Loading... Please wait...Polaris Northstar (HVAC) models rely on a serpentine belt to drive the A/C pump and alternator—and without a belt tensioner, proper installation requires the correct tool. These model-specific HVAC belt tools are engineered to safely guide and stretch the belt onto the pulleys without damaging the belt or components. Simply route the belt, position it on the tool and A/C pump pulley and rotate the tool to smoothly guide the belt into place. Made from billet steel and plated for long-term durability, these tools deliver OE-level performance at a more cost-effective price and are proudly made in the USA.
