Nissan Almera Classic (also known as Samsung SM3 in some countries) is a popular sedan, valued for its reliability and unpretentiousness. However, even this car has a weak spot: rapids, which over time rust, become chipped and lose their presentable appearance. The problem is especially pressing for cars older than 5–7 years or operated in aggressive winter environments.

In this article we will look at which thresholds are suitable for Almera Classic (including restyled versions 2010–2012), how to choose them correctly, install them and protect them from corrosion. We will also consider unique nuances of fastening thresholds on this model, which are often overlooked even by experienced car owners.

Which thresholds are suitable for Nissan Almera Classic: original vs analogues

Before purchasing, it is important to decide on the type of thresholds. They are divided into three categories:

  • 🔹 Original (OEM) - are produced Nissan or official suppliers. They fit perfectly in geometry, but are expensive (from RUB 8,000 per pair). Article number of original thresholds: 62600-4M000 (right) and 62601-4M000 (left).
  • 🔹 Analogs (non-original) - cheaper (from 3,500 ₽), but may differ in the thickness of the metal and the quality of the coating. Popular brands: Febi, Meyle, Hans Pries.
  • 🔹 Universal - suitable for several models (for example, Almera Classic And Renault Logan first generation). They require adjustment, but cost from RUB 2,000.

If your Almera Classic released before 2010, please note threshold size: for pre-restyling models they are 15 mm shorter than for restyling ones (2010–2012). Also check availability holes for attaching plastic covers - some analogues do not have them, and you will have to drill them yourself.

When choosing, pay attention to material:

  • 🛠️ Galvanized steel - the best option for durability, but heavier and more expensive.
  • 🛠️ Aluminum - lightweight and does not rust, but does not withstand impacts (for example, when parking).
  • 🛠️ Plastic with metal frame - cheap, but lasts 2-3 seasons.
💡

Before purchasing thresholds, check their compatibility with your version Almera Classic by VIN code. Some analogues may not be suitable due to differences in attachment to the side members.

Signs of threshold wear: when is it time to change

Thresholds on Almera Classic suffer from three main problems:

  1. Corrosion - starts with small bubbles in the paint, then turns into through holes.
  2. Chips and dents - due to high curbs or gravel.
  3. Peeling of plastic linings — the fastenings become loose and the sills begin to “lobble.”

Particularly vulnerable weld zones (where the sill connects to the spar) and bottom edge, which comes into contact with water and salt. If you notice any of these signs, it's time to act:

  • 🚨 Rust on the inside of the threshold (visible when the door is open).
  • 🚨 Crunch or squeak when you press the threshold with your foot.
  • 🚨 Visible dents or paint peeling.
What happens if you ignore rust on door sills?

If corrosion is not eliminated in time, it will spread to the side members and the underbody. This will lead to loss of body rigidity, which is dangerous in case of an accident. In advanced cases, the car may not pass inspection, and repairs will cost 50,000 rubles or more.

For diagnostics use endoscope (can be bought for 500 ₽ on AliExpress) - it will help you examine the hidden cavities of the thresholds. If there is already rust, but the metal is not completely rotten, you can get by anti-corrosion treatment (For example, Movi or Dinitrol). If there are holes, just replace it.

Step-by-step instructions for replacing thresholds on Almera Classic

You can replace the thresholds yourself if you have welding machine, Bulgarian and experience working with bodywork. Otherwise, it is better to contact a service center - welding errors can weaken the body.

If you decide to do it yourself, follow this algorithm:

Remove the plastic covers (unscrew 4 screws and 2 pistons)

Disconnect the negative terminal of the battery

Wash and degrease thresholds

Protect windows and doors with masking tape

-->

Step 1. Dismantling old thresholds

  1. Cut with a grinder spot welding (usually 8–10 points at each threshold).
  2. Carefully separate the threshold from the side member, being careful not to damage the latter.
  3. Remove any remaining sealant and rust with a metal brush.

Step 2. Preparing new thresholds

  • 🔧 Try on new thresholds, adjust with an angle grinder if necessary.
  • 🔧 Coat the inside anticorrosive (For example, Body 930).
  • 🔧 Drill holes for plastic pads if there are none.

Step 3. Installation and welding

  1. Grab the threshold at 3–4 points semi-automatic welding (wire 0.8 mm).
  2. Check the gaps with the doors (should be the same along the entire length).
  3. Boil the seams completely, then clean them with a sander.
  4. Apply seam sealant (For example, 3M 08593).

Step 4. Painting and anticorrosive

  • 🎨 Primer (for example, Reoflex).
  • 🎨 Painting in body color (paint code for Almera Classic can be found on the plate under the hood).
  • 🎨 Treatment of internal cavities ML oil or Tektile.

Don't skimp on anti-corrosion treatment! Even new thresholds without protection will last no more than 3–4 years in Russian conditions.

Protection of thresholds from corrosion: what actually works

Even new thresholds on Almera Classic require additional protection. Here 5 proven methods extend their life:

Method Protection period Cost (per set) Pros Cons
Anti-gravel film 3–5 years 2 500–4 000 ₽ Invisible, protects against chipping Difficult to glue on your own
Liquid locker (Body 950) 2–3 years 1 500–2 500 ₽ Holds well and is resistant to chemicals Requires surface preparation
Plastic linings 1–2 years 800–1 500 ₽ Cheap, easy to replace Low corrosion protection
Galvanizing (hot method) 10+ years 5 000–8 000 ₽ Maximum protection Expensive, requires removal of thresholds

For Almera Classic most effective combination of methods:

  1. Anti-corrosion treatment of internal cavities (ML oil).
  2. Sticker of anti-gravel film on the outside.
  3. Installation of plastic covers (protect from mechanical damage).
💡

After washing your car in winter, be sure to dry the sills with a hairdryer or compressor. This will remove moisture from the joints and prevent rust.

Top 5 mistakes when replacing thresholds on Almera Classic

Many car owners make critical mistakes that lead to re-corrosion or body deformation. Here are the most common:

⚠️ Attention! If you overheat the spar metal when welding the sills, this can weaken it by 30–40%. In the event of an accident, the body will not withstand the load.
  • ❌ Using "cold welding" instead of normal. Such seams fall apart after a year.
  • ❌ No anti-corrosion treatment after installation. New thresholds will rust in 2-3 winters.
  • ❌ Incorrect fit — if the threshold protrudes or, conversely, is recessed, this leads to the accumulation of moisture.
  • ❌ Ignoring drainage holes. If they are not drilled, water will accumulate inside.
  • ❌ Painting without primer. The paint will quickly fly off, exposing the metal.

Another common mistake is savings on materials. For example, using cheap sealant instead 3M or Teroson leads to the fact that after a year the seams begin to “play” and water gets into them.

How much does it cost to replace thresholds on Almera Classic in 2026

The cost of work depends on the region and level of service. In Moscow and St. Petersburg, prices are 20–30% higher than in the regions. Here are the current prices:

Type of work Cost (₽) Lead time
Replacement of one threshold (with painting) 8 000–12 000 4–6 hours
Replacing a pair of thresholds (with anticorrosive) 15 000–22 000 1–2 days
Local repair (patch) 3 000–6 000 2–3 hours
Anti-corrosion treatment (without replacement) 2 500–4 000 1–2 hours

If you decide to save money and do everything yourself, keep in mind hidden costs:

  • 💰 Rent of a welding machine - 1,500–2,500 ₽/day.
  • 💰 Purchase of consumables (grinder wheels, wire, primer) - 3,000–5,000 ₽.
  • 💰 Painting in a chamber (if there is no garage with an exhaust hood) - 2,000–3,000 ₽.

As a result, independent replacement can cost 12 000–15 000 ₽ (including the purchase of thresholds), which is comparable to the cost of work in the service, but without a guarantee of quality.

Alternative ways to protect thresholds without replacement

If the rapids are on your Almera Classic They haven’t rusted through yet, but there are already the first signs of corrosion; you can do without radical measures. Here 3 working methods:

  • 🔧 Rust converter (For example, Tsinkar). It is applied to cleaned metal, then covered with primer.
  • 🔧 Epoxy resin with fiberglass. Suitable for small holes (up to 2 cm). After hardening, it is sanded and painted.
  • 🔧 Vinyl overlays. Covers chips and protects from new damage. They cost from RUB 1,000 per set.

For temporary protection (for example, before selling a car), you can use liquid rubber (Plasti Dip). It is applied by spraying, lasts 1-2 years and is easily removed. Minus - does not protect against serious corrosion.

If rust has affected more than 30% of the threshold area, no “cosmetic” methods will help. Replacement only!

FAQ: Frequently asked questions about thresholds on Nissan Almera Classic

Is it possible to drive with rusty sills?

It's possible, but dangerous. Rust weakens the body, which increases the risk of deformation in an accident. In addition, Almera Classic with rotten thresholds will not pass inspection.

Which anticorrosive agent is best for thresholds?

For internal cavities - ML oil or Tektil. For external processing - Body 950 or Dinitrol 479. Galvanized thresholds can be additionally coated Tsinkor-Auto.

How long will thresholds last after replacement?

With proper installation and anti-corrosion treatment - 8–10 years. Without protection - 3–4 years (in Russian conditions).

Is it possible to install thresholds from Renault Logan on Almera Classic?

It is possible, but some adjustment will be required: Logan the thresholds are 20 mm narrower. You will also need to drill new holes to attach the pads.

What should I do if, after replacing the thresholds, the doors do not close well?

This means that the thresholds are set skewed. You need to loosen the fasteners, adjust the gaps (should be 3-4 mm) and re-tighten the bolts.
