What Makes the 2020 COD Polaris Sportsman 850 High Lifter a Mud-Slinging Legend?
Before we turn a wrench, it’s crucial to understand why your machine is so special. This isn’t a standard Sportsman with a lift kit slapped on. Polaris and High Lifter Engineering collaborated to build this rig from the ground up for one purpose: conquering mud.
Understanding these factory upgrades helps you appreciate the machine and know where to focus your maintenance efforts. The benefits of a 2020 cod polaris sportsman 850 high lifter are engineered right into its DNA.
Factory-Installed Muscle: Radiator Relocation and Snorkels
The most obvious feature is the high-mounted radiator and snorkel system. Moving the radiator out of the traditional front position keeps it from getting caked with mud and overheating. The snorkels ensure your engine and clutch breathe clean, dry air even when you’re fender-deep in water.
This setup is your rig’s lifeline in the slop. Keeping it clean and clear is non-negotiable for engine health.
High-Clearance A-Arms and Stiffer Springs
Look underneath and you’ll see arched A-arms. These aren’t just for looks; they provide critical ground clearance, allowing you to crawl over logs and rocks that would hang up a standard ATV. The suspension also features stiffer springs to handle the added weight of mud and prevent bottoming out.
The Power of the ProStar 850 Engine
At its heart is the 78-horsepower ProStar 850 twin-cylinder engine. It’s tuned for low-end torque, giving you the grunt needed to turn those big 29.5-inch High Lifter Outlaw 2 tires through the thickest peanut butter mud you can find.
Your Essential 2020 COD Polaris Sportsman 850 High Lifter Care Guide
A machine designed for extreme conditions demands a rigorous maintenance schedule. Sticking to this routine is the single best thing you can do for reliability and longevity. This is your go-to 2020 cod polaris sportsman 850 high lifter care guide.
Pre-Ride Inspection: The 5-Minute Lifesaver
Never, ever skip the pre-ride check. It can be the difference between a great day of riding and a long walk back to the truck. This is one of our most important 2020 cod polaris sportsman 850 high lifter tips.
- Tires & Wheels: Check for proper inflation (typically 5-7 PSI, but adjust for terrain) and look for any cuts or damage. Grab each tire and check for wheel bearing play.
- Fluids: Quickly check your engine oil and coolant levels. Look for any drips or leaks on the garage floor.
- Axles & Boots: Glance at all four CV boots. A tiny tear can quickly destroy an expensive axle if packed with grit and water.
* Controls: Test your throttle, brakes, and steering. Ensure smooth operation with no binding.
Post-Mud Wash Down: More Than Just Looks
Washing your High Lifter is not about vanity; it’s about preventative maintenance. Dried, caked-on mud is an abrasive that wears out bushings, bearings, and seals. It also traps moisture, leading to rust and corrosion.
Use a pressure washer, but be smart. Avoid blasting directly at electrical connections, bearings, or seals. Focus on cleaning the radiator, suspension components, and undercarriage. A clean machine is an easy machine to inspect and work on.
Fluid Checks and Changes
Your High Lifter’s fluids are its lifeblood. Use high-quality fluids specified by Polaris, like their PS-4 engine oil and Demand Drive fluid for the front differential.
- Engine Oil: Change it more frequently than the manual suggests, especially if you ride in deep water. Milky, coffee-colored oil is a sign of water contamination and requires an immediate change.
- Differential & Transmission Fluids: These are often neglected. Check them regularly for water intrusion. If the fluid looks milky, change it immediately.
- Coolant: Keep an eye on the reservoir for the high-mounted radiator. Ensure it’s topped off with the correct 50/50 antifreeze mix.
How to Troubleshoot Common Problems with the 2020 COD Polaris Sportsman 850 High Lifter
Even the toughest machines have their quirks. Knowing the common problems with a 2020 cod polaris sportsman 850 high lifter helps you diagnose issues quickly and get back on the trail. Here’s a quick guide on how to 2020 cod polaris sportsman 850 high lifter troubleshooting.
Overheating: Beyond the Mud
Yes, the radiator is relocated, but it can still overheat. The number one cause is a radiator packed with dried mud and debris. Even after washing, fine silt can remain between the cooling fins.
Pro Tip: Use a garden hose with a gentle spray nozzle from the backside of the radiator to push debris out the way it came in. Also, check that the radiator fan is kicking on. If not, you may have a bad fan, relay, or fuse.
Electrical Gremlins and Battery Care
Mud and water are enemies of electrical systems. Keep your battery terminals clean and tight. Apply dielectric grease to major electrical connectors to help keep water out.
If your pod lights are flickering or the winch is acting up, start by checking your battery voltage and grounds. A weak battery can cause a host of strange issues.
CV Joint and Axle Woes
The big tires and harsh conditions put a lot of stress on your axles. The first sign of a failing CV joint is a clicking sound when turning. This is usually caused by a torn boot that allowed dirt and water to destroy the joint’s internal bearings.
Inspect your CV boots before every ride. If you find a tear, you can often save the axle by cleaning, re-greasing, and rebooting it with a CV boot kit before the joint is damaged.
Belt Slippage and Clutch Maintenance
A wet or worn belt will cause slippage, resulting in a loss of power and a distinct burning smell. Thanks to the snorkels, a wet belt is less common, but it can still happen. More often, slippage is due to a glazed or worn-out belt.
Regularly remove the clutch cover to blow out any dust and inspect the belt for glazing, cracks, or flat spots. A spare belt and the tools to change it are essential items to carry on the trail.
Pro Tips for Maximum Performance and Longevity
Ready to move beyond basic maintenance? This section of our 2020 cod polaris sportsman 850 high lifter guide covers best practices that separate the pros from the amateurs.
Tire Pressure Secrets for Different Terrains
Don’t just set your tire pressure and forget it. For deep, sloppy mud, airing down to 3-4 PSI can dramatically increase your tire’s footprint and traction. For hard-packed trails or rocky terrain, airing back up to 6-8 PSI will provide better handling and protect your rims.
Winch Maintenance You Can’t Afford to Skip
Your winch is your get-out-of-jail-free card. After a ride where you used it, pull the entire cable out, clean it, and wind it back onto the spool neatly and under slight tension. This prevents binding and damage. Also, check the electrical connections to the winch for corrosion.
Understanding Your On-Demand AWD System
The Polaris On-Demand AWD is one of the best systems out there, but it needs the correct fluid to work properly. Using the wrong fluid in the front differential can cause the 4×4 system to engage slowly or not at all. Always use Polaris Demand Drive Fluid.
The Sustainable and Eco-Friendly Approach to Off-Roading
Being a true off-road enthusiast means respecting the environment we love to play in. A sustainable 2020 cod polaris sportsman 850 high lifter isn’t about compromising performance; it’s about responsible ownership.
Responsible Trail Riding: Tread Lightly
An eco-friendly 2020 cod polaris sportsman 850 high lifter approach starts on the trail. Stay on designated routes to prevent erosion. Avoid sensitive areas and cross streams only at designated crossings. Pack out everything you pack in.
Proper Fluid Disposal and Maintenance
When you change your oil and other fluids, never dump them on the ground. Collect them in a sealed container and take them to an auto parts store or local recycling center. They will dispose of it properly, often for free.
Extending Component Life to Reduce Waste
The best practices we’ve discussed don’t just save you money; they reduce waste. A well-maintained machine has parts that last longer, meaning fewer old parts end up in a landfill. Proactive care is the most sustainable practice of all.
Frequently Asked Questions About the 2020 COD Polaris Sportsman 850 High Lifter
What kind of oil is best for the Sportsman 850 High Lifter?
The manufacturer strongly recommends using Polaris PS-4 Full Synthetic 5W-50 engine oil. It’s specifically formulated for the high-performance demands and temperature ranges of the ProStar engine. In a pinch, a high-quality synthetic 5W-50 from a reputable brand can work, but sticking with the OEM fluid is the safest bet.
How often should I clean the relocated radiator?
You should rinse the radiator after every single muddy ride, without exception. A deep clean, where you gently spray from the back to push debris out, should be done at least every 2-3 rides or whenever you notice engine temperatures creeping up.
Can I add bigger tires without other modifications?
The High Lifter comes with 29.5-inch tires, which are already quite large. Going up to 31 or 32-inch tires will likely require clutch modifications (a clutch kit) to adjust the engagement and prevent excessive belt wear. You may also put additional strain on your axles and differentials, so proceed with caution.
What are the first signs of a worn CV axle?
The classic sign is a loud clicking or popping sound when you are turning sharply. You might also feel a vibration at certain speeds. A visual inspection is key—look for torn boots, as that’s the leading cause of failure.
Your 2020 COD Polaris Sportsman 850 High Lifter is an incredible piece of engineering, built to take on the toughest terrain. By following this guide and committing to proactive maintenance, you’re not just fixing problems—you’re preventing them.
You’re investing in countless hours of future fun and ensuring your machine is always ready when the mud calls your name. Now, get out there, ride hard, and stay safe!
