Snap-on RADKITULTRA Cooling Refill & Retention Tool – All-in-One Radiator Service

Revolutionize your cooling system service with the Snap-on RADKITULTRA. This professional-grade tool is a game-changer for technicians, combining both "Coolant Refill" and "Retention" capabilities into a single, sleek unit.

Product Story: Stop wasting time and money by draining entire cooling systems for simple component swaps. The RADKITULTRA uses a powerful vacuum to "retain" coolant in the engine, allowing you to replace thermostats, temperature sensors, or radiator hoses without losing a drop of expensive fluid.

When it’s time to fill, the dual-port design allows you to switch to "Refill" mode instantly. It pulls a deep vacuum to eliminate those stubborn, hard-to-reach air pockets that cause overheating and engine damage. Featuring a 5' exhaust hose to direct mist away from the vehicle and a rugged, protective gauge boot, this tool is built for safety, speed, and shop-floor durability.
