Review on Astro 78585 Universal Radiator Pressure by Glen Elevyn

This thing has already saved me money and time. F'n Retard on YouTube who claims it's not 100% effective must be the dumbest person ever. Because this thing is awesome! I wish I had it much sooner. But it doesn't matter if you're servicing cooling systems. It is necessary! Ability to pressure test the system to detect leaks. Makes repairs easier and saves a lot of time when a customer has a dirty @ss engine and you need to see where it's leaking. You can also create a vacuum so you don't have air in the system and spend all that time poking open the heater core - a huge plus! Especially in vehicles with two radiators.
