Car Nissan Sunny The 1990 model is a classic example of the reliability and simplicity for which the Japanese school of automotive engineering was valued in the late eighties. This is the generation known in the back B13, became a real hit in the secondary market due to its unpretentiousness and availability of spare parts even decades after its release. Many owners still use these cars, finding in them the perfect balance between comfort and efficiency.
Acquisition Nissan Sunny 1990 today is not just buying a vehicle, but joining the club of classic connoisseurs. The owner will have to understand the features of carburetor and injection engines, as well as assess the condition of the body, which in harsh climates may require serious intervention. The right approach to maintenance will keep this car in excellent condition for many years.
History of creation and features of the B13 generation
Generation Sunny The B13, introduced in 1990, marked a significant advance in aesthetics and aerodynamics over its predecessor. Designers abandoned angular shapes in favor of smoother lines, which reduced the drag coefficient and improved handling at high speeds. The body became more rigid, which had a positive effect on safety and driving dynamics, although it increased the weight of the structure.
Under the hood of the 1990 model, engines were installed that became the hallmark of the brand due to their durability. Particular attention should be paid to the unit GA15DE with a volume of 1.5 liters, which was distinguished by a long service life and the ability to operate on low-grade fuel, subject to regular maintenance. Depending on the sales market, the car was also equipped with more powerful engine options, including turbocharged versions for sports modifications.
The interior has retained the functionality typical of cars of that time. Ergonomics have been designed so that all controls are within the driver's reach. The instrument panel is made in a classic style with large dials that are easy to read even in bright sunlight. The quality of finishing materials is inferior to modern standards, but they are highly wear-resistant.
Technical characteristics and power units
The basis of reliability Nissan Sunny 1990 lies in its power block. Most examples on the road are equipped with in-line four-cylinder engines, which are distinguished by their simplicity of design. The absence of complex fuel injection systems in early versions allows you to carry out repairs yourself even with a minimal set of tools. However, the injection versions, which appeared closer to the middle of production, provide better environmental friendliness and smoother operation.
The transmission is represented by both manual gearboxes and automatic torque converters. A manual transmission is distinguished by precise gear selection and clutch reliability, while an automatic transmission requires more careful monitoring of the level and condition of the transmission fluid. The car's suspension is built according to the classic design: independent MacPherson strut at the front, semi-independent beam at the rear, which provides a decent level of comfort on rough roads.
- Engine GA15DE produces up to 90 horsepower with a volume of 1.5 liters
- The maximum speed for atmospheric versions is about 160-170 km/h
- Fuel consumption in the urban cycle rarely exceeds 8-9 liters per 100 km
- The vehicle's ground clearance is 155 mm, which allows it to overcome light off-road conditions.
It is important to note that the engine life directly depends on the quality of the oil and the regularity of its replacement. Ignoring this rule can lead to wear of the cylinder-piston group and the need for major repairs. The cooling system also requires attention, as overheating can be fatal for older aluminum radiators.
⚠️ Attention: Upon purchase Nissan Sunny 1990, be sure to check the compression in the cylinders. Low readings may indicate worn rings or burnt valves, which leads to costly repairs.

Weak points of the body and corrosion resistance
Body Nissan Sunny 1990, despite its strength, has a number of vulnerable points susceptible to corrosion. Under conditions of using deicing agents and high humidity, the metal begins to deteriorate quite quickly. Particular attention should be paid to the sills, wheel arches and bottom, since these are the elements that suffer primarily from the effects of road salt and moisture.
The factory anti-corrosion coating applied on the conveyor is washed out over time and loses its properties. The owner needs to regularly inspect hidden cavities and, if necessary, update the protective layer. Ignoring these procedures can result in perforation corrosion, which makes the vehicle unusable and hazardous from a safety standpoint.
Glass and seals also require attention. Over time, rubber hardens and cracks, which leads to drafts and water entering the interior. Replacing door and window seals is a simple procedure that will significantly increase the comfort of your trip in winter. Particular attention should be paid to glass washing nozzles, which often become clogged and require cleaning or replacement.
- Check the condition of the paintwork for chips and scratches
- Treat the bottom and sills with special anti-corrosion compounds
- Monitor the condition of drainage holes in doors and thresholds
- Inspect welds regularly for rust.

Control system and electronics
The electronic engine management system on 1990 models is simple, which is both a plus and a minus. On the one hand, the absence of complex control units simplifies diagnostics and repairs. On the other hand, modern diagnostic systems may not support the protocols of that time, which makes troubleshooting difficult without the use of specialized equipment or a multimeter.
The ignition system, which includes a coil, distributor and spark plugs, requires regular checking. Worn contacts in the distributor can lead to misfires and unstable engine operation at idle. Spark plugs must be replaced at least once every 20-30 thousand kilometers, using only analogues recommended by the manufacturer.
Interior electrical equipment, including headlights and instrument lighting, can also cause problems. Oxidation of contacts in connectors is a common phenomenon that leads to failure of individual components. Regular cleaning and treatment of contacts with conductive lubricant will help avoid such troubles. The generator and starter are highly reliable, but require monitoring of the brush assembly and bearings.
How to check the distributor?
To check the distributor, you need to remove the cover and inspect the contacts for carbon deposits and oxidation. If the contacts are burnt, they need to be cleaned with fine sandpaper or the entire distributor cap must be replaced. You should also check the slider for cracks.
Maintenance and replacement of consumables
Regular Maintenance Nissan Sunny 1990 is the key to its long and trouble-free operation. The oil filter and engine oil must be changed every 7-10 thousand kilometers. Using low-quality oil can lead to clogged oil passages and rapid engine wear. It is recommended to use oils with a viscosity that matches the climatic operating conditions.
The brake system requires special attention, since the safety of the driver and passengers depends on its serviceability. Brake pads and discs must be inspected at least once every 10 thousand kilometers. Worn pads can damage your brake rotors, leading to even more expensive repairs. Brake fluid should be changed every two years as it is hygroscopic and will accumulate moisture over time.
The cooling system also needs regular maintenance. Antifreeze should be changed every 40-50 thousand kilometers or every two years. Coolant loses its properties over time and can cause the engine to overheat. The radiator must be washed to remove dirt and scale, and the thermostat must be checked for functionality every time the fluid is changed.
- Engine oil: every 7-10 thousand km
- Brake fluid: every 2 years
- Coolant: every 2 years or 50 thousand km
- Air filter: every 15-20 thousand km
Before the winter season, be sure to check the condition of the battery and the charging of the generator. Old batteries may not withstand frost and discharge at the most inopportune moment.
