Enhance your vehicle's A/C performance with this innovative Enviro-safe Arctic Air and Stop Leak kit designed specifically for R1234yf systems. This dual-action aerosol solution combines two powerful products in one convenient package. It effectively removes moisture from your A/C system, preventing potential corrosion and freeze-ups while reducing friction for improved cooling efficiency. The kit includes a specialized gauge that connects to both the can and your vehicle's R1234yf low-side port. Note that the can features a 134a top, requiring appropriate connection hardware. Compatible with most automotive refrigerants (except ammonia and CO2 systems), this product installs just like standard refrigerant but cannot be added to a fully charged system. For optimal results, follow the installation guidelines carefully. Please note: This product cannot be shipped to Alaska, Hawaii, or international destinations except in pallet quantities.
