Owners of a popular hatchback Nissan Note the first generation with the E11 body index often encounter the problem of vibrations that occur even when the engine is running at idle speed. Often the culprit of this unpleasant phenomenon is the suspension element of the power unit, namely engine mount. This part takes on enormous loads, dampening vibrations and preventing their transfer to the car body.
Many car owners mistakenly believe that if the car drives, then the part is in good working order, but in reality rubber-metal hinge can be destroyed from the inside, causing discomfort and accelerating wear of other components. Understanding of design and operating principles engine mounts on the model Nissan Note E11 will allow you to diagnose the problem in time and avoid costly transmission repairs.
Design features of engine mounts on Nissan Note E11
Power unit mounting system Nissan Note The E11 is designed taking into account the compactness of the body and the specific installation of the engine. Typically, a car is equipped with three main mounting points: top support, bottom support and side (or rear). Each of them has its own design features and material, which directly affects the service life and behavior of the car.
The top mount, often called the “cup,” is responsible for holding the engine upright and dampening vertical vibrations. The bottom is used hydraulic support or reinforced rubber, which absorbs torque during acceleration and braking. The side support secures the unit from displacement in the transverse plane when cornering.
Particular attention should be paid to the material. Factory parts use high-quality rubber, but over time it becomes tanned due to temperature changes and oil. Hydraulic support membrane may burst, which will lead to loss of damping properties and the appearance of a dull knock when driving over uneven surfaces.
Main symptoms of malfunction and diagnostic methods
Engine mount wear can be determined by a number of characteristic symptoms that become noticeable to the naked eye or by ear. The very first signal is the appearance of strong vibration on the steering wheel and pedals when the engine is running, especially in neutral gear with the air conditioner on. If the vibration disappears when you shift to neutral or turn off the engine, the problem is almost certainly in the mountings.
The second obvious sign is a knocking or metallic grinding sound when starting from a stop or sharp braking. This indicates that the engine has sagged or shifted, and the metal is hitting the body. It is also worth paying attention to oil leaks on the support body if it is a hydraulic part. The presence of liquid on the rubber indicates depressurization of the membrane.
For an accurate diagnosis, it is necessary to visually inspect the elements. Rubber breaks, cracks in the cushions, or a complete lack of clearance between metal parts indicate that the part requires immediate replacement. Motor offset relative to its regular place is also easily determined by inspecting the gaps in the engine compartment.
⚠️ Caution: Ignoring signs of engine mount wear can result in damage to exhaust system components, rupture of coolant hoses, or even destruction of the transmission due to constant shock loads.
⚠️ Attention: Do not try to diagnose a malfunction only by appearance without checking the rigidity of the fastening. Sometimes seemingly intact rubber has already lost its elastic properties and works like stone.

Choosing a spare part: original or high-quality analogue?
When selecting a new engine mount for Nissan Note E11 car owners often face a dilemma: buy an expensive original or save on analogues. Genuine Nissan parts (catalog number usually begins with the prefix 11210) guarantee an exact match to the geometry and quality of materials, but their cost can be high. In addition, the original is often sold complete with fasteners, which simplifies installation.
There are proven analogue manufacturers on the market, such as Lemforder, Febi Bilstein or Sasic. These companies produce parts that are often installed on an assembly line, but are sold under their own brand. They offer good value for money, but when purchasing, you need to carefully check the labeling and the integrity of the packaging. Some cheap analogues use less resistant rubber, which is quickly destroyed by reagents and oils.
- 🔍 Always check the part number with the number in your VIN code, as the mounts may differ depending on the engine type (1.4, 1.5 or 1.6 l).
- 🔍 Avoid buying used supports, as the rubber resource is calculated in years and mileage, and it is impossible to visually determine the remaining resource.
- 🔍 When buying an analogue, give preference to brands specializing in suspension and rubber-metal products rather than universal “Chinese” brands.
Before purchasing, be sure to check the condition of the mounting bolts. If the threads are torn or the bolts are stuck, it is better to immediately purchase a set of new fasteners so as not to waste time restoring them when installing a new part.
Step-by-step instructions for replacing the engine mount
Replacing the engine mount with Nissan Note E11 is a task of medium complexity, requiring a lift or inspection pit, as well as a set of tools. The process begins by de-energizing the battery and removing the air filter to gain access to the top mount. For work you will need socket wrenches, a jack and reliable stands.
First you need to secure the engine so that it does not fall when unscrewing the fasteners. Place a jack under the oil pan (over a wooden block for protection) and lift the engine slightly. Then unscrew the bolts securing the old support. Be prepared for the fact that the bolts may become stuck, so treat them with penetrating lubricant in advance. After removing the old part, install the new one, observing the bolt tightening order.
- 🛠️ Use a torque wrench to tighten the bolts to the torque specified in the technical documentation to avoid overtightening or undertightening.
- 🛠️ Be sure to clean the seats of dirt and rust before installing the new support to ensure a tight fit.
- 🛠️ After installation, lower the engine from the jack smoothly, making sure that the mounting holes line up without distortion.
☑️ Tools for replacing engine mount
What to do if the bolt does not come off?
If a bolt is stuck, do not try to break it. Use heat (blowtorch or hair dryer) to expand the metal, apply a generous amount of penetrating lubricant and allow time to work. As a last resort, you can use a bolt cutter or drilling, but this requires high skill.
The nuances of replacing the support for different engine modifications
Model range Nissan Note The E11 offers a variety of powertrain options, and their mount designs may vary significantly. For series engines HR14DE (1.4 l) and HR16DE (1.6 L) top mounts often have a similar design, but may differ in how they are mounted to the body. Turbocharged engines, if found in specific versions, require more massive and durable supports due to increased loads.
Particular attention should be paid to diesel versions with an engine K9K (1.5 l). A diesel engine operates with high vibrations and has a different center of gravity, so the supports for it are often equipped with reinforced hydraulics. Installing a gasoline mount on a diesel engine is unacceptable, as it will quickly collapse and will not be able to dampen the low-frequency vibrations characteristic of a diesel engine.
When replacing the support on front-wheel drive versions, it is also important to consider the condition of the drives. If, when dismantling the support, you notice play in the CV joints, this is a reason to replace them, since the engine displacement could be caused by broken drives. Due diligence suspension of the power unit will guarantee the absence of vibrations after repair.
⚠️ Attention: When working with diesel engines Nissan Note E11, use only specialized supports designed for high vibration loads, otherwise replacement will be required within a couple of months.
The differences in the design of the mounts for gasoline and diesel engines are critical: using the wrong part will lead to rapid destruction of the unit and new vibration problems.

Diagnostics after repair and prevention
After installing the new supports, a test drive and careful inspection should be carried out. Start the engine and have a helper press the gas and brake firmly while you are near the car. You should not see significant engine movement or hear any knocking. There should be no vibration in the steering wheel even with the air conditioning on.
To prevent premature wear of the supports, try to avoid sudden starts and emergency braking, especially on uneven roads. Regularly check the condition of the rubber elements for cracks and leaks. Timely lubrication bolted connections helps to avoid their souring, which will simplify future replacement.
If you notice that the vibration has returned a short time after replacement, it is possible that a defective part was installed or a related defect, for example, wear of the gearbox mounts, was not corrected. In this case, repeated diagnostics by a qualified specialist is necessary. Sometimes the vibration problem lies not in the supports, but in crankshaft imbalance or problems with the ignition system, which must be ruled out first.
High-quality installation and the correct choice of parts are the key to the fact that new supports will serve their entire intended life without the need for repeated repairs.
