The only freon available is R134a. Your car most like came with R12. That means it will have to have the system evacuated at a shop, and then be converted to the R134a. Look at the fittings where the freon is to be introduced to the system....if they are screw on, then your car needs to be changed over to the newer refrigerant....if they are quick connects, you simply need to add R134a.
On the low side. There should be two caps, one marked with an H and one marked with an L. Use the one marked with an L
Hye Bobby=-=The low port is either on or next to the receiver dryer or shiny can looking thing at the rear of the engine compartment. If you get too much in it won't cool as well. You really need gauges to see how much to add. GoodluckJoe
If you are using the little cans found in auto parts store attach adapter to low pressure side of A/C system to add charge. R134-A systems have different size valves to make it impossible to mix up the hi and low pressure sides.
The 1990 Chevrolet S 10 pickup truck 4.3 liter air-conditioner compressor can hold five pounds of Freon. Most Freon recharge kits will tell you when the Freon is full. If the system was void of any oil it would probably take 8 to 10 ounces of oil for proper lubrication. If you are only replacing the compressor, add three ounces to the suction port and be sure to turn the compressor by hand several turns clockwise after installation to disperse the oil through the pump. The refrigerant it takes to fill that system is more like 30 to 36 ounces not 5 pounds.
You don't add Freon as it has R134a not Freon. You add it to the low pressure side which is the larger hose.
Take it to the a auot shop. you can not add freon
Contains no Freon. Freon was banned beginning in 1996.
Answering "Where do you add freon to your air conditioner in your ford ranger?"
where do I add freon to my air conditioning unit on a 1997 chevy truck?
You add freon to the low side fitting,top front,on the ac compressor
In order to buy freon you need a license, therefore you shouldn't attempt to add freon. Call a contractor to service your unit.
You call a licensed contractor and have them check your system. If they determine that it needs freon, they can add the right punt.
You can add freon on the low side service port that is located on the accumulator next to the firewall................
You add freon to the a/c by using the low side, suction side (larger hose).............
Because they no longer use freon.
