Nissan Patrol 314 uncensored: honest analysis of the Y31 model

If you are looking for information about Nissan Patrol Y31 (314) without embellishment, we came to the right place. This model, released in 1997-2004, has become a cult among SUV enthusiasts, but behind its legendary reputation there are nuances that dealers and “rave” reviews are silent about. In this article we will look at Patrol 314 under a microscope: from engines TD42 And TB45E to gearboxes, suspension and typical “diseases” that haunt owners after 20+ years of operation.

We won't tell tales about the "unkillable Japanese" - instead you will get real data on reliability, repair costs and tuning alternatives that save your budget. If you are planning a purchase or already own Patrol 314, here you will find answers to questions that are not covered in glossy magazines. Let's start with the main thing: which engines are worth choosing and which ones to avoid.

Patrol 314 engines: which one to choose and why

Under the hood Nissan Patrol Y31 three main engines were installed: diesel TD42 (4.2 l), petrol TB45E (4.5 l) and rare RD28T (2.8 l turbo). Each of them has its own advantages and critical flaws, which appear with age. Let's figure out which engine is worth the investment and which one will turn ownership into a nightmare.

TD42 - the most popular choice among domestic owners. This naturally aspirated diesel engine is famous for its simplicity of design and service life. 500,000+ km, but only subject to timely maintenance. The main problem is cylinder head (cylinder head), which requires replacing the gasket every 100,000–150,000 km. If you ignore this procedure, the risk of coolant getting into the oil (and vice versa) increases significantly. The second weak point is injection pump (high-pressure fuel pump), which on worn-out models begins to “drive” diesel fuel into the crankcase.

Gasoline TB45E — the choice of those who don’t want to bother with a diesel engine. This motor is more powerful (200–245 hp depending on the version), but its appetite for fuel reaches 20–25 l/100 km in the city. Main problems: overheating (due to clogged radiators or a faulty thermostat) and oil starvation under prolonged loads. If you plan to drive off-road, be prepared to change the oil frequently and monitor the coolant level.

Turbodiesel RD28T - a rarity on the Russian market, but some owners praise it for its dynamics. However, this motor not intended for harsh conditions: the turbine often fails after 200,000 km, and repairs cost a lot of money. If you get caught Patrol 314 with RD28T, check the compression and condition of the intercooler - this will save nerves and money.

• 🔧 TD42: reliable, but requires careful attention to the cylinder head and injection pump.
• ⛽ TB45E: powerful, but power hungry and prone to overheating.
• 🌀 RD28T: dynamic, but expensive to repair.

Gearboxes: automatic vs manual

B Patrol 314 two gearboxes were installed: 5-speed mechanics (FS5R30A) and 4-speed automatic (RE4R01A). The mechanics are considered almost “eternal” - with careful use, they can withstand 400,000+ km without major repairs. The main thing is to follow clutch (resource 150,000–200,000 km) and change the oil on time. An automatic machine requires more careful handling.

Automatic transmission RE4R01A - weak point Patrol 314. Its resource rarely exceeds 250,000 km, and repairs cost 80,000–150,000 rubles. Main problems:

• Wear torque converter (manifested by vibrations and jerks).
• Failure solenoids (leads to kicks when switching).
• Oil overheating (if you do not change the fluid every 60,000 km).

If you buy Patrol with an automatic, be sure to check the service history of the box!

⚠️ Attention: Never tow Patrol 314 with a machine gun at a distance of more than 50 km without hanging the drive wheels. This is guaranteed to kill the box!

Gearbox type	Resource (km)	Weaknesses	Repair cost (₽)
Mechanical (FS5R30A)	400 000+	Clutch, bearings	20 000–50 000
Automatic (RE4R01A)	200 000–250 000	Torque converter, solenoids	80 000–150 000

Suspension and steering: what breaks first

Suspension Patrol Y31 built on the basis continuous bridge (front and rear), which provides excellent maneuverability, but requires regular maintenance. The most vulnerable elements:

• 🔩 Ball joints - break down every time 80,000–100,000 km.
• 🛢️ Silent blocks — rubber bushings dry out and crack (especially in the rear suspension).
• 🔧 Steering rods and ends — backlash appears after 150,000 km.
• 🚗 Shock absorbers - leak or lose effectiveness through 100,000–120,000 km.

If you are buying used Patrol 314, be sure to check the condition springs — they often sag, which leads to body roll.

Steering in Y31 — recirculation ball mechanism (without hydraulic booster in basic versions). This is a reliable system, but over time it develops play. Main problems:

• Wear worm pair (manifests itself as a “stiff” steering wheel or a knocking sound when turning).
• Leak steering rack (in versions with power steering).

Repair of the steering mechanism costs 30,000–60,000 rubles, so when purchasing, check the steering wheel play in place!

Rock the car by the wing - if the rocking lasts more than 2 seconds, the shock absorbers are dead

Check the play in the ball joints (jack up and rock the wheel)

Inspect silent blocks for cracks

Check the tie rods for play (an assistant turns the steering wheel, you are looking from the side)

Tuning Patrol 314: what really works and what is a waste of money

Owners Patrol Y31 love to tune their cars, but not all modifications are worth the investment. Let's look at the most popular destinations and their real efficiency:

1. Suspension lift (lift)

Many people put +2–3 inches to increase ground clearance and install larger wheels. However this leads to:

• Accelerated wear CV joints And cardan shafts.
• Offset toe angles, which leads to uneven tire wear.

If you need an elevator, it's better to choose soft spacers (up to +1.5 inches) and install extended shock absorbers.

2. Installation of turbine on TD42

Some owners try to "disperse" the atmospheric TD42 using a turbine. However, this motor not designed for increased loads:

• Weak piston group cannot withstand pressure.
• Replacement required injection pump to a more productive one (expensive!).
• The engine life is reduced by 2–3 times.

If you want power, it's better to consider Patrol Y61 with ZD30 or TB48DE.

3. Crankcase and bumper protection

Useful tuning for off-road:

• 🛡️ Installation metal crankcase protection (from 15,000 rubles).
• 🚙 Replacing the plastic bumper with steel (from 30,000 rubles).

These modifications they really save when driving on rocks and forest roads.

Typical problems of Patrol 314: what to look for when buying

When inspecting a used one Nissan Patrol Y31 please note the following critical moments:

1. Body corrosion

Patrol 314 suffers from rust in the following places:

• 🚗 Thresholds (especially from below).
• 🚪 Doors (bottom edges).
• 🔧 Rear suspension mounts.

If rust has eaten right through the metal, restoration will cost 50,000–100,000 rubles.

2. Electrics

Weak points:

• 🔋 Generator (often fails after 200,000 km).
• 💡 Fuse box (contacts oxidize).
• 📡 Electric drive antenna (the mechanism breaks down).

Please check the work before purchasing all electrical appliances (window lifters, heater, lights).

3. Brake system

B Patrol 314 often wear out:

• 🛑 Brake discs (especially the front ones, due to the heavy weight of the car).
• 🔧 Master brake cylinder (flows after 150,000 km).

If the brake pedal "falls" when you press it, this is a sign GTZ malfunctions or air in the system.

⚠️ Attention: If in Patrol 314 the light is on ABS, it may not only be the sensor, but also a problem with control unit (repair from 10,000 rubles).
