We’ll walk you through the incredible benefits, how to choose the right kit, the tools you’ll need, and a step-by-step installation process. Get ready to conquer the mud without breaking a sweat.
Why Bother? The Undeniable Benefits of Polaris Scrambler Radiator Relocation
You might be thinking, “Is this mod really necessary?” If you stick to gravel roads, maybe not. But if you live for the deep stuff, it’s one of the most crucial upgrades you can make. Here are the core benefits of moving that rad up and out of the way.
Benefit #1: Eliminate Overheating in Mud and Water
This is the number one reason riders perform this upgrade. The stock radiator sits low and exposed, right in the line of fire for mud, dirt, and water. When the fins get caked, air can no longer pass through to cool the coolant.
By moving the radiator up onto the front rack, you lift it out of the muck. This ensures a constant, clean flow of air, keeping your engine at its optimal operating temperature no matter how nasty the terrain gets. It’s the difference between powering through a mud pit and getting towed out of one.
Benefit #2: Superior Radiator Protection
Your radiator is a delicate piece of equipment. In its factory location, it’s vulnerable to impacts from rocks, sticks, and other trail debris that can easily puncture the core or damage the fins.
A relocation kit moves it to a much safer position, shielded by a heavy-duty steel or aluminum frame. Think of it as armor for your ATV’s cooling system. This added protection can save you from a costly trailside failure.
Benefit #3: Simplified Cleaning and Maintenance
Tired of spending an hour with a pressure washer trying to blast hardened mud out of your radiator fins after every ride? A relocated radiator makes cleanup a breeze.
Instead of being buried behind plastic and framework, it’s right on top and easy to access. A quick spray with a hose is often all it takes to get it looking and performing like new. This also makes routine inspections for leaks or damage incredibly simple, which is a key part of our polaris scrambler radiator relocation care guide.
Choosing Your Weapon: How to Select the Right Relocation Kit
Not all kits are created equal. When you’re ready to buy, you’ll find a few different options on the market. Making the right choice depends on your budget, riding style, and future modification plans. Here’s what to look for.
Material and Construction
Most kits are made from either steel or aluminum. Steel kits are typically more affordable and extremely durable, but they are heavier. Aluminum kits are lighter, which is great for performance, and they won’t rust, but they usually come with a higher price tag.
Look for kits with quality welds and a durable powder-coated finish to resist corrosion and stand up to abuse on the trail.
Design and Features
Consider the design. Does the kit angle the radiator for better airflow and a more aggressive look? Some kits, like those from High Lifter or Wild Boar ATV Parts, are engineered to work seamlessly with snorkel kits, often providing pre-cut holes or mounting points.
If you plan on adding snorkels later, choosing a compatible radiator relocation kit now will save you a lot of headaches down the road. This is one of the most important polaris scrambler radiator relocation tips we can offer.
The Pre-Flight Checklist: Tools and Parts You’ll Need
Before you turn a single wrench, get all your ducks in a row. Having the right tools and supplies on hand makes the job go smoothly and prevents frustrating trips to the auto parts store mid-install.
Essential Tools:
- A good socket and ratchet set (metric)
- Wrench set (metric)
- Hose clamp pliers (or flathead screwdriver/socket for worm-gear clamps)
- Side cutters or wire snips
- Zip ties
- A large drain pan
- A funnel
- Utility knife or hose cutter
- Drill and drill bits (some kits may require minor drilling)
Essential Parts & Supplies:
- Your chosen Polaris Scrambler radiator relocation kit (includes brackets, hoses, clamps, and hardware)
- 1 gallon of new ATV-specific coolant (don’t reuse the old stuff!)
- Distilled water (for mixing with coolant if it’s not pre-mixed)
- Thread locker (like Loctite Blue) for key bolts
The Main Event: Your Step-by-Step Polaris Scrambler Radiator Relocation Guide
Alright, it’s go-time. Park your Scrambler on a level surface and make sure the engine is completely cool before you start. A hot cooling system is under pressure and can cause serious burns. Safety first, always.
Step 1: Drain the Coolant
First, remove the front plastics and grill to get access to the radiator. Place your drain pan under the ATV. Locate the radiator cap and remove it—this will help the coolant drain faster.
Next, find the lowest point on the cooling system, which is usually the bottom radiator hose. Use your hose clamp pliers to loosen the clamp and gently pull the hose off the radiator spout. Let all the coolant drain into the pan. This is a good time to think about eco-friendly polaris scrambler radiator relocation by ensuring you capture and dispose of the old coolant properly at a local recycling center.
Step 2: Disconnect and Remove the Stock Radiator
With the system empty, you can now disconnect the remaining hoses and the fan’s electrical connector. The fan connector has a small tab you’ll need to press to release it.
Now, unbolt the radiator from its stock mounts. It’s usually held on by just a few bolts. Carefully lift the radiator and fan assembly out of the ATV. Take a moment to transfer the fan from the old radiator to its new position on the relocation kit’s bracket, following the kit’s instructions.
Step 3: Install the New Mounting Bracket
This is where your kit’s instructions are king. Most kits will mount directly to your Scrambler’s front rack. You’ll use the provided hardware to bolt the main support brackets into place.
Take your time to ensure everything is aligned and square before fully tightening the bolts. Using a bit of thread locker on the mounting bolts is a great pro-tip to prevent them from vibrating loose on the trail.
Step 4: Mount the Radiator and Route the New Hoses
Attach your radiator (with the fan now installed on it) to the new bracket. Now comes the most critical part of this how to polaris scrambler radiator relocation process: running the new, longer coolant hoses.
Route the hoses from the engine up to the newly positioned radiator. Pay close attention to avoid sharp bends or kinks that could restrict flow. Keep the hoses away from hot exhaust components and any moving parts like the steering stem. Use zip ties to secure the hoses neatly to the frame.
Step 5: Fill and Bleed the Cooling System
With everything connected, it’s time to refill the system. Place a funnel in the radiator filler neck and slowly pour in your 50/50 mix of new coolant and distilled water until it’s full.
Now, you must “burp” or bleed the air out of the system. Leave the radiator cap off, start the engine, and let it idle. You’ll see air bubbles coming up through the coolant. As the level drops, slowly add more coolant to keep it topped off. It can help to gently squeeze the radiator hoses to help move air pockets along. Once the fan cycles on and off and you no longer see bubbles, the system is bled. Top it off one last time and securely install the radiator cap.
Avoiding Trailside Tragedies: Common Problems and Best Practices
An installation is only as good as its weakest point. Following these polaris scrambler radiator relocation best practices will help you avoid the most common problems with this mod.
Problem: Leaks at Hose Connections
Solution: The most common issue is a small leak from a hose clamp. Always use high-quality clamps (many kits provide them) and ensure they are snug. Don’t overtighten and damage the hose, but make sure it’s secure. After your first ride, re-check all clamps as the hoses may settle.
Problem: Pinched or Kinked Hoses
Solution: This is a critical failure point. A kinked hose restricts coolant flow and will cause overheating just as bad as a mud-packed radiator. During installation, carefully plan your hose routing. If you have to make a tight bend, consider using a 45 or 90-degree brass fitting to create a smooth turn.
Problem: Fan Wiring Issues
Solution: You’ll be extending the fan’s wiring harness. Ensure you use proper weatherproof connectors and solder/heat-shrink the connections. Don’t just twist wires together and wrap them in electrical tape. Protect the extended wiring in a loom and secure it away from potential pinch points.
Post-Install Care and Sustainable Riding
Your new setup is built for abuse, but a little care goes a long way. This simple polaris scrambler radiator relocation care guide ensures longevity.
After every ride, give the radiator a quick rinse to remove any dust or light mud. Periodically inspect the coolant hoses for any signs of rubbing, cracking, or bulging. Check your coolant level in the overflow bottle before each ride.
By keeping your machine running efficiently and properly disposing of old fluids, you’re practicing a more sustainable polaris scrambler radiator relocation and ownership lifestyle. A well-maintained ATV is a more reliable and eco-friendly one.
Frequently Asked Questions About Polaris Scrambler Radiator Relocation
Will a radiator relocation kit void my Polaris warranty?
