Removing thresholds on a car Škoda Yeti - a procedure that may be required for a variety of reasons: from replacing plastic linings with higher-quality analogues to completely repainting elements or repairing side members after hidden corrosion. Owners of this model are often faced with the need to access hidden cavities where moisture and road salt accumulate, especially in regions with harsh climates.
The process is not overly complicated, but it requires care and understanding of the body structure. Thresholds on Yeti They are fastened not only with bolts, but also with clips, and also have a specific geometry that can make removal difficult without prior preparation. Failure to do so correctly can result in paint damage or metal deformation, which can lead to serious corrosion in the future.
Preparation of tools and workplace
Before you start work, you need to collect all the necessary equipment. The lack of specialized tools often leads to thread breakage or breakage of plastic fasteners. For bodywork Škoda Yeti you will need a standard set of car keys and specific tools for working with clips.
You will definitely need:
- 🔧 Socket set and ratchet with extensions (sizes 10, 13, 16 mm)
- 🔩 Screwdrivers with flat and Phillips blades (including a wide one for prying plastic)
- 🪜 Jack and safety stands (cats) for safe lifting of the body
- 💨 A can of WD-40 or equivalent for treating rusty bolts
- 🧤 Gloves and safety glasses for hand and eye safety
Preparation of the workplace is no less important than the choice of tools. The car should be parked on a level surface, preferably in a garage or box with good lighting. If you plan to remove the sills on both sides, make sure you have enough room to maneuver. Don't forget to prepare a container to store the loosened bolts and washers so you don't lose them.
⚠️ Attention: Before starting work, be sure to disconnect the negative terminal of the battery. This will eliminate the risk of a short circuit if you accidentally snag the wiring running at the bottom of the doors or threshold.
Pay special attention to cleaning the area around the fasteners. Dirt and sand that get into the threaded connections when unscrewing can cause the bolt to jam. Wipe the fastening areas with a damp cloth and apply penetrating lubricant, giving it time to penetrate into the threads.
Features of the design of thresholds on the Škoda Yeti
Structurally, the thresholds on Škoda Yeti are a complex system consisting of a metal base and plastic linings (for versions with protective moldings). The metal part is the load-bearing element of the body, while the plastic performs aesthetic and protective functions. Understanding this difference is critical to proper disassembly.
Depending on the configuration and year of manufacture, the mounting may vary. On early models, bolted connections hidden under decorative plugs are more common. More recent versions may use a combined system: bolts combined with powerful plastic pistons. It is also worth considering the presence of standard running boards, which are often integrated into the fastening system.
It is important to note that additional fastening points are often hidden under the plastic covers, access to which opens only after removing the decorative part. An attempt to remove the entire assembly without first removing the plastic may result in the latches breaking.
The mounting diagram looks like this:
| Item type | Fastening material | Number of points (approx.) | Difficulty in dismantling |
|---|---|---|---|
| Metal threshold | Bolts M6, M8 | 4-6 pcs. | Average |
| Plastic cover | Clips, screws | 8-12 pcs. | Low |
| Protective molding | Double-sided tape + clips | 3-5 pcs. | High |
| Footrest (optional) | Bolts through the arch | 2-3 pcs. | Difficult |
Before starting disassembly, carefully inspect the side surface of the car. Find all visible plugs and joints. Often the fasteners are hidden in recesses under the door seals, which must be carefully pulled out.
Step-by-step instructions for removing plastic covers
The first stage of dismantling is the removal of plastic elements. This allows you to gain access to the main mounting bolts and avoid damaging them when working with the metal part. You need to act smoothly, without sudden jerks, so as not to break the fragile plastic.
Start by opening the doors and pulling back the rubber seals around the sills. Use a flathead screwdriver wrapped in a soft cloth to avoid scratching the metal or paint. Under the seal you will find the first attachment points, which are often hidden from view.
Next you need to find all visible screws and bolts. They can be located at the ends of the thresholds or in special technological holes. Unscrew them and put them in a safe place. After this you can move on to the clips.
☑️ Preparing to dismantle the plastic
To remove the clips, use a special puller or a wide screwdriver. You need to pry up the plastic in places where there are technological gaps. Pressure should be applied evenly, trying to remove the latch from its seat.
- 🔍 Inspect each fastener before removing
- 🛡️ Use a cloth to protect the paintwork
- 📦 Place removed clips in a separate container.
- 🔄 If the clip is broken, replace it with a new one before reassembling.
After removing all the clips, the plastic should come away from the metal. If the trim does not budge, check to see if there are any hidden screws. Sometimes fastening can be done using self-tapping screws, which are hidden under rubber plugs at the bottom of the threshold.
⚠️ Attention: Do not use metal tools directly on the surface of the plastic or body without a gasket. Chips of paint at fastening points are a direct path to corrosion, especially in winter.
Removing the metal threshold
Once the plastic elements are removed, access to the main bolts holding the metal threshold is available. This is the most critical stage of work, since there is a high risk of damaging the threads or the body itself.
All bolts must be treated with penetrating lubricant and allowed to stand for 10-15 minutes. This is especially true for older vehicles where the fasteners may have been exposed to salt and moisture. Use the correct size socket and ratchet with extension.
Unscrew the bolts sequentially, starting with the outer ones. Do not try to unscrew everything at once, as this may cause the part to become skewed. If the bolt does not budge, do not apply excessive force. Try screwing it back a little to knock off the rust, and then unscrew it again.
After removing all the bolts, the threshold can be held on by sealant or due to friction forces. Carefully pry it up with a pry bar, placing a wooden spacer so as not to damage the metal of the body. Movements must be careful not to deform the spar.
What if the bolt is stuck?
If the bolt does not budge even after applying lubricant, try using heat (hair dryer or torch) to expand the metal. You can also use a special composition for decarbonizing threads. In extreme cases, drilling out a bolt, but this requires high qualifications.
The removed threshold has significant weight and sharp edges. Be extremely careful when carrying it. Place it on a soft surface to avoid scratching the paintwork if you plan to reinstall it.
- Once a year
- Once every 3 years
- Only if necessary
- Never checked
Checking the condition of the body and processing
After dismantling the thresholds, access to the hidden cavities of the body opens. This is the ideal time to check the condition of the metal and carry out anti-corrosion treatment. Often this is where problems begin, which later lead to body rot.
Inspect the spar and internal cavities for rust, chipped paint, or traces of moisture. If you see corrosion, it must be repaired immediately. Sand the damaged areas to bare metal, degrease and apply a rust converter.
To treat hidden cavities, use special anti-corrosion compounds in aerosol cans with a flexible spout. This will allow you to penetrate hard-to-reach places and create a protective layer. The composition should be applied liberally, but without over-wetting.
Be sure to check the condition of the drainage holes at the bottom of the sills. They often become clogged with dirt and leaves, leading to water accumulation and subsequent corrosion. Clean them with wire or compressed air.
- 🧹 Clean cavities from old dirt and bitumen
- 🧴 Apply anti-corrosion compound to metal
- 🔍 Check drain holes for blockages
- 🛡️ Make sure the factory sound insulation is intact
If you plan to paint, after treating the rust and applying primer, allow the surface to dry completely. Only after this can you start painting. Remember that the quality of preparation directly affects the durability of the coating.
⚠️ Attention: Do not ignore the treatment of hidden cavities. Even if the metal looks good on the outside, it may already be damaged by corrosion from the inside.
Installation and reassembly
The process of setting the thresholds back to Škoda Yeti is a mirror image of the dismantling process. However, there are some nuances related to tightness and correct positioning of parts.
Before installing the metal threshold, apply anti-corrosion sealant to the points of contact with the body. This will provide additional protection from moisture and prevent the occurrence of electrochemical corrosion. Place the threshold in place and secure it with bolts.
Tighten the bolts in a crisscross pattern to ensure even fit. Do not overtighten the fasteners to avoid stripping the threads or deforming the metal. Check the tight fit of the threshold to the body along the entire length.
After installing the metal part, proceed to installing the plastic covers. Make sure all clips are intact and ready to go. If the old clips have lost their elasticity or are broken, replace them with new ones. This is critical to prevent moisture from getting underneath the plastic.
Install the plastic covers, carefully inserting the clips into the seats. If necessary, use a rubber mallet to gently seat the part. Make sure that all latches are engaged and the part fits tightly without gaps.
High-quality installation of thresholds requires the use of new clips and the application of sealant to the joints for maximum protection against corrosion.
The final stage is installing decorative plugs and checking the functionality of the doors. Open and close the doors several times to ensure that the thresholds do not interfere with their operation and have no play. Check that the seals fit tightly to the body.
Common mistakes when removing thresholds
Even experienced craftsmen sometimes make mistakes when working with body parts. Knowing these mistakes will help you avoid problems and save time and money. The most common problem is trying to remove a part without prior preparation.
Using the wrong tool may cause the bolt splines to come off or the clips to break. Always use the correct size sockets and quality screwdrivers. Do not attempt to remove rusted bolts without first applying lubricant.
Another common mistake is ignoring the condition of the clips. Many owners try to use old, deformed clips, which leads to gaps and moisture penetration. Always have a supply of new clips for replacement.
Incorrect bolt tightening can also cause problems. A tightening that is too weak will cause vibration and play in the part, while a tightening that is too strong will cause metal deformation or thread breakage. Use a torque wrench to control the force.
- ❌ Don't use the wrong tool
- ❌ Don't ignore the condition of the clips
- ❌ Do not overtighten the bolts
- ❌ Do not skip the anti-corrosion treatment step
You should also avoid working in cold weather. Plastic becomes brittle in the cold and breaks easily. If you must work in cold weather, warm up the room or use a hair dryer to warm up the plastic before removing it.
