Preparing for Winter: Essential Tips for Your Generator

As winter approaches, unpredictable weather can bring power outages. A reliable generator can be a lifesaver, but proper preparation is key to ensuring it runs smoothly through the colder months. Here is how to winterize yours.

Conduct a thorough inspection

Before winter, check for leaks, cracks, dents, or other damage, paying close attention to hoses, seals, and gaskets that may need replacement. Test the battery, replacing it if weak, and consider a trickle charger to maintain charge during inactivity.

Clean and replace filters

• Air filter: a clogged filter restricts airflow and reduces efficiency. Replace per the manufacturer or more often in dusty conditions.
• Fuel filter: a clogged filter restricts fuel flow and hurts performance. Replace it as part of your winter prep.

Fuel maintenance

Stale fuel clogs lines, causes poor combustion, and can damage the engine. Drain old fuel and refill with fresh, high-quality fuel. Consider a fuel additive to stabilize it and prevent gum, varnish, water contamination, and corrosion.

Winterize the cooling system

Ensure the cooling system has the correct coolant mixture for expected temperatures; low coolant can cause overheating and engine damage. In extremely cold regions, add antifreeze per the manufacturer's recommendations.

Protect against the elements

Invest in a weatherproof shelter or enclosure to protect against snow, ice, and extreme temperatures, and ensure proper insulation with adequate ventilation to prevent exhaust buildup.

Test run and load testing

Start the generator before winter and let it run for an extended period to confirm it works. Load testing simulates the demand it will face during an outage, uncovering weaknesses under load.

Proper fuel storage

Store fuel in approved containers and rotate your supply regularly, since fuel has a limited shelf life even with additives.

Schedule professional servicing

Many tasks can be done by the owner, but have a professional service the generator at least once a year to catch issues, perform repairs, and keep it at peak efficiency.
