Side window deflectors are a highly sought-after accessory for Mitsubishi Outlander owners aiming to improve both the comfort and functionality of their vehicle. These deflectors, also known as rain guards or wind deflectors, allow you to keep your windows slightly open even during adverse weather conditions like rain or snow, without letting water or excessive wind noise enter the cabin. This not only improves ventilation but also reduces window fogging, enhances air circulation, and can add a sleek, customized look to your Outlander.

Benefits of Installing Side Window Deflectors on Your Mitsubishi Outlander

Before diving into how to choose and install side window deflectors, it’s worth exploring the key advantages they offer to Mitsubishi Outlander drivers:

  • Improved Ventilation: Window deflectors allow fresh air to circulate inside the vehicle while keeping rain and debris out. This is especially useful during hot summer days or when parked to prevent heat buildup.
  • Reduced Wind Noise: Deflectors help streamline airflow around your windows when driving with the windows slightly lowered, minimizing the annoying whistling or buffeting sounds common at higher speeds.
  • Protection from Rain and Snow: You can crack the windows during wet weather without worrying about water entering the cabin. This keeps the interior dry and comfortable.
  • Minimized Window Fogging: By promoting better airflow inside the vehicle, deflectors reduce condensation buildup on windows, improving driver visibility and safety.
  • Enhanced Aesthetics: Many window deflectors come in tinted or smoked finishes that complement the Outlander’s design, adding a subtle but sporty appearance.

Understanding Different Types of Side Window Deflectors

When shopping for side window deflectors for your Mitsubishi Outlander, it's important to know the types available on the market and how they differ in installation, durability, and functionality.

In-Channel (Clip-On) Deflectors

These deflectors fit directly into the window channel and are held in place by clips or snug fitment. They do not require adhesive, making them easier to remove or transfer to another vehicle. In-channel deflectors are often preferred by those who want a clean look without permanent modifications. However, installation can be a bit more involved as the window glass must be lowered to insert the deflector properly.

Stick-On (Adhesive) Deflectors

Stick-on deflectors use a strong 3M automotive adhesive tape to attach to the exterior window frame. They are generally simpler to install and do not require lowering the glass during installation. These deflectors provide a tight seal against the window frame and are highly durable, but they are more permanent and may leave adhesive residue if removed.

Vent Visors with Extended Coverage

Some models offer vent visors that extend further out from the window frame, providing enhanced protection from wind and rain. These can be slightly more noticeable but offer maximum functionality for drivers who frequently drive with windows cracked in harsh weather.

Factors to Consider When Choosing Side Window Deflectors for Your Mitsubishi Outlander

Selecting the right deflectors involves more than just picking a product labeled compatible with your Outlander. Here are essential factors to keep in mind:

  • Model Year Compatibility: Mitsubishi Outlander has undergone design changes across generations. Always verify that the deflectors are made specifically for your Outlander’s model year and trim to ensure a perfect fit without gaps or misalignment.
  • Material Quality and Finish: Look for deflectors constructed from high-quality acrylic or polycarbonate plastics that are UV-resistant and impact-resistant. A tinted or smoked finish not only enhances aesthetics but also reduces glare and sun exposure inside the vehicle.
  • Installation Method: Choose between clip-on or stick-on types based on your comfort level with installation and whether you want a more permanent or removable solution. Adhesive-backed deflectors offer easier installation but require careful surface preparation.
  • Durability and Warranty: Opt for brands that offer a warranty and have positive user reviews regarding durability in various weather conditions, including exposure to sun, rain, snow, and road debris.
  • Style and Profile: Decide if you want a slim, low-profile deflector that subtly blends with your Outlander’s lines or a more pronounced design that maximizes wind and rain deflection. Some users prefer a sportier look, while others want minimal visual impact.
  • Price and Brand Reputation: While it’s tempting to go for cheaper options, investing in reputable brands ensures you get quality materials and precise fitment. Brands like AVS, WeatherTech, and Mitsubishi Genuine Accessories are popular choices among Outlander owners.

Step-by-Step Guide to Installing Side Window Deflectors on a Mitsubishi Outlander

Installing side window deflectors on your Outlander is typically a straightforward process that most vehicle owners can complete at home with minimal tools and effort. Below is a detailed step-by-step guide to ensure your installation is clean, secure, and long-lasting.

Tools and Materials Needed

  • Side window deflectors (compatible with your Outlander model)
  • Rubbing alcohol or automotive surface cleaner
  • Clean microfiber cloths
  • Isopropyl alcohol wipes (for surface prep)
  • Masking tape (optional, for positioning)
  • Heat gun or hairdryer (optional, to warm adhesive tape for better bonding)

Installation Steps

  1. Prepare the Vehicle: Park your Mitsubishi Outlander on a flat surface in a shaded area to avoid direct sunlight, which can affect adhesive bonding. Make sure the windows are fully closed before beginning.
  2. Clean the Surface Thoroughly: Using rubbing alcohol or isopropyl alcohol wipes, clean the window frame area where the deflector will attach. Remove all dirt, dust, grease, and residues to ensure the adhesive sticks properly. Wipe dry with a clean microfiber cloth.
  3. Test Fit the Deflectors: Before peeling any adhesive backing, hold each deflector up to its corresponding window to check alignment and fit. This helps you visualize placement and avoid mistakes during final installation.
  4. Mark Placement (Optional): Use small pieces of masking tape to mark the ends or edges of the deflector on the window frame for precise positioning during installation.
  5. Apply Heat to Adhesive Tape (If Recommended): Some adhesive-backed deflectors benefit from warming the tape slightly with a heat gun or hairdryer to activate the adhesive and improve bonding. Follow manufacturer instructions closely.
  6. Remove Adhesive Backing: Carefully peel off the protective backing from the adhesive tape on the deflector, avoiding touching the adhesive surface with your fingers.
  7. Attach the Deflector: Align the deflector with your reference marks and press it firmly onto the window frame, starting from one end and working your way to the other. Apply even pressure along the entire length to ensure full contact.
  8. Secure and Cure: Hold the deflector in place for a few minutes to set initial adhesion. Avoid rolling down the windows or washing the vehicle for at least 24 to 48 hours to allow the adhesive to cure fully.
  9. Repeat for All Windows: Install deflectors on all side windows as desired, following the same procedure for each.

Tips for a Successful Installation

  • Perform installation in moderate temperatures (ideally between 60°F and 80°F) to maximize adhesive effectiveness.
  • Do not rush the cleaning and preparation steps; a clean surface is critical for long-lasting adhesion.
  • If you choose clip-on deflectors, lower the window slightly during installation to insert the deflector into the channel properly, then raise the window to secure it.
  • Inspect the deflectors periodically for any lifting or damage, especially after extreme weather, and re-secure or replace as necessary.

Maintaining Your Side Window Deflectors

Once installed, proper maintenance will extend the life and appearance of your side window deflectors:

  • Regular Cleaning: Clean the deflectors gently with mild soap and water using a soft cloth. Avoid abrasive cleaners or scrubbing pads that can scratch the surface.
  • Protect from Harsh Chemicals: Avoid contact with strong solvents or petroleum-based products that can degrade the plastic and adhesive.
  • Check Adhesion: Periodically inspect the edges for any signs of peeling or lifting. Reapply adhesive or replace deflectors if necessary.
  • Winter Care: In snowy climates, remove ice and snow carefully from deflectors to avoid cracks or damage.
