How to Winterize Your UTV: Off-Season Storage Checklist

A side-by-side that sits all winter without prep can greet you in spring with a dead battery, gummed-up fuel, cracked hoses and a nest in the airbox. Twenty minutes of work in the fall avoids most of it. This checklist covers how to store your UTV for the off-season, and how to set it up if you plan to keep riding through the cold.

Step 1: Clean it thoroughly

Mud and road salt hold moisture against metal, rubber and wiring all winter. Wash the machine, including the undercarriage, wheel wells and radiator fins, then let it dry completely before storage. Clean the CVT intake area and check the air filter while you are at it.

Step 2: Deal with the fuel

Fuel left sitting for months can degrade and leave deposits in the fuel system. Two common approaches:

• Stabilize and fill: add a fuel stabilizer, fill the tank to limit condensation, then run the engine for several minutes so treated fuel reaches the injectors or carburetor.
• Follow the manual: some manufacturers recommend a specific fuel or procedure. Check yours.

Step 3: Change the oil before storage

Used oil contains contaminants and acids. Changing the oil and filter before storage means the engine sits in clean oil all winter. If you are close to a service interval for the front and rear differentials or transmission, do those too.

Step 4: Check the coolant

Make sure the coolant mix protects against the coldest temperatures in your area. A cheap coolant tester takes the guesswork out. Look for cracked hoses and loose clamps while you are there.

Step 5: Look after the battery

Cold and time are hard on batteries. A battery that slowly discharges over winter can be damaged and may not recover.

• Clean the terminals and check the connections.
• Connect a battery maintainer, or remove the battery and store it somewhere cool and dry on a maintainer.
• A jump pack in the garage is a handy backup in spring.

Not sure which you need? Read battery maintainer vs charger.

Step 6: Tires, belt and suspension

• Inflate tires to the recommended pressure. If possible, get the weight off the tires with stands to help prevent flat spots.
• Inspect the CVT drive belt for glazing, cracks and missing cogs. Spring is a bad time to discover a worn belt. See 7 signs your drive belt needs replacement.
• Grease any fittings on the suspension and driveline per your manual.

Step 7: Keep pests out

Mice love a quiet machine. Block the exhaust outlet and the airbox intake with a rag or plug (and leave yourself a reminder to remove it), avoid leaving food in the cab, and consider deterrents around the storage area.

Step 8: Cover it properly

Indoors, a breathable cover keeps off dust and protects plastics. Outdoors, you need a waterproof cover with tie-downs that will not flap and scuff the paint. A cover that traps moisture can do more harm than good, so look for vents. Our UTV cover buying guide explains storage vs trailerable covers.

Riding through winter instead?

If you use your UTV for plowing, chores or winter trails, set it up for the cold instead of storing it:

• A roof, windshield and doors or a full cab enclosure make a huge difference.
• A cab heater turns a cold commute into a comfortable one.
• A plow kit gets real work done. See how to choose a UTV snow plow kit.
• Check tire tread and consider traction for ice and packed snow.

9. Cover with a breathable or waterproof cover as needed.

Frequently asked questions

Should I leave my UTV gas tank full or empty for winter?

Many owners fill the tank with stabilized fuel to reduce condensation and run the engine so treated fuel circulates. Some manuals specify a different approach, so follow your manufacturer.

Can I start my UTV once a month during storage?

Short starts that do not fully warm the engine can create condensation in the oil and exhaust. If you start it, run it long enough to reach full operating temperature, or simply keep the battery on a maintainer.

Do I need to remove the battery for winter storage?

Not if the machine is stored somewhere it will not freeze hard and the battery stays on a maintainer. In very cold unheated storage, removing it and keeping it on a maintainer indoors is safer.

What is the best cover for outdoor UTV storage?

A waterproof, UV-resistant cover with vents and secure tie-downs. Model-specific covers fit better and flap less in the wind.

Ready for spring

Winterizing is boring, but it is the cheapest maintenance you will ever do. When spring comes, pull the plugs, reconnect the battery, check the tires and run through a pre-ride inspection before the first ride. Shop UTV covers to finish the job.
