Windshield <em>Nissan Sunny FB15</em>: how to choose, replace and save

Nissan Sunny FB15 is a popular sedan that is still actively used on the roads of the CIS due to its reliability and unpretentiousness. However, even such time-tested cars have a weak spot - windshield. Cracks, chips and clouding not only spoil the appearance, but also directly affect the safety of the driver. In this article we will look at everything you need to know about windshields for Sunny FB15: from original articles to the nuances of self-replacement.

Model feature FB15 (2010–2017) - a non-standard glass shape with a bend in the lower part, which complicates the selection of analogues. Many car owners encounter problems when purchasing cheap replacements: poor fit, whistling at speed, or distorted vision through tinting. We analyzed the 2026 market, interviewed service station foremen and collected current data to help you avoid common mistakes.

Original windshield Nissan Sunny FB15: articles and features

Factory glass for Sunny FB15 produced by the company AGC (Asahi Glass Co.) is a Japanese supplier known for high quality auto glass. Original article: 28510-BM40A (without rain sensor) or 28510-BM40B (with sensor). These glasses have:

• 🔹 Thickness 4.76 mm (standard for most Japanese sedans)
• 🔹 Greenish tint (reduces interior heating by 30–40%)
• 🔹 Laminated structure (triplex: two layers of glass + PVB film)
• 🔹 DOT marking (compliance with American safety standards)

An important nuance: since 2014, glass with infrared reflective coating (labeling IR-Cut). They provide better protection from solar radiation, but cost 15–20% more. You can check the presence of IR coating using a UV flashlight: the original will glow purple around the edges.

⚠️ Attention: On the market there are often counterfeits of the original with the article number 28510-BM400 (extra zero at the end). Such glasses have worse optics and may crack during installation due to poor-quality adhesive layer.

Article	Manufacturer	Features	Average price (2026)
28510-BM40A	AGC (Japan)	Without rain sensor, standard triplex	18 000 – 22 000 ₽
28510-BM40B	AGC (Japan)	With rain sensor, IR-Cut coating	24 000 – 28 000 ₽
28510-4M000	NSG/Pilkington	Analogue for the European market, thickness 4.5 mm	15 000 – 18 000 ₽
28510-BM401	FYG (China)	Budget option, often comes with defects around the edges	8 000 – 12 000 ₽

Windshield analogues: what to choose instead of the original?

Original glass from AGC ideal for fitment, but their high cost forces many to look for alternatives. The main rule when choosing an analogue is to check bending geometry at the bottom (at Sunny FB15 there is a characteristic "ledge"). The best substitutes in terms of price/quality ratio:

• 💎 NSG/Pilkington (article 28510-4M000) - European manufacturer, supplier for Renault-Nissan. Features a slightly darker shade but is fully compatible with the original mirror bracket.
• 💎 Saint-Gobain Sekurit (article 765487) - French glass with improved acoustics (no whistles at speed even at 140 km/h). Suitable for machines with system Around View Monitor.
• 💎 BOS (Belgium) - a budget option with good optics, but requires mandatory testing for light transmission (sometimes you come across batches with a yellow tint).

Critical point: cheap Chinese glass (for example, FYG or BENSON) often have distorted geometry in the rear view mirror mounting area. This leads to vibrations on uneven roads and rapid peeling of the tint. If your budget is limited, it is better to consider used originals from Japan (they can be found at salvage yards for 10,000–14,000 rubles).

When replacement is required: criteria and risks of delay

Many car owners drive with cracks for years, unaware of the hidden dangers. According to traffic police statistics, 23% of traffic accidents are fatal occur due to poor visibility through a damaged windshield. For Nissan Sunny FB15 The following defects are considered critical:

• 🚨 The crack is longer than 10 cm, even if it is not in the driver’s line of sight (risk of spreading due to temperature changes).
• 🚨 Chips more than 3 mm deep (weaken the glass structure by 5-7 times).
• 🚨 Cloudiness or “lens effect” in the upper part (a sign of triplex delamination).
• 🚨 Damage in the area where the mirror or rain sensor is attached (can damage the electronics).

Delayed replacement is fraught not only with a fine (under Part 1 of Article 12.5 of the Code of Administrative Offenses of the Russian Federation - 500 ₽), but also with more serious problems:

⚠️ Attention: B Sunny FB15 windshield is part body power structure. In the event of an accident, it must withstand a load of up to 1.5 tons, holding the roof. A crack in the top reduces this strength by 60–70%, which can lead to deformation of the interior if it rolls over.

Self-replacement: step-by-step instructions and tools

Replacing the windshield with Sunny FB15 refers to work of medium complexity. With experience and the right tools, this can be done in your garage in 3-4 hours. You will need:

• 🔧 New glass (check the package: there must be moldings and clips).
• 🔧 Adhesive sealant (we recommend 3M Urethane or SikaTack).
• 🔧 Caulking gun with a pressure of 4–6 bar.
• 🔧 String or wire for cutting off old glue (diameter 0.5–0.7 mm).
• 🔧 Suckers (minimum 2 pieces with a loading capacity of 20 kg each).

Step-by-step algorithm:

1. Remove the windshield wipers, plastic trims under the windshield and rear view mirror (disconnect the rain sensor connector, if equipped).
2. Carefully cut away the old caulk with a string, starting from the top corner. Movements should be smooth, without jerking.
3. Clean the seat from any remaining adhesive and degrease the surface. white spirit.
4. Apply new sealant to the body frame (layer thickness 8–10 mm). Don't skimp - this is a guarantee of tightness.
5. Install the glass with a helper, starting from the bottom. Use suction cups for a precise fit.
6. Secure the glass with masking tape for 12–24 hours (time for the glue to cure).

The most common mistake is incorrect glass alignment. If it is offset even by 3-5 mm, this will lead to uneven pressure on the sealant and leaks during rain. To check, use a laser level or pre-marked marker.

What to do if, after replacement, a whistle appears at speed?

Whistling at speeds over 90 km/h is usually caused by two reasons:

1) Loose fit of moldings - check them around the entire perimeter, especially in the corners. Sometimes additional sizing with double-sided tape helps.

2) Glass seal defect — on budget analogues, the rubber seal may be thinner than the original. Solution: buy a separate seal from AGC (article 28525-BM400) and replace it.

Service replacement cost: where is it cheaper and what to pay attention to

Windshield replacement prices for Nissan Sunny FB15 in 2026 vary from 3,000 to 12,000 rubles depending on the region and type of service station. Average prices:

Service type	Cost of work (₽)	Pros	Cons
Official dealer Nissan	8 000 – 12 000	1 year warranty, original materials	Expensive, long wait for an appointment
Specialized auto glass center	4 000 – 7 000	Fast, experienced craftsmen, 6 month warranty.	They may impose expensive glue
Universal service station	3 000 – 5 000	Low price, negotiable	Risk of poor installation
Mobile master	5 000 – 8 000	Will come to your home, convenient	Limited tool, no warranty

What you should pay attention to when choosing a service:

• 🔍 Type of glue used - cheap craftsmen often save on sealant by using low quality polyurethane compounds, which lose elasticity after a year.
• 🔍 Availability of vacuum suction cups — without them it is impossible to carefully install glass without microcracks.
• 🔍 Warranty — bona fide centers provide a guarantee not only on the glass, but also on the tightness of the seam.

⚠️ Attention: In Moscow and St. Petersburg, a fraudulent scheme is widespread when services install used glass under the guise of new. You can check this by DOT marking — on original glasses it is engraved with a laser, on used ones it is often erased.

Tinting and additional protection: do's and don'ts

Windshield tinting on Nissan Sunny FB15 - the topic is controversial. According to GOST 32565-2013, the light transmission of the windshield must be at least 70%. However, many car owners install a film with a coefficient of 75–80%, which is visually almost invisible, but provides protection from UV rays.

Recommended options:

• 🌞 Film LLumar ATR 70% — transmits 70% of light, blocks 99% of UV rays. Does not distort the view, suitable for cars with a rain sensor.
• 🌞 3M Crystalline 70% — premium film with a metallized layer, does not interfere with the operation of radar detectors.
• 🌞 SunTek CIR — a budget option with good thermal protection (reduces interior heating by 25%).

What you should absolutely not do:

• ❌ Gluing film with a coefficient below 70% - a fine of 500 ₽ (part 3.1 of article 12.5 of the Administrative Code).
• ❌ Use metallized films - they block GPS and mobile communications signals.
• ❌ Tinting the rear view mirror mounting area - this worsens the view and may cause a refusal to undergo maintenance.

For additional protection against chipping, you can install armored film (For example, XPEL Ultimate or LLumar Platinum). It is transparent, but can withstand impacts from stones at speeds of up to 120 km/h. The cost of wrapping a windshield is from 15,000 ₽.

Common problems after replacement and how to avoid them

Even after a professional windshield replacement Sunny FB15 Unpleasant surprises may arise. Here are the most common of them and methods of prevention:

• 💧 Water leaks - usually appear 1-2 weeks after replacement. Reason: poor quality sealant or non-compliance with application technology. Solution: re-glue the glass using SikaTack Drive (special glue for emergency repairs).
• 🔊 Whistle at speed - occurs due to a loose fit of the moldings or deformation of the seal. Solution: apply silicone grease around the perimeter or replace the seal.
• 📱 The rain sensor does not work - often happens if the technician forgot to connect the connector or damaged the wiring. Solution: check the contacts with a multimeter.
• 👓 Review Distortion - a sign of poor quality glass or improper installation. Solution: only replacement with the original or a proven analogue.

To minimize risks, after replacement:

1. Do not wash the car for 48 hours (the sealant must cure completely).
2. Avoid sudden temperature changes (do not park the car immediately after replacement in a heated garage in winter).
3. Check the operation of the wipers - they should not cling to the edge of the glass.

How to check the quality of glass installation?

2-3 days after replacement, perform the test:

1. Visual inspection — the sealant must be uniform around the entire perimeter, without bubbles.

2. Leak test — direct a stream of water from the hose to the junction of the glass and the body. There should be no leaks.

3. Vibration test — drive on an uneven road. Extraneous noise or rattling indicates a poor fit.

FAQ: answers to frequently asked questions

Is it possible to drive with a crack in the windshield? Nissan Sunny FB15, if she is not in the viewing area?

Technically possible, but highly undesirable. A crack weakens the structure of the glass, and in the event of an accident it can crumble without holding the roof. In addition, even a small crack will grow over time due to vibrations and temperature changes. According to statistics, 80% of cracks longer than 5 cm lead to complete glass replacement within a year.

How much does it cost to replace a windshield with a rain sensor?

The cost depends on the type of glass and service:

• Original AGC + work: 30,000 – 35,000 ₽.
• Similar to NSG/Pilkington + work: 22,000 – 26,000 ₽.
• Used original + work: 15,000 – 18,000 ₽.

Important: when replacing glass with a rain sensor, the technician must reconfigure the system Auto Wipe via a diagnostic scanner (for example, Launch X431). Without this, the wipers may work spontaneously.

Can I repair a chip on my windshield myself?

Yes, but only if the chip is no larger than a coin and is not in the driver’s field of vision. For repair you will need:

• Chip repair kit (e.g. Permatex 09103).
• Ultraviolet lamp (for resin polymerization).
• Alcohol for surface cleaning.

Step by step instructions:

1. Clean the chip from dirt and degrease with alcohol.
2. Apply 2-3 drops of the polymer resin from the kit.
3. Install the injector and create a vacuum (follow the instructions for the kit).
4. Irradiate with a UV lamp for 5–7 minutes.
5. Remove excess resin with a blade.

Important: after repair, do not wash the car for 24 hours. The effectiveness of the method is about 80% (the chip will become almost invisible, but the strength of the glass will be restored by only 50%).

Which windshield is best to choose for Nissan Sunny FB15 with the system Around View Monitor?

For cars with all-round cameras (Around View Monitor) It is critical that the glass does not distort light and does not have metallized coatings. Optimal options:

• Original AGC (28510-BM40B) - guaranteed compatibility.
• Saint-Gobain Sekurit (article 765487) - tested for Nissan with cameras.
• NSG/Pilkington (28510-4M000) - requires checking the markings (there must be a mark CV — Camera View).

After replacement, be sure to calibrate the cameras using diagnostic equipment! Without this, the system will show a distorted image.

What to do if after replacing the glass there is a smell of glue in the interior?

It is normal for polyurethane sealant to smell during the first 3-5 days. To speed up weathering:

• Ventilate the interior for 10–15 minutes a day (open all doors).
• Use an ozonizer or carbon filter for the cabin.
• Do not turn on the stove at maximum temperature - this will increase the evaporation of chemical compounds.

If the smell has not disappeared after a week, it means that low-quality glue was used. In this case, contact the service to check the tightness of the seam.
