Feature Terrano R20 — frame structure and dependent suspension on axles. This provides excellent cross-country ability, but reduces comfort on asphalt. The car is designed to operate in harsh conditions, but requires regular maintenance.

⚠️ Attention: Diesel versions TD27T sensitive to fuel quality. The use of modern diesel with low sulfur content can lead to problems with fuel equipment.

Weaknesses and typical problems

Despite the simple design, it has Nissan Terrano 1998 There are a number of “childhood diseases”. The main problems are related to the age of the car and the specifics of its operation.

Top 5 vulnerabilities:

• 🚗 Corrosion: sills, arches, bottom - rust even with minor damage to the paintwork. Welding areas are especially vulnerable.
• ⚙️ Automatic: The automatic transmission often fails after 200 thousand km. Typical symptoms are kicking, slipping, oil leakage.
• 🔥 Turbine: on TD27T turbocharger resource is 150-200 thousand km. Signs of malfunction: smoky exhaust, loss of power.
• 🔋 Electrical: oxidation of contacts, problems with the generator, faulty sensors (especially the crankshaft position sensor).
• 🛢️ Fuel system: clogged injectors, worn fuel injection pump, leaking fuel lines.

Another common problem is wear of transfer case bearings and axle gearboxes. When driving at high speeds, a hum or vibration may occur. It is recommended to check the oil level in the axles every 30 thousand km.

⚠️ Attention: Upon purchase Terrano with a mileage of more than 250 thousand km, be sure to check the condition of the timing chain. On diesel engines, its breakage leads to bending of the valves.

TD27T engine: features and maintenance

Diesel TD27T - main trump card Terrano 1998. This motor is known for its “indestructibility”, but only with proper maintenance. Main features:

• 🔥 Turbocharging: a system with an intercooler is used, which increases reliability, but requires monitoring the condition of the pipes.
• 🛢️ Fuel equipment: mechanical injection pump Bosch VE — repairable, but sensitive to the quality of diesel fuel.
• 🔧 Block head: aluminum, prone to deformation when overheated. It is important to monitor the cooling system.

Critical points during operation:

One of the main questions is what oil to put in TD27T. Optimal choice: semi-synthetic 10W-40 or 15W-40 with permission API CF-4. It is not recommended to use synthetics due to the risk of leaks through the seals.

Typical engine faults:

Symptom	Possible reason	Solution
Black smoke from the exhaust	Air filter clogged or fuel injection pump faulty	Replace the filter, check the fuel injection pump on the stand
White smoke and increased oil consumption	Turbine worn out or cylinder head gasket burnt out	Turbine diagnostics, gasket replacement
Treble and vibration	Faulty injectors or low compression	Compression check, injector repair

Transmission: Manual vs Automatic

Choosing between manual and automatic Terrano 1998 depends on operating conditions. Mechanical box FS5R30A is considered more reliable, but has its own nuances.

Advantages of manual transmission:

• ✅ Resource up to 300 thousand km with proper maintenance.
• ✅ Easier and cheaper to repair.
• ✅ Better suited for off-road use.

Weaknesses of manual transmission:

• ❌ Wear of 2nd and 3rd gear synchronizers.
• ❌ Primary shaft seal leaks.
• ❌ Backlash of shaft bearings.

Automatic transmission RL4R01A less reliable, but more comfortable in the city. Main problems:

• 🔴 Wear of friction clutches and solenoids after 200 thousand km.
• 🔴 Overheating when towing or driving off-road.
• 🔴 Oil leaks through the shank seal.

To extend the life of an automatic transmission you must:

1. Change oil every 40-50 thousand km (use Nissan Matic-D or equivalent).
2. Avoid sudden starts and prolonged slipping.
3. Check the oil level on a warm box.

⚠️ Attention: If the automatic transmission begins to “kick” when switching from 1st to 2nd gear, this is the first sign of wear on the clutches. Replacing the clutch package will cost 15-20 thousand rubles.

Suspension and steering

Suspension Terrano R20 built according to the classical scheme: at the front - independent torsion bar, at the rear - dependent on springs. This provides excellent maneuverability, but requires regular maintenance.

Weak points:

• 🔧 Ball joints: they fail every 50-70 thousand km. The sign is a knocking sound when driving over bumps.
• 🛞 Wheel bearings: they buzz after 100 thousand km. Replacement requires a special puller.
• 🔩 Springs: they sag or break after 150 thousand km. It is recommended to replace them with reinforced ones from Patrol GR.
• 🚗 Steering rack: The oil seal is leaking or the worm gear is loose.

To check the condition of the suspension, it is enough to drive over a speed bump at a speed of 10-15 km/h. Extraneous knocks or creaks are a reason for diagnosis.

The steering is rack and pinion type with hydraulic booster. Typical problems:

Symptom	Reason	Elimination
Stiff steering wheel rotation	Low power steering fluid level or pump wear	Add liquid PSF, check the pump
Steering play	Worn steering rods or rack	Replacing rods or repairing racks
Creak when turning	Wear of boots or constant velocity joints (CV joints)	Replacing boots and lubrication of CV joints

Electrical equipment and typical faults

Electrics Nissan Terrano 1998 - one of the most vulnerable places. The main problems are related to contact oxidation, wiring wear and generator malfunctions.

Frequent breakdowns:

• ⚡ Generator: The diode bridge or voltage regulator fails. The sign is that the battery is undercharged.
• 🔋 Starter: wear of the bendix or solenoid relay. Symptom: Clicking noise when starting up.
• 💡 Lighting: Bulbs burn out or headlight sockets oxidize.
• 📡 Sensors: Most often, the crankshaft position sensor (CPS) breaks down, which makes it impossible to start.

To diagnose electrical equipment, it is useful to have a multimeter. For example, the normal voltage on the battery when the engine is running is 13.8-14.4 V. If the reading is lower, the problem is in the alternator or charging circuit.

Prevention Tips:

1. Once a year, clean the battery terminals and ground wire contacts.
2. Check the voltage of the on-board network with consumers turned on (headlights, heater).
3. Use a contact lubricant (eg Liqui Moly Kupfer-Spray) to protect the connectors.

⚠️ Attention: If after washing the engine Terrano stopped starting, check the fuses in the block under the hood. Often water gets into the mounting block, causing a short circuit.

How to check DPKV without a diagnostic scanner?

Disconnect the sensor connector and measure the resistance with a multimeter. The normal value is 500-700 Ohms. If there is no resistance or tends to infinity, the sensor is faulty.

Repair and tuning: what you can do yourself

One of the main advantages Nissan Terrano R20 is the simplicity of the design, allowing you to do many jobs yourself. Let's consider the main areas for repair and upgrade.

Repair work available in the garage:

• 🔧 Changing the oil in the engine, gearbox and axles.
• 🔩 Valve adjustment (on TD27T required every 100 thousand km).
• 🛞 Replacement of brake pads and discs.
• 🔥 Cleaning nozzles (you can use an ultrasonic bath).

Popular tuning options:

• 🚙 Suspension lift (+2-3 cm) to improve cross-country ability.
• 🔊 Installation of crankcase protection and transfer case.
• 💨 Replacing the turbine with a more efficient one (for example, Garrett TB25).

When tuning the engine TD27T often installed:

• Reinforced intercooler.
• Injectors from TD27Ti (more productive).
• Chip tuning to increase power to 120-130 hp.

For example, increasing power without strengthening the transmission will lead to rapid wear of the automatic transmission or clutch.

FAQ: answers to frequently asked questions

What is the fuel consumption of the 1998 Nissan Terrano with the TD27T diesel?

The official fuel consumption according to the passport is 9.5 l/100 km in the city and 7.5 l/100 km on the highway. Actual performance depends on driving style and engine condition:

• City (traffic jams): 10-12 l/100 km.
• Highway (90-110 km/h): 7-8 l/100 km.
• Off-road: up to 14 l/100 km (due to increased loads).

The cause of increased consumption may be a clogged air filter, faulty fuel injection pump or turbine.

Is it possible to operate the Terrano R20 on gas?

Technically install HBO on TD27T maybe, but it's highly not recommended. Diesel engines are not adapted to run on gas, and conversion to propane-butane requires complex modifications to the power supply and ignition systems (which are not available on diesel engines).

For petrol version GA16DE installation of 2nd or 4th generation gas equipment is acceptable, but the savings will be minimal due to the small engine volume.

What kind of oil should I pour into the transfer case and axles?

For transfer cases and axle reducers Nissan recommends gear oil class GL-5 with viscosity 80W-90 or 75W-90. Optimal options:

• Castrol Syntrax Universal Plus.
• Liqui Moly Hypoid-Getriebeoil TDL.
• Mobil Mobilube GX 80W-90.

Oil volume:

• Transfer case: 1.0 l.
• Front axle: 1.5 l.
• Rear axle: 2.0 l.

Replacement interval - every 60 thousand km or every 3 years.

How to check the center differential lock?

Differential lock on Terrano R20 activated by a button on the gearshift lever (indicated by a red symbol). To check its functionality:

1. Start the engine and park the car on a level surface.
2. Turn on the lock (the indicator on the panel should light up).
3. Try to drive off - if the lock is working, the car will “bounce” when you try to turn the wheels in different directions.

If the lock does not turn on, check:

• fuse F10 (10A) in the mounting block.
• Condition of the electromagnetic clutch on the transfer case.
• Integrity of wiring from the button to the transfer case.
