The Cost Of Replacing Your Car's Plastic Undercover

The plastic cover under your car, also known as an engine splash shield, skid plate, or lower engine cover, is an important component that protects your vehicle's engine from damage. Over time, this plastic panel can become loose, cracked, or damaged and may need to be replaced. The cost of replacing the plastic cover under your car can vary depending on several factors, including the make and model of your vehicle, the extent of the damage, and the type of material used for the replacement. On average, a new engine splash shield can range from $10 to $150, but prices can go higher depending on the brand and material. For example, metal splash guards are typically more expensive than plastic ones. In some cases, you may be able to find cheaper aftermarket parts that fit your vehicle, but it's important to ensure they meet the original equipment quality standards.

Cost of replacement

The cost of replacing a plastic cover under a car, also known as an engine splash shield, skid plate, or lower engine cover, can vary depending on several factors. Firstly, the cost depends on the extent of the damage. If the damage is minimal, you may be able to fix it with simple tools and avoid the cost of replacement. However, if the panel is severely damaged or missing, a replacement will be necessary.

The material of the plastic cover is another factor influencing the cost. On average, an engine splash shield can cost anywhere from $10 to $150, but some skid plates can exceed $150 depending on the brand and material. Metal splash guards tend to be more expensive than plastic ones. For example, a plastic engine splash shield for a 2014-2019 Highlander/Hybrid costs around $67.95, while a similar product for a 2016-2021 Tucson costs $193.95.

Additionally, the size and model of the car need to be considered when budgeting for a replacement. For instance, a plastic engine splash shield for a 2007-2009 Toyota Camry costs $52.13, whereas a shield for a 2008-2015 Audi TT Base costs $76.73.

It is worth noting that some car owners have reported being quoted prices of over $400 for a plastic shield replacement from dealers, but it may be possible to find cheaper compatible parts online or at salvage yards.

Cost-saving options

If you're looking to save costs when replacing the plastic cover under your car, there are several options to consider:

Choose a Plastic Engine Splash Shield

Plastic engine splash shields are more affordable than metal shields, with an average replacement cost of $25 to $150. While plastic shields are more prone to breakage and may require more frequent replacements, they can still offer sufficient protection for everyday driving on regular roads.

Purchase Aftermarket Parts

Instead of buying OEM (Original Equipment Manufacturer) parts, consider purchasing aftermarket parts, which are often much cheaper and can function just as well. Online platforms like eBay, Amazon, and specialized aftermarket car parts websites offer a wide range of options for various car models.

Install the Shield Yourself

If you have some mechanical skills and the necessary tools, you may be able to install the plastic cover yourself. This can help you avoid labor costs, which typically range from $65 to $200. Online forums and tutorials can provide guidance on how to replace the plastic cover under your specific car model.

Check Salvage Yards

Salvage yards or junkyards are great places to find used car parts at a fraction of the cost of new ones. You can often find plastic engine splash shields in good condition from cars that are being scrapped or dismantled. This option may require some searching and negotiating skills, but it can lead to significant cost savings.

Hold the Responsible Party Accountable

If the damage to your plastic cover was caused by negligence during a service or repair, hold the responsible party accountable. For example, if an oil change shop failed to properly secure the plastic shield, they should be liable for the repair or replacement. In such cases, you may be able to avoid costs altogether by having them fix their mistake.

Removing the old cover

Removing the old plastic cover from under your car is a task that can be simple or complex, depending on the make and model of your car. It is important to note that the plastic shield under your car is there to keep debris and excessive moisture away from the engine and transmission components, and it also aids in proper cooling and improves fuel economy. While it is not critical to have this plastic cover, its absence may lead to a slight decline in mpg as it helps reduce drag.

Now, to remove the old plastic cover, you will need to get under your car and locate the screws and clips that hold the cover in place. Depending on your car's make and model, there may be just a few screws and clips, or there could be many. For example, the 2017 Mazda 3 has a splash shield that is divided into three sections, with the driver's side being relatively easy to access, while the passenger side is more challenging due to the presence of the washer bottle and other components.

Before removing any screws or clips, it is recommended to take note of their locations and perhaps even take a few photos with your phone so that you can remember how everything fits back together. Start by removing the screws with the appropriate tool, usually a screwdriver or a socket wrench. Be careful not to strip the heads of the screws, as this will make it difficult to remove them. If the screws are already stripped or damaged, you may need to use a different method, such as gripping the head of the screw with locking pliers and turning it counterclockwise to remove it.

After removing the screws, you may need to remove any push clips or hidden tabs that are holding the plastic cover in place. These can usually be removed by gently prying them off with a flat-head screwdriver or a similar tool. Be careful not to break the tabs, as this will create additional work for you when installing the new cover. Once all the screws and clips are removed, gently pull the old plastic cover away from the car. It may be necessary to wiggle it a bit to loosen any remaining attachments.

Installing the new cover

Installing the new plastic cover under your car is a straightforward process. Here's a step-by-step guide to help you get it done:

• Align the New Panel: Place the new plastic panel underneath your car, ensuring it is centred and level. Line up the fastener holes with the existing holes on your vehicle.
• Attach Centre Fasteners: Using your socket wrench or screwdriver, start attaching the fasteners one by one. Begin with the fasteners in the centre of the panel to secure it in place.
• Secure the Edges: Once the centre fasteners are in place, move towards the edges of the panel. Continue attaching the remaining fasteners as you work your way out. Make sure to pull the panel tight against the undercarriage to prevent any rattling or scraping sounds.
• Reinforce with Zip Ties or Bungee Cords (Optional): For added security, you can reinforce the panel with zip ties or bungee cords. This will help hold the panel in place and prevent it from vibrating or coming loose.
• Locate Attachment Points: Look for sturdy points on your car's undercarriage near the fastener points to attach the zip ties or bungee cords.
• Attach the Ties or Cords: Use pliers to tighten the zip ties or bungee cords around the plastic panel and the attachment points. Ensure they are snug but not overly tight to avoid damaging the panel.
• Test Drive: After installing the new panel, take your car for a test drive to ensure that there are no more rattling or scraping noises.

By following these steps, you can securely install the new plastic cover under your car, ensuring it is properly fastened and aligned. Remember to refer to your car's manual or seek advice from a professional mechanic if you have any doubts or encounter any issues during the installation process.

Testing the new cover

The cost of replacing the plastic cover under a car can vary widely. Some car owners have reported being quoted around $400 for a replacement, while others have found cheaper alternatives online. The price will depend on the car's make and model, as well as the availability of aftermarket parts.

Once you have acquired a replacement plastic under-engine cover, or engine splash shield, it is important to test it to ensure it is securely fastened. Firstly, locate the screws, bolts, and washers that keep the engine splash shield in place. Using a socket wrench or various screwdrivers, remove these fasteners and take off the old engine splash shield.

Next, place the new engine splash shield on your car, ensuring it is correctly aligned with the screw holes. Secure the new cover using the appropriate bolts, screws, and washers. It is important to use the correct type and size of fasteners to avoid damage to the new cover or the vehicle.

After installation, lower the vehicle to the ground and test-drive it to ensure the engine splash shield is adequately fastened. Drive on a variety of road surfaces, including smooth pavement and bumpy roads, to simulate real-world driving conditions. Listen for any unusual noises that may indicate a loose or improperly installed cover.

During and after the test drive, periodically inspect the engine splash shield to ensure it remains securely in place. Check for any signs of damage or wear, such as cracks, scratches, or loose fasteners. If the cover is not properly secured, stop driving and re-tighten the fasteners as necessary. It may be helpful to bring the vehicle to a mechanic for a professional inspection and advice.

By following these steps and conducting a thorough test, you can ensure that your new plastic under-engine cover is properly installed and securely fastened, providing protection for your vehicle's engine from road debris and potential damage.
