Review on 🔧 Efficient R134A Valve Core High Low Pressure Tool for Automotive Air Conditioning: SY66 Quick Remover Installer by Patrick Gibb

As other buyers have mentioned, the product works well if you gently squeeze the end of the valve core tool so it is snug against the valve. Each buyer should evaluate the valve size (low side or high side) by removing the midshaft valve tool and checking the valve for leaks before proceeding. This tool saves home mechanics a lot of money by working from home and avoiding the mechanic's workshop.
