “by acquaintance” (but check the reviews!).
