Review on 🔧 Enhance Cooling System Maintenance with ATD Tools 3300 Pressure Test Kit by Jason Cho

Always works. I have used other testers where the pump leaks and gives inaccurate results. Not this one. I have tested the cooling systems on many domestic, Japanese and European vehicles with this kit and it works perfectly. The pump keeps the pressure, the adapters fit perfectly. Take the guesswork out - find leaks and fix them the first time. Be sure to check your repair - if something is seriously leaking there may be other leaks that you won't see until the big leak is fixed.
