So, you're thinking about adding a snorkel to your Jeep Cherokee XJ diesel? Awesome! Let's dive into why that's a fantastic idea and how to make it happen. A snorkel isn't just for show; it's a practical upgrade that can seriously enhance your off-roading capabilities, especially if you're rocking a diesel engine. Whether you're planning to ford deep streams, tackle dusty trails, or just want to give your XJ a more aggressive look, a snorkel is a mod worth considering. In this article, we'll cover everything from the benefits of installing a snorkel to a step-by-step guide on how to get it done. So, buckle up, and let's get started!

Why Install a Snorkel on Your Jeep Cherokee XJ Diesel?

Okay, let's get straight to the point: why should you even bother with a snorkel? Well, there are several compelling reasons, especially for a diesel-powered XJ.

• Water Fording: This is the most obvious benefit. A snorkel raises your engine's air intake point, allowing you to drive through deeper water without sucking water into your engine. Water in your engine? That's a recipe for disaster, leading to hydrolock, which can seriously damage your engine. With a snorkel, you can confidently tackle water crossings that would otherwise be off-limits.
• Dust and Debris: Off-roading often means kicking up a lot of dust and debris. A snorkel can help pull cleaner air from higher up, away from the dust cloud created by your tires. This is especially important for diesel engines, which are more sensitive to dirty air. Cleaner air means better combustion, improved engine performance, and longer air filter life. Think of it as a dust shield for your engine.
• Improved Airflow: Some snorkels are designed to improve airflow to the engine. By providing a more direct and less restrictive path for air to enter, a snorkel can boost horsepower and torque. This is particularly noticeable at higher RPMs. While the gains might not be huge, every little bit helps, right? Plus, the improved airflow can also contribute to better fuel economy.
• Cooler Air Intake: The air higher above the ground is often cooler than the air swirling around the engine bay. Cooler air is denser, which means it contains more oxygen. More oxygen equals better combustion and increased power. It's like giving your engine a breath of fresh, crisp mountain air.
• Aggressive Look: Let's be honest, snorkels look cool! They give your XJ a rugged, adventure-ready appearance. It's a visual upgrade that tells everyone you're serious about off-roading. Plus, it's a great conversation starter. Be prepared for people to ask you about it.

Choosing the Right Snorkel Kit

Alright, so you're sold on the idea of a snorkel. The next step is choosing the right kit for your XJ. With so many options out there, it can be a bit overwhelming. Here’s what to consider:

• Material: Snorkels are typically made from either polyethylene or stainless steel. Polyethylene is a durable plastic that's resistant to impacts and UV radiation. It's also relatively lightweight. Stainless steel is incredibly strong and offers a more rugged look. However, it's heavier and can be more expensive. Consider your budget and the type of terrain you'll be tackling.
• Design: Snorkels come in various designs. Some follow the A-pillar of your windshield, while others run along the side of your hood. Choose a design that you like and that fits well with the overall look of your XJ. Also, consider the snorkel's air intake. Some have a simple open end, while others have a pre-filter to catch large debris.
• Compatibility: Make sure the snorkel kit is specifically designed for your Jeep Cherokee XJ and, ideally, for diesel models. While some kits might be universal, a custom-fit kit will ensure a proper seal and easier installation. Double-check the product description and read reviews from other XJ owners.
• Installation: Some snorkel kits are easier to install than others. If you're not comfortable cutting into your XJ's body, look for a kit that requires minimal modification. Also, check if the kit includes detailed instructions and all the necessary hardware.
• Price: Snorkel kits can range in price from a few hundred dollars to over a thousand. Set a budget and stick to it. Remember, the most expensive kit isn't always the best. Read reviews and compare features to find the best value for your money.

Step-by-Step Installation Guide

Okay, you've got your snorkel kit. Now it's time to get your hands dirty! Here's a general guide to installing a snorkel on your Jeep Cherokee XJ. Keep in mind that the exact steps may vary depending on the specific kit you purchased, so always refer to the manufacturer's instructions.

Tools You'll Need

Before you start, gather all the necessary tools. This will make the installation process much smoother. Here's a list of what you'll likely need:

• Drill with various drill bits
• Hole saw (usually included with the snorkel kit)
• Screwdrivers (Phillips and flathead)
• Socket set
• Wrench set
• Measuring tape
• Marker or grease pencil
• Safety glasses
• Gloves
• Cutting tool (e.g., jigsaw or angle grinder)
• Rust-resistant primer and paint
• Silicone sealant

Step 1: Preparation

• Read the Instructions: Seriously, read them! Familiarize yourself with all the steps and components of the snorkel kit. This will prevent headaches later on.
• Disconnect the Battery: Safety first! Disconnect the negative terminal of your battery to avoid any electrical mishaps.
• Remove the Airbox: You'll need to remove the factory airbox to access the fender and inner fender. Disconnect the air intake hose and any sensors attached to the airbox, then unbolt it and remove it from the engine bay.
• Prepare the Fender: This is where things get a little scary. You'll need to cut a hole in your fender to accommodate the snorkel. Use the template provided with the kit to mark the location of the hole. Double-check your measurements before you start cutting!

Step 2: Cutting the Fender

• Drill a Pilot Hole: Drill a small pilot hole in the center of the marked area. This will help guide your cutting tool.
• Cut the Hole: Using a jigsaw or angle grinder with a cutting wheel, carefully cut along the marked line. Take your time and avoid rushing. It's better to cut too little than too much. Wear safety glasses to protect your eyes from flying debris.
• Deburr the Edges: Use a file or sandpaper to smooth out the edges of the cut hole. This will prevent sharp edges from damaging the snorkel or causing injury.
• Apply Primer and Paint: Apply a rust-resistant primer and paint to the cut edges of the fender. This will prevent rust and corrosion.

Step 3: Installing the Snorkel

• Attach the Snorkel Body: Insert the snorkel body through the hole in the fender. Align it properly and secure it with the provided hardware. Use silicone sealant to create a waterproof seal between the snorkel and the fender.
• Connect the Air Duct: Connect the snorkel's air duct to the engine's air intake. This may involve removing or modifying the factory air intake hose. Make sure the connection is secure and airtight.
• Secure the Snorkel to the A-Pillar: Most snorkels are secured to the A-pillar of the windshield with brackets. Attach the brackets to the snorkel and the A-pillar, then tighten the bolts. Be careful not to overtighten the bolts, as this could damage the A-pillar.
• Reinstall the Airbox: Reinstall the factory airbox, making sure all connections are secure. Reconnect the air intake hose and any sensors that were attached to the airbox.

Step 4: Final Checks

• Inspect All Connections: Double-check all connections to ensure they are tight and secure. Look for any leaks or gaps.
• Reconnect the Battery: Reconnect the negative terminal of the battery.
• Test the Engine: Start the engine and listen for any unusual noises. Check for any air leaks around the snorkel and air intake connections.

Maintenance Tips for Your Snorkel

• Regular Inspections: Periodically inspect your snorkel for any signs of damage or wear. Check for cracks, leaks, or loose connections. Address any issues promptly to prevent further damage.
• Cleaning: Clean your snorkel regularly to remove dirt, dust, and debris. Use a mild soap and water solution to wash the exterior of the snorkel. For the air intake, use a vacuum cleaner or compressed air to remove any debris.
• Sealing: Check the silicone sealant around the snorkel's base and any other connections. If you notice any cracks or gaps, reapply sealant to maintain a waterproof seal.
• Filter Maintenance: If your snorkel has a pre-filter, clean or replace it regularly. This will help maintain optimal airflow and prevent debris from entering your engine.
