There's nothing fun about spilling coolant all over your engine bay and driveway or waiting in the cold for your engine to warm up while you bleed air from the cooling system. That's why Mishimoto wants to help you avoid all of that and fill your cooling system in two easy steps. With this coolant vacuum purge and refill tool kit, you can simply connect the tool to a compressor, pull a vacuum on your cooling system, then open the valve and fill. No air to bleed out and no sitting in the cold while you wait for your engine to get up to temp. The Mishimoto Coolant Vacuum Purge and Refill Tool Kit includes a universal compression-style adapter and collars to fit most coolant tanks or radiators and comes packed in a convenient carrying case. Like all Mishimoto tools, this coolant vacuum purge and refill tool kit is backed by our Mishimoto Lifetime Warranty for a lifetime of service.
