How to Winterize a Generator
Do you own a portable generator or a standby generator? It’s important that you know how to winterize a generator by following a few simple guideline:
How to Winterize a Portable Generator:
- Use a premium fuel stabilizer and run engine for 10 minutes to circulate.
- Drain oil from crankcase; replace your oil filter and refill with new oil.
- While engine is running, spray premium fogging oil until you see heavy smoke. Now, shut off generator.
- Remove spark plug and apply fogging oil as thick layer over hole.
- Inspect all screws, nuts, fasteners and clamps to ensure they’re secure.
- Inspect generator for any damaged parts and replace, if necessary.
- Store in safe, dry place for winter months.
How to Winterize a Standby Generator:
- Check your battery and be sure your battery is not low or dead. A low battery reading may become a bigger problem. When in doubt, replace the battery.
- Buy a cold weather kit with battery heater for temperatures below 40 degrees.
- An engine block heater heats engine oil for optimal starting.
- Follow manufacturer’s recommendations’ if you have an electrical heater that maintains coolant temperature.
- If you have a diesel engine below 1 liter per cylinder, use glow plugs which take air into combustion chamber; or, air inlet heater that heats the air needed for cooling and combustion.
- To prevent condensation on control panels, use AC powered, anti-condensation control panel heater.
- A winter grade blend with additives prevents gelling (follow manufacturer’s recommendations at all times). Fuel line and storage tank heaters are two other ways to keep fuel at temperature.
A good rule of thumb is always maintain your generator, both in summer and in winter to prevent an emergency situation when the power unexpectedly turns off. Northeast Generator’s friendly staff is always here to help with your questions on maintenance and replacement parts (203) 336-3031.
