How do you put freon in delta 88?

Answer 1

Year? Just a brief suggestion, it will be difficult to find Freon and if you do, it is expensive. The newer refrigerant, 134a, is much more readily available and far cheaper. In general, connect your charging aparatus (whichever type you have) to the LOW side of the refrigeration system. Two lines lead from the compressor. One goes to the condenser (the radiator looking coil that's in front of the regular radiator) and the other line goes to the receiver/dryer. The line that goes to the receiver/dryer is the low pressure side. There should be a port somewhere near the receiver/dryer, that's where you connect to add refrigerant. You'll need a gauge to know when to stop, and you may need to jumper the low pressure switch that is on the side of the receiver/dryer, otherwise it will take forever to get enough refrigerant to start getting the system to pump.

Answer 2

Check on the radiator support or hood and make sure your car uses 134 coolant. Anything newer than 1990 or so should use it. Older cars need adapter fittings added to the old fittings so that the 134 hose will attach.

The low pressure side of the system is the smaller diameter fitting on the hose. You can't hook it up to the wrong side. You can either get a hose to connect the can of freon to the AC and reuse it or get a can of freon with the hose already on it. The hose attaches the same way an air chuck goes in an air hose. Attach the can and hose to the AC line, start the car and turn the AC on, puncture the can and the freon should go into the system. You may have to shake the can a bit. If you hold the can upside down, it will go in faster but it should go in regardless. If the system is completely empty, 2 cans should be enough. Most brands of Freon have stop leak in them for small leaks. This is for O ring leaks and small ones. Ther may be a larger leak that requires repair.
