Polaris Water Bleed Upgrade Kit – Pro XP / Turbo R / Pro S / Pro R

Upgrade your cooling system reliability with the Polaris Water Bleed Upgrade Kit for Pro XP, Turbo R, Pro S, and Pro R models. Factory water bleed systems use a plastic quick-disconnect Bundy style fitting that can fail or come loose, potentially allowing coolant to drain without warning.

This Pro XP and Turbo R water bleed upgrade kit replaces the vulnerable factory fitting with a durable 303 stainless steel -4 AN water bleed fitting. The result is a stronger, more secure coolant connection that helps prevent unexpected coolant loss.

Designed for performance and reliability, this Polaris coolant bleed upgrade is ideal for aggressive riding, racing, and high-heat applications where cooling system integrity is critical.
