Upgrade Options
Quick-Start Flow Valve: Diverts coolant to your heater core at low engine temps so you get warm air twice as fast. Ideal for cold-start riding.
Idle Pump: Circulates coolant even at idle so the heater works when you're stopped or moving slowly.
Grille Cover: Blocks cold air flowing over your radiator to raise coolant temps faster. Made from PVC-backed polyester. For use in temperatures below freezing only — do not use above 32°F or engine overheating may occur.
Second-Row Heater: Keeps rear passengers warm. Mounts in front of the middle seat with its own adjustable temperature and fan controls. Note: may limit center-rear passenger legroom.
Defrost Your Windshield
The included defrost vent and hoses route through your dash for a clean, factory-style look. Keeps your windshield free of snow, ice, and fog while you drive.

Frequently Asked Questions
Does this heater work on the Can-Am Defender MAX HD9?
Yes. This kit fits both standard and MAX HD9 Defender models from 2022 and newer that do not have a factory HVAC system. Select the appropriate heater position (Front, Rear, or Front & Rear) when ordering.
Does the SuperATV cab heater drain the battery?
No. The heater draws heat from your engine coolant lines, not from the battery. It only uses 3.4 amps at 13.7 volts for the fan — minimal electrical draw.
What is the Quick-Start Flow Valve and do I need it?
The flow valve diverts coolant to the heater core at low engine temperatures, so you get warm air much faster after startup. It's especially useful in very cold climates or when you need heat quickly. It is optional but highly recommended for cold-weather riding.
Can I use the grille cover in all temperatures?
No. The grille cover is designed for use in temperatures below freezing (32°F / 0°C) only. Using it in warmer temperatures will cause your engine to overheat.
Will the second-row heater fit all Defender HD9 configurations?
The second-row heater mounts in front of the middle rear seat. It may limit space for the center-rear passenger. It is compatible with Defender MAX models that have a rear seating row.
Is drilling required for installation?
Yes, drilling through plastic is required. All necessary drill bits, mounting hardware, hoses, and instructions are included in the kit.
