Hisun heater kits built for the Hisun 400, 500 or 700
Ice Crusher builds three heater kits for the Hisun 400, 500 or 700. Each kit is designed around the machine, runs on engine coolant so there is no battery drain beyond the fan, and ships complete with hardware, hose, fittings and picture-rich instructions — backed by unlimited phone support from Minnesota.

Frequently asked questions
What does the MaxStat do, and should I add it?
The MaxStat is our inline coolant bypass thermostat. It adds 10 to 15 degrees of cab heat by keeping hot coolant moving through the heater core, and it stops the engine thermostat from cycling open and closed so quickly, so the heat in the cab stays steady instead of rising and falling. It is a checkout option on every Hisun kit.
Does it defrost the windshield?
These are compact two-vent heaters that warm the cab. They do not have dedicated defrost vents; call us if windshield defrost is a must for you.
Will it drain the battery?
No. The heat comes from engine coolant; the fan draws about what a factory blower does.
Is everything I need in the box?
Yes. Heater, vents, hose, fittings, hardware, specialty tools and picture-rich instructions, plus unlimited phone support at 888-964-0135.
Do I need the hose clamp-off tools?
No — you can install the kit without them. But they make the job significantly cleaner and quicker, because you don't have to drain the coolant before cutting into the radiator hoses: clamp the hose off on each side, make the cut, and very little coolant is lost and very little air gets in. They are a $24.99 option at checkout on the kit page.
