Did this to my 98 Malibu v6, the low pressure valve is on line beside fire wall behind engine, it has blue protective cap on it. high pressure valve you would not use has red cap on it located beside radiator/condenser. You don't say what year your Malibu is so this may not apply to you if your unit uses the R12 refrigerant.
Buy a kit at Wal-Mart or auto parts comes with instructions
The recommended freon capacity is 1.75 lbs
where do I add freon to my air conditioning unit on a 1997 chevy truck?
low side charging is on passenger side , between engine and firewall. about a fot down. if not there check near the right shock tower, there should be a" L" on the cap,
