Nissan Teana J32 is a popular business sedan, but even it has weaknesses. One of them is thresholds, which often suffer from corrosion, mechanical damage or wear. In this article we will look at everything you need to know about thresholds for Teana J32: from the selection of original and non-original parts to step-by-step replacement and rust protection.
Thresholds are not just a body element, but an important part of the safety and aesthetics of the car. They protect the bottom from dirt, moisture and impacts, and also affect the rigidity of the body. If you notice rust, dents or cracks on the door sills of your Teana J32, the problem cannot be ignored: this can lead to serious consequences, including rotting of the load-bearing elements.
We have collected all the necessary information: article numbers of original thresholds, the best analogues, step-by-step replacement instructions, tips on anti-corrosion treatment and answers to frequently asked questions. The article will be useful for both beginners and experienced car owners.
Original thresholds for Nissan Teana J32: articles and features
If you decide to install original thresholds, it is important to know their part numbers. For Nissan Teana J32 (2008–2013) the manufacturer offers left and right parts separately. Here are the main items:
- 🔧 Left threshold (front):
62601-JM00A(for models with gasoline engines) - 🔧 Right threshold (front):
62600-JM00A - 🔧 Left threshold (rear):
62611-JM00A - 🔧 Right threshold (rear):
62610-JM00A
The original thresholds are made of galvanized steel, which provides good protection against corrosion. However, their price can reach 15–20 thousand rubles per set, so many owners choose analogues.
When purchasing original parts, pay attention to marking: there should be a logo on the door sills Nissan and batch number. Also check the package contents - sometimes the kit comes with additional fasteners.
⚠️ Attention! There are often counterfeits of original thresholds on the market. You can distinguish them by the quality of the welds and weight - the original parts are heavier.
- Original (Nissan)
- Analogues (Dorman, Febi, etc.)
- Used from disassembly

Analogs of original thresholds: what to choose?
If the original thresholds are too expensive, you can consider analogues from trusted manufacturers. They are cheaper, but not always inferior in quality. Here are the best brands:
| Brand | Article (example) | Price (per set) | Features |
|---|---|---|---|
| Dorman | 926-100 / 926-101 |
8 000 – 12 000 ₽ | Good metal quality, but requires adjustment |
| Febi | 26130 / 26131 |
9 000 – 13 000 ₽ | Medium quality galvanization, suitable for budget repairs |
| AMC | NIS62600 / NIS62601 |
7 000 – 10 000 ₽ | Budget option, may require additional processing |
| Hans Pries | 62600-4W000 |
10 000 – 14 000 ₽ | High quality, close to the original |
When choosing analogues, pay attention to metal thickness (optimally - 0.8–1 mm) and the presence of galvanization. Cheap thresholds without protection will quickly rust.
Also check compatibility with your modification Teana J32. For example, thresholds for versions with 2.5 V6 may differ from parts for 3.5 V6.
Before purchasing analogues, check the manufacturer's catalog - some brands indicate compatibility only with certain years of manufacture.
When do you need to change the thresholds to Nissan Teana J32?
Replacement of thresholds is required not only for visible rust. Here are the main signs that it's time to act:
- 🔍 Through corrosion - holes or severe thinning of the metal.
- 🚗 Deformation after an accident - even small dents can disrupt the geometry of the body.
- 💧 Blistering paint - a sign of rust under the paintwork.
- 🔧 Detachment of seals — moisture gets inside the threshold.
If these problems are ignored, corrosion will spread to spars and bottom, and repairs will cost many times more. For example, replacing a rotten spar with Teana J32 may cost from 50,000 rubles.
To check the condition of the thresholds, inspect them from below (preferably on a lift) and tap them with a hammer. A dull sound indicates rust inside.
⚠️ Attention! If the sills are rusted through, it is dangerous to drive such a car - the body loses rigidity, which threatens safety in an accident.
Step-by-step instructions for replacing thresholds with Nissan Teana J32
Replacing thresholds is a complex procedure that requires welding. If you do not have experience, it is better to contact a body shop. But if you decide to do everything yourself, follow these instructions:
Place the car on a lift or overpass|
Disconnect the negative terminal of the battery|
Remove doors (if necessary)|
Protect your windows and interior from sparks |
Prepare your welding machine and grinder -->
Step 1. Dismantling the old threshold
Using a grinder, carefully cut off the welds securing the threshold to the body. Be careful not to damage adjacent panels. Then remove any remaining sealant and rust.
Step 2: Adjusting the new threshold
Try on the new part and adjust it to size if necessary. Please note holes for mounting footrests and seals.
Step 3. Welding
Tack the threshold in several places, then weld the seams with a continuous seam. Use semi-automatic welding in CO₂ environment for better quality.
Step 4. Processing the seams
Clean the seams with a grinder, apply primer and sealant. After drying, paint the threshold in the color of the body.
If you are not confident in your welding skills, leave this job to professionals. Poor quality seams can lead to corrosion and weakening of the body.
What to do if the threshold is welded crookedly?
If after welding the threshold is displaced, it can be leveled using a jack and wooden blocks. The main thing is not to overdo it, so as not to deform the body. In extreme cases, you will have to cut off the part and redo the work.
Anti-corrosion treatment of thresholds: how to protect against rust?
Even new rapids need protection. Here are effective anti-corrosion treatment methods for Nissan Teana J32:
- 🛡️ Movil and analogues — liquid compositions for internal processing. Apply through technological holes.
- 🔥 Hot wax — reliable protection for 2–3 years. Requires professional equipment.
- 🧴 Anti-gravel coating — protects against chips and mechanical damage.
- 🔧 Galvanizing - the most durable method, but expensive and time-consuming.
For self-processing, we recommend using Movil with rust converter. Algorithm of actions:
- Wash and dry the thresholds thoroughly.
- Remove rust with a brush or sandpaper.
- Apply a rust converter (eg Tsinkar).
- After drying, treat the thresholds with Movil inside and out.
Repeat processing every 1–2 years, especially before winter. This will significantly extend the life of the thresholds.
Regular anti-corrosion treatment of thresholds saves up to 30-40% on body repairs in the long term.
Frequent mistakes when replacing and protecting thresholds
Many car owners make mistakes that lead to the rapid return of corrosion. That's what can't do:
- 🚫 Ignore internal processing — Rust often starts from the inside.
- 🚫 Use cheap paint - it quickly cracks and peels off.
- 🚫 Weld thresholds without protecting adjacent panels - the paintwork can be damaged.
- 🚫 Save on sealant - moisture will penetrate the seams and start corrosion.
Another common mistake is wrong choice of thresholds. For example, installing parts from Nissan Teana J31 (previous generation) will lead to problems with fastening.
If you doubt your abilities, it is better to turn to specialists. A high-quality replacement of thresholds with a guarantee will cost 20–30 thousand rubles, but will save time and nerves.
FAQ: Frequently asked questions about thresholds Nissan Teana J32
Is it possible to restore thresholds without replacement?
Yes, if the corrosion is superficial. To do this, patch welding, putty and anti-corrosion treatment are used. However, if there is rust through or deformation, a complete replacement is more reliable.
How long does it take to replace thresholds?
In the service, work takes 1–2 days (depending on complexity). Do-it-yourself replacement can take up to a week, especially if fitting and painting are required.
Which thresholds are better: original or analogues?
The original ones are more reliable, but more expensive. Analogs (for example, Dorman or Hans Pries) are suitable for budget repairs if handled correctly.
How often do thresholds need to be treated with anticorrosive?
Optimally - once every 1–2 years. If the car is operated in aggressive conditions (salt, humidity), treatment should be done more often.
Is it possible to drive with rusty sills?
Short term - yes, but it is dangerous. Corrosion weakens the body, which can lead to accident deformation or tearing off the threshold while driving.
