Review on 🧪 ABN Deluxe Antifreeze and Coolant Tester Hydrometer Tester: Reliable Automotive Tool for Ethylene Glycol Coolant Testing by Brent Peterson

Rubber ball so thin that it hardly absorbs any liquid. You have to fiddle with it to make it pump liquid. Who has time for that. It's annoying that whoever made this thing didn't care if it worked or not. Not a professional tool or a decent DIY tool. I have the same one that I have had for thirty years. It recently broke so I removed the lightbulb so the new one would work better. The rubber bulb on my old one was twice as thick and drew out liquid with a very quick positive effect. The tube should be about 2-3 inches longer. The gauge needle on this new one is also sticky and doesn't like to move smoothly. I have to shake it and tap it to make it work. I like that the scale goes down to -45. It's also pretty cheap, but some are better made. I really don't really trust him because he's so sticky. Be sure to look elsewhere.
