Under the hood Nissan Pathfinder In the third generation, gasoline power units are most often found. The most common is the naturally aspirated engine. VQ40DE volume 4.0 liters. This engine has high power of 266 horsepower and good traction at low speeds, which is critical for a heavy body.
The engine is paired with a 5-speed automatic transmission RE5R05A. It is reliable with timely oil changes, but is sensitive to overheating. If you plan to use your vehicle to tow trailers, you need to monitor the transmission temperature.
- Engine VQ40DE requires the use of high-quality oil with tolerances of at least 5W-30.
- Automatic RE5R05A has a resource of about 200,000 km, subject to maintenance every 60,000 km.
- The fuel injection system is sensitive to the quality of gasoline; it is recommended to refuel at proven gas stations.
Many drivers note that acceleration to 100 km/h takes about 8-9 seconds, which is an excellent indicator for a full-size SUV. However, fuel consumption in the urban cycle can reach 18-20 liters per 100 km, which should be taken into account when planning your budget.
⚠️ Attention: If a knock appears in the area of hydraulic compensators or valve lifters, you must immediately check the clearances. Ignoring this problem can lead to burnout of valves and major engine repairs.
There is also a version with a diesel engine YD25DDTi with a volume of 2.5 liters, which is less common on the Russian market, but has high torque. This engine requires careful maintenance of the fuel system and cooling system.
- Petrol 4.0 V6
- Diesel 2.5 Turbo

- I have a different modification
The 4.0 V6 petrol engine is the most balanced choice in terms of power, reliability and cost of ownership for this car.
All-wheel drive and chassis
All-wheel drive system On-Demand in the third generation Pathfinder works automatically, connecting the rear axle when the front one slips. This solution saves fuel on dry asphalt and provides confident traction on slippery roads.
Owners note that the system copes well with light off-road conditions, snow and mud, but is not intended for extreme off-road use. The absence of a reduction gear in some trim levels limits the vehicle's capabilities in the mountains or on serious off-road conditions.
- Switching between 2WD, 4WD Auto and 4WD Lock modes is done using a button on the instrument panel.
- The rear differential is equipped with an electronic lock (on certain trim levels), which improves cross-country ability.
- The front suspension is independent, MacPherson type, which provides a soft ride, but reduces the resource when driving frequently on bad roads.
The rear multi-link suspension provides stability at high speeds, but requires regular checking of the bushings and control arms. With a mileage of over 100,000 km, it is often necessary to replace shock absorbers and springs to restore body geometry.
⚠️ Attention: In 4WD Lock mode, the system forcibly locks the center differential. Use this mode only at speeds up to 80 km/h and only on slippery surfaces to avoid damaging the transmission.
When operating in winter, you should pay attention to the condition of the CV joint boots. Their rupture can lead to leaching of lubricant and failure of the axle shafts, which entails an expensive replacement.
☑️ Checking the chassis before a winter trip
Use in harsh environments
For Russian realities Nissan Pathfinder III requires some preparation. Corrosion is one of the main enemies of this car, especially in regions where reagents are used. Body panels, sills and arches require regular inspection and anti-corrosion treatment.
The cabin heating system works efficiently, but warming up the engine in severe frosts can take a long time. It is recommended to install a preheater or use high-quality engine insulation to quickly reach operating temperature.
Particular attention should be paid to electrics. Moisture can get into the sensor connectors, causing errors on the dashboard and malfunctioning electronic systems. Regularly cleaning contacts and treating them with a moisture spray will help avoid problems.
- Check the tightness of door and glass seals to prevent fogging of the optics and interior.
- Replace the air filter more often than recommended if you operate the vehicle in dusty conditions.
- Monitor the condition of the alternator belt, as its breakage in winter can lead to rapid discharge of the battery.
Many owners note that replacing standard spark plugs with iridium spark plugs allows you to extend the service interval and improve engine stability in cold weather.
Features of starting in cold weather
If the engine does not start for a long time, do not try to turn the starter for more than 10 seconds. Let it cool for 2-3 minutes to avoid overheating the starter and draining the battery. Check the battery charge and the condition of the fuel filter, as paraffin may form in diesel versions.
To protect the paintwork in winter, use liquid glass or ceramic coating, which will create an additional barrier against reagents and salt.
Comparison table of technical characteristics
To better understand the capabilities of the car, it is useful to compare the main parameters of the different versions. Below is a table with data for the most common modifications on the market.
