If your generator is housed outside the facility, check for ice dams or buildups that might obstruct air intakes and exhaust, preventing adequate venting and airflow.

If there is a lot of snow or several cycles of freezing and thawing, ice or snow might build up and cover these locations, preventing the generator from working. While items can be installed to reduce the buildup, it’s still vital to check these places regularly to ensure they’re free of any blockages.

4. Remove the Spark Plug

How to Winterize a GeneratorIt’s critical to remove the spark plug since it can cause your generator to misfire, resulting in costly repairs. Driving with misfiring spark plugs can place undue strain on the generator. To prevent dust or debris from entering the engine, several manufacturers recommend removing the spark plug and closing the aperture. 

Disconnect the spark plug from the spark lead to keep it in good condition. Also, remove any debris from the area around the spark plug to avoid it going into the engine’s combustion chamber.

5. Test the Generator

Testing the generator is vital as it will enable you to know if your generator is functioning or not. This will make you know if it can start quickly and run smoothly or has accumulated a few hinges that need repair and replacements.

Ensure your generator is tested at least twice before the manifestation of the winter period to avoid panic when you realize it does not function as previously.

6. Change Oil & Filter

Adding new oil to the generator will guarantee that the generator’s moving parts are lubricated over the winter. This will also guarantee that engine wear particles and sludge are removed, as dirt particles can cause engine damage. 

Dirt can corrode an engine over time, shortening its lifespan. Oil also degrades and becomes “sludge” over time. As a result, it’s critical to keep the engine clean by changing the oil and filters regularly, as this helps to remove particles and sludge and keeps engines in top shape.

7.  Get a Cold Weather Kit

The use of a cold-weather kit is one of the simplest ways to winterize your standby generator. To assist their generators function more efficiently throughout the winter, most manufacturers produce cold weather kits tailored to their models. Your local generator expert can advise you on which cold weather kit is best for your generator and even help you winterize it.

 8. Check all Fluids

This is an essential step for anyone planning to store their diesel portable generator for the winter. Fluids, in other words, are critical for extending the life of portable generators significantly.

Checking the fluid levels of anti-freeze coolant, for example, is critical since it ensures that your portable generator is stored correctly and will not rust due to freezing temperatures.

9. Clean and Grease the Generator’s Surface

Polishing the generator’s surface is an excellent way to maintain it clean before storing it and to protect it from rust, which could cause internal engine components to be damaged. It’s also a good idea to grease interior components and ensure they’re properly lubricated.

If you have a dual-fuel generator and have only run LPG, it isn’t necessary to clean the carburetor, fuel lines, or tank. However, if you have run the generator on both fuels, you must clean the tank, inspect the lines, and clean the carburetor. Propane will not leave residue in the lines as it burns relatively clean. Disconnect propane before storing.

10. Give it Time

When a portable generator is exposed to freezing conditions for more than a few hours, the interior components will become cold, and in some cases, frozen.

In this situation, one must be cautious of the dangers. There’s a good chance you’ll kill a portable generator if you start it cold after it’s been lying outside for the whole day in sub-freezing temps.

On frosty mornings, there’s a reason you should let your car engine warm-up, right?

Portable generators are the same way. They must be turned on and left unplugged for atleast 15 to 20 minutes. This way, the engine and fluids will warm-up, lubricating all internal components and preventing such an expensive piece of machinery from breaking down.

11. Install a Battery Warmer

Installing a battery warmer is another approach to reduce battery loss in cold weather and keep power to start your generator. The battery warmer activates when the temperature reaches a specified level, preventing the battery from draining.

Bottom Line

We come to an end to the discussions about how to winterize a generator. This is a practice that you will never be able to argue against putting into place. It is necessary and the most reliable technique to ensure proper operation during the harsh winter months.

It extends the generator’s life winterizing and allows it to last longer and perform better. Similarly, it fails less frequently and requires fewer repairs. This ensures that the device is continuously operating at its full potential.
