Gearing Up: Tools and Parts for the Job
Before you turn the first wrench, a little preparation goes a long way. Having the right tools and parts laid out makes the entire process smoother and helps you avoid mid-project trips to the auto parts store.
Essential Tools You’ll Need
Most of this job can be done with a standard set of mechanic’s tools. You likely have most of these in your garage already.
- Socket Set (Metric) with extensions
- Wrenches (Metric)
- Hose Clamp Pliers or a Flathead Screwdriver/Socket Driver
- Drill and a Hole Saw Kit (for dash vents)
- Utility Knife or a good hose cutter
- Interior Trim Removal Tool Kit (highly recommended to prevent scratches)
- Large Drain Pan for coolant
- Funnel (a spill-free coolant funnel is a lifesaver)
- Zip Ties and Electrical Tape
- Safety Glasses and Gloves
Choosing Your Heater Kit: OEM vs. Aftermarket
You have two main paths here: the official Polaris OEM kit or a quality aftermarket brand like Inferno Cab Heaters or Ice Crusher. There’s no single “best” answer, as it depends on your budget and priorities.
The Polaris OEM kit is designed for a perfect fit and typically comes with very detailed, model-specific instructions. However, it’s often the most expensive option.
Aftermarket kits from reputable brands offer fantastic performance, often at a lower price point. Their instructions might be slightly more generic, but they provide excellent value and are the go-to choice for many DIYers.
The Complete Polaris Xpedition Heater Install Guide
Alright, it’s time to get to work. This is the core of our polaris xpedition heater install guide. We’ll break it down into manageable steps. Take your time, read each step before you start it, and keep your parts organized.
Step 1: Safety First & Prep Work
Before you do anything else, prioritize safety. Park your Xpedition on a level surface and ensure the engine is completely cool. Never work on a hot cooling system.
Disconnect the negative terminal on your battery to prevent any electrical shorts. Then, place your drain pan under the front of the machine and partially drain the coolant from the radiator. You don’t need to drain it all, just enough to get the level below where you’ll be cutting the main hoses.
Step 2: Gaining Access – Removing Panels
To get to the mounting location and run your hoses, you’ll need to remove some plastic. Using your trim removal tools, carefully pop off the necessary dash panels and the center console cover. You will also likely need to remove the front hood panel to access the radiator hoses.
Take pictures as you go and keep all your screws and clips in a magnetic tray or labeled bags. This will make reassembly a breeze.
Step 3: Mounting the Heater Core
The heater core is the main unit that contains the small radiator and fan. Your kit’s instructions will show the specific mounting location, which is typically high up under the passenger-side dashboard.
Hold the unit in place, mark your drill points, and securely mount it using the provided brackets and hardware. Ensure it’s snug and won’t vibrate.
Step 4: Tapping into the Coolant System
This is the most critical step. You’ll be splicing into the Xpedition’s main coolant lines to divert hot coolant to your new heater core. Identify the supply and return lines as indicated in your kit’s instructions.
Find a straight section in the hose, make a clean cut with your utility knife, and insert the provided Y-fittings. Double-check the orientation. Secure each connection with the provided hose clamps and make them snug. A loose clamp here will result in a leak.
Step 5: Routing the Heater Hoses
Now, run the new heater hoses from the Y-fittings in the engine bay to the inlet and outlet ports on the heater core you just mounted. Route them carefully to avoid sharp edges, moving parts, or hot exhaust components.
You will need to pass them through the firewall. Use the provided grommet to protect the hoses and create a clean, weatherproof seal.
Step 6: Installing Vents and Ducting
This is where you get to customize your heat flow. Using the correct size hole saw, carefully cut openings in your dash for the defrost and floor vents. Measure twice, cut once!
Clean up the edges and install the louvered vents. Attach the flexible ducting from the outlets on the heater core to the back of each new vent, securing them with zip ties.
Step 7: Wiring the System
The wiring is usually straightforward. Mount the fan speed switch in a convenient spot on your dash. The wiring harness will have a positive and a negative lead.
Connect the negative wire to a solid chassis ground. For the positive wire, use the Polaris Pulse Bar under the hood. This provides a key-on accessory power source that’s already fused and is the cleanest way to wire accessories.
Step 8: Refilling and Bleeding the Coolant
Do not skip this step! An air bubble in your cooling system can cause overheating. Re-attach any coolant hoses you disconnected and close the radiator drain.
Using a spill-free funnel, slowly refill the radiator with a 50/50 mix of coolant and distilled water. Start the engine with the radiator cap off and the heater on full blast. You’ll see bubbles coming up through the funnel—this is the air escaping. Keep adding coolant until the bubbles stop and the level is stable. This is one of the most vital polaris xpedition heater install tips for success.
Common Problems with Polaris Xpedition Heater Install (And How to Fix Them)
Even the best DIYer can hit a snag. Here are a few common issues and how to troubleshoot them, turning potential frustration into a quick fix.
Problem: My Heater Doesn’t Get Hot
This is almost always caused by air trapped in the system. The system needs more bleeding. Try parking the UTV on a steep incline with the nose up to help the air travel to the radiator. Let it run and continue to “burp” the system. Also, double-check that your coolant hoses aren’t kinked.
Problem: I See a Coolant Leak!
Don’t panic. Shut the engine off immediately. The most likely culprit is a loose hose clamp. Go back and check every single clamp you installed, especially on the Y-fittings. Give them another quarter-turn. If a leak persists, check the hose itself for any small nicks from the installation process.
Problem: The Fan Doesn’t Turn On
This is an electrical issue. Start with the simplest solution: check your fuse. If the fuse is good, use a multimeter to verify you have 12-volt power at the switch and at the fan motor itself. Often, the issue is a poor ground connection.
Best Practices for a Sustainable and Eco-Friendly Install
Being an off-roader means respecting the environment we love to play in. A sustainable polaris xpedition heater install is easy to achieve with a little mindfulness.
When you drain your coolant, capture every drop in a clean drain pan. Coolant (ethylene glycol) is highly toxic to animals and the environment. Never dump it on the ground. Take it to your local auto parts store or municipal recycling center; they will accept it for free.
Furthermore, an eco-friendly polaris xpedition heater install involves choosing quality parts that are built to last. A well-made heater kit won’t need to be replaced, reducing waste in the long run.
Long-Term Care: Your Polaris Xpedition Heater Install Care Guide
Your new heater is a low-maintenance component, but a little attention will ensure it works perfectly for years. This simple polaris xpedition heater install care guide is all you need.
Once a season, do a quick visual inspection. Check that the hose clamps are still tight and look for any signs of cracking or bulging on the heater hoses. When you perform regular coolant flushes on your Xpedition, your heater system will benefit as well, preventing internal corrosion.
Frequently Asked Questions About Polaris Xpedition Heater Install
How long does a Polaris Xpedition heater install take?
For a first-timer taking their time, plan for about 4 to 6 hours. An experienced mechanic might do it in 3. The key is not to rush, especially when cutting hoses and bleeding the coolant system.
Can I install a heater without draining all the coolant?
Yes, you can often get away with a partial drain, just enough to lower the coolant level below the hoses you need to cut. However, be prepared for some spillage. A full drain and fill is the cleanest method and a good opportunity to put fresh coolant in your machine.
Will installing an aftermarket heater void my Polaris warranty?
In the United States, your warranty is protected by the Magnuson-Moss Warranty Act. A manufacturer cannot void your entire vehicle warranty just because you installed an aftermarket part. They would have to prove that the specific aftermarket part you installed directly caused the failure of a warrantied component.
What’s the hardest part of the installation?
Most DIYers find that the two trickiest parts are cleanly tapping into the factory coolant lines without making a mess and thoroughly bleeding the air out of the system afterward. Patience is your best tool for both tasks.
With this guide, you’re fully equipped to tackle this project and unlock a whole new season of adventure. The warmth and comfort a heater provides on a cold day are truly game-changing.
Now get out there and conquer the cold. Ride safe, stay warm, and we’ll see you on the trail!
