Nissan Sunny FB15 is a legendary sedan that is still in demand due to its reliability and simplicity of design. However, even such a time-tested car has vulnerabilities, one of which is protecting the arches and lower part of the body from dirt, sand and chemicals. Mud flaps (or fender liners) solve this problem, but their selection and installation FB15 have nuances that many owners are not aware of.
In this article we will look at everything you need to know about mud flaps for Nissan Sunny FB15: from types of materials and original articles to step-by-step installation instructions and common mistakes that shorten the life of parts. We will pay special attention compatibility with different years of manufacture (1990–1995) and body modifications, and we will also give recommendations on the care of installed elements.
Why are mud flaps needed on the Nissan Sunny FB15?
Many owners Sunny FB15 They underestimate the role of mudguards, considering them only an aesthetic addition. In fact, these parts perform several critical functions:
- 🛡️ Corrosion protection: prevent water, salt and sand from getting on the metal of arches and sills, where rust develops most quickly.
- 🚗 Reduced paintwork wear: Small stones and gravel thrown from under the wheels will eventually wear away the paint on the doors and bumpers.
- 🔧 Simplifying care: dirt and snow do not stick to the inner surfaces of the arches, which makes cleaning easier.
- 💨 Improved aerodynamics: Properly selected mud flaps reduce air turbulence under the wheels, which is especially noticeable at high speeds.
On FB15 the absence of mudguards manifests itself especially quickly: after 2–3 winters, pockets of rust appear on the arches, and the paint on the bottom of the doors becomes dull from constant grains of sand. Research shows that installing high-quality mudguards increases the service life of the body by 30–40% in Russian road conditions.
⚠️ Attention: On models Sunny FB15 with enginesGA14DEAndGA16DEFront mud flaps often come into contact with suspension elements when the vehicle is fully loaded. This leads to friction and premature wear. The solution is to choose flexible polyurethane models or regularly check the fasteners.
Types of mud flaps: what material to choose for FB15?
There are four main types of mud flaps on the market, each with pros and cons for Nissan Sunny FB15:
| Material | Pros | Cons | Service life |
|---|---|---|---|
| Rubber | Flexibility, low temperature resistance, low price | Cracks in the sun, loses elasticity after 3–4 years | 3–5 years |
| Polyurethane | Impact-resistant, does not break in the cold, durable | High price, more difficult to install | 7–10 years |
| Plastic (ABS) | Rigidity, precise fit, average price | Brittle at −20°C, may burst on impact | 4–6 years |
| Composite (rubber + plastic) | Balance of flexibility and strength, UV resistant | More expensive than rubber, limited choice for FB15 | 5–8 years |
For Sunny FB15 the optimal choice would be polyurethane mud flaps — they withstand Russian winters and do not crack upon contact with reagents. However, if your budget is limited, you might consider composite models from trusted brands (for example, Hella or Sidem). Rubber options are suitable only for temporary protection or regions with mild climates.

How to check the compatibility of mudguards?
Compare the shape of the part with the original drawing of the arch (can be found in the repair manual FB15). Pay special attention to:
- the bending radius of the front mudguard (must follow the line of the bumper);
- location of holes for fastening to the side member;
- the length of the rear mudguard (on sedans it is longer than on hatchbacks N14).
Step-by-step instructions for installing mudguards on FB15
Installation of mudguards on Nissan Sunny FB15 does not require special skills, but will require accuracy and a set of tools:
- 🔧 Phillips and flathead screwdrivers
- 🔨 10 mm socket wrench
- 🧲 Magnet for finding fallen fasteners
- 🧴 Silicone grease (for rubber seals)
Sequence of actions:
- Removing wheels: Jack up the car and remove the wheel on the side where you will install the mudguard. For reliability, use stops.
- Removing the old mudguard (if any): Unscrew the screws fastening to the arch (usually 3-4 pieces) and carefully disconnect the clips from the bumper.
- Surface cleaning: Remove dirt and rust from the arch metal, treat with anti-corrosive agent (for example, Molykote or WD-40 Specialist).
- Installing a new mudguard:
- Try on the part without fixing it.
- Fasten the self-tapping screws in the holes of the side member (do not overtighten!).
- Snap the clips onto the bumper (you may need a flathead screwdriver for this).

Mud flaps are installed on the rear axle in a similar way, but there are often no factory holes for fasteners. In this case, you will have to drill them yourself (diameter 6–8 mm) and use bolts and washers.
Before installation, apply a thin layer of silicone grease to the rubber seals of the mudguards - this will prevent them from freezing to the body in winter and extend their service life.
Common installation mistakes and how to avoid them
Even experienced car owners make mistakes when installing mud flaps on FB15, which later lead to problems. Here are the most common:
- 🔩 Pulling screws: This deforms the plastic or rubber, leading to cracks. Solution — tighten the fasteners with a force of no more than 2–3 Nm.
- 🚫 Ignoring anti-corrosion treatment: Without metal protection under the mudguard, rust will corrode the arch in 1–2 years. Solution - use ML-mastic or liquid plastic.
- ❄️ Installation in the cold: Plastic becomes brittle and rubber loses its elasticity. Solution — work at temperatures above +5°C.
- 🔧 Hole misalignment: If the mudguard does not fit on the standard fasteners, you should not drill new holes at random. Solution — use adapter plates or substrates.
Another common problem is friction of the mudguard on the tire when the steering wheel is turned completely. This occurs due to incorrect sizing or deformation of the part. Check the gap (must be at least 10 mm) and, if necessary, bend the edge of the mudguard with a hairdryer.
Before purchasing mudguards, be sure to check their shape with the original drawings FB15. Even a slight misalignment at the edges will result in vibration at speed and premature wear.
Caring for mudguards: how to extend their service life?
Mud flaps on Nissan Sunny FB15 require regular maintenance, especially on Russian roads. Here are the key recommendations:
- 🧼 Washing: Clean mudguards of dirt and salt after every off-road ride. Use a soft brush and car shampoo (eg Karcher RM 539).
- 🛡️ UV protection: Once a season, apply a special conditioner to plastic or rubber parts (for example, Sonax Gummi-Pflege).
- 🔧 Checking fasteners: Every 10 thousand km, check the reliability of the screws and clips. Vibrations on rough roads often weaken them.
- ❄️ Winter preparation: Before cold weather, treat the rubber seals with silicone grease so that they do not freeze to the body.
If cracks appear on the mudguards, do not rush to replace them. Minor damage to rubber or polyurethane can be restored using liquid rubber (For example, Plasti Dip) or epoxy glue. For plastic parts, soldering using a hair dryer is suitable.
⚠️ Attention: Never wash mudguards with high pressure (eg in a self-service car wash). A jet of water can bend the edges of the part, breaking its fit, or tear out the fastening clips.

FAQ: Frequently asked questions about mud flaps on the Nissan Sunny FB15
Can mud flaps from other Nissan models be installed on the FB15?
Theoretically, it is possible to adapt mudguards from Nissan Pulsar N14 or Primera P10, but some adjustment will be required: trimming the edges and drilling new holes. However, this violates the integrity of the protection, so it is better to look for original parts or high-quality analogues specifically for FB15.
How often do you need to change the mudguards on the Sunny FB15?
Service life depends on the material:
- Rubber: 3–4 years (cracks from UV and cold).
- Plastic: 5–6 years (become fragile).
- Polyurethane: 8–10 years (longest lasting option).
It is recommended to inspect parts every 2 years and replace them at the first sign of wear.
Is it possible to drive without mudguards if the arches are treated with anticorrosive?
Anti-corrosion treatment protects the metal from rust, but does not protect against mechanical damage (stones, sand) and does not prevent the adhesion of dirt. Mud flaps perform an additional protective function, so their absence reduces the service life of the body even if anticorrosive is present.
What to do if the mudguard rubs against the tire?
Causes and solutions:
- Incorrect installation → Reinstall the part, check the gaps.
- Mudguard deformation → Heat with a hairdryer and straighten or replace.
- Suspension wear (sagging springs) → Check shock absorbers and springs.
A temporary solution is to place a rubber spacer under the mount to increase the clearance.
Which mudguards are better: universal or original?
Original (or their high-quality analogues) are always preferable, since they:
- Exactly repeat the shape of the arches FB15.
- They have standard fastenings without modifications.
- They do not create additional noise at speed.
Universal mud flaps are cheaper, but often require adjustment and provide poorer protection against splashes.
