In 1999 Nissan Pathfinder second generation (index R50) has become one of the most popular SUVs on the world market. This model released under the platform Nissan D, combined the comfort of a full-size crossover and the cross-country ability of a classic frame SUV. Pathfinder R50 was offered with three body types: 3-door short, 5-door long and an extended version with an extended wheelbase - Pathfinder Armada (predecessor of modern Nissan Armada).

Under the hood of the car, time-tested engines were installed: gasoline VQ35DE (3.5 l, 240 hp) and diesel TD27Ti (2.7 l, 125 hp with turbine). Transmissions ranged from 5-speed manual to 4-speed automatic RE4R01A, which is still considered one of the most reliable in the line Nissan. However, despite the strength of the structure, Pathfinder 1999 there are a number of “diseases” that every owner should know about - from oil leaks to problems with the transfer case All-Mode 4WD.

Specifications Nissan Pathfinder R50 (1999)

The 1999 model range included several modifications, differing in engines, transmissions and drives. Basic versions were equipped with rear-wheel drive (2WD), but most cars came with all-wheel drive All-Mode 4WD - a system that allows you to switch between modes 2WD, 4WD Auto And 4WD Lock on the go. Below are the key parameters:

Parameter VQ35DE (petrol) TD27Ti (diesel)
Volume, l 3.5 2.7
Power, hp 240 125
Torque, Nm 328 294
Transmission 5MT/4AT 5MT/4AT
Fuel consumption (combined), l/100 km 12.5–14.0 9.5–11.0

Feature Pathfinder R50 became an independent front suspension on double wishbones and a rear multi-link (in versions with Armada - spring dependent). Ground clearance was 210 mm, and the approach/departure angles reached 32°/26°, which made the car competitive among Toyota 4Runner And Mitsubishi Pajero of that time. However it is important to consider that models with automatic transmission had a reduced load capacity - up to 500 kg versus 700 kg for manual versions.

Salon Pathfinder 1999 offered 5 or 7 seats (depending on the configuration), and in top versions LE heated leather seats, climate control and audio system were installed Bose. But even basic modifications could boast of reliable finishing and spaciousness - a rare combination for that time.

Weaknesses and typical problems

Despite the reputation of an “indestructible” SUV, Nissan Pathfinder R50 has a number of vulnerabilities that appear after 150–200 thousand km mileage Here are the key “diseases”:

  • 🔧 Oil leaks from under the valve cover - problem with all engines VQ. Rubber gaskets become tanned, and the cover bolts require regular tightening.
  • 🔥 Overheating of TD27Ti diesel engine due to a clogged radiator or thermostat malfunction. The engine is sensitive to fuel quality.
  • ⚙️ Wear of stabilizer bushings and silent blocks of the rear suspension - a sign: knocking on bumps.
  • 🔄 Problems with All-Mode 4WD transfer case: Chain drive wear or vacuum actuator malfunction.
  • 🔋 Oxidation of contacts in the fuse box, especially in models for markets with humid climates.
⚠️ Attention: If a light comes on on the dashboard 4WD and the car “does not see” all-wheel drive, do not rush to change the transfer case. Guilty in 60% of cases vacuum hose from the intake manifold to the actuator - it cracks or falls off.

Another common problem is corrosion of sills and rear arches. Nissan saved on anti-corrosion treatment, so rust appears after 5-7 years of operation in the Russian climate. The solution is annual treatment. ML-mastic or installing additional mudguards.

Engines: which one to choose and how to extend their service life

Choice between petrol VQ35DE and diesel TD27Ti depends on operating conditions. The gasoline engine is more powerful and dynamic, but is voracious (consumption in the city is up to 16 l/100 km). Diesel is more economical, but requires high-quality fuel and more often suffers from problems with the turbine Garrett T25.

VQ35DE - one of the most reliable engines Nissan, but it has weaknesses:

  • 🛢️ Oily appetite (up to 1 liter per 1000 km) after 200 thousand km - a sign of wear on the oil scraper rings.
  • 🔊 Knock of hydraulic compensators when cold - can be treated by changing the oil to 5W-40 with a high content of detergent additives.
  • 🔥 Overheating due to a clogged radiator or faulty thermostat (critical temperature - 105°C+).

For TD27Ti critical:

  • ⚡ Problems with fuel injection pump (high pressure fuel pump) - repairs cost 30–50 thousand rubles..
  • 🌀 Turbine wear after 250 thousand km — signs: black smoke, loss of power.
  • 🔋 Battery terminal oxidation — diesel is sensitive to voltage drops.
⚠️ Attention: If diesel Pathfinder started hard when hot, check injectors. Worn O-rings are often to blame - replacing them is cheaper than diagnosing the electronics.

To extend the life of your engine, follow these simple rules:

Change the oil every 7-8 thousand km (for a diesel engine - 5 thousand km) |

Use original oil filter 15208-65F0A|

Flush the fuel system every 30 thousand km (for diesel) |

Check the coolant level (once a month)|

Check compression when driving over 150 thousand km -->

Transmission: automatic vs manual

Gearboxes Nissan Pathfinder R50 are considered reliable, but each has its own nuances. 4-speed automatic RE4R01A withstands up to 300–400 thousand km with proper maintenance, but is afraid of overheating and aggressive drive. Mechanical FS5R30A easier to repair, but requires replacing the clutch every 100–120 thousand km.

Typical machine problems:

  • 🔄 Jerks when switching - a sign of wear on the clutches or solenoids.
  • 🛢️ Oil leaking from under the pan — check the gasket and magnets for chips.
  • 🔥 Overheating when towing, install an additional cooling radiator.

For mechanics it is critical:

  • ⚙️ Wear of 2nd and 3rd gear synchronizers — “crunch” when switching.
  • 🔧 Primary shaft oil seal leaking — oil gets onto the clutch.

With transfer case All-Mode 4WD There are two main problems:

  1. Wear of the front axle drive chain (typical crunch when turned on 4WD Lock).
  2. Malfunction of the vacuum actuator (the car “does not see” the four-wheel drive).
💡

If the machine starts to “kick”, try resetting the adaptations: disconnect the battery for 10 minutes, then drive 50 km in gentle mode. In 30% of cases this solves the problem without repair.

Tuning and modernization

Nissan Pathfinder R50 - an excellent platform for tuning, be it a light lift for off-road use or improving comfort. Popular destinations:

  • 🚙 Suspension: installation of lift kits Old Man Emu (+2–3 inches) or springs Tough Dog to increase clearance.
  • 🔧 Engine: chip tuning VQ35DE (up to +30 hp) or replacing the turbine with Garrett GT28 for diesel.
  • 🎨 Exterior: bumpers from Armada, LED headlights, roll bars.
  • 🔊 Audio: replacing the standard radio with Android Auto with rear view camera support.

For off-road use the following is often installed:

  • Rear locking differential ARB Air Locker.
  • Protection of the crankcase and transfer case (for example, from 4x4 Labs).
  • Off-road tires BF Goodrich KO2 or Toyo Open Country M/T.
⚠️ Attention: When installing a lift kit above 50 mm The alignment angles will need to be adjusted and the steering rods will need to be replaced. Ignoring this will result in uneven tire wear.

For urban use the following are relevant:

  • Installation xenon headlights (follow the law - lenses and washers are required!).
  • Modernization of the brake system (discs Brembo and pads Ferodo).
  • Interior noise insulation (materials StP or Bitumast).
What tuning is the most profitable?

According to statistics from owner forums, the most profitable tuning for the Pathfinder R50 is the installation gas equipment (for petrol versions). With a mileage of 30 thousand km per year, the savings on fuel cover the costs in 1.5–2 years. The second most popular is a 2-inch suspension lift with the installation of 31-32-inch tires, which improves cross-country ability without losing comfort.

Operation and maintenance: checklist for 100 thousand km

To Pathfinder R50 lasted longer, stick to the maintenance schedule. Below is the minimum set of work on the run 100 thousand km:

System Works Frequency
Engine Changing oil, filters (oil, air, fuel) Every 10 thousand km
Transmission Changing the oil in automatic/manual transmission, transfer case, axles 60–80 thousand km
Suspension Replacement of shock absorbers, silent blocks, balls 80–100 thousand km
Brakes Replacing pads, discs, brake fluid 40–60 thousand km
Cooling Flushing the radiator, replacing antifreeze, checking the pump 2 years or 40 thousand km

Pay special attention cooling system: on Pathfinder R50 The expansion tank often bursts (original - 21410-7S000). Also check the status rubber pipes — they become tanned and crack after 7–8 years of use.

Critical for automatic transmission change oil regularly (every 60 thousand km), even if the manufacturer claims a “maintenance-free” unit. Use only Nissan Matic-D or analogues (Mobil ATF 3309).

💡

The most common cause of death for a RE4R01A machine is untimely oil change. Chips in the valve body lead to jamming of the solenoids and failure of the entire box.

Prices for spare parts and cost of repairs

One of the advantages Pathfinder R50 is the availability of spare parts. Most parts are interchangeable with other models Nissan (For example, Terrano R20 or Navara D22). Below are the estimated prices for popular spare parts (2026):

Oil filter (15208-65F0A) 800–1 200 300–500 (Mann, Bosch)
Brake pads (front) 3 500–5 000 1 500–2 500 (Ferodo, Akebono)
Transfer case oil seal 1 800–2 500 800–1 200 (Corteco, SKF)
Turbine Garrett T25 (for TD27Ti) 45 000–60 000 25,000–35,000 (Chinese equivalents)
Clutch (set) 12 000–18 000 6 000–10 000 (Luk, Sachs)

The cost of repairs depends on the region and complexity of the work. For example:

  • Clutch replacement: 8–12 thousand rubles. (work) + spare parts.
  • Machine repair (replacement of clutches): 25–40 thousand rubles..
  • Replacing the timing chain (VQ35DE): 15–20 thousand rubles. (with work).

The most expensive repairs are related to:

  • 🔧 Engine overhaul (50–100 thousand rubles.).
  • 🔄 Replacing the transfer case assembly (80–120 thousand rubles.).
  • 🛠️ Body repair for severe corrosion (30–50 thousand rubles. beyond the threshold).

To save money, look for spare parts at disassembly sites (especially suspension and interior parts) or order through eBay/AliExpress (for example, Chinese analogues of turbines or electronics). However buying original consumables (oil, filters, belts) is cheaper from official dealers during promotions - the difference with the market can reach 30%.

FAQ: answers to frequently asked questions

How much does the Pathfinder R50 get on the highway?

For VQ35DE with an automatic transmission the consumption is 9.5–11 l/100 km at speed 90–110 km/h. Diesel TD27Ti consumes 7–8.5 l/100 km under the same conditions. Consumption is affected by vehicle load, tire pressure and driving style.

Can you tow a trailer on a 1999 Pathfinder?

Yes, but with restrictions: maximum trailer weight - 1.5 tons for versions with automatic and 2 tons for mechanics. Excess weight leads to overheating of the box and wear of the clutch. For towing it is recommended:

  • Install an additional automatic transmission cooling radiator.
  • Use a trailer brake unit (mandatory for weights >750 kg).
  • Check the oil level in the transfer case and axles every 5 thousand km.
What antifreeze should I put in my Pathfinder R50?

Manufacturer recommends green antifreeze based on ethylene glycol (specification Nissan L248). Suitable analogues: CoolStream A-110, Sintec Unlimited G12+. System volume - 8.5 l. You cannot mix antifreeze of different colors!
