This kit combines a battery warmer pad (7101) and oil heater pad (7102) to address the two biggest cold-weather challenges: battery drain and thick oil viscosity that prevents smooth engine starting.
The standout feature is the automatic thermostatic control system that activates at 40°F and deactivates at 55°F, eliminating the need to remember turning heaters on during freezing weather. Real-world testing confirms this works flawlessly, with verified customers reporting immediate starts in sub-zero conditions after years of hard-start problems. The 50-watt dual heating system maintains optimal oil temperature while protecting battery capacity, directly addressing the overcrank issues common in older Generac units.
Installation is straightforward with a plug-and-play design that integrates with existing generator components. Most users report completing setup in under an hour with basic hand tools. The kit includes both heating elements, harnesses with Y-splitters, and clear instructions. One practical note: the oil heater sleeve fits snugly over the filter, so take care during future oil changes. Also, bring your own zip ties as the included ones are reportedly fragile.
The primary limitation is compatibility, as this kit only works with air-cooled Generac generators from 2008 onward in the 9-22kW range. Liquid-cooled models are not supported. Additionally, Generac recommends switching to 5W-30 synthetic oil after installation for optimal cold-weather performance. AGM-style batteries do not require the battery heater pad.
For homeowners seeking affordable winter protection for compatible Generac generators, this kit delivers exceptional value and proven reliability at roughly one-fifth the cost of official Generac solutions. The automatic operation and dual-system approach make it a practical choice for reliable standby power during the coldest months.
This cold weather kit is specifically designed for Generac air-cooled standby generators in the 9kW to 22kW power range manufactured in 2008 or later. It directly replaces OEM part numbers Generac 7101 (battery warmer pad) and Generac 7102 (oil heater kit).
Compatible models include most residential standby generators from Generac's air-cooled lineup within this wattage and year range. However, this kit is NOT compatible with liquid-cooled Generac generators, portable generators, or models manufactured before 2008. If you own a 2024 Generac 24kW model, customer feedback confirms successful installation is possible, though verify your specific model before purchasing.
The battery heater pad is specifically designed to fit under the generator battery and is not required if your unit uses an AGM-style battery. When in doubt, consult your Generac documentation or contact Generac support with your model number to confirm compatibility before ordering.
Installation requires only basic hand tools and typically takes less than one hour. The kit includes both the battery warmer pad and oil heater pad with pre-assembled harnesses featuring Y-splitter connectors for easy integration. Step one involves opening the customer connection end of the generator housing to access the connection points.
Route the included cables carefully to avoid sharp edges or moving parts. The oil heater sleeve slides over the oil filter, while the battery pad positions under the generator battery. Connect both harnesses to the main connector using the N1/N2 connector pins, which simply push into place. Secure cables with zip ties (bring your own quality ones as the included ties are reported to be fragile).
The kit includes installation instructions, and numerous YouTube videos document the process for various Generac models. Once installed, the thermostatic control automatically activates heating when ambient temperature drops below 40°F and shuts off at 55°F, requiring no further user intervention. After installation, Generac recommends switching to 5W-30 synthetic oil for optimal cold-weather performance.

Who Should Buy This Cover: Homeowners with backup generators, contractors with outdoor equipment, and anyone seeking reliable all-weather protection for mid-to-large size generators. Ideal for areas with frequent rain, intense sun, or harsh seasonal weather.
Key Considerations Before Purchasing: Measure your generator's length, width, and height before ordering. This cover runs large, making it better suited for generators at the higher end of the 6,000-13,000 watt range. If your unit is smaller or has an unusual frame design, verify compatibility or consider a smaller cover size.
Installation and Use: The cover features intuitive fastening with clearly marked straps and Velcro points. For operational use, lift the front curtain panel to access fuel and exhaust, then secure side Velcro closures. For storage, fully enclose the unit and tighten all straps. In windy conditions, tension all straps firmly to prevent displacement.
Maintenance: Rinse the cover periodically with mild water to remove debris and bird droppings. Allow to air dry completely before storage. The included carrying bag should be used for off-season storage to maintain material integrity.
Warranty and Support: Verify current warranty terms with the manufacturer. Quality construction suggests good longevity, but proper fastening and seasonal maintenance will maximize the cover's lifespan.
Buying Guide: Choosing Winter Storm Protection
1. Storage Cover vs. Running Enclosure
The most critical decision is whether you need a simple storage cover or a full running enclosure. A basic storage cover, like the Champion Power Equipment Weather-Resistant Storage cover, is ideal for keeping a dormant generator clean and dry. It’s a cost-effective solution for seasonal protection.
For active storm use, you need a dedicated running enclosure. These products, such as the GenArmor or IGAN tents, are engineered with frames and ventilation to safely house an operating generator. They allow for exhaust flow and provide access panels for refueling and maintenance without exposing the unit to the elements.
2. Material Durability and Weather Ratings
Look for specific ratings for snow load, wind resistance, and waterproofing. The DuroMax DMX-GTX cover is rated for extreme conditions, including high wind speeds and significant snow accumulation. Heavy-duty tarpaulin and reinforced frames are common in top-tier models.
Fabric density, measured in denier (like the 900D fabric used by SORLANX), indicates thickness and tear resistance. Welded seams, as found on the Champion Storm Shield, are superior to stitched seams for preventing water ingress. These features ensure the accessory won’t fail when you need it most.
3. Compatibility and Fit
Always check the wattage range and physical dimensions before purchasing. Most running covers, like the IGAN models, are designed for a broad range of portable generators. However, a universal storage cover may have more flexible sizing. Accurate measurement of your generator is essential.
For internal components like the Cold Weather Kit for Generac, compatibility is even more precise. These kits are designed for specific generator brands and models. Verify your generator’s make, wattage, and model year to ensure a proper fit and safe operation. Explore our portable generators category for more information on different models.
4. Ease of Use and Installation
During a storm, you don’t want to struggle with a complicated setup. Many premium enclosures advertise tool-free, three-step assembly. Features like flip-top refueling doors and roll-up side panels, as seen on the Rimwig cover, add significant convenience for ongoing operation and maintenance.
Consider storage as well. A cover that folds compactly into a carrying bag, like the 900D Heavy-Duty Waterproof Generator cover, is much easier to store when not in use. This practical aspect ensures you’ll actually use the accessory season after season. For other essential gear, our generator accessories hub is a valuable resource.
Final Thoughts
Preparing your generator for winter storms is a non-negotiable part of responsible ownership. The right accessory can mean the difference between reliable heat and light and a cold, dark home. For most users seeking robust, all-weather protection for an operating generator, the GenArmor Generator Tent Cover while Running offers an excellent balance of durability and features. If you own a compatible Generac standby unit and face deep freezes, the targeted warmth provided by the Cold Weather Kit for Generac is an invaluable investment for ensuring a sure start. Stay safe and powered up this season.
Frequently Asked Questions
Can I use a regular tarp to cover my running generator?
No, this is extremely dangerous. A standard tarp will trap exhaust heat and fumes, leading to a fire hazard and potential carbon monoxide poisoning. It also blocks necessary airflow for cooling. Always use a cover specifically designed and rated for running generators, which includes proper ventilation and heat-resistant materials.
Do I need a cold weather kit if I have a running cover?
They serve different purposes. A running cover protects the generator’s exterior from snow, rain, and wind. A cold weather kit, like the one for Generac, protects internal components by keeping the oil and battery at optimal temperatures for starting and operation. In severely cold climates, using both provides the most comprehensive protection for your generator system.
How do I measure my generator for a cover?
Measure the length, width, and height at their maximum points. Include any protruding handles, wheels, or fuel caps. Compare these dimensions to the interior dimensions listed for the cover, not just the wattage range. A cover that is slightly larger is better than one that is too tight, but an excessively large cover may not secure properly in high winds.
Are these accessories useful for other types of emergencies?
Absolutely. While optimized for winter, waterproof running enclosures are equally vital for operating a generator during heavy rainstorms or hurricanes at any time of year. A quality cover also protects against UV damage, dust, and debris during prolonged storage. Investing in this gear enhances your preparedness for any power outage scenario. The principles of fuel type and preparedness are further discussed in our fuel types guide.
