Reliable Cold Weather ATV Operation

Cold temperature preventive maintenance ensures ATVs run at peak performance throughout the winter riding season. While motorcycle, scooter, boat and jet ski owners in northern climates have packed away their equipment until spring, ATVs provide owners with year-round recreational and work opportunities. However, ATVs operated in cold winter climates require special attention to ensure reliable operation throughout the season. When conventional lubricants get cold, they tend to thicken and sacrifice wear protection, while synthetic motor oils maintain their viscosities in cold temperatures. Owners traveling long distances at high speeds may wish to contact their ATV dealers regarding jetting requirements. Because cold air is denser than warm air and has higher oxygen content, a richer fuel mixture is required to prevent piston damage. In addition, check into whether gasoline antifreeze is recommended for the ATV and ensure the air filter is clean. If the ATV is equipped with a heated carburetor, have a dealer inspect its operation. When conventional lubricants get cold, they tend to thicken and sacrifice wear protection, while synthetic motor oils maintain their viscosities in cold temperatures. "Synthetic oils do not need to be confined to the engine and transmission," says Randy Hall of MX Performance. "Differentials will also benefit from the characteristics of synthetic gear oils especially in the cold weather." Grease the steering and suspension linkage to remove dirt and water contaminants, and inspect driveline and CV boots to avoid problems with freezing water. Drum brake seals should also be inspected to be sure they are in place, ensuring drums don't fill with water and freeze. Brake fluid can also become contaminated with water and freeze in cold weather. If the brake fluid has not been changed in the last five years, it may be time to change it. Because a cold engine requires more electrical energy to turn over, and because a battery's chemical action slows in cold weather, winter is an especially trying time for an ATV's electrical system. Using the winch as a lift for a plow system taxes the electrical system even further. If an ATV's battery is between 3-5 years old, have it checked or replaced. It is also a good idea to check the charging system. Ensure the battery terminals are clean and tight, and make sure the battery's electrolyte level is at the proper height. In liquid-cooled machines, it is important to ensure the concentration of antifreeze is at the correct level. Temperature protection should be lower than the lowest temperature the operator expects to ride in during the season. Check the condition of the hoses and radiator as well. Finally, before hitting the trails, always make sure the ATV has had a chance to warm up. If riding on roads where salt is used, protect the undercarriage and metal components with a rust inhibitor. Formula 4-Stroke® Power Sports Synthetic Motor Oil The broad 0W-40 viscosity rating of AMSOIL Formula 4-Stroke® Power Sports Synthetic Motor Oil (AFF) provides the ultimate extreme temperature protection for ATV engines and transmissions, ensuring easy cranking, excellent cold weather starting and quick post-startup protection in the coldest winter climates. Propylene Glycol Antifreeze and Engine Coolant AMSOIL Propylene Glycol Antifreeze and Engine Coolant (ANT) provides maximum antifreeze and cooling protection in the most extreme temperatures and operating conditions. Heavy Duty Metal Protector AMSOIL Heavy Duty Metal Protector (AMH) is excellent as an undercoating, protecting metal surfaces exposed to the damaging effects of salt, moisture or chemical corrosion.
