A car hood is not just an engine cover, but an important element of aerodynamics and protection of the power unit. For crossover owners Nissan Qashqai second generation (J11 body), the condition of the hood is critical, since it is it that provides access to technical fluids and affects the appearance of the car.
Owners are often faced with the need to replace this element due to accidents, corrosion, or the desire to improve the sound insulation of the engine compartment. We will analyze all the nuances of choosing, installing and operating a hood on a popular model Nissan.
Original hood versus high-quality analogues
When selecting a new part for Nissan Qashqai J11 It’s always worth considering whether to overpay for the original or trust substitute brands. Original hood (OEM) has ideal geometry, which guarantees even gaps around the perimeter and no vibration at high speeds.
However, the price of an original part often scares off car owners. There are quality products on the market analogues from manufacturers from Turkey and China. They can be made of steel or aluminum, which affects the weight of the structure and corrosion resistance.
- 🔧 Punching precision: The original has ideal stiffeners, the analogue may have deviations.
- 💰 Cost: An analogue can cost 2-3 times less than the original spare part.
- ⚖️ Weight: Aluminum analogues are lighter, but steel stamping is more reliable during impacts.
It is important to consider that for the restyled version Nissan Qashqai J11 (after 2017) the hood has a modified shape of the air intakes. An incorrectly selected part may not fit the radiator grilles.
Materials of manufacture and their effect on durability
Most hoods for Nissan Qashqai J11 are made of steel coated with an anti-corrosion compound. However, there are aluminum options that are valued for their lighter weight and lack of rust. Aluminum hood significantly lighter than steel, which reduces the load on the front suspension.
Steel parts, in turn, are more ductile with small impacts, but are susceptible to corrosion if the paint is damaged. Anti-gravel protection becomes mandatory to maintain the appearance of the steel hood in winter.
When choosing a material, you should pay attention to the thickness of the metal. Steel that is too thin can bend under the weight of snow or when pressed inaccurately when washing. Sheet thickness must meet factory specifications to ensure rigidity.
⚠️ Attention! When purchasing a used hood, be sure to check the condition of the inner layer of anti-corrosion coating. Often rust starts from the inside, where it is not immediately visible.
Aluminum does not rust, but it is softer than steel and more difficult to repair. If you plan to do a lot of off-road driving where there is a risk of being struck by branches or rocks, steel may be a more practical choice due to its shape-recovery properties.

The process of replacing the hood: step-by-step instructions
Replacing the hood is a procedure that requires care and the presence of an assistant, since the element has significant weight. Removing the old hood begins with disconnecting the lock cable and dismantling the decorative air intake grille.
It is necessary to unscrew the bolts securing the hinges to the body. It is important to mark with a marker the position of the hinges relative to the hood to simplify subsequent adjustments. Hood hinges often stick, so the use of a penetrating lubricant may be required.
- 🔩 Tools: Set of socket heads, wrenches, screwdrivers, marker for marking.
- 🛡️ Security: Use a support to prevent the hood from falling on you when removing the last bolts.
- 👥 Assistant: A second person is required to hold the part during removal and installation.
Installing a new hood is done in the reverse order. You shouldn’t immediately tighten the bolts all the way—you need to set the geometry first. Hood adjustment carried out by moving the loops in the longitudinal and transverse directions.
☑️ Preparation for replacement
After installation, you need to check the operation of the lock. The cable should move freely, without distortions. If the mechanism jams, the cable needs to be lubricated or replaced. Lock alignment critical to driving safety.
Common mistakes when replacing
Owners often forget to disconnect the battery, which can lead to a short circuit when removing sensors or license plate lights. Also, improper tightening of the hinge bolts can lead to deformation of the metal and the appearance of cracks over time.
Adjusting gaps and lock operation
High-quality installation of the hood is unthinkable without precise adjustment of the gaps. The gaps should be uniform along the entire length of the fender and windshield. Uneven gaps not only spoil the appearance, but can also cause wind whistling at high speed.
Adjustment is carried out through longitudinal slots in the hinges. Loosen the bolts, adjust the hood for level and clearance, then tighten the fasteners. Thrust bolts on hinges help to set the height of the hood relative to the wings.
Pay special attention to the operation of the lock. The lock should work the first time and lock securely. Free play of the cable should be minimal, but sufficient for easy opening from the passenger compartment.
⚠️ Attention! Don't ignore clicks when closing. If the hood does not latch all the way or you hear a vibration noise, the adjustment is not done correctly. This may cause the hood to open while driving.
If the lock is difficult to operate, check the condition of the lubrication in the mechanism. Often the problem lies in contamination or lack of lubricant in the area of the lock and the mate on the body. Lock lubrication must be of high quality, not washed out by water.
Noise insulation and corrosion protection
Many owners Nissan Qashqai J11 are faced with engine noise penetrating into the cabin. Sound insulation of the hood - an effective way to reduce noise levels and slightly improve cabin acoustics.
For these purposes, special materials are used: vibration insulation, noise absorber and heat reflector. It is important not to overload the hood with heavy materials, as this may affect the operation of the gas lifts. Insulation weight must be balanced.
- 🌡️ Thermal insulation: Protects the paintwork from engine overheating.
- 🔊 Sound absorber: Absorbs the sounds of the motor and fans.
- 🛡️ Vibration isolation: Reduces metal surface resonance.
When applying insulation to the inside of the hood, make sure that the material does not touch moving parts or radiators. Clearances to details must be sufficient for air circulation.
Use materials based on bitumen or synthetic resins with reinforcing foil - they retain heat best and do not peel off over time in hot weather.
In addition to sound insulation, the inside of the hood requires anti-corrosion treatment. This is especially true for regions with cold winters and the use of reagents. Anticorrosive applied to internal cavities and joints.
Dent repair and paint restoration
The hood is one of the most vulnerable parts of a car. Hail, rocks from the road or careless parking can leave marks. Restoration of paintwork and dent removal is possible in different ways depending on the degree of damage.
For small dents without damaging the paint, PDR (paintless dent removal) technology is ideal. The craftsman uses special levers and glue pins to straighten the metal from the inside. PDR technology Retains factory finish.
If the varnish or paint is damaged, partial or complete painting will be required. It is important to choose the right shade, since the color Nissan may change over time. Paint selection made according to the color code on the plate in the engine compartment.
| Type of damage | Elimination method | Approximate cost | Complexity of work |
|---|---|---|---|
| Small dent without chips | PDR (pull) | Low | Average |
| Paint chip, scratch | Local painting | Average | High |
| Large dent with paint rupture | Full painting | High | Very high |
| Dent on the stiffener | Partial replacement or straightening | High | Extreme |
In case of serious damage, when the metal is severely deformed, the hood may need to be replaced. Straightening Such an element is often not economically feasible, since the cost of work is close to the price of a new analogue.
Regular washing of the hood from the inside and treatment with anti-gravel film on the outside is the best way to extend the life of the part and maintain the high liquidity of the car for resale.
Frequent malfunctions and their elimination
Over time, the hood mechanisms can wear out. The most common problem is a lock failure or a broken cable. Replacing the hood cable is a relatively simple procedure that you can do yourself.
Hood stops (gas lifts) also often fail. If the hood does not stay open or is too difficult to close, the shock absorbers will need to be replaced. Selection of shock absorbers depends on the weight of the hood and the year of manufacture of the car.
Another problem is corrosion at the hinge attachment points. This can cause the hood to sag. Loop reinforcement or replacing the bolts with new, better ones may solve the problem.
- 🔑 Latch key: If the lock cannot be opened from the interior, use the emergency access key.
- 🔋 battery: Check to see if the battery is dead, as some locking systems rely on electronics.
- 🧴 Lubrication: Regular lubrication of the lock prevents jamming.
⚠️ Attention! If the hood does not open when the handle is pressed, never try to break the glass or force the hood to bend. This will lead to expensive repairs. Use the emergency rope or access key.
Sometimes the problem lies not in the mechanism, but in incorrect adjustment. If you have recently replaced the hood, check the cable tension and the position of the lock. System Calibration may be required after replacing parts.
FAQ: Answers to popular questions
Is it possible to install a hood from a Nissan Qashqai J10 on a J11 model?
No, that's impossible. The J10 and J11 bodies have completely different dimensions and mounting points. The hoods are not interchangeable between these generations.
How often should hood shock absorbers be replaced?
It is recommended to check their condition every 30-40 thousand kilometers. If the hood no longer stays open or closes too quickly, the shock absorbers need to be replaced.
Is it possible to paint the hood a different color from the body?
Yes, this is permitted by law, but requires changes to the PTS. The process includes preparing documents, painting and registering changes with the traffic police.
