This SuperATV cab heater for Can-Am Defender fits Can-Am Defender HD7 models and draws heat from the engine coolant lines to warm your cab and clear the windshield, the same way a car heater works. It wires to the Defender HD7's key-on and power terminals and gives you adjustable temperature and fan speeds for cold-weather work and trail days.
The kit includes the heater unit, hoses, drill bits, mounting plates, wiring components and the machine-specific hardware for the Defender HD7. Options add a grille cover, a quick-start flow valve and an idle flow pump.

FAQ
How much heat does this Can-Am Defender HD7 cab heater put out?
SuperATV rates the heater as capable of 14,600 BTU at 135 CFM. It pulls heat from the Defender HD7's engine coolant, like a truck heater, so output builds as the engine warms up.
Will it keep my windshield clear?
Yes. Along with the two 360° adjustable vents on the unit, the kit includes a defrost vent and hoses routed through the dash to keep snow, ice and fog off the windshield.
Which Defender HD7 models does this heater fit?
SuperATV lists Can-Am Defender HD7 DPS: 2022+. Fitment on unlisted models is not guaranteed.
How much power does it draw?
The heater draws 3.4 amps at 13.7 volts. It ties into the Defender HD7's key-on and power terminals, so it only runs when the machine is on.
Is drilling required to install the heater?
Yes. You drill through plastic in a few spots. SuperATV includes the drill bits, hoses, mounting plates and instructions, and the official install guide is linked on this page.
Quick-start flow valve or idle flow pump: which one do I need?
The quick-start flow valve sends all engine coolant to the heater core at low engine temps and cuts warm-up time roughly in half, then opens on its own once the engine is warm. The idle flow pump actively circulates coolant so you get heat in about 30 seconds, even at idle or slow speeds. SuperATV recommends combining them for the fastest heat.

SuperATV builds each Can-Am Defender heater kit around the machine it fits, with Defender HD7-specific mounting plates and wiring that uses the Defender's own key-on and power terminals.
