Nissan Avenir (known in some countries as Ernessa) 1998 model year is a compact minivan that has become popular due to its practicality and reliability. Released during the heyday of Japanese minivans, it combined a spacious interior, economical engines and ease of maintenance. However, like any car with more than 25 years of history, Avenir W10 (second generation) has its own characteristics that are important to consider when purchasing.

This model is often found on the secondary market in two modifications: with front-wheel drive or all-wheel drive, as well as with gasoline engines of 1.8 or 2.0 liters. But not everything is so simple: some examples were equipped with turbocharged engines, while others were equipped with a CVT, which requires special attention during diagnosis. In the article we will analyze technical specifications, weak points, recommendations for selection and operating nuances that will help you avoid costly mistakes.

Technical specifications Nissan Avenir (Ernessa) 1998

Nissan Avenir W10 1998 was offered with several options for powertrains, transmissions and drives. Basic versions were equipped with naturally aspirated engines of the series SR, and the top ones are turbocharged SR20DET. Below are the key parameters:

  • 🔧 Engines:
    • SR18DE — 1.8 l, 125 hp (atmospheric)
    • SR20DE — 2.0 l, 140–150 hp (atmospheric)
    • SR20DET — 2.0 l, 205 hp (turbo)
  • ⚙️ Gearboxes:
    • 5-speed manual transmission
    • 4-speed automatic (RE4F04A)
    • CVT (select markets only)
  • 🚗 Drive: front (FF) or four-wheel drive (4WD)
  • ⛽ Fuel consumption: from 8.5 to 12 l/100 km (depending on the engine and transmission)

A special feature of the model is independent suspension of all wheels (front - MacPherson type, rear - multi-link), which ensured good handling for a minivan. However, over time, suspension components wear out, and replacing them can cost a fortune. It is also worth noting that Avenir equipped power steering And air conditioning even in basic trim levels, which was rare for the late 90s.

Parameter SR18DE (1.8) SR20DE (2.0) SR20DET (2.0 Turbo)
Power, hp 125 140–150 205
Torque, Nm 153 180–185 275
Fuel consumption (combined), l/100 km 8.5–9.5 9.5–11 11–12
Recommended fuel AI-92 AI-92 AI-95/98

Important: Turbocharged versions of the SR20DET require special attention to the cooling system and oil quality - if maintenance is not timely, the turbine life can be reduced to 100–150 thousand km.

Weaknesses and typical problems

Despite the reliability of the platform, Nissan Avenir 1998 has several “diseases” that appear with age. Here are the most common:

  • 🔥 Engine problems:
    • Oil leaks through valve cover And crankshaft rear oil seal (typical for all SR series motors).
    • Wear timing chains on runs over 200 thousand km (if the valve breaks, the valve bends!).
    • Overheating SR20DET due to a clogged radiator or faulty thermostat.
  • 🔧 Transmission:
    • Oil leaks in Automatic transmission RE4F04A (the shank seal is often the culprit).
    • Clutch wear on manual transmissions after 150–180 thousand km.
    • Problems with the variator (if installed) - the resource rarely exceeds 200 thousand km.
  • 🚗 Chassis:
    • Wear stabilizer struts And bushings (knocks when driving over bumps).
    • Shock absorber leaks (the original ones last ~150 thousand km).
    • Backlash in ball joints And steering rods.
  • ⚡ Electrical:
    • Oxidation of contacts in the fuse box (leads to “glitches” of devices).
    • Failure generator or starter (typical for cars with mileage over 250 thousand km).
    • Problems with central locking (micro switches in doors are often to blame).
⚠️ Attention: Upon purchase Avenir with a mileage of more than 200 thousand km, be sure to check the compression in the cylinders. Norm for SR20DE - not lower than 11–12 bar in each cylinder. If the difference between the cylinders exceeds 1 bar, the engine requires repair.

How to choose a used Nissan Avenir (Ernessa) 1998

Upon purchase Nissan Avenir The 1998 model has several key aspects to pay attention to. Firstly, check car history: whether he was in an accident, how often he underwent maintenance, whether the oil was changed regularly. Secondly, inspect the body for corrosion — rust often appears on arches, sills and suspension mounting points.

Pay special attention to:

☑️ Checklist when inspecting Nissan Avenir 1998

Done: 0 / 5
  • 🔍 Engine:
    • Isn't it blue smoke from the exhaust pipe (indicates oil burner).
    • How quickly the engine warms up (should reach operating temperature in 5–7 minutes).
    • Are there any extraneous noises (knocking of hydraulic compensators, timing chains).
  • 🔧 Gearbox:
    • On an automatic transmission, check the smoothness of the shifts (jerks indicate problems with the solenoids).
    • On a manual transmission, make sure there is no crunching noise when shifting gears.
  • 🚗 Suspension:
    • Carry out a “swing” test - if the car rocks for a long time, it’s time to change the shock absorbers.
    • Check for play in the steering.

If you are considering the version with SR20DET, be sure to check:

  • Condition turbines (is there any play, how quickly the pressure builds up).
  • Integrity intercooler and pipes.
  • Are there any traces detonation (knock of “fingers” when pressing the gas sharply).
⚠️ Attention: Turbocharged Avenir were often subjected to tuning, which could reduce engine life. If the seller cannot provide a history, it is better to refuse the purchase.
💡

When inspecting, pay attention to the condition of the side members - if they are rusty, restoring the body may cost more than the car itself is worth.

Maintenance and repair: what you need to know

Contents Nissan Avenir 1998 in working order requires regular maintenance. Here are the main recommendations:

  • 🛢️ Changing oil and filters:
    • Engine oil - every 7–10 thousand km (for turbo engines - every 5 thousand km).
    • Automatic transmission oil - every 60 thousand km (complete replacement with flushing).
    • Fuel filter - every 40 thousand km.
  • ⚙️ Regulatory work:
    • Timing Belt/Chain - Each 100–120 thousand km.
    • Spark plugs - every 30 thousand km (for turbo versions - iridium).
    • Brake pads/discs - each 50–70 thousand km.
  • 🔧 Diagnostics:
    • Compression check - once every 100 thousand km.
    • Suspension diagnostics - once every 20 thousand km.

For SR20DET critical to use high quality synthetic oil (For example, 5W-40 or 10W-40 with approval for turbo engines). It is also recommended to install oil cooler, if it is not there from the factory, it will extend the life of the turbine.

What to do if the engine starts to “eat” oil?

If oil consumption exceeds 1 liter per 1000 km, the reasons may be the following:

1. Wear of valve stem seals (typical for runs over 200 thousand km).

2. Occurrence of piston rings (requires decoking or capitalization).

3. Leakage through seals or gaskets.

As a temporary measure, additives can be used to restore the elasticity of rubber seals, but this will not solve the problem long-term.

For Automatic transmission RE4F04A important:

  • Use only original oil Nissan Matic-D or its analogues (Idemitsu ATF Type-J).
  • Avoid sudden starts and towing heavy trailers.
  • At the first sign of jerking or delays when switching, immediately go for diagnostics.

Tuning and modernization

Nissan Avenir - a popular base for tuning, especially in the version with SR20DET. Here are some areas for modernization:

  • 🏁 Engine:
    • Installation larger intercooler (for example, from Nissan Silvia S14).
    • Replacing the turbine with Garrett T28 or T3/T4 (will require modification of the exhaust system).
    • Chip tuning (ECU firmware for increased boost pressure).
  • 🚗 Suspension:
    • Installation TEIN stands or KYB to improve handling.
    • Replacing springs with stiffer ones (for example, Tanabe NF210).
  • 🎨 Exterior:
    • Installation of body kits from Nissan Primera P11 (suitable for fastenings).
    • Window tinting and LED headlight installation.

However, before tuning it is worth assessing the feasibility of the investment. For example, major renovation SR20DET with the installation of forced parts can cost 150–200 thousand rubles, which is comparable to the cost of the car itself. If the goal is simply to improve the dynamics, it is enough to confine yourself to flashing the ECU and installing exhaust system 4-2-1.

⚠️ Attention: If the power increases by more than 30% from stock, it will be necessary to strengthen the braking system (for example, install calipers from Nissan Skyline R33).
