The system of fastening of the power unit in the car Skoda Octavia Tour It plays a critical role in driving comfort and transmission durability. Over time, rubber metal elements lose their properties, which leads to the appearance of shocks, vibrations and extraneous noises when the engine is running. Ignoring this problem can cause the destruction of the body of the gearbox or break other components of the suspension of the engine.
Many owners are faced with the need engine-support After a run of 80-100,000 kilometers, especially if the car was operated in bad roads. Unlike the modern models, Octavia Tour Often equipped with time-tested engines of the series 1.6 MPI or turbo versions, where the load on the supports is much higher. Understanding the symptoms of the malfunction and the correct replacement procedure will save you time and money on visits to the service.
Symptoms of wear and fault diagnosis
The first sign that engine mount has become unusable, there is a tangible vibration of the steering wheel and the entire body when the engine is running at idle speeds. This is especially felt when you turn on the transmission or press the gas pedal, stopping at a traffic light. Vibration can be transmitted to the pedals and seats, causing rapid fatigue of the driver.
The second characteristic symptom is loud metal knocks when moving from a place or sharp braking. If you hear a characteristic impact in the engine compartment or under the front bumper, most likely, hydraulic support lost its tightness or the rubber damper completely collapsed. Nana Skoda Octavia Tour With front-wheel drive, the load on the left support (transmission) is especially large.
It is also worth paying attention to the behavior of the car during acceleration. If the car twitches when pressed sharply on the gas, and then a blow to the transmission follows, this is a sure sign that the engine is shifting too much in the under-hood space. Engine pillow no longer performs its damping function, and pulleys as well as pipes may be damaged due to excessive displacement of the unit.
Selection of suitable spare parts for repair
When choosing a replacement for Skoda Octavia Tour It is critical to understand the difference between original parts and analogues. The original backbone of VAG It usually has an article starting with the prefix 1J0 or 1K0 and provides the maximum resource. However, the price of such parts is often overpriced, and many owners are looking for quality alternatives.
Among the verified brands-analogues can be distinguished Lemförder, Febi Bilstein and Sachs. These manufacturers often supply components to the conveyors of automakers, so their quality is closer to the original. Avoid buying the cheapest Chinese parts, as the rubber in them quickly bluffs and cracks, and the hydraulic part can not withstand the loads even after 5 thousand kilometers.
It is important to consider the type of engine of your car. For engines. 1.6 MPI (gasoline) and 1.9 TDI (diesel) supports may differ in stiffness and design of brackets. Before buying, be sure to check the VIN code of the car with the spare parts catalog to make sure compatibility. An error in the selection of the part will lead to the need for rework and additional costs.
- ✅ Lemförder Perfect balance of price and quality, often found in original VAG boxes.
- ✅ Sachs - premium analogue, especially good for hydraulic supports, providing maximum comfort.
- ✅ Febi Bilstein - a reliable German brand, offering a wide range of engine suspension.
Do not forget to check the packaging for the presence of protective holograms and the quality of the print. Fake parts often have blurred barcodes or fuzzy labels on the part itself. If you buy a used support, make sure that it does not have traces of oil, cracks and tears of rubber, as the hydraulic fluid inside could leak.
Preparatory work and necessary tools
Before starting work, you need to prepare the workplace and all the necessary tools. Repair of engine supports Skoda Octavia Tour requires access to the lower part of the engine compartment and often to the wheel arches. You will need a jack, a stable stand (goat) and a set of keys.
To complete the task, you will need the end heads on the 13, 16, 18 and 21 millimeter, and extension and rattle. Be sure to prepare a mount or crowbar to unclog the mounting sites, as bolts are often tightened with great effort and can be sour. Don’t forget WD-40 or a similar thread processing tool.
It is very important to ensure safety. The car should stand on a flat surface, the parking brake is tightened, and recoil stops are placed under the wheels. The engine must be cold to avoid burns when operating in the engine compartment. Disconnect the battery terminal so that you do not accidentally close the wiring during dismantling.
☑️ Preparing to replace the support
If you plan to change the hydraulic mount, make sure you have access to the top and bottom of the mount. Sometimes this requires removing the plastic fender liner or even the engine mudguard. Check the condition of other engine mounting elements, since when one support is removed, the load is redistributed to the others, which can reveal hidden defects.
Step-by-step instructions for replacing the upper support
The process of replacing the upper engine mount with Skoda Octavia Tour It starts with access to the engine compartment. Open the hood and find where the support is attached to the body. There are usually three or four bolts that secure the support to the side member. Inspect the fasteners, clean them of dirt and treat them with penetrating lubricant if the bolts are stuck.
The next stage is to remove the load from the engine. Place a jack under the engine oil pan, using a wooden board to distribute pressure to avoid damaging the aluminum oil pan. Smoothly lift the engine 2-3 centimeters so that the support mounting bolts are no longer loaded. This will allow you to easily unscrew the fasteners.
Unscrew the bolts securing the support to the body and the bolts securing it to the engine bracket. Be prepared for the fact that the support may be pressed with force. Remove the old part and compare it with the new one. Make sure the holes line up and the rubber part is free of defects. Install the new support, but do not tighten the bolts all the way right away.
After installation, lower the engine until it is in its original position, and only then tighten all bolts to the recommended torque. The tightening torque is usually approx. 60-80 Nm for mounting bolts to the body and 40-50 Nm for engine mounting bolts. It is better to check the exact values in the service documentation for your specific engine.
⚠️ Attention! Never lower the engine to the ground without a support in place, as this may cause the cooling system pipes or wiring to break. Always support the engine with a jack until the new fasteners are completely installed.
If you are replacing a hydraulic mount, make sure it is installed in the correct position. Some models are marked "Top" or "Bottom", which should not be confused. Incorrect installation will lead to the fact that the support will not dampen vibrations and will quickly fail. Check that the rubber element is not twisted.
Proper bolt tightening sequence is critical to prevent premature failure of the new mount and body vibration.
Replacing the lower (transmission) support
The lower mount, or transmission mount, is located in the area of the transmission and often experiences heavy loads during acceleration and braking. It is usually accessed through the wheel arch. Remove the front wheel and plastic fender liner to get a clear view of the mounting bolts.
As with the top mount, you will need to support the engine with a jack to take the load off the transmission. Unscrew the bolts securing the support to the body and to the gearbox bracket. Please note that the transmission mounting bolts may be longer and have different threads, so be careful when assembling.
Remove the old support and install the new one. Often the lower support has a rubberized bracket that can be pressed against the body with great force. Use a pry bar to carefully move the mounting points apart and install the bolts. Do not use excessive force to avoid damaging the threads in the body.
Tighten the mounting bolts, making sure the support is level and not twisted. Check the clearances between the support and other suspension or body elements. After installation, lower the engine and check the operation of the transmission by engaging all gears and making sure there is no abnormal noise.
- 🛠 Use an extension to access bolts in hard-to-reach areas of the arch.
- 🛠 Be sure to clean the seats from rust before installing a new part.
- 🛠 Check the condition of the silent blocks of the suspension arms, as they are often replaced along with the supports.
What to do if the bolts are stuck?
If the bolts do not come off, use heat (gas torch) or penetrating oil. As a last resort, you can cut the bolt with a grinder, but this requires caution so as not to damage engine or gearbox parts.
In some cases, replacing the lower support requires removing the subframe, which makes the job much more difficult. If you are not confident in your abilities, it is better to entrust this part of the repair to professionals. Improperly tightening the subframe can cause wheel alignment problems and handling problems.
Torque table and bolt specification
To ensure reliable fixation of the engine mounts, the recommended bolt tightening torques must be observed. Neglecting these values can lead to loosening of the fastener or destruction of the thread. Below is a table with approximate values for most engines Skoda Octavia Tour.
| Mounting type | Bolt diameter | Tightening torque (Nm) | Key Feature |
|---|---|---|---|
| Upper support to body | M10 | 65 ± 5 | High strength |
| Upper mount to engine | M10 | 50 ± 5 | Aluminum housing |
| Lower support for gearbox | M12 | 80 ± 10 | Steel bracket |
| Lower support to the body | M10 | 60 ± 5 | Rubber-metal assembly |
Use a torque wrench for precise tightening. If you don’t have such a tool, tighten the bolts “by hand” until they stop, and then turn them 90-120 degrees, but this is less reliable. Always check the condition of bolt threads before installation. If the threads are stripped or the bolt shows signs of corrosion, it must be replaced.
⚠️ Attention! Do not reuse bolts from old supports if they show signs of deformation or corrosion. Reusing the fastener may lead to its breakage during operation.
Please note that exact torque values may vary depending on the vehicle year and engine type. Always check the official technical documentation or the spare parts manufacturer's catalog. Torque errors can have serious consequences for the chassis.

Features of operation after replacement
After replacing the engine mounts, it is important to let the car “break in” a little. In the first 500 kilometers, avoid sudden starts and braking, as well as driving on rough terrain. The rubber elements of the supports should settle a little and take their working position.
Check engine idle speed one week after replacement. If the vibrations return, there may have been an installation error or a low-quality part was installed. In this case, it is recommended to re-check the tightness of the bolts and the condition of the new supports.
Inspect engine mounts regularly during scheduled maintenance. Pay attention to the presence of cracks in the rubber part, leaks of hydraulic fluid or displacement of the brackets. Timely identification of problems will allow you to avoid costly transmission repairs.
- 🔍 Check the condition of the bearings every time you change the engine oil.
- 🔍 Watch for new vibrations or noises in the cabin.
- 🔍 Avoid overloading the vehicle, as this will accelerate wear on the rubber elements.
Keep receipts for the purchase of spare parts and warranty cards. This will help you, if necessary, make a claim to the manufacturer or seller if a defect is discovered.
High-quality replacement of engine mounts not only eliminates vibrations, but also extends the life of the transmission, preventing destructive impacts and displacement of units.
Frequently asked questions and answers (FAQ)
Is it possible to replace only the rubber part of the support, and not the entire part?
This is technically possible, but not recommended. The rubber part is often welded or pressed, and a quality replacement requires special equipment. In addition, new tires may not provide the required rigidity. It is better to replace the support assembly to guarantee the result.
How long does it take to replace Skoda Octavia Tour engine mounts?
For an experienced craftsman, replacing one support takes from 1 to 2 hours. If you need to change both supports and there are difficulties with access (for example, removing a subframe), the time can increase to 4-5 hours. A beginner should set aside the whole day to work.
Do I need to do a wheel alignment after replacing the bearings?
If you only changed the supports and did not affect the suspension or subframe, a wheel alignment is not required. However, if the subframe had to be removed when replacing the lower support, the suspension geometry may be disrupted and adjustment will become necessary.
Why did the vibration remain after replacing the supports?
The reasons may be different: poor quality part, incorrect installation, wear of other components (for example, pulleys or gearbox mounts), or flywheel imbalance. It is also possible that the engine is misaligned due to problems with other mounts that you did not replace.
Is it possible to drive with one broken support?
Short term - yes, but not recommended. Long-term operation with a damaged support leads to accelerated wear of the transmission, breakage of pipes and even damage to the body. It is better to replace the part as soon as possible.
