Replacing the windshield on a Nissan Almera Classic: step-by-step guide and expert advice

Replacing the windshield with Nissan Almera Classic - a task that sooner or later faces every owner of this popular sedan. The reasons can be different: from a banal stone flying out from under the wheels of the car in front, to cracks due to temperature changes or unsuccessful parking under a tree. But regardless of the reason, the procedure requires a careful approach: improper installation can lead to leaks, squeaks, or even the glass peeling off while driving.

In this article we will look at all stages of replacement - from choosing glass and adhesive to final installation and leak testing. We will pay special attention unique nuances Almera Classic (bodies B10 and N16), which are often overlooked even by experienced craftsmen. You will learn how to save on car service services without risking quality, and what mistakes can result in expensive repairs in a year or two.

When replacement is required: cracks, chips and other defects

Not every windshield damage is a reason for a complete replacement. For example, chips up to 2 cm in diameter can be repaired with a polymer compound if they are not located in the driver's line of sight. However, there are cases when replacement is inevitable:

• 🔹 Cracks longer than 10 cm - even if they do not interfere with the view, over time they will diverge due to vibrations and temperature changes.
• 🔹 Damage along the edge of the glass — there is a high probability of leakage, which will lead to corrosion of the body.
• 🔹 Multiple chips (more than 3-4 on an area of 20x20 cm) - repair of such areas is unreliable and spoils the appearance.
• 🔹 Glass deformation after an accident - even if there are no cracks, the geometry may be disrupted, which will affect the view.

On Almera Classic especially vulnerable area under the wiper (due to work load) and top corners (dirt often accumulates here and scratches the glass when washing). If the damage is in heating zone (bottom part of the glass), repair is useless - the threads of the heating elements are damaged, and the glass will have to be replaced.

⚠️ Attention: On models with climate control (optional for N16) a crack in the upper part of the glass can disrupt the operation of the solar sensor, which will lead to incorrect operation of the heating system.

Choice of glass: original vs. analogues, which is better for Almera Classic

There are three types of glass on the market for Nissan Almera Classic:

1. Original (NSG/Pilkington) — manufactured to order from Nissan, have the manufacturer’s logo and a guarantee against optical distortion. Fits perfectly, but the price can reach 15 000–20 000 ₽.
2. Premium analogues (Saint-Gobain, AGC) — high-quality glass from world brands, often used on the assembly line of other brands. They cost 20–30% cheaper than the original.
3. Budget analogues (Chinese, Turkish) — price from 3 000 ₽, but the risk of defects (bubbles, distortions) is up to 15%. On Almera Classic with such glass there are often problems with rain sensor (if installed).

When choosing, pay attention to:

• 🔍 Marking - the original must have a logo Nissan and part code (for example, 28060-BM400 for B10).
• 🔍 Thickness - for Almera Classic standard 4.75 mm (on budget analogues it can be 4.5 mm, which is worse in terms of sound insulation).
• 🔍 Presence of a heating zone — on models with heated glass, the threads must match in location and resistance.

Glass type	Average price (₽)	Pros	Cons
Original (NSG)	15 000–20 000	Perfect fit, no distortion, 2-3 year warranty	High price, long wait (if made to order)
Premium analogue (AGC)	10 000–14 000	Quality close to original, fast delivery	The rain sensor may not fit (check when purchasing)
Budget analogue	3 000–6 000	Low price, quick solution	Risk of defects, worse sound insulation, possible leaks

⚠️ Attention: On Almera Classic N16 with the system ESP non-original glass may cause false sensor alarms due to a different refractive index of light.

Preparing for replacement: tools and conditions

If you decide to change the glass yourself, prepare:

A string or knife for cutting glue (preferably Urethane Cutting Tool)

Suckers for removing glass (minimum 2 pcs.)

Caulking gun (and glue 3M 08609 or SikaTack)

Degreaser (Antisil or isopropyl alcohol)

Primer for glass (3M Glass Primer)

Protective gloves and glasses

Interior protection film (or old sheet)

Construction hair dryer (for heating the glue)

-->

It is important to choose the right time to work:

• 🌡️ Air temperature — from +10°C to +25°C. At low temperatures, the glue does not polymerize well; at high temperatures, it sets too quickly.
• 💧 Humidity - no higher than 70%. In wet weather, the sealant may not provide proper adhesion.
• 🚗 Place - garage or shed. Dust and wind will degrade the installation quality.

Before starting work disconnect the battery (especially if you have a model with airbags in the pillars) and remove the wipers. On Almera Classic Wiper mounts often rust - treat them WD-40 in advance.

What happens if you don't warm up the glue before applying it?

Cold sealant applies unevenly, forming voids. This leads to:

1) Leaks during rain (water will enter the interior through cracks).

2) Creaks when moving (the glass will “play” on uneven surfaces).

3) Detachment of glass in an accident (the glue will not withstand the load).

Step-by-step instructions for replacing a windshield

The replacement process can be divided into 5 stages:

1. Removing old glass

Start by removing the weatherstripping (if present) and moldings. On Almera Classic the moldings are attached with latches - pry them off with a plastic spatula. Then:

1. Mark the glass and body with a marker to ensure proper installation of the new glass.
2. Insert the string into the corner of the glass (between the glue and the body) and start sawing, moving along the perimeter. If there is no string, use knife with rounded blade.
3. When the glue is 80% cut, have a helper support the outside of the glass to prevent it from falling.

2. Surface cleaning

Remove any remaining old glue from the body and glass. On Almera Classic often remains black stripe of old sealant — it needs to be cut off with a knife and then cleaned with sandpaper (P120–P180). Degrease the surface Antisilom and apply a thin layer of primer.

3. Installation of new glass

Before installation, check:

• 🔹 Do they match? holes for sensors (if they exist).
• 🔹 Are there any chips along the edges of the glass (they can become sources of cracks).
• 🔹 Is the seal positioned correctly (on some analogues it needs to be re-glued).

Apply glue to the body solid stripe (no tears!) and carefully install the glass, aligning the marks. Press it evenly around the entire perimeter.

4. Fixation and drying

Secure the glass with tape (crosswise) and leave for 1-2 hours. Then heat the glue with a hairdryer (temperature 40–50°C) to accelerate polymerization. On Almera Classic it is especially important to warm up angles — here the glue sets worse due to the geometry of the body.

5. Leak test

After 6–8 hours (or according to the instructions for the glue), check the joints. To do this:

• 💦 Water the glass with water from a pressure hose.
• 🔦 Shine a flashlight from the interior - if there are cracks, light will leak through.
• 🚗 Drive along an uneven road - squeaks or knocks indicate poor fixation.

Common mistakes and how to avoid them

Even experienced professionals sometimes make mistakes that later turn into problems. Here are the most common ones on Nissan Almera Classic:

• 🚫 Saving on glue - cheap sealants (for example, ABRO) flow when heated and lose elasticity after a year.
• 🚫 Improper cleaning — if there are particles of old glue left on the body, the new glass will lie unevenly.
• 🚫 Ignoring primer — without it, the adhesion of glue to metal is reduced by 40%.
• 🚫 Retightening the wiper bolts - on Almera Classic this leads to cracks in the fastening area.
• 🚫 Installation without an assistant — glass is heavy, and without support it is easy to warp.

Another typical problem is glass shade mismatch. On Almera Classic original glass has a slight greenish tint, while cheap analogues are often transparent. This not only spoils the appearance, but also impairs protection from UV rays (which leads to fading of the dashboard).

⚠️ Attention: If after replacement there is whistling at speeds above 100 km/h, this means that the glass is installed skewed. This can only be fixed by reinstalling it.

Replacement cost: prices in services and self-repair

Windshield replacement cost Nissan Almera Classic depends on the type of glass, region and installation method:

Service/Material	Cost (₽)	Notes
Original glass (NSG)	15 000–20 000	Includes rain sensor (if equipped)
Premium analogue (AGC)	10 000–14 000	Warranty 1–2 years
Budget analogue	3 000–6 000	Risk of defects up to 15%
Work in the service	3 000–7 000	Includes removal/installation, but not always good quality glue
Self-replacement	1 500–3 000	Cost of glue, primer and tools

Car service centers often offer “package” services, for example, glass replacement + tinting with a discount. However, on Almera Classic It is better to do tinting 2-3 days after installing the glass, so as not to disturb the polymerization of the glue.

If you decide to change the glass yourself, please note: hidden costs:

• 🔧 Tool — the string and suction cups will cost 1 000–1 500 ₽ (but they are enough for several replacements).
• 🧴 Consumables - glue 3M 08609 costs about 2 500 ₽, but it is enough for 2-3 installations.
• ⏳ Time — the first time the procedure will take 4–5 hours (in the service — 1.5–2 hours).

What to do after replacement: break-in and maintenance

First 24–48 hours after replacement - critical. During this period:

• 🚗 Do not wash your car under high pressure (only hand washing without a directed jet on the glass is possible).
• 🌧️ Avoid driving in heavy rain - water may seep through the incompletely polymerized glue.
• 🚪 Don't slam doors too hard - vibration can move the glass.
• 🔧 Do not adjust the wipers or turn on the glass heating (if any) for 24 hours.

After 2-3 days, check:

• 🔍 Tightness — after rain, inspect the joints for moisture in the interior.
• 🔊 Noise insulation - if you hear more noise from the road, it means that the glue has not been applied evenly.
• 👁️ Review - Drive on a straight road and check for distortions (especially in the dashboard area).

To extend the life of new glass:

• 🧼 Wash glass without abrasives (sand and hard brushes scratch the surface).
• 🌞 Cover the glass in hot weather light protection screento avoid overheating.
• 🚗 Park with your face away from the road - this will reduce the risk of getting hit by stones.

Frequently asked questions (FAQ)

Is it possible to drive with a crack in the windshield?

If a crack not in the driver's line of sight and its length is less than 10 cm, you can ride, but with caution. However, please note:

• 📜 By Traffic regulations (clause 4.3) a crack in the wiper operating area is a reason for a fine (500 ₽).
• 🚗 At a speed of more than 60 km/h, the crack may begin to “grow” due to vibrations.
• 💧 In the rain, the view through the crack worsens by 2-3 times.

On Almera Classic It is especially dangerous to ignore cracks in top of glass - they often lead to tinting peeling and body corrosion.

What glue is best to use for Almera Classic?

For Nissan Almera Classic recommended:

• 🔹 3M 08609 — universal, polymerization time 1 hour, 10-year warranty.
• 🔹 SikaTack Drive — quick fixation (you can ride in 30 minutes), but expensive.
• 🔹 Dow Automotive Betaseal — optimal for cold climates (does not lose elasticity at -30°C).

Do not use ABRO WS-904 or similar - they are cheaper, but after a year or two they begin to crumble.

Is it possible to replace a windshield in winter?

Technically you can, but with reservations:

• ❄️ You need to work in heated garage (temperature not lower than +10°C).
• ⏳ Glue polymerization time increases by 1.5–2 times.
• 🚗 After replacement, the car cannot be driven out into the cold for 12 hours.

On Almera Classic winter replacement is fraught condensation under glassif the glue does not have time to dry.

What to do if a squeak appears after replacement?

The creaking occurs due to:

• 🔊 Uneven application of glue - The glass needs to be reinstalled.
• 🔊 Dirt getting under the moldings — try cleaning and lubricating with silicone grease.
• 🔊 Glass distortion — check the gaps in the corners (should be the same).

If the creaking appears after 1–2 weeks, the reason is glue shrinkage - this is normal for budget sealants.

How can I check if the glass I received was original?

Signs of original glass on Almera Classic:

• 🔍 Logo Nissan or NSG in the bottom corner.
• 🔍 Marking DOT XXX AS1 (where XXX is the manufacturer code).
• 🔍 Smooth greenish tint (on cheap analogues - transparent or bluish).
• 🔍 Perfectly matching holes for sensors (if any).

Counterfeits often have rough seams along the edges and uneven tinting at the top.
