Generac Cold Weather Kits
Start with one question: is the generator air-cooled or liquid-cooled? Air-cooled home units usually need a battery warmer and oil heater. Larger liquid-cooled generators use real coolant heat.
Air-cooled home standby
Battery + oil heat
Choose the manufacturer kit listed for the unit’s kW tier and serial number. The battery warmer preserves cranking power; the thermostatic oil heater reduces drag.
Liquid-cooled generator
Engine coolant heat
Match the heater to the exact engine and voltage. These systems may use an immersion, tank or circulation heater and should remain ready automatically.
Find the right kit without guessing
- 1Record the generator model and serial number from its data label.
- 2Confirm air-cooled or liquid-cooled in the owner's manual.
- 3Check which cold-weather accessories are already installed.
- 4Match the OEM kit to the unit's generation and kW range.
- 5Have a qualified installer handle wiring or coolant work outside your experience.
- 6Test the complete system before the forecast storm arrives.

Quick questions
Does every Generac need a cold weather kit?
Not every climate does, but Canadian installations exposed to temperatures below the generator's specified operating range benefit from the correct OEM kit. Match by model and serial number.
Is the battery warmer enough?
It solves only the cranking-power problem. Air-cooled kits commonly pair battery warmth with an oil or crankcase heater so the engine also turns more easily.
Do liquid-cooled Generac generators use the same kit?
No. Liquid-cooled units can use engine coolant or block heaters sized to the engine. Order from the generator model, engine and serial number.
For portable and non-Generac machines, use the broader generator block heater guide.
