The Hecat Coolant Pulsator will quickly scrub the internals of the cooling system with its high frequency, high flow, and hard hitting "water hammer" pulsing action; removing scale, sludge, sediment, casting sand, and other deposits. The included accessories provide for easy access to flush the heater core, radiator, and block. The flushing gun has a variable flow rate and a trigger lock that can be employed for hands free flushing, as long as necessary.
