<em>Nissan Almera Classic</em> windshield: how to choose, replace and save

Nissan Almera Classic (also known as Nissan Sunny B15 in some markets) is one of the most popular sedans in Russia due to its reliability and affordability. However, even this “indestructible” car has a weak spot: windshield. Stones from under the wheels, temperature changes and time take their toll, and sooner or later the owner faces the question of replacement.

In this article we will look at all the nuances - from choosing between the original and analogues to step-by-step instructions for replacement. You will find out what glass suitable for restyled and pre-restyled versions Almera Classic (2006–2018), how to avoid mistakes during installation and why a cheap replacement can result in expensive body repairs. We’ll also reveal secrets on how to extend the life of new glass and save on car service costs.

1. Which windshield is on Nissan Almera Classic from the factory?

From factory to Almera Classic (including restyled versions 2013–2018) a windshield from a Japanese manufacturer was installed Asahi Glass Co. (AGC) or Nippon Sheet Glass (NSG). The original glass has the following characteristics:

• 🔹 Article: 28510-BM400 (for models up to 2013) or 28510-BM401 (restyling)
• 🔹 Thickness: 4.76 mm (laminated, triplex)
• 🔹 Stripe Color: greenish tint for protection against UV rays
• 🔹 Sensors: area for mounting a rain/light sensor (if installed)

Important: on vehicles with climate control or automatic lighting The glass has a special coating for sensors. If you buy regular glass, the system may not work correctly! Check your equipment Almera Classic before purchasing.

How to distinguish an original from a fake? Factory glass must contain:

• 🏷️ Logo Nissan or AGC in the corner (usually bottom right)
• 📜 Marking with code DOT And E (European certificate)
• 🔍 Smooth edges without chips or bubbles in laminate

2. Original vs analogues: what to choose for replacement?

Price of original glass from Nissan (article 28510-BM401) starts from 18,000–22,000 rubles (for 2026). But there are worthy analogues on the market that will cost less, but will not be inferior in quality.

Manufacturer	Article	Price, ₽	Features
AGC (original)	28510-BM401	18 000–22 000	Perfect fit, UV protection, durability
Pilkington (UK)	N1345012	12 000–15 000	High quality, suitable for sensors
Saint-Gobain Sekurit (France)	555 100 088	13 000–16 000	Good sound insulation, chip resistant
XYG (China)	WN-0157	5 000–8 000	Budget option, but frequent complaints about optical distortion
BOS (Russia)	LS-1015	9 000–11 000	Good price/quality ratio, but shorter service life

⚠️ Attention: Cheap Chinese glass (for example, FYG or Linglong) often have distorted optics within the driver's viewing area. This leads to rapid eye fatigue and can be dangerous when driving at night. If your budget allows, choose Pilkington or Saint-Gobain — they are as close as possible to the original.

Tip: Before purchasing, check whether there is any on the glass hole for rain sensor (if it is installed in your machine). Some analogues do not have this hole, and you will have to drill it yourself - and this risks cracking!

3. When to replace your windshield: 5 obvious and 2 hidden signs

Many owners Almera Classic They put off replacing glass until the last minute, not realizing that even minor damage can lead to serious problems. Here's when replacement is necessary:

• 💥 Crack longer than 10 cm - even if it does not interfere with the view, over time it will move further due to vibrations.
• 🕳️ Chips in the driver's viewing area (according to GOST - no closer than 30 cm from the steering wheel). They scatter the headlights of oncoming cars.
• 🌧️ Depressurization — if the glass “sweats” from the inside or condensation appears on it between the layers.
• 🚨 Damage to the mirror mounting area - this weakens the structure and can lead to glass flying out in an accident.
• 🔍 Optics distortion — if objects appear “wavy” through glass, this is a sign of deformation.

And now about hidden signsthat many people miss:

1. Noise in the cabin at speeds above 90 km/h. If the glass does not fit tightly to the body, a whistle appears. This is a sign that the sealant is worn out and the sun glass may fly out.
2. Corrosion under the seal. On Almera Classic The metal under the windshield often rusts. If you don't replace the glass on time, the rust will "eat" the body and you'll have to cook!

What happens if you drive with a cracked glass?

The crack not only impairs visibility, but also weakens the rigidity of the body by 30–40%. In the event of a frontal impact, the glass may not withstand the load and fly out, resulting in injury to the driver and passengers. In addition, when it rains, water penetrates under the seal, causing corrosion and short circuits in the wiring.

4. Step-by-step instructions: how to replace a windshield with Almera Classic with your own hands

Replacing glass at a car service center will cost 5,000–8,000 rubles (excluding the cost of the glass itself). If you have time and a desire to save money, you can do it yourself. The main thing is to take your time and follow the instructions.

Glass (new, with suitable article number)

Sealant cutting knife (or string)

Glass suction cups (2 pcs.)

Sealant for auto glass (for example, 3M Windshield Urethane>)

Primer (primer for glass)

Construction hair dryer (for heating sealant)

Screwdriver and wrenches for removing wipers and plastic covers

Gloves and masking tape -->

Step 1. Preparing the car

Park the car in a warm, dry place (garage or box). Remove the windshield wipers, plastic covers under the windshield, and rearview mirror. Disconnect the negative terminal of the battery to avoid short circuit when working on the sensor wiring.

Step 2: Removing old glass

Using a knife or string, carefully cut off the old sealant around the perimeter of the glass. Start at the top corner and work your way down. If the glass is cracked, cover it with tape to prevent glass shards from flying around. Use suction cups to remove the glass - do not pull it towards you, but swing it back and forth.

Step 3. Cleaning the body

Remove any remaining sealant from the body and glass frame. Process metal anti-corrosion compound (on Almera Classic The area under the glass often rusts). Apply primer to the installation site - this will improve the adhesion of the new sealant.

Step 4. Installing new glass

Apply sealant to the body frame solid line (no breaks!). Install the glass starting from the bottom and press it evenly. Use suction cups to avoid distortions. After installation, cover the glass with tape and do not touch the car. minimum 6 hours (the sealant must polymerize).

Step 5. Check and assemble

After 6-12 hours, check the tightness: pour water on the outside of the glass - there should be no leaks inside. Reinstall the wipers, trims and mirror. Connect the battery and check the operation of the sensors (if any).

💡

If you are inexperienced, practice on old glass before installing new glass. For example, try applying sealant to an unwanted surface to feel the consistency and pressure.

⚠️ Attention: If on your Almera Classic system installed ESP or airbags, before replacing glass necessarily reset errors via diagnostic scanner (for example, ELM327). Otherwise it may catch fire Check Engine or the airbag fails in an accident!

6. How to extend the life of your windshield: 7 practical tips

Even the highest quality glass will not last long if you do not follow simple rules. Here's what will help you avoid cracks and chips on your Almera Classic:

• 🚗 Keep your distance on the highway - most chips appear from stones flying out from under the wheels of trucks in front. The optimal distance is 50–70 meters.
• 💧 Do not wash glass with cold water in cold weather — a sharp temperature change leads to microcracks. Use a special glass deicer.
• 🔧 Check your tire pressure — if the tires are flat, the risk of “throwing” stones increases 3 times.
• 🧴 Apply a protective coating - for example, "Liquid glass" or Ceramic Pro. It reduces the adhesion of dirt and stones to glass.
• 🚘 Park in the shade - Direct sunlight makes glass brittle over time.
• 🔩 Tighten the wiper bolts - if they dangle, vibration is transmitted to the glass, which leads to cracks.
• 🛠️ Treat the seal regularly silicone grease - this will prevent it from cracking and leaking.

If it has already appeared on the glass small chip (up to 2 cm), it can be repaired using a polymer composition (for example, Permatex Windshield Repair Kit). But remember: repairs are only possible if:

• The chip is not in the driver's field of vision;
• There are no cracks extending from the chip;
• The damage does not affect the inner layer of glass.

💡

If the crack starts from the edge of the glass, repair is useless! In 90% of cases it will go further due to body vibrations. It is better to replace the glass immediately.

7. Common mistakes when replacing glass and how to avoid them

Even experienced craftsmen sometimes make mistakes, which then cost the owners Almera Classic in a round sum. Here are the most common mistakes:

1. Using the wrong sealant. Cheap formulations (for example, "Moment" for glass) do not withstand vibrations and temperature changes. After a year, the glass will begin to “walk”, whistling and leaks will appear.
2. Failure to comply with the polymerization time. If you drive less than 6 hours after replacement, the sealant will not have time to set and the glass may move.
3. Ignoring corrosion under the seal. On Almera Classic Metal under glass often rusts. If it is not treated before installing new glass, corrosion will continue to spread.
4. Incorrect installation of the rain sensor. If the sensor is displaced or there is sealant left under it, it will operate falsely (for example, turning on the wipers without rain).
5. Saving on primer. Without a primer, the sealant does not adhere well to the metal, and the glass may fly out in an accident.

How to avoid these mistakes?

• 📋 Use only certified sealant (For example, 3M 08609 or Dow Automotive Betaseal).
• ⏳ Hold on minimum 6 hours before the trip (ideally 12 hours).
• 🔍 Before installation, clean the metal under the glass and treat it anticorrosive (For example, Dinitrol 4010).
• 📐 Check the position of the rain sensor using the marks - it should be strictly in the center of the viewing area.

What to do if a whistle appears after replacement?

A whistle at speeds above 90 km/h indicates that the glass does not fit tightly to the body. Reasons:

1) There is not enough sealant in some places.

2) The glass is installed skewed.

3) The seal is not glued or damaged.

Solution: return to the service center and reinstall the glass. If the whistle remains, require replacement of the seal.

FAQ: Frequently asked questions about windshields Nissan Almera Classic

Is it possible to drive with a cracked glass if the crack does not interfere with your view?

Technically it is possible, but undesirable. A crack weakens the rigidity of the body by 30–40%, which is dangerous in the event of an accident. In addition, when it rains, water penetrates under the seal, causing corrosion. If the crack is longer than 10 cm or comes from the edge, glass is needed urgently replace.

Is glass suitable from Nissan Sunny B15 on Almera Classic?

Can I repair a chip in the glass myself?

Yes, if the chip is no more than 2 cm and is not in the driver’s field of vision. To do this you will need a glass repair kit (for example, Permatex or Rain-X). Instructions:

1. Clean the chip from dirt.
2. Stick on the applicator from the kit.
3. Fill the chip with polymer.
4. Remove excess and let dry for 30 minutes.

If the crack is caused by a chip, repair is useless, only replacement.

What to do if condensation appears inside after replacing the glass?

This is a sign depressurization. Reasons:

• The frame was poorly cleaned before installation;
• Poor quality sealant was used;
• The glass is installed skewed.

Solution: return to the service and request reinstallation. If you don't help, the glass will have to be replaced again.
