Hey guys! Thinking about taking your Jeep Cherokee XJ diesel off-road and through some serious water crossings? Then you're definitely going to want to consider installing a snorkel. A snorkel isn't just a cool-looking accessory; it's a functional upgrade that can protect your engine from water damage and improve its overall performance. In this article, we'll dive deep into everything you need to know about Jeep Cherokee XJ diesel snorkels. We'll cover why you need one, what to look for when buying, how to install it, and even some of the best options on the market.

Why You Need a Snorkel for Your Jeep Cherokee XJ Diesel

Let's get straight to the point: water and diesel engines don't mix. Your Jeep Cherokee XJ diesel is a beast, but it's not invincible. The factory air intake is typically located in the engine bay, which is vulnerable to water ingress during deep water crossings, heavy rain, or even muddy conditions. When water gets sucked into your engine, it can lead to a catastrophic event known as hydrolock. Hydrolock occurs when water fills the cylinders, preventing the pistons from compressing. This can bend connecting rods, crack the engine block, and cause all sorts of expensive damage.

A snorkel relocates the air intake to a higher point, usually at roof level. This ensures that your engine breathes clean, dry air even when the lower parts of your Jeep are submerged. By raising the air intake, you dramatically reduce the risk of hydrolock and keep your engine running smoothly. Beyond water protection, a snorkel can also improve your engine's performance. The higher intake point often means the engine breathes cooler and cleaner air, free from the dust and debris that typically swirl around at ground level. Cooler air is denser, which means more oxygen for combustion, potentially leading to a slight increase in horsepower and fuel efficiency. A snorkel provides peace of mind when you're out on the trails. Knowing that your engine is protected from water damage allows you to tackle challenging terrains with confidence. You won't have to worry about shallow puddles turning into engine-killing obstacles. This added security enhances your off-roading experience and allows you to push your Jeep to its limits. For diesel engines, which are more susceptible to water damage due to their higher compression ratios, a snorkel is an especially vital investment.

Choosing the Right Snorkel for Your Jeep Cherokee XJ Diesel

Okay, so you're convinced you need a snorkel. Awesome! But with so many options available, how do you choose the right one for your Jeep Cherokee XJ diesel? Here are some key factors to consider:

• Material: Snorkels are typically made from either high-quality polyethylene (HDPE) or steel. HDPE snorkels are lightweight, durable, and resistant to UV damage. They're also generally more affordable. Steel snorkels, on the other hand, are incredibly strong and offer excellent protection against impacts. However, they're heavier and more prone to rust if not properly coated. Consider the type of off-roading you'll be doing and choose a material that suits your needs. For most recreational off-roaders, an HDPE snorkel will be more than sufficient. However, if you're planning on tackling extreme trails with potential for rock crawling, a steel snorkel might be a better choice.
• Design and Fitment: Make sure the snorkel is specifically designed for the Jeep Cherokee XJ. Universal snorkels might work, but they often require extensive modifications and may not fit properly. A snorkel designed for your vehicle will ensure a seamless installation and optimal performance. Consider the snorkel's design and how it integrates with your Jeep's aesthetics. Some snorkels have a sleek, low-profile design, while others are more aggressive and stand out. Choose a design that you like and that complements your Jeep's overall look. Also, check for the snorkel's air ram design. Some snorkels have a forward-facing air ram, while others have a reversible one. A reversible air ram allows you to turn it backward in dusty conditions to prevent dust from entering the intake.
• Airflow: The snorkel should provide adequate airflow to your diesel engine. A poorly designed snorkel can restrict airflow, which can negatively impact performance. Look for a snorkel that has a large diameter intake tube and a smooth internal design to minimize airflow restrictions. Some manufacturers provide airflow specifications, so be sure to check those before making a purchase. A snorkel with a larger air ram will generally provide better airflow, but it might also be more prone to catching on branches.
• Installation: Consider your mechanical skills and choose a snorkel that you're comfortable installing. Some snorkels are designed for easy, DIY installation, while others require more advanced modifications and may be best left to a professional. Read reviews and watch installation videos to get a sense of the complexity involved. If you're not comfortable drilling holes in your Jeep's body, you might want to opt for a snorkel that can be installed with minimal modifications. Some snorkels come with detailed instructions and all the necessary hardware, while others require you to source additional parts. Make sure you know what you're getting into before you start the installation process.

Step-by-Step Guide to Installing Your Jeep Cherokee XJ Diesel Snorkel

Alright, you've got your snorkel, and you're ready to get it installed. Here's a general step-by-step guide to help you through the process. Keep in mind that the exact steps may vary depending on the specific snorkel kit you purchased, so always refer to the manufacturer's instructions first.

1. Preparation: Gather all the necessary tools and materials. You'll typically need a drill, various drill bits, a hole saw, a screwdriver set, a wrench set, safety glasses, gloves, a marker, and masking tape. Disconnect the negative battery terminal to prevent any electrical accidents. Read the snorkel's installation instructions thoroughly before you begin. This will give you a clear understanding of the process and help you avoid any mistakes. Park your Jeep on a level surface and ensure you have adequate lighting.
2. Remove the Existing Airbox: Disconnect the air intake hose from the factory airbox. Loosen any clamps or fasteners that secure the airbox in place. Carefully remove the airbox from the engine bay. Some airboxes may be bolted to the inner fender, so be sure to remove those bolts as well. Clean the area where the airbox was located to remove any dirt or debris.
3. Mark and Drill Holes: Using the snorkel template provided in the kit, carefully mark the locations for the holes you'll need to drill on the fender. Use masking tape to protect the paint around the marked areas. Double-check your measurements to ensure accuracy. Use a center punch to create a small indentation at each marked location. This will help prevent the drill bit from wandering. Start with a small pilot hole and gradually increase the size of the drill bit until you reach the required diameter. Use a hole saw to drill any large holes required for the snorkel's mounting studs or intake tube. Deburr the edges of the holes to prevent any sharp edges from damaging the snorkel or your Jeep's paint.
4. Install the Snorkel Body: Apply a bead of sealant around the edges of the holes you drilled. Carefully position the snorkel body on the fender, aligning it with the drilled holes. Insert the snorkel's mounting studs through the holes and secure them with nuts and washers. Tighten the nuts to the specified torque. Connect the snorkel's intake tube to the engine's air intake system. Use clamps to secure the connection and ensure a tight seal. Double-check all connections to ensure they are secure and leak-free.
5. Install the Air Ram: Attach the air ram to the top of the snorkel body. Secure it with the provided hardware. Ensure the air ram is facing forward (or backward in dusty conditions). Tighten all connections to ensure the air ram is securely attached. Inspect the entire installation to ensure everything is properly aligned and tightened. Reconnect the negative battery terminal.
6. Test and Inspect: Start the engine and listen for any unusual noises or air leaks. Check the snorkel's connections for any signs of leaks or loose fittings. Take your Jeep for a short test drive to ensure the snorkel is functioning properly. Monitor your engine's performance to ensure it's not being negatively affected by the snorkel. If you notice any issues, re-check your installation and consult the manufacturer's instructions.
