ABN Automotive Coolant Flush Machine - Air and Water Combo Coolant Backflush Gun - Multi-Size Nozzle...

Our Experience

Not gonna lie, I almost didn't buy this ABN coolant flush machine due to its price tag. For under $30, I expected a cheaply made tool that wouldn't last beyond a couple of uses. Boy, was I wrong.

After three weeks of regular use – I've got an old car that needs some TLC – the gun has been holding up great. It's well-built, sturdy, and feels like it could handle being knocked around in my cluttered garage.



The water and air combo did a fantastic job clearing out old coolant residue from my radiator. I especially liked how easily I could switch between nozzle sizes to accommodate different vehicles.



However, there's one minor critique: the pressure regulator can be finicky at first. It took me a few tries to figure out the right setting for my car without making a mess or not getting enough flush. Once I got the hang of it though, it was smooth sailing.
