Freon is a very touchy thing to work with. The EPA bans its release into the atmosphere, so only experts and professionals know how to add and subtract Freon from the car safely. Take your car to a mechanic or a Chevy dealer for this.

You can add Freon to your 1999 Chevy cooling system through the low pressure port. Connect your Freon bottle to the low pressure port and release the Freon into the system.
The schrader valve on the low pressure side of the system.

You can add power steering fluid to your 1988 Chevy Astro by removing the top to the power steering fluid reservoir. Pour the fluid directly into the reservoir.
You always add freon using a set of gauges and you would use the low side (blue knob), if you are not using gauges then still use the low side service port but make sure that its a freon problem first...........
Go to your local auto parts store. They will have kits with directions for you to do the job at home.
