Nissan Murano with 3.5 V6 engine: everything the owner needs to know

Engine VQ35DE 3.5 liter volume - the heart of the second and third generations Nissan Murano, which has earned a reputation as a reliable but maintenance-intensive unit. This motor, developed in the early 2000s, has become one of the most popular in the line Nissan thanks to the balance of power and efficiency. However, it has its own “pain points” that are important to know about before purchasing or during operation.

In this article we will look at technical specifications engine, typical problems and malfunctions, and also give practical recommendations on maintenance and tuning. We will pay special attention to issues of service life, oil consumption and the selection of spare parts - topics that most often concern owners Murano Z51 And Z52.

Technical specifications of VQ35DE in Nissan Murano

Engine VQ35DE belongs to the family VQ - a series of V-shaped six-cylinder engines that Nissan has been producing since 1994. Version for Murano has an aluminum cylinder block, variable valve timing system CVTCS on the intake shaft and electronic throttle Drive-by-Wire. Here are the key parameters:

• 🔧 Volume: 3498 cm³
• 🔥 Power: 234–265 hp (depending on year and market)
• ⚡ Torque: 328–336 Nm at 2800–4800 rpm
• ⛽ Fuel: AI-95 (recommended), AI-92 is allowed
• 📏 Dimensions (D×S): 95.5×81.4 mm
• 🔄 Compression Ratio: 10.3:1

Paired with VQ35DE on Murano a continuously variable transmission was installed CVT RE0F10A (until 2014) or classic “automatic” Jatco JF011E (in some markets). The motor complies with environmental standards EURO-4 And EURO-5, and its weight is about 160 kg - relatively light for a V6.

Interesting fact: this engine was also installed on Nissan 350Z, Infiniti G35 And Pathfinder R51, but in Murano it is tuned to be more "civilian" in nature - with an emphasis on smooth operation and economy.

Engine life: how long will the VQ35DE last?

Official engine resource VQ35DE from Nissan amounts to 250–300 thousand km, but with proper maintenance, many copies exceed the mark of 400+ thousand km. Key factors affecting durability:

• 🛢️ Oil quality and change intervals - critical for timing chain drive.
• 🔥 Overheating — even a single case reduces the resource by 20–30%.
• ⚡ Riding style — frequent loads at high speeds accelerate wear.
• 🔧 Timely replacement of consumables (candles, filters, belts).

According to statistics from service centers, most breakdowns after 200 thousand km are associated with timing chain wear, the occurrence of the rings or problems with the phase change system. For example, on runs over 300 thousand km, replacement is often required CVTCS-solenoids and cleaning of oil channels.

Mileage, thousand km	Typical work	Cost, ₽ (approximately)
100–150	Replacing the timing chain, variator oil, spark plugs	40 000–60 000
200–250	Cleaning the throttle, replacing ignition coils, CVTCS diagnostics	25 000–45 000
300+	Overhaul (boring, replacement of rings, valves), replacement of variator	150 000–300 000

⚠️ Attention: If the engine begins to “eat” oil (consumption > 500 ml per 1000 km), this is a signal about critical wear of oil scraper rings or valve seals. In this case, flushing and additives will not help - an autopsy is required.

Common problems and malfunctions

Despite the reliability VQ35DE has several “childhood diseases” that appear with age. Here are the most common:

1. Timing chain stretching

The problem occurs after 150–200 thousand km and appears as knocking when cold or jumping revs. The reason is wear of the plastic dampers and tensioners. If you ignore the symptoms, the chain may jump, resulting in meeting of valves with pistons (and this is a major overhaul).

2. Oil leaks

Weaknesses - crankshaft rear oil seal, valve cover And oil seals. Leaks often appear after 150 thousand km and get worse when using low-quality oil. For example, a leaky crankshaft oil seal can flood the clutch (on models with automatic transmission, the torque converter), which will lead to slipping.

3. Problems with the CVTCS system

The solenoids and variable valve timing clutches become clogged with deposits, causing the engine to lose power and appear vibration at idle or error P0011/P0021. Cleaning or replacing the oil with a higher quality one often helps (for example, Mobil 1 5W-40).

How to check CVTCS without diagnostics?

If, when you sharply press the gas at 2000-3000 rpm, a metallic clang is heard, and then the engine “picks up” - this is a sign of a jammed phase shifter clutch. In this case, you need to urgently go for diagnostics, since ignoring the problem leads to destruction of the camshaft.

4. Oil consumption

Normal consumption for VQ35DE - up to 300 ml per 1000 km. If the engine “eats” more, the reasons may be:

• 🔥 Worn oil scraper rings (blue smoke appears during gas changes).
• 🛢️ Stuck piston rings (compression drops, oil goes into the combustion chamber).
• 🔧 Leaky valve seals (oil flows through spark plug wells).

⚠️ Attention: Using oil with viscosity 5W-30 instead of recommended 5W-40 accelerates wear of the timing chain and increases oil consumption due to waste. This is due to lower oil film strength at high loads.

Maintenance: what to change and when

Compliance with maintenance regulations is the key to a long life VQ35DE. Here are the key points:

1. Changing oil and filters

Interval - every 7–10 thousand km (or once a year). Recommended oils:

• 🛢️ Nissan Strong Save X 5W-40 (original).
• 🛢️ Mobil 1 ESP 5W-40 (for turbocharged ones, but also suitable for naturally aspirated ones).
• 🛢️ Liqui Moly Top Tec 4200 5W-40 (cleans deposits well).

Engine oil volume - 4.8 liters (with filter replacement). Important: after changing the oil, avoid high loads for the first 500 km so that the new oil is evenly distributed throughout the system.

2. Timing chain

Official regulations - every 150 thousand km, but in practice it is better to reduce the interval to 120 thousand km, especially if the car is used in the city. Replacement kit includes:

• 🔗 Timing chain (Nissan 13028-4M51A).
• 🔧 Tensioners and dampers (Nissan 13070-4M500, 13085-4M500).
• 🔄 Pump (it is recommended to change along with the chain).

3. Spark plugs

Candles serve 60–80 thousand km, but their condition needs to be checked every 30 thousand km. Optimal choice:

• ⚡ NGK PLFR5A-11 (original for Murano).
• ⚡ Denso FK16HR11 (analogue, a little cheaper).

When replacing spark plugs, be sure to check gap - he must be 1.1 mm. If the gap is larger, the engine will stall at idle.

Tuning and modifications: is it worth upgrading the VQ35DE?

Engine VQ35DE has good potential for tuning, but the approach must be balanced. Here are the main directions:

1. Software chip tuning

Reflashing the ECU allows you to increase power up to 280–300 hp without mechanical modifications. However, there are nuances:

• ⚡ After chipping, the load on variator (if it exists), which reduces its resource.
• ⛽ Fuel consumption increases by 10–15%.
• 🔧 Replacement required exhaust manifold (the standard one “chokes” the engine).

2. Mechanical tuning

For a serious increase in power (up to 350+ hp) you will need:

• 🔥 Installation compressor (For example, Eaton M90) or turbines (but it is difficult and expensive).
• 🔧 Replacement camshafts (For example, Tomei or JUN).
• ⛽ Strengthening the fuel system (injectors Nismo 370Z, fuel pump Walbro 255).

Important: any tuning requires braking system reinforcement (for example, installing calipers from 350Z) and suspension upgrades, since standard components are not designed for increased loads.

Comparison with other Nissan engines

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

Parameter	VQ35DE (3.5)	VQ25DD (2.5)	VQ37VHR (3.7)	MR20DD (2.0)
Power, hp	234–265	170–190	310–330	140–150
Resource, thousand km	300–400	250–300	250–350	200–250
Fuel consumption, l/100 km	10–12 (city)	9–11	12–14	8–10
Typical problems	Timing chain, CVTCS	Oil leaks, vibrations	Problems with VVEL, oil consumption	Chain stretch, turbine

Conclusion: VQ35DE — the optimal choice for those who appreciate balance of power and reliability. It is easier to maintain than VQ37VHR, and more dynamic than VQ25DD. However, if you need an economical crossover, you should take a closer look at Murano with MR20DD (2.0 turbo).

Choosing between Murano with 3.5 and 2.5: which is better?

Often found on the secondary market Murano like with VQ35DE, so with VQ25DD (2.5 liters). Which option is preferable?

• ⚡ Dynamics: 3.5 accelerates to 100 km/h in 7.5–8.5 sec, and 2.5 - for 9.5–10.5 sec.
• ⛽ Fuel consumption: 3.5 “eats” 1–2 liters more in the city, but on the highway the difference is minimal.
• 💰 Cost of ownership: 2.5 is cheaper to maintain (less oil, no problems with the timing chain), but less reliable.
• 🔧 Resource: 3.5 lasts longer with proper care.

If you care comfort and reliability, choose 3.5. If the priority is savings on fuel and taxes, you can consider 2.5, but be prepared for more frequent visits to the service.

FAQ: Frequently asked questions about the VQ35DE engine

Is it possible to drive on 92 gasoline?

Officially Nissan recommends AI-95, but the engine is adapted for AI-92. However, when using 92:

• Power decreases by 5–7%.
• Fuel consumption increases by 3–5%.
• The risk of detonation increases at high loads.

If there is no alternative, you can temporarily refuel with 92, but not permanently.

How often should you check the oil level?

Ideally - every 1000 km, especially if the car's mileage is more than 150 thousand km. VQ35DE prone to “oil guzzling”, and a critically low level can lead to rotation of the liners (and this is a major overhaul).

Check the oil for hot engine 5–10 minutes after stopping, when it drains into the pan.

What to do if the check light comes on with code P0300?

Error P0300 (“multiple misfires”) in VQ35DE most often associated with:

• 🔥 Faulty spark plugs or ignition coils.
• 🛢️ Air leaks through cracks in the intake manifold.
• ⚡ Clogged nozzles (needs ultrasonic cleaning).

First check the spark plugs and coils, then the compression. If the problem persists, have the fuel system diagnosed.

How much does a VQ35DE overhaul cost?

The cost depends on the amount of work:

• 🔧 Easy overhaul (replacement of rings, seals, valves) - 80 000–120 000 ₽.
• 🔥 Complete overhaul (boring the block, replacing liners, grinding the cylinder head) — 150 000–250 000 ₽.
• 💰 Contract engine (used from Japan) — 120 000–180 000 ₽.

Advice: if the cylinder block is in good condition, it is cheaper to do a major overhaul than to buy a contract engine with an unknown history.

Is it possible to install gas on the VQ35DE?

Technically you can, but with reservations:

• ⚡ Will be required ignition adjustment (OZ needs to be reduced by 2–3°).
• 🛢️ Oil consumption will increase by 20–30% due to drier gas combustion.
• 🔧 The service life of valves and seats will be reduced by 15–20%.

If you decide to use HBOT, choose generation 4+ with lambda probe decoys and be sure to install ignition timing variator.
