Confirm your year and trim against the fitment list in the description before ordering.
Your Can-Am Defender HD5 can handle winter, but that doesn’t mean you want to freeze behind the wheel. SuperATV’s Cab Heater pulls heat from your engine’s coolant lines to warm your cab just like the heater in a car. Installation is simple because the kit connects to your Defender HD5’s key-on and power terminals. We include hoses, drill bits, and machine-specific mounting plates to help you finish the job fast. Adjustable temperature and fan controls might even make winter your favorite season to ride.
Defrost Your Windshield
The heater unit has two built-in vents, plus we include a defrost vent and hoses to keep snow, ice, and fog off your windshield. The defrost vents route through your dash for a clean, factory-style finish.
Keep Your Cab Comfortable
This cab heater helps you stay comfortable every time cold weather hits. Its high-grade radiator hoses can withstand temperatures from -40°F to 285°F. Your heater and its components can handle extreme engine heat and bitter outdoor temperatures. It doesn’t just improve your ride—it makes winter a whole lot better.
Get Heat in Half the Time with a Quick-Start Flow Valve
Cut your heater’s warm-up time in half with a quick-start flow valve. It directs all engine coolant to the heater core while engine temperatures remain low. The valve opens automatically after the engine reaches operating temperature and allows coolant to flow through the radiator.
Add an Idle Flow Pump for Hot Air in About 30 Seconds
An idle flow pump can deliver heat to your cab in as little as 30 seconds. The pump maintains coolant flow through the engine for faster heat at idle or low speeds.
| Quick-Start Flow Valve | Idle Flow Pump |
| Gets you heated air twice as fast | Warms up heater in under 30 seconds |
| Diverts coolant to your heater core at low temps | Actively pumps coolant at idle to increase heater temps |
| Combine our Quick-Start Flow Valve and Idle Flow Pump for maximum heat as quickly as possible when you’re slow or idle. | |
Add a Grille Cover
Block icy airflow across your radiator with a grille cover. Higher coolant temperatures help your cab heater warm up faster. Our grille cover uses PVC-backed polyester and installs or removes with ease. It works so well that you can’t use it above freezing temperatures, or your machine could overheat.
