I am wanting to inject coolant into my 1999 Taurus. I bought the kind that has the hose attached. I was wondering if there was a specific way to proceed, as I have heard a couple variations. Someone told me to dip the cans in warm water and to shake cans periodically. The specs say I need approximately 34-36 oz so I bought 4 cans, how should I store any left overs? I live in AZ so it's very hot here right now. Is it safe to store in garage? Any advice would be appreciated.
