Which do i hook to to charge the freon in a 2004 ford expedition
R134a
R134a
I had an additive put in my Lincoln ls. I bought the adapter needed to add freon. It was located on driver side in front of tire.
on the low side pessure port of the compressor line
Freon is added in the low pressure port of the ac system. It is on an aluminum pipe on the passengers side, close to the ac drier.
You add Freon on the low side with the motor running. The low side connection port for freon is much smaller in size compaired to the high side, so you can't put it in on the high side. If you are a novis at this, I suggest you buy the charge kit with a gage so you don't over fill the system,(if you over fill it it won't work properly)
Buy a kit at Wal-mART OR AUTO PARTS COMES WITH INSTRUCTIONS
Go to Walmart or an auto parts store. Buy an a/c recharge kit for R134 freon coolent. Follow the directions on the can..
You don't add Freon as it has R134a not Freon. You add it to the low pressure side which is the larger hose.
