Generac 6559 – Frequently Asked Questions

1) What actually comes in the Generac 6559 cold weather kit?
Two heating components plus the hardware to mount them: an engine block heater with all necessary mounting hardware, and a battery warmer with the thermostat built into the battery wrap. Instructions are in the box. You do not need to source a separate thermostat or control.
2) Do I need a cold weather kit on my standby diesel generator, or is it optional?
Generac recommends these kits for generators installed where temperatures regularly drop below 32 F (0 C). Below that, cold oil and a cold battery are what cause hard starts on a standby unit that has to crank on demand. If your site rarely sees freezing, the kit is optional; in a northern climate on a life-safety or critical-load install, it is the difference between the set starting and not.
3) Is there anything else I have to do when installing the Generac 6559 kit?
Yes, and it is easy to miss: when a cold weather kit is installed, the engine oil is required to be changed to 5W-30 synthetic for better start capability. Budget the oil change into the same service visit as the kit install.
4) What power does the Generac 6559 battery warmer draw, and do I need a dedicated circuit?
The battery warmer runs on 120 volts and pulls 75 watts, 0.63 amps. That is a small load a 120V utility circuit at the generator can carry, but the block heater in the kit is a separate load, so size and plan the supply for both rather than for the warmer alone.
5) How does the battery warmer know when to turn on?
A thermostat is built into the battery wrap itself. When the temperature falls below an acceptable level, it energizes the warmer and holds the battery at a temperature that supports starting, then drops out again. Nothing for the installer to set or wire as a separate control.
6) Is the Generac 6559 a block heater only, or does it cover the battery too?
Both. Some cold weather accessories are engine block heaters alone; the 6559 pairs a block heater with a thermostatically controlled battery warmer, so the engine oil and coolant side and the cranking power side are both addressed. If you only bought a block heater, a cold battery can still leave you short on cranking amps.
7) What is the Generac part number for the 30 kW Protector diesel cold weather kit?
Order Generac model 6559. That is the manufacturer part number for the cold weather kit covering the 30 kW Protector series diesel generators.
8) Where is the Generac 6559 cold weather kit made, and are there shipping restrictions on it?
The 6559 kit is made in the United States and carries no shipping or sale restrictions, which matters for agencies and institutional buyers working under domestic sourcing preferences.
