Thresholds on Nissan Almera N16: everything about selection, replacement and anti-corrosion protection

Nissan Almera N16 is one of the most popular foreign cars on the secondary market, but the weak point of the model is often the thresholds. Owners are faced with corrosion, mechanical damage and the need for replacement. In this article we will look at which thresholds are suitable for Almera N16, how to choose them correctly, replace them and protect them from rust so that the car lasts longer.

Thresholds on Nissan Almera N16 not only perform a decorative function, but also protect the body from dirt, moisture and mechanical influences. However, due to design features (thin metal, weak factory anti-corrosion treatment), they often rust after only 5–7 years of operation. Particularly vulnerable are the attachment points to the door sills and the lower edge. If you do not monitor the condition, corrosion can spread to the side members and load-bearing elements of the body.

Which thresholds are suitable for Nissan Almera N16: original vs analogues

When choosing thresholds for Almera N16 owners are faced with a dilemma: buy original parts from Nissan or analogues from third-party manufacturers. Original thresholds guarantee a perfect fit and durability, but their price can reach 8–12 thousand rubles per pair. Analogues (for example, from Febi, Meyle or SASIC) are 2–3 times cheaper, but do not always match in geometry and metal thickness.

It is important to consider that Nissan Almera N16 was produced in different modifications (sedan and hatchback), and the thresholds for them are not interchangeable. Parts for machines with petrol (1.5/1.8 l) And diesel (2.2 dCi) engines due to different body weights. Before purchasing, check the VIN code or consult the spare parts catalog by body number.

• 🔹 Original thresholds - article number 62600-4M000 (left) and 62601-4M000 (right) for sedan, for hatchback - 62600-4M100 And 62601-4M100. Fits perfectly, but requires painting.
• 🔹 Analogs from Febi - article number 22396 (set of 2 pieces). The quality of the metal is worse, but the geometry is maintained.
• 🔹 Universal thresholds - a cheap solution (from 1.5 thousand rubles), but they require adjustment and welding.
• 🔹 Thresholds with plastic overlays - protect against chipping, but do not protect against corrosion from the inside.

Signs of threshold wear: when replacement is needed

Thresholds on Almera N16 rarely fail suddenly - it is usually a gradual process. The first signs of problems appear after 3–5 years of operation, especially if the car is driven on salty roads in winter. Pay attention to the following symptoms:

• 🔍 Blistering paint - indicates corrosion under the paintwork.
• 🔍 Rusty stains from under the door seals or below the threshold.
• 🔍 Creaks and knocks when moving - may indicate weakening of welds.
• 🔍 Visible holes or rotten areas (usually in the rear of the threshold).

If the corrosion has gone too far, simple stripping and painting will not help - you will need complete threshold replacement or its partial cutting by welding. It is especially dangerous when rust eats through the metal to holes: in this case, moisture gets inside the body, accelerating the destruction of the side members. You can check the condition of the thresholds yourself by jacking up the car or looking under the door seals.

⚠️ Attention! If, when you press the threshold with your finger, the metal bends or crumbles, this is a sign critical wear. In this case, you cannot delay repairs - the body may lose its rigidity, which will affect safety.

Step-by-step instructions for replacing thresholds on Almera N16

Replacing thresholds with Nissan Almera N16 - a labor-intensive process that requires welding and body repair skills. If you are not confident in your abilities, it is better to contact the service. However, if you have the tools (grinder, welding machine, straightening devices), you can do it yourself. Let's consider the process using the example of replacing the right threshold.

Required tools and materials:

• 🔧 Grinder with cutting wheel (125 mm).
• 🔧 Semi-automatic welding (wire 0.8–1.0 mm).
• 🔧 Straightening hammer and anvil.
• 🔧 Anti-corrosion mastic (for example, Dinitrol or Tectyl).
• 🔧 Primer and paint (to match the body color).

Disconnect the negative terminal of the battery

Remove doors or disconnect wiring (if necessary)

Clean the old threshold from paint and rust

Prepare a new threshold (try on, cut to size) -->

Replacement steps:

1. Removing the old threshold. Use a grinder to carefully cut off the old threshold, leaving 1–2 cm of metal for welding. It is important not to damage the side members and struts!
2. Cleaning and straightening. Remove rust and level the surface with a hammer. If necessary, we cut out rotten areas of the body and weld patches.
3. Trying on a new threshold. We attach the part and check the gaps. If necessary, trim with a grinder.
4. Welding. We grab the threshold in several places, then weld it with a continuous seam. We clean the seams and treat them with anticorrosive.
5. Primer and painting. Apply primer, paint in 2-3 layers, and varnish. After drying, install the seals and linings.

What to do if you don’t have a welding machine?

If you do not have the opportunity to weld the threshold, you can use rivets and epoxy glue (For example, 3M 08115). However, this method is less reliable and is only suitable for temporary repairs. For a complete replacement, welding is required!

Anti-corrosion treatment of thresholds: how to protect against rust

Even new thresholds on Almera N16 require additional protection, especially if the machine is operated in aggressive conditions (salt, humidity, temperature changes). Standard factory treatment is often insufficient, so anti-corrosion treatment is recommended every 2–3 years.

There are several protection methods:

• 🛡️ Liquid anticorrosive (For example, Dinitrol 479 or Tectyl Bodysafe) - applied by spraying inside the threshold through technological holes.
• 🛡️ Bitumen mastic (For example, Body 930) - protects from below from mechanical damage.
• 🛡️ Galvanized or electroplated - expensive, but reliable (extends service life by 10+ years).
• 🛡️ Plastic linings - protects against chipping, but does not protect against internal corrosion.

For maximum protection, it is recommended to combine methods. For example, first treat the thresholds from the inside with liquid anticorrosive, then apply mastic on the outside, and after painting, install plastic trims. Don't forget about drainage holes — they need to be cleaned once a year to prevent moisture from accumulating inside.

Comparison of prices for thresholds and replacement work

Threshold and replacement costs vary by region, shop, and parts selected. The table below shows average prices in Russia for 2026.

Threshold type	Cost of parts (for 2 pieces), rub.	Cost of work (for 1 threshold), rub.	Total for replacing a pair, rub.
Original (Nissan)	10 000 – 14 000	4 000 – 6 000	18 000 – 26 000
Analogues (Febi, Meyle)	4 000 – 7 000	3 500 – 5 000	11 000 – 17 000
Universal (no brand)	1 500 – 3 000	4 000 – 6 000	7 000 – 12 000
Repair inserts (partial replacement)	2 000 – 4 000	3 000 – 5 000	8 000 – 14 000

Prices for work may vary depending on complexity. For example, if required cutting and replacing sections of spar, the cost will increase by 30–50%. Also, many services charge an additional fee for painting (from 2,000 rubles per threshold). To save money, you can buy the thresholds yourself and bring them to the workshop - this way you will avoid extra charges.

Common mistakes when replacing thresholds and how to avoid them

Many owners Almera N16 encounter problems after replacing thresholds due to errors in the repair process. Here are the most common of them:

• ❌ Incomplete removal of rust. If even small pockets of corrosion are left, they will quickly spread to the new metal. Solution: use sandblasting or chemical rust converters.
• ❌ Weak welding. Spot welding or a thin seam will cause the threshold to come off. Solution: weld with a continuous seam with a flange.
• ❌ No anti-corrosion treatment. New thresholds without protection will rust in 1–2 years. Solution: process Dinitrolohm or similar compositions.
• ❌ Incorrect painting. Paint without a primer or in one coat peels off quickly. Solution: Apply primer, 2-3 layers of paint and varnish.

Another common mistake is ignoring body geometry after welding. If the thresholds are installed crookedly, this can lead to problems with opening doors or a violation of the interior seal. Before final welding, be sure to check gaps and symmetry using laser level or roulette.

⚠️ Attention! If, after replacing the thresholds, the car becomes worse at holding the road, this may indicate violation of body rigidity. In this case, it is necessary to check the alignment at the stand and, possibly, strengthen the side members.

Alternative ways to protect thresholds without replacement

If the rapids are on your Almera N16 They haven’t rusted through yet, but there are already the first signs of corrosion; you can do without a complete replacement. Here are some effective methods:

• 🔧 Local repairs. Cut out rusty areas, weld in patches and treat with anti-corrosion agent. Suitable for small fires.
• 🔧 Application of zinc coating. Special formulations (for example, Zinc Rich Primer) create a protective layer similar to galvanizing.
• 🔧 Installation of plastic covers. They protect against chips and mechanical damage, but do not protect against internal rust.
• 🔧 Sealing of seams. Tape the joints between the threshold and the body 3M Scotch-Weld or similar sealant.

For temporary protection you can use anti-gravel film (For example, 3M Scotchgard). It is glued to the outside of the threshold and prevents chipping from stones. However, this is not a panacea - if rust has already begun, the film will only mask the problem.

FAQ: Frequently asked questions about thresholds on Nissan Almera N16

Is it possible to drive with rusted sills?

Short term - yes, but it is dangerous. Rusted sills lose their strength, which can lead to body deformation in an accident. In addition, corrosion spreads to the side members, which can lead to loss of body rigidity. If the holes are through, it is recommended to urgently weld them or install new thresholds.

How long does it take to replace thresholds?

In the service, it takes 4–6 hours (with painting - up to 8 hours). If you change both thresholds, the work will take 1–2 days. Replacing it yourself without experience can take up to a week, especially if straightening and adjustment is required.

Is it possible to paint the sills without removing them?

Yes, but the quality will be worse. To complete painting, you need to remove the doors and seals, strip the old paint down to the metal and treat it with anti-corrosive. If you paint “over the top”, after a year or two the paint will begin to peel off.

Which thresholds are better: original or analogues?

Original thresholds Nissan guarantee a perfect fit and durability, but are expensive. Analogs (for example, Febi) are cheaper, but may require modification. If your budget is limited, it is better to take a high-quality analogue and spend money on good anti-corrosion treatment.

How often do thresholds need to be treated with anticorrosive?

Ideally - once every 2–3 years. If the car drives on salty roads in winter, treatment should be done annually. It is also recommended to inspect the thresholds after each winter and repeat the anticorrosive treatment at the first signs of rust.
